Question 1: What vegetables are suitable for planting in autumn (9 ~165438+1October) and winter? Chinese cabbage, white radish, cowpea, snap beans, spinach, coriander, purple cabbage, Chinese cabbage, celery, autumn eggplant, chrysanthemum, lettuce. Winter (Gregorian calendar 65438+February ~ February) vegetables, Chinese cabbage, spinach, lettuce, carrot, coriander, lily, radish, mustard, garlic, ginger, onion 222,,, and planting time are suitable for early spring planting, some in early autumn and some in summer. Every vegetable has a certain planting time. Early planting does not necessarily germinate, and late planting does not last long. Therefore, like many things in life, we must grasp the time when planting. The easiest way is to buy rapeseed to be planted in the second year in the first autumn. At present, planting time, growth period and planting points are generally marked on seed bags for reference. So you can plan the planting time for one year in advance. Of course, you can also ask local experienced farmers, and they will definitely tell you the planting time of local common vegetables. However, even if the problem can be solved so easily, we might as well know more about when to grow vegetables, because it contains many mysteries of nature! Each vegetable has different requirements for temperature, some like heat and some like cold; Their growing period is also long and short, and these factors determine their planting time.

Question 2: What vegetables are suitable for greenhouse cultivation in winter? Greenhouse vegetable planting technology (1): greenhouse construction

(1) Type and structure of scaffolding. There are many types and structures of plastic greenhouses. At present, there are two kinds of prefabricated galvanized thin-walled steel pipes (referred to as steel pipe greenhouses) and bamboo circular arch greenhouses. It is mainly used for early-maturing cultivation in spring and delayed cultivation in winter of tomatoes, sweet (hot) peppers, eggplants and cucumbers in Natsuna, as well as seedling raising and hybrid seed production. There is also a bamboo shed, which is often used alone or in combination with a greenhouse (that is, a shed is built on the greenhouse) for seedling raising and early cultivation of eggplant and melon vegetables in winter and spring.

There are two specifications for steel pipe greenhouses: one is that the center is 2.2 meters high, the width span is 4.5 meters, the length is 20 meters, and the area is 90 square meters; The other is that the center is 2.5 meters high, 6 meters wide and 30 meters long, with an area of 180 square meters. The service life is generally 15 years.

In order to reduce the production cost, bamboo shed can also be used. Scaffolding is made of bamboo or small logs, about 2 meters high and 4-5 meters wide, with a general service life of 3 years.

(2) Covering materials: Greenhouse covering materials are as follows:

1. Ordinary membrane: made of polyethylene or polyvinyl chloride, with a thickness of 0. 1mm, colorless and transparent. The service life is about half a year.

2. Multifunctional long-life film: it is made by adding proper amount of anti-aging materials and surfactants during polyethylene blow molding. The multifunctional membrane produced by Zhejiang Guangxin Plastic Factory has a width of 7.5 meters and a thickness of 0.06 mm, its service life is twice as long as that of ordinary membrane, and the greenhouse temperature at night is higher than other materials 1-2℃. Moreover, the film is not easy to form water droplets, with good covering effect, low cost and high benefit.

3, grass quilt, grass fan: woven from straw, good thermal insulation performance, is a night thermal insulation material.

4. Polyethylene high foaming film: it is a white plastic film with many bubbles, with a width of 1 m and a thickness of 0.4-0.5 cm. It is light and can be rolled up, and its thermal insulation is similar to that of grass quilt.

5. Non-woven fabric: a kind of polyester filament, which is not woven or spun. There are two kinds: black and white. They have different densities and thicknesses. The common specification is 50g/? In addition to heat preservation, it is often used as a sunshade net.

6. sunshade net: a plastic woven net. Commonly used are black and silver gray, and there are several density specifications with different shading rates. It is mainly used for sun protection and rain protection in summer, and can also be used for thermal insulation and covering in winter.

(3) Greenhouse construction: choose a place with sufficient sunshine, shelter, high dryness, good drainage and no soil infectious diseases to build a greenhouse.

(4) Maintenance of plastic film: When the film is fastened, the mechanical damage of the shed film, especially the bamboo shed, should be avoided as far as possible. Before the film is buckled, the protruding part of the frame surface should be flattened or wrapped with old cloth. When fixed with a spring, the card slot should be padded with an old newspaper. In addition, attention should be paid to avoid long-term contact between old and new films, so as not to accelerate the aging of new films. Be careful when ventilating.

If the film is frozen or exposed to the sun, it will promote aging. When the steel pipe is exposed to the sun in summer, the temperature can rise to 60-70℃, thus accelerating the aging and crushing of the film.

In the process of using the film, it is inevitable that there will be holes, so it should be repaired with glue or tape in time.

Second, the environmental characteristics and supervision

Because the greenhouse is covered with plastic film, it forms a special microclimate which is relatively closed and different from the open field. In order to cultivate vegetables in greenhouse, we must master the characteristics of greenhouse environment and take corresponding control measures to meet the conditions of vegetable growth and development, so as to obtain high quality and high yield.

(1) Environmental conditions in the greenhouse:

1. illumination: it depends on the solar radiation intensity outside the shed, the optical characteristics of the covering material and the pollution degree. The light transmittance of new plastic film is 80-85%, and the light transmittance of old film polluted by dust and soil is often below 40%. The water droplets condensed on the film surface can reduce the illumination in the shed by 10%-20% due to the diffusion of water droplets. The shed frame, the film pressing line and the frame material of tall vegetables will be blocked, so the factors that weaken the light in the shed should be avoided and eliminated as far as possible in the management of the shed.

2. Temperature:

(1) Temperature variation law: The daily variation trend of temperature in greenhouse is the same as that in open field, but the temperature difference between day and night changes greatly. There is plenty of sunshine during the day. If the temperature in the film closed shed rises rapidly, the highest temperature can reach 40-50℃, which is more than 20℃ higher than that outside the shed. The effect of warming in rainy days is poor, and the lowest temperature in the shed at night is generally higher than that outside the shed 1-3℃. The ground temperature in the shed is more stable than the air temperature, usually 10-20℃. The temperature in the greenhouse also changes with different locations. The greenhouse is horizontally distributed with high middle and low sides, so the plants in the middle of the greenhouse are often higher than those on both sides. Greenhouse is vertically distributed. The sun shines during the day, and the temperature is high and low, but it is the opposite at night and cloudy days.

(2) Inversion phenomenon: In a polyethylene-covered greenhouse, the temperature inside the greenhouse is sometimes lower than that outside the greenhouse on the night when there is a breeze and sunshine in winter. The reason is >>

Question 3: What vegetables and spinach are suitable for planting in autumn and winter?

Spinach can be planted in spring and autumn. Autumn sowing is the main growth period, about 60 days. Suitable places can be planted and harvested all year round. In northern China, there are also winter sowing and spring harvesting, commonly known as burying spinach, while in Australia, it may also be winter sowing and spring harvesting. Spinach has strong cold tolerance, and the optimum growth temperature is 15-20℃. The lowest temperature of seed germination is 4℃. Plants can endure low temperature below 0℃ for a long time, not high temperature, and grow poorly above 25℃.

Lettuce:

Lettuce vegetables, including oil wheat vegetables, lettuce and lettuce, are all cold-loving vegetables. The optimum temperature of lettuce seed germination is 15 ~ 20℃, the optimum temperature of seedling growth is 16~20℃, the heart leaves of head lettuce begin to curl or the tender stems of lettuce begin to elongate and thicken, and the optimum temperature of growth is 18 ~ 22℃. The optimum temperature for lettuce growth at heading stage is 20 ~ 22℃ during the day and 12 ~ 15℃ at night. Generally speaking, 10~ 15℃ at night at 20~25℃ before eclosion, and10℃ at 8 ~/0℃ after eclosion. Early sowing: 20 ~ 25℃ 12℃, after slow seeding: 18 ~ 22℃ during the day, and the minimum at night is not lower than 10℃.

Chinese cabbage:

Chinese cabbage likes mild and cool climate conditions, and the suitable growth temperature is 10? In the range of 22 degrees Celsius, it can't grow well above 25 degrees Celsius, and it can't adapt above 30 degrees Celsius. /kloc-It grows slowly below 0/0℃, stops growing below 5℃, and is resistant to light frost and heavy frost.

Mustard:

Mustard vegetables, including mustard, kohlrabi, mustard tuber, potherb mustard, potherb mustard and so on. Mustard likes cold and dampness, avoids summer and drought, and is slightly resistant to frost. The optimum temperature for mustard seed germination is 15~25℃. This kind of vegetables belongs to the winter crops sown in autumn and has a long growing period. The ten-day average temperature suitable for leaf growth is 65438 05℃, and the temperature suitable for edible organ growth is 8 ~ 65438 05℃. However, the formation of edible organs in stem mustard and cabbage mustard requires low temperature, and the temperature requirements for leaf mustard are not strict. In Australia, where the lowest temperature in winter is not lower than 0 degrees, planting mustard in autumn and winter is also the first choice.

Radish:

Radish can be divided into autumn and winter radishes, winter and spring radishes, summer and autumn radishes and four seasons radishes according to seasons. Radish is a semi-cold-tolerant plant, and its seeds germinate at 2℃ ~ 3℃, and the optimum temperature for germination is 20℃ ~ 25℃, and it can still grow normally at the seedling stage of -2℃ ~ 25℃. The optimum temperature for the growth of stems and leaves is 15c ~ 20c, the temperature range for the growth of fleshy roots is 6℃ ~ 20℃, and the optimum temperature is 18c ~ 20℃. Radish in autumn and winter is the most important radish.

Rapeseed:

The daily average temperature is 15- 18℃, and the optimum temperature is 20-25℃. The budding temperature is about 5℃, the bolting temperature is about 10℃, the flowering temperature is about 12-20℃, the optimum temperature is about 16℃, and no flowers will bloom below 5℃.

Folding vegetables:

Caibeng likes to be cool. Is the seed in 15? At 30℃ and 20? 25℃ is the optimum temperature for germination, 4? 8℃ is the lowest temperature, 40℃ is the highest temperature, and the suitable growth temperature is 18 ~ 20℃, which can resist the cold of -8- 10℃ and hinder the growth above 25℃. Varieties with low temperature resistance to ground collapse can be selected for autumn and winter cultivation.

8. Cabbage moss:

Include Chinese cabbage and red cabbage moss. The suitable temperature for the growth and development of Chinese cabbage rape is 15-25℃. Different growth periods need different temperatures, and the optimum temperature for seed germination and seedling growth is 25-30℃; The growth temperature of leaves is slightly lower, and the suitable temperature for cabbage moss formation is 15-20℃. When the daytime temperature is 20℃ and the night temperature is 15℃, the cabbage moss develops well, with high yield and good quality. China Province will be re-divided, including Xiangxi, Huaihua, Hengyang and Chenzhou. If the temperature is too high or too low, cauliflower is slender, with low yield and poor quality. Only a few places in Australia are suitable for growing cauliflower in winter. 9. celery:

Celery is a semi-cold-tolerant vegetable, which likes cool and humid climate. The lowest temperature of seed germination is 4℃, and the optimum temperature is 15-20℃. When the temperature is lower than 15℃ or higher than 25℃, the germination rate decreases, and the seedling growth temperature is 15-20℃. Cold tolerance and stress tolerance of seedlings-> >

Question 4: Can you grow vegetables in winter? Vegetables that can be planted in winter are: radish, cabbage, watercress, chrysanthemum, Shanghai green, leek, coriander, garlic sprout, onion, spinach, mustard, celery, cauliflower, oil wheat vegetable, pea and so on.

Green onion variety: According to the length of green onion, there are long onion and short onion. The scallions are spicy and thick, and the famous varieties are Liaoning Gaiping scallions, Zhangqiu scallions, Beijing Gaojiaobai scallions and Shaanxi hua county Valley scallions. The onion is short and thick, and the famous varieties are the chicken leg onion in Zhangqiu, Shandong Province and the opposite leaf onion in Hebei Province.

Cabbage varieties: Choose suitable varieties according to local climatic conditions, cultivation techniques and growth period, disease resistance and storage resistance of related varieties. Generally, late-maturing and middle-maturing varieties with high tree height are selected for plots with good fertilizer and water conditions, and short-growing varieties are selected for plots with poor fertilizer and water conditions.

Radish variety: White radish is the best radish variety cultivated in winter. Because the hypocotyl of white radish is thick, the tender stem is white or light green, and the leaves are green or light green, the cultivated seedlings are of good quality and high yield.

Variety of oil wheat vegetables: select excellent varieties with disease resistance and cold resistance, such as four-season oil wheat vegetables and fragrant oil wheat vegetables.

No matter what vegetables are planted in winter, we should first pay attention to choosing varieties with wide applicability and strong cold tolerance, which not only saves a lot of effort in management, but also reduces a lot of unnecessary troubles in planting.

Question 5: What vegetables are suitable for planting in winter? Chinese cabbage, radish and potatoes.

Green onion is a kind of vegetable and condiment that residents in northern China like to eat in winter. There are generally two traditional planting methods in the north: seedling raising in late autumn, planting in May-June of the following year or seedling raising in early spring. The harvest season of the two methods is usually from July to 10, and will be delayed until the Spring Festival after storage. Heze Institute of High-tech Agricultural Sciences, taking advantage of the strong cold resistance of green onions, explored and cultivated a new variety of cold-loving green onions and a set of new methods for off-season cultivation in the open field, which enabled green onions to be listed in the off-season from February to June and doubled their economic benefits.

The quality of Chinese onion is very good. Although Hanfeng green onions are planted out of season, the quality is still good. It is not like the common "pig excrement beans" in rural areas. In the case of suitable cultivation, the green onion can be as high as 40 ~ 50 cm, and the weight of a single plant is about 500 g. Onions are moderately spicy and slightly sweet, and are very popular with consumers in the market.

Off-season listing, attractive benefits. Because the marketing season of cold scallions is in the off-season of vegetables, the quality of winter scallions is declining, and fresh and tender cold scallions are particularly attractive to consumers. The market price has been very high in recent years, except in the spring of 200 1. Before May 1, the retail price of Chinese onion in Hanfeng was RMB 0.60 ~/kloc-0 ~ 2.00 per kilogram, and the price was also stable at RMB 0.60 ~ 1.00 per kilogram from May to July. Many farmers plant green onions in cold areas with a high income of 3,000-5,000 yuan per mu.

Small planting area and great market potential. Due to the late development time and small planting area, it is extremely rare to form a large-scale planting base in northern China, but the market sales volume is large. In addition, it is usually from September to April in the north, which is the winter leisure time of the land. After harvesting the cold-rich green onion, it will not affect the planting of other crops.

Precautions. 1. This variety is suitable for planting in parts of Henan, Shandong, Jiangsu, Anhui, Shanxi, Shaanxi and Gansu. The normal temperature in winter is below 15℃. 2. The seedling raising time can be from May to August, and the seedbed for planting one mu of Hanfeng Welsh onion is about 150 square meters. 3, timely sowing, strengthen water and fertilizer management after the Spring Festival, such as late harvest, to remove buds in time.

Question 6: What vegetables are suitable for planting in autumn and winter in South China? In autumn and winter, vegetables that like cold climate or overwinter are mostly roots (such as radish, carrot and onion), cabbages (cabbage, cauliflower and broccoli), beans (sweet peas, peas and broad beans) and green leafy vegetables (green vegetables, chrysanthemums, spinach, Chinese cabbage and lettuce).

Question 7: What vegetables are planted in winter? What vegetables are suitable for planting in winter?

1, leek: it can still survive at minus 5 degrees, and it can grow above 10 degrees, and it does not need strong light, so it is more suitable for balcony and indoor planting. But planting only means planting with leek roots. If you use seeds, I'm afraid you won't be able to eat leeks within three months. You can harvest 4-5 times a year.

2. Onion: You can grow it yourself, but you should be mentally prepared. They will grow slowly indoors or on the balcony, and they will be as thin as steel needles after a long time. It is best to plant it with onion roots to ensure that it can be eaten within 20 days.

3. Lycium barbarum: Cutting propagation.

4, coriander: planting with coriander roots will be several times faster than seeds, and it will grow more vigorously. It is a cold-tolerant vegetable and likes to be cold. The suitable growth temperature is 12℃-26℃, but it also has strong heat resistance.

5. Celery: planted with roots, celery is cold-resistant, heat-resistant, disease-resistant, grows fast, adapts to a wide temperature range, and has a strong celery flavor. A variety of crops can be planted at the suitable temperature of 15 ~ 20℃, and can be planted all year round if the basin soil is sufficient.

6, garlic seedlings: the simplest and fastest growing, 15 days can definitely be eaten.

7. Chrysanthemum morifolium: Planting with seeds, suitable growth temperature 17-20℃. The requirements for light are not strict, they are more resistant to weak light, prefer humidity, and are not strict with soil. So it is very suitable for planting in the north.

8. Mushrooms: It's better to plant them. The method is simple: take a thick inedible stem with 2-3 smiling faces, insert it in the soil, remember to water it and grow it into a big pot!

9. Spinach: heat-resistant, cold-resistant, fast-growing and disease-resistant. It is said that eating it will turn you into a strong sailor, but unfortunately I can't.

10, lettuce: heat-resistant, cold-resistant, bolting-resistant, and can be planted all year round.

Vegetables can be planted all year round: garlic, ginger and onions. Chinese cabbage, Chinese cabbage, spinach, cabbage, cauliflower and mushrooms can also be planted.

Question 8: What vegetables are suitable for growing in Beijing in winter? Vegetables suitable for indoor balcony planting in winter:

1. You can plant shallots in winter, but you should be mentally prepared. It will grow slowly indoors or on the balcony and remain as thin as a steel needle for a long time. It is best to plant it with onion roots and eat it within 20 days.

2. Vegetables can also grow leeks in winter. Leek is the favorite dish of northerners, also called "Qiyang Grass". Good leek is very beneficial to people's health, and this dish has the following characteristics: First, it can survive at MINUS 5 degrees and grow above 10 degrees, which is suitable for balcony and indoor planting. But planting only means planting with leek roots. If you use seeds, I'm afraid you won't be able to eat leeks within three months.

3. You can also choose coriander for growing vegetables in winter. When planting coriander, it is best to plant it with coriander roots that are several times faster than the seeds, and it grows vigorously, so that you can know your own coriander quickly.

If you want to grow some simple vegetables, you can also choose garlic seedlings in winter. The planting method of garlic seedlings is the simplest and the fastest. /kloc-garlic seedlings planted in 0/5 days are absolutely edible.

You can also plant some auricularia in winter. Auricularia auricula grows very fast in winter, so it is better to plant auricularia auricula with strings.

Question 9: What vegetables can be grown in winter? What vegetables can you grow in winter? Hot pot dishes can be used at a good price.
