: 2. Economic benefits of planting rape flowers

1. Natural factors

The growth of crops is greatly influenced by natural factors, and soil conditions, weather conditions and climate factors in planting areas will directly affect the yield and quality of crops. As far as rape is concerned, natural factors will directly affect the yield of rape. China's rape planting area is very large, and many areas are suitable for rape planting. Although with the continuous development and progress of agricultural production technology in China, the impact and threat of drought, precipitation, pests and diseases on rape planting is still inevitable. For example, Qinghai province has a plateau climate and cool temperature, which is very suitable for rape planting. Rape has always been the most suitable crop in most areas of Qinghai Province, with obvious advantages of high yield, disaster resistance and cultivation. However, due to the influence of global climate change and other factors, the plateau climate has also appeared larger? In this case, a series of natural factors, such as water shortage and climate warming, have changed, and the yield of rape has dropped sharply, which directly affects the economic benefits of rape planting.

2. Market factors

Since China joined the WTO, the trade between China and the international market has become more and more frequent, and the proportion of trade has also shown a diversified development trend. In the rapeseed market, a large number of foreign low-priced rapeseed poured in, and the demand for local rapeseed dropped sharply, which eventually led to great changes in the relationship between supply and demand of rapeseed. From the price point of view, it can realize the effective adjustment of rape planting. In the actual adjustment process, we must pay attention to farmers' economic income and ensure that farmers have enough enthusiasm for rape planting and sufficient market supply. In addition, the government can adopt a series of economic policies to regulate rape planting, which can also achieve good regulatory effect. The agricultural policies of China and the United States have always paid more attention to the production of major food crops, but not to cash crops such as rape, and there is no corresponding policy support, which ultimately affects the effectiveness of rape planting.

3. How should the rape flower industry develop?

Brassica napus is a regulator often used by people, which has a good effect on increasing yield. However, some farmers are somewhat vague about the true usage of brassinolide, which leads to misunderstanding when using brassinolide, leading to the problem of ineffectiveness or yield reduction.

Brassica napus is widely used in field crops, fruits and vegetables. It can promote cell division, enhance vegetative growth and reproductive growth, improve flowering and fruit setting rate and increase crop yield. Many farmers say that since Brassica has been widely used, why is there any misunderstanding?

1. Brassica is different from foliar fertilizer.

Chinese cabbage and rape can be used for seed dressing and foliar spraying. When it is sprayed as foliar, many farmers often use it as foliar fertilizer. We commonly use foliar fertilizers such as amino acids, potassium dihydrogen phosphate, borax, chelated calcium and so on. Mainly used to supplement the nutrients needed for plant growth. However, brassinolide is different from foliar fertilizer, which contains no nutrients and mainly plays a regulatory role. Therefore, the two cannot replace each other. However, some farmers have asked why they are often mixed with fertilizers such as nitrogen, phosphorus and potassium, because they are not foliar fertilizers.

Brassica napus can promote cell division, and mixed with foliar fertilizer can improve nutrient absorption and promote crop growth. For example, in the later stage of peanut growth, the ability of root system to absorb fertilizer is weak. Spraying rape and potassium dihydrogen phosphate can prolong the functionality of upper leaves, prevent premature aging and promote pod maturity.

The mixture of rapeseed and foliar fertilizer is a good formula to increase production. In addition, brassinolide can be mixed with some neutral or acidic pesticides, such as brassinolide plus pyraclostrobin plus potassium dihydrogen phosphate, which can prevent diseases and increase production.

Don't blindly increase the dose.

Many crops have reduced production because of growing in adversity, so in this case, the use of brassinolide can increase the resistance of crops and has obvious regulatory effect. If the crop itself grows stronger, it may not be able to directly see the use effect, and farmers will ignore its role and start to increase the dosage and use times of chemicals. Excessive use of brassin will also affect the growth of crops. Generally, it is used for 2~3 times in the whole growth process.

When corn is planted in summer, some plots will have short ears and lack of grains, mainly because the pollination period is high in August. If a variety with poor heat tolerance is planted, the yield will be reduced. If 1-2 times of brassin is sprayed at the early stage of maize growth, the stress resistance of maize will be improved and the influence of temperature on maize pollination will be reduced.

Spraying Brassica napus on crops is effective, but its effect cannot be exaggerated. It can be mixed with other fertilizers or pesticides to achieve good results. When using, we should also pay attention to the dosage of different crops to avoid excessive situation.

1. Water for drought resistance

Timely drought-resistant watering is the key measure to ensure early planting and strong seedling of rape. In fields with irrigation conditions, build drainage gaps in the fields, flood them with large water until they are flush with the border surface, and then drain the water to create moisture for transplanting and planting and promote the growth of seedlings. It can also be adapted to local conditions. After planting, thoroughly irrigate the planting water, then artificially irrigate the live rape trees every morning and evening, and then irrigate them every other day according to the development of drought.

Combined with drought resistance, 30- 100 times of poplar root amino acid and humic acid solution were applied to rape roots to promote root growth and improve rape stress resistance.

2. Apply sufficient base fertilizer.

For fields that have not been fertilized or lack of basic fertilizer in the early stage, divide them into two or three plots or apply 44%( 19- 18-7) Sinochem compound fertilizer of 25-30 kg/mu. After dry fertilization, the border must be watered and permeable.

4. Current situation of rape flower development

Rape flower is fragrant, and natural rape flower is sweet.

Flowers bisexual, 4 petals arranged in a cross. Stamens usually have 6, 4 long and 2 short, which are usually called tetrastrong stamens. The pistil consists of two carpels, and the ovary is located on the upper side. Stems cylindrical, much branched; Leaves alternate, large, dark green, without petiole and stipules; In March and April, there are flowers, racemes, 4 calyxes, yellow-green, and 4 yellow corollas at the tip of the stem, which are cross-shaped. The fruit is silique. When summer is ripe, it cracks and scatters seeds, purple, black and yellow.

Rape flower has four petals, neatly surrounding the stamens, and its personality is simple. The petals are so delicate that no skilled sculptor can carve them. The stamens in the middle are bent together, as if whispering. Its roots are tough, its leaves are thick, and it is as simple and rough as the farmers who grow them.

Extended data

The development of rape industry in China Rapeseed is the most important oil crop in China, and its seed oil content is 33%~50%. Since 1995, the annual planting area is100000 mu, and the annual output of rape is nearly1000000 tons, accounting for 40% ~ 45% of the total output of oil crops (excluding soybeans); At the same time, it also produces about 6 million tons of rapeseed meal. The protein content of the cake is as high as 40%. The amino acid composition of rapeseed protein is reasonable, and the lysine content is equivalent to that of soybean, while the sulfur-containing amino acids such as lysine and methionine are higher than that of soybean protein. It is the largest high-quality feed protein source to be developed and utilized in China.

Rapeseed can be used to extract edible oil and feed, and can also be used to make margarine and artificial protein in food industry. It is also widely used in metallurgy, machinery, rubber, chemical industry, paint, textile, soap making, paper making, leather, medicine and other industries, and has important economic value.

5. How to promote the development of rape flower industry?

(1) Strengthen the basic position of agriculture and increase support for grain production. In accordance with the requirements of coordinating urban and rural development, increase investment in agriculture, rural areas and farmers, focus on farmland water conservancy, comprehensive agricultural development and rural infrastructure construction, guide the rational allocation of various production factors and resources, strive to improve the comprehensive agricultural production capacity, and change the weak agricultural infrastructure as soon as possible; By optimizing the structure to increase income, we will continue to do a good job in the planning and construction of advantageous regional distribution of agricultural products, increase support for the development of grain production, promote the intensive processing of agricultural products, and form a benign interactive pattern of increasing agricultural efficiency and increasing farmers' income.

(2) Vigorously cultivate industries with distinctive advantages and continuously expand leading agricultural enterprises. First, give full play to regional advantages and make characteristic agriculture bigger and stronger. It is necessary to classify policies and focus on promoting and expanding the development of emerging industries such as sightseeing agriculture, facility agriculture and brand agriculture. Thereby forming scale development benefits. Taking the construction of key high-quality commodity grain and characteristic agricultural products as a breakthrough, we will focus on strengthening the support of agricultural science and technology and promote the upgrading of modern agricultural industry. Second, around the regional layout of agricultural production in the city, based on advantages, accelerate the construction of agricultural industrial belt, implement large-scale, standardized and intensive production, and enhance the ability of radiation driving. Third, develop and expand a number of agricultural products deep processing enterprises, promote the transformation and appreciation of agricultural products, further enhance the level of agricultural industrialization and improve agricultural production efficiency. Fourth, vigorously develop green agriculture, take market demand as the starting point and improve efficiency as the foothold, promote agricultural standardized production and comprehensively improve the overall quality of agriculture.

(3) Standardize the management of agricultural resources market. The increase in the prices of agricultural means of production has greatly reduced the benefits brought to farmers by various subsidies and rising food prices. Therefore, measures must be taken to strengthen the supervision of the ex-factory prices and circulation links of agricultural means of production such as fertilizers, further stabilize the prices of agricultural means of production, reduce production costs, severely crack down on the manufacture and sale of fake and shoddy agricultural means of production, and strictly control the price costs and market pricing of agricultural means of production, so as to truly benefit farmers and protect their interests. Relevant departments should comprehensively standardize the supervision mechanism, standardize the agricultural resources market, strengthen supervision over the supply, price and quality of agricultural resources, reduce farmers' business risks and production costs, and guide farmers to use farmyard manure more.

(4) Continue to increase investment in agriculture and subsidies to farmers, further optimize the agricultural industrial structure, and comprehensively improve the comprehensive agricultural production capacity. According to strict policies and regulations. Current situation of two subsidies

6. How to promote the healthy development of rape flower industry?

The cost of 200 mu of rape a year is probably the cost of buying rape seeds, fertilizer, renting land and wilding, which is about 20 thousand a year. The average yield of 200 mu is about 800- 1000 kg. According to the market price of three yuan a catty, the seed income of planting 200 mu of rapeseed is about 240 thousand-300 thousand yuan. Excluding capital, this 200 mu of land can only earn1.5-200 million.

7. Benefits of rape flower cultivation

The rapeseed in Qinghai, Gansu is the best!

Spring-sown rapeseed in China is mainly distributed in Inner Mongolia, Xinjiang, Qinghai, Gansu and other northwest provinces. Rapeseed sowing in autumn and winter is mainly concentrated in Zhejiang, Jiangsu, Anhui, Hubei, Jiangxi, Hunan, Chongqing and other provinces. Sichuan, Chongqing, Yunnan, Guizhou, Jiangsu, Zhejiang and Shanghai are rich in rapeseed. Due to the differences of climate and soil in different places, the annual harvest time of rape is also different. Generally, the upper reaches of the Yangtze River are about 15 days earlier than the middle reaches.

8. How to promote the healthy development of rape flower industry in rape flower producing areas?

Present situation and prospect of planting industry in China. Talk about three aspects.

First, the main achievements of China's planting industry development

In recent years, under the guidance of Scientific Outlook on Development, the government of China has made solving the "three rural issues" the top priority of all its work, and put forward the overall plan for coordinating urban and rural development and the "three rural issues" policy. Give less and get more, give more and get more, and introduce a series of direct and powerful policies to support agriculture and benefit farmers, including abolishing agricultural tax, special product tax and animal husbandry tax, and implementing grain subsidies, improved crop subsidies, agricultural machinery purchase subsidies and comprehensive agricultural subsidies. Farmers, this has greatly mobilized their production. Under the guidance of these policies, the development of planting industry in China came into being.

A rare good situation in history. To sum up, there are six main achievements:

First, grain production has achieved recovery development. Since 2004, grain production has maintained a good momentum of sustained growth, reversing the situation of continuous decline in the previous five years. Mainly reflected in three aspects: first, the grain planting area has increased steadily. In 2006, it reached 65.438+0.582 billion mu, with a cumulative increase of 96.5438+0./kloc-0.90 billion mu from 2004 to 2006. Second, the unit rate of return reached a record high. In 2006, the yield per mu reached 3 14.4 kg, with an increase of 25.6 kg in three years. Third, the total output grew rapidly. In 2006, it reached 995 billion Jin, an increase of 654.38+033.7 billion Jin in three years. This year is expected.

Increase production for four consecutive years, and grain output is expected to exceed 1 trillion Jin.

Second, cash crops have continued to grow steadily. In 2006, the cotton output reached 6.75 million tons, and the sugar output reached 654.38+0.10.00 billion tons, both of which were the highest levels in history. The oil yield has broken through history for three consecutive years. At the same time, the output of economic crops such as vegetables, fruits, tea and cocoons increased, the total output increased, the quality was optimized, and exports increased steadily.

Very long. The coordinated development of crops and cash crops is also rare in history.

Third, the regional production pattern has taken shape. The production of superior products is increasingly gathering in space, and a number of specialized production areas with distinctive characteristics and obvious advantages have emerged. Nine dominant industrial belts with rice, wheat, corn and soybean accounting for 86%, 92%, 62% and 53% respectively have been initially formed. Cotton has formed three major cotton areas, namely, the Yangtze River basin, the Yellow River basin and the northwest inland, accounting for 98% of the country's total area. The rape industrial belt in the Yangtze River basin accounts for 85% of the whole country. There are three sugarcane industrial belts in central and southern Guangxi, southwestern Yunnan and western Guangdong, accounting for 89% of the country. Bohai Bay and Northwest Loess Plateau, two major apple industrial belts, account for 88% of China. There are three major citrus industries in the middle and upper reaches of the Yangtze River: sweet orange, fresh navel orange in southern Jiangxi-southern Hunan-northern Guangxi and wide orange in southern Zhejiang-western Fujian-eastern Guangdong.

It accounts for 49% of the country.

Fourth, the competitiveness of horticultural products has been continuously enhanced. China horticultural products have obvious competitive advantages in the international market. Since China and China joined the WTO,

Fifth, new progress has been made in the transformation of development mode. By actively promoting the development of resource-intensive and environment-friendly agriculture, the development mode of planting industry is changing from extensive to intensive. First, the application field of improved varieties has been further expanded. The comprehensive quality rate of the four major grain varieties reached 61%; The promotion area of insect-resistant cotton accounts for 70% of the total cotton area; Double-high sugarcane and double-low rapeseed reached 90% and 80% respectively. Second, the utilization rate of agricultural inputs has been further improved. High-efficiency fertilization, high-efficiency pesticide application and farmland water-saving technology have been widely used, which not only effectively promoted cost saving and efficiency improvement, but also played a positive role in protecting the ecological environment. At present, the application area of high-efficiency fertilization technology, mainly based on soil testing and formula fertilization technology, has reached 640 million mu, equivalent to one-third of China's cultivated land area. Third, the quality and safety level of fresh agricultural products has been further improved. Through continuous improvement of routine monitoring, dynamic management, product certification and quality traceability system, edible horticultural products such as vegetables, fruits and tea are in the market.

Pesticide residues are effectively controlled.

Sixth, the planting function is expanding day by day. On the one hand, planting, as the basic industry of agriculture, has the functions of ensuring effective supply and increasing farmers' income to further increase farmers' income. On the other hand, the functions of planting in ecological protection, sightseeing and leisure are increasingly apparent. In the suburbs of some large and medium-sized cities, planting has become a green city.

Color barrier and sightseeing agriculture have become new growth points for farmers to increase their income.

Second, the outstanding problems faced by the planting industry in China

Although China's planting industry has made great achievements, it is still in the stage of transformation from traditional planting industry to modern planting industry, and there are some difficulties and problems. Can't be ignored. Mainly in five aspects:

First, resource constraints are tightening day by day. The shortage of resources is the basic national condition of China. In recent years, with the increase of population and economic development, the demand for agricultural products has been increasing. At the same time, the contradiction between cultivated land and water resources is more prominent, which has become a prominent problem restricting the development of planting industry. The main contradiction of cultivated land is the shortage of total amount and the decline of quality. The per capita arable land area in China and China is 1.39 mu, which is only 1/3 of the world average, and it is still decreasing year by year. Two-thirds of the existing cultivated land is medium and low yield, and there are problems such as nutrient imbalance, decreased fertilizer efficiency and serious degradation. The main contradiction of water resources is insufficient total amount, uneven distribution and low utilization rate. The per capita water resources of China and the United States are less than 2,000 cubic meters, which is only 1/4 of the world average. The annual precipitation in summer accounts for more than 70% of the whole year; The cultivated land area north of Huaihe River accounts for nearly 2/3 of the whole country, but the water resources are less than 1/5 of the whole country. At the same time, due to the low utilization efficiency of water resources, the average output of agricultural irrigation water per cubic meter, per mu and per millimeter is 1 kg of grain.

0.5 kg of grain is produced by precipitation, which is only half the level of developed countries.

Second, the threat of agricultural disasters has intensified. China is one of the countries with frequent natural disasters. In recent years, under the influence of global warming, meteorological disasters and diseases and insect pests have occurred seriously, which has an increasing impact on crop production. In terms of meteorological disasters, the affected area of crops is more than 700 million mu every year, accounting for about 1/3 of the total sown area of crops, and the disaster rate is about 50%. Due to meteorological disasters such as drought, flood, typhoon and low temperature freezing, the grain loss is about 654.38 billion Jin, and the direct economic loss of agriculture is more than 654.38 billion yuan. According to the statistics of our Ministry, in 2004, China lost 6 1 100 million Jin of grain due to meteorological disasters, which reached 69 billion Jin in 2005 and increased to 89.4 billion Jin in 2006. From 65438+ this year 10 to September.
