The yield per mu of scallion can be as high as 10000 kg.
Many seedlings were transplanted in the green onion producing areas in northern China. Most of the main producing areas in the middle and lower reaches of the Yellow River are sown in autumn, but it is necessary to strictly control the number of seedlings before winter. Sow in spring in the south of the Yellow River. When the local temperature reaches 7℃, we should pay close attention to sowing. Onion is suitable for loam cultivation with pH6.5-7.5. Nursery needs loose fertilizer and sufficient soil moisture. Topsoil hardening should be prevented at seedling stage, topdressing should be done once when seedlings begin to grow rapidly, and soil moisture should be controlled 10- 15 days before planting to prevent the seedlings from lodging too quickly. Planted from June to July, the row spacing of Landrace is 70cm, the row spacing of Dwarf Landrace and Chicken Leg is about 50cm, and the spacing between plants is about 5cm. In order to increase the buried depth of pseudostems, the ditching depth of Landrace (below the ground) is 15cm, and that of Short Landrace is about 10cm. Loosening the bottom of the ditch, planting onion seedlings in the ditch, and burying them to a depth of 5-7 cm. 1000 kg Onion needs to absorb 2.7 kg of nitrogen, 0.5 kg of phosphorus and potassium for normal growth. When the hydrolyzed nitrogen in the soil is less than 80ppm in the growing period, it is necessary to topdressing the available nitrogen fertilizer. Supplementing phosphorus and potassium fertilizer can increase yield and improve quality. The management of high temperature season is mainly to prevent waterlogging, weed and protect seedlings, and the vigorous growing season requires sufficient soil moisture.
It is an important link of onion cultivation and management to cultivate soil to prevent the onion tree from lodging and soften the false stems. When the plants begin to grow vigorously and the height of the false stems exceeds the ground, topdressing should be used to level the furrow. When the false stem is about 10cm higher than the ground, cultivate the soil. Local varieties were cultivated twice, and the false stems were buried 30-40 cm deep. Short white and drumstick varieties are cultivated once, and the buried depth of false stems is about 20cm. If there is no soil cultivation in the growing period, the plants can be placed upright in the softened bed after harvest, and sand can be filled in the gaps of the false stems to keep the bottom of the bed moist and the upper part free from rain. Softening can be completed in 25 days in warm season and about 40 days in cold season. This method has great softening loss, but it can be planted in close density and easy to obtain high yield.
Green onions can adapt to a wide temperature range, and can be harvested and eaten from seedlings to bolting. In addition to cultivating fully grown scallions in autumn, other seasons also cultivate and harvest shallots (onions with insufficient nutritional growth).
Seed collection: There are two kinds of seed collection methods: adult and semi-adult. Seed collection in adult plants: The well-developed green onions in autumn are used as seed plants, which is convenient for strict seed selection, but the cost is high, so it is used when propagating the original seeds; Seed collection of semi-mature plants: semi-mature plants are planted in summer and before winter, with low cost and shortened cycle by one year. Welsh onion is easy to cross-pollinate, and seeds should be collected in isolation between varieties.
Collecting, planing and drying the green onions harvested in early winter, then bundling them and discharging them into shallow ditches in the shade. It can be stored at a low temperature below 0℃ for more than 100 days, and the onion bundles should be kept slightly frozen during storage to avoid repeated thawing. The air humidity should be about 80%, which can cover the grass for moisture and rain protection. Welsh onion has no natural dormancy characteristics. Although the pseudostem can be preserved for a long time at room temperature, it is very costly.
How much is an acre of green onions?
China Welsh Onion is a high-yield Welsh Onion successfully bred by Cao Xian County Diversification Office and Professor Liu Jieqing of China Agricultural University. Also known as "golden" onion, the maximum per plant can reach 1.5 kg, which can be harvested in the same year or the following year. 1996, Caoxian "China Welsh Onion" demonstration field 180 mu, yield per mu 10000 kg. I. Planting 1. Planting time: Spring scallion seedlings are generally planted from early June to early July. When the seedling grows to 30-40 cm in height and the transverse diameter is 1- 1.5 cm, it is suitable for transplanting. 2. Land preparation and ditching: After the previous crops (non-onion and garlic stubble) are harvested, the litter and weeds should be removed immediately, and farmyard manure 5000- 10000 kg and diammonium phosphate 30 kg should be applied, and ditching should be carried out deeply. The ditch should be in the north-south direction, so that the light is evenly received, and it can also reduce the lodging of green onions caused by strong winds in the north in autumn and winter. Trenching is about 0.33m deep and 0.75m wide. 3. Seedling emergence, seedling selection and grading: water the seedbed 1 day before seedling emergence, and shake the soil clean when seedling emergence. Selection and grading of seedlings. Remove diseased seedlings, residual seedlings and coated seedlings, and divide the seedlings into three grades: large, medium and small. Those that can't be planted that day should be placed in the shade with the roots facing down to prevent the seedlings from yellowing or rotting when heated. 4. Planting: the planting methods of green onions are the method of returning soil to soil; The method of inserting eyes and filling onions. Sow1-2kg carbofuran at the bottom of the ditch per mu, plant 15000-20000 plants per mu, and do not bury the core leaves at the depth of soil remediation. Ii. site management 1. Watering: The stage of delaying seedling growth in summer is the rainy season in hot summer, so it is necessary to pay attention to drainage after rain to prevent large-inch irrigation in onion ditch, which will lead to hypoxia and rot of root system. During this period, water is generally not watered, so that the roots can be quickly updated and the plants can turn green. At the beginning of August, the temperature is still high, the plant growth is still slow, the water demand is not high, and watering is less. In case of drought, water early in the morning to avoid watering at noon to suddenly reduce the ground temperature and affect root growth. After the intense heat and before the first frost, the green onions enter the peak growth period, with an average of 1 leaf every 7-8 days. The higher the leaf order, the larger the leaves, and the longer the life of each leaf. During this period, due to the rapid increase in the weight of leaves and onions, the water demand has also increased greatly. It should be combined with topdressing and soil cultivation, and water should be poured every 4-5 days 1 time, with a large amount of water, and water retaining ridges should be built in the onion ditch to make the water in each ditch fully uniform. If there is little rain and insufficient watering, it will seriously affect the growth rate and yield of onions. Generally, high-yield plots need to be watered 8- 10 times at this stage. After the first frost, the temperature dropped, and the green onions basically grew well, entering the stage of full false stems (onions). Plants grow slowly and need less water, so it is still necessary to keep the soil moist. Make the pseudostem-filled mesophyll thick, full of gum, fresh and plump. During this period, water should be irrigated more than twice to meet the growth needs. Water should be stopped 7- 10 days before harvesting to facilitate harvesting, storage and transportation. 2. Timely topdressing is an important measure to obtain high yield and high quality of Chinese onion. (1) Early growth stage of Welsh onion: In the first and middle of August, foliar fertilizer should be applied 1 time. Apply farmyard manure 1000- 1500 kg, diammonium phosphate 7- 10 kg per mu, evenly intertillage and hoe in the ditch. Then watering 1 time can promote the growth of green onions and meet the needs of leaf growth. (2) The peak growth period of Welsh onion: After the end of August, the yield of Welsh onion is the fastest. Onion plants grow rapidly, are white and thick, and need a lot of water and nutrients. At this time, it is necessary to topdressing, and pay equal attention to nitrogen, phosphorus and potassium for 2-3 times. For the first time, 4,000-5,000 kg of decomposed farmyard manure or 0/5-20 kg of potassium sulfate/kloc can be applied on both sides of onion rows, and then the soil is ridged and watered after intertillage. After the last two topdressing, it is feasible to sprinkle 15-20kg ternary compound fertilizer, and then water it after intertillage. 3. Soil cultivation: Welsh onion can increase the supply of fertilizer and water, and at the same time, cultivating soil can prolong the length of onion and improve the quality of onion. Through intertillage, the ridged soil is ploughed into onion ditch in stages. By the end of August and the beginning of September, the ditch was flat. In the future, we should plough the soil several times, turning the original ridge into a ditch and the onion ditch into a ridge. The height of each soil raising depends on the height of the pseudostem growth, about 3-4 cm. The soil should be cultivated to the junction of leaf sheath and leaf body, generally from beginning of autumn to harvest for 3-4 times.

How much gold can you produce by planting green onions on an acre of land?
1, my home is in Zhangqiu, the main producing area of green onions in Shandong, and now the price is about 6 cents a catty.
2. In the land where green onions have never been planted before, the yield is about 1000 kg. However, with the increase of planting times of scallion, the harmful bacteria in the field increased, and the yield decreased year by year, commonly known as continuous cropping (the same as planting watermelon), and the yield at this time was more than 4000 kilograms.
3. Investment in one mu of land: 200 yuan for planting onions+800 yuan for irrigating land with chemical fertilizers and pesticides+200 yuan for cultivated land = about 1.200 yuan.
Because it is the main producing area, there are dealers to receive the goods every year during the green onion harvest season. I wonder how old the landlord is. If the scale is large, you can find the corresponding dealer online to pull the goods in the past.
20 15 Are there many green onions planted in Shandong?
Sow and cultivate onion seedlings every autumn equinox, and plant them at the bottom of the ditch in May of the following year. With the growth of onion, cultivate the soil no higher than the bifurcation of onion leaves every time, and harvest onion at the end of 10. It is best to choose varieties with less tillering for onion seeds. There are three main types of Shandong Welsh onion, namely: (1) Landrace type: the pseudostem is tall, the aspect ratio is greater than 10, and the yield is high, but good cultivation conditions are needed. Its representative variety is Zhangqiu Welsh onion. Plant height is above 120 cm, and it does not tiller; Onion is about 60 cm long and 4 ~ 5 cm in transverse diameter; Rich texture, white, crisp, tender, less fiber, more juice, sweet and slightly spicy taste, good quality, suitable for raw and cooked food. Generally, the weight of a single plant is 300-500g, and the yield per mu is 4000-6000kg. (2) Short and white type: tubular leaves are closely arranged, leaves and pseudostems are relatively short, and the length-width ratio of pseudostems is less than 10, which is easy to cultivate. The representative variety is Shouguang Baye Banner. The plant height is about 100 cm, the pseudostem is 40 cm long, and eight leaves are left when harvesting, so it is called "eight-leaf combination". The weight per plant is 300-500g, and the yield per mu is more than 5000kg. (3) Drumstick type: the pseudostem is short, the base is enlarged, and it gradually becomes thinner and slightly curved upward, which looks like a drumstick, so it is called "drumstick onion". The requirements for culture conditions are not strict. The representative variety is guanxian chicken leg onion, thick and short, with a plant height of about 70 cm; The pseudostem is 25 ~ 30 cm long and the base is obviously enlarged. False stems are thin, dense, white, spicy and fragrant, which are most suitable for cooked food. The weight of a single plant is about 250 grams, and the yield per mu is 3500 ~ 4000 kilograms.

How much is the yield of green onions per mu in Henan?
If hard-core green onions are planted, the yield per mu is 8000- 10000 kg, and the length is more than 5000 kg. If the traditional annual onion (black onion) is planted in Henan, the yield is only half of that of hard-core onion. Onions are time-consuming and laborious, and they are divided into nests three times a year. It won't be harvested until the year before last. It tastes good. Nanyang locals don't eat hard-core onions all the year round. Hard-core onion is easy to manage and has high yield. The price is similar, hard core makes money. If the place is closed and there are no onions, digest it on the spot. If the locals don't eat, they will not sell well, and no one wants to be cheap. Gaby at this time is not as green as last year. If iron is exported, farmers in Nantun green onion planting base in Ying Zhuang Town, Wolong District, Nanyang City, Henan Province are both black onions and iron onions. Look, this year's situation is not very good. Farmers are busy for nothing again. It's good to get a good deal every five years.
