The high yield of green onions is very important, what are the high yield cultivation technologies o

The characteristics of green onions are that green onions have wide adaptability to temperature, green onion seedlings can overwinter, and they will not be dormant in hot summer, green onions can be harvested and sold at any time regardless of size, and growers can plant green onions all year round. Plots where green onions are planted should be made of clayey soil or clay soil rich in organic matter. Because the green onion is planted in the soil, the green onion is white and yellowish-white, and the texture is soft and the quality is poor; Although the green onion is white and hard, the yield is low and the quality is poor.

Easy to irrigate and drain. 2 row spacing - generally 75 cm or 80 cm, the depth of the ditch (flat) is not less than 20 cm to the soil (conducive to soil cultivation, increase the length of green onions). 3. After planting, sprinkle pesticides to prevent underground pests and gradually cultivate the soil, not higher than the branch on the green onion.

4. Management of pdyceps control. Green onion is also a relatively common vegetable in China, and it has a high status in the vegetable industry. Let's put it this way, the cultivated area of green onions accounts for 10% of the total area of vegetables, and the production accounts for 7% of the total production.

Well, such an important vegetable, it should not be a problem in terms of cultivation technology, <>

First of all, the ground is tidied up, and then the green onion seedlings are separated according to the size, the large green onion seedlings are planted, and the small ones are planted again. When planting onions, dig the ditch first, and then sprinkle some fertilizer into the ditch (appropriate amount) If there is wheat bran, it is best to sprinkle some wheat bran, green onions, there are sales in the market all year round, in our northeast, the planting area of green onions is more extensive, especially in winter, people have the habit of storing vegetables in winter, green onions are one of the indispensable ones, only winter storage, the number is very amazing.

After the white dew in autumn, plant green onion seeds, must be after white dew, if the white dew is planted before, the green onion will grow green buds in the second year, and the green onion heart will easily become a straight child, and it will soon become old. When planting onion seeds, first planing the soil in the vegetable furrow, and then using special tools to pull the ditch, soil cultivation is an important management measure when planting green onions, it has an important role in preventing lodging, softening false stems, and improving the quality and yield of green onions. Generally, the soil cultivation is carried out many times, starting from the height of the green onion 20 cm, once every half month.

First of all, it is necessary to choose high-quality varieties, and in the process of raising seedlings, it is necessary to choose the right sowing time, which is to strengthen management, and also to choose the soil with relatively high terrain and good drainage, and then we must loosen the soil in time, and there is to mix fertilizer and water in time.

First of all, when planting, we must choose the soil is more fertile and wide land, and use farmhouse fertilizer, do not use fertilizer bought outside, water the plants more, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time.

Sowing time: In order to increase the yield of green onions in the later stage, it is best to choose autumn sowing, the climate is different in the north and south, and the sowing time is best to determine the size of the seedlings before wintering, and the best is to grow to two leaves and one heart. Finishing the seedbed:

Choose a flat, fertile, water-rich plot of land for shallow tillage and fine raking, and then apply sufficient basal fertilizer, in the middle of the 20-25 meters long, 1 meter wide furrow. Sowing: Before sowing, pour enough water in the furrow, wait for the water to penetrate into the soil, stir the seeds with the sandy soil, and sprinkle evenly in the furrow twice.

First of all, it is necessary to choose high-quality green onion seeds and moist and evacuated soil, which is conducive to the high yield of green onions, and usually pay attention to watering and fertilizing green onions.

When planting seedlings, on the one hand, it is necessary to make a custom cave for planting green onions, so that the seedlings can be kept upright and planted, and cannot be planted obliquely. In the growth period of green onions, it is necessary to supplement fertilizer and water in time to provide nutrients needed for growth, and also supplement nitrogen, phosphorus, potassium, calcium and other elements, combined with soil for top dressing, to achieve the effect of promoting roots, strengthening fruits, increasing yield, and reducing the appearance of dead plants.

1. Apply enough fertilizer, fertilizer directly determines the growth of green onion plants, especially in the long term of green onion white wang, if the fertilizer is not enough, it will cause the green onion white short, coarse hardness is not enough, low yield, poor quality and other conditions. Fertilization should be based on decomposed organic fertilizer, supplemented by chemical fertilizer, rational use of nitrogen fertilizer, increase phosphorus and potassium fertilizer. On the basis of applying sufficient basal fertilizer, top dressing should be carried out in time.

2. Reasonable watering, the watering of green onions should be carried out according to the weather conditions and the dry and wet conditions of the soil. In late summer and early autumn, it is necessary to carry out a watering, which is mainly to promote the root development of green onions, but if the weather is very dry, it is necessary to minimize the amount of watering, and do a good job of drainage and drainage after the rainy season to prevent green onions from rooting, rotten roots, dead seedlings, etc.

1. Reasonable planting. The method of growing green onions is the key to determining the erection of the white onion and the white length of the green onion. On the one hand, when sowing seedlings, it is necessary to first set up a customized planting hole green onion so that the seedlings can be planted upright without being tilted.

On the other hand, please note that green onions are suitable for loam soils with a pH value. Cultivating and sowing green onions requires fertile land and adequate soil moisture. Seedlings will emerge about 7 days after green onion planting.

However, due to the high summer temperature and the high amount of rainfall in the summer, it is necessary to take good care of the prevention of waterlogging. At the same time, it is necessary to cultivate in time after rainfall to prevent the land from being compacted.

2. Apply enough fertilizer. Fertilizer directly determines the growth of green onion plants, especially during the flowering period of green onions. If the fertilizer is insufficient, it will lead to insufficient whiteness and roughness of the green onion.

Low yield, poor quality, etc. Fertilization should be based on decomposed organic fertilizers, supplemented by chemical fertilizers, rational application of nitrogen fertilizers, and increase the amount of phosphorus and potassium fertilizers. On the basis of the application of sufficient basal fertilizer, top dressing should be carried out in a timely manner.

3. Reasonable watering, green onions should be watered according to weather conditions and the dry and wet conditions of the soil. At the end of summer and the end of early fall, it should be watered once. Watering at this time is mainly to promote the root development of green onions, but if the weather is very dry, you should try to reduce the amount of watering and do a good job of draining after the rainy season.

Drain the waterlogging to prevent the green onions from shedding the roots, rotten roots, and dead seedlings.

The first thing to do is to choose a good variety. Seedlings are then raised in the right weather. After the green onion is planted, we must do a good job of drainage, and then strengthen the management of green onions at ordinary times, water more water on green onions, give it more top dressing, and then give the green onions soil, and we must pay attention not to bury the heart leaves when cultivating the soil.

It is best to sow seeds in autumn, the temperature is not too high, generally about 17 degrees on it, to choose some permeability and water absorption of good soil, you can prepare some compound fertilizer, fertilizer, nitrogen fertilizer, the distance of planting green onions is not too close, after the green onions are lived, they should be watered frequently, and they should also be properly cultivated, so that the quality of green onions planted is very good.

The planting time is generally from late May to early June. Before planting, the size of the seedlings is separated, and the diseased seedlings, weak seedlings, too small seedlings and obviously bent seedlings are removed, the plant spacing is 35-40 plants per meter, the row spacing is 1 meter, and about 10,000 plants are planted per mu. When planting, avoid breaking the green onion seedlings, the planting depth should not bury the green onion heart, too deep should not sprout, too shallow to affect the length of the green onion.

When planting, the leaf surface and the planting furrow should be arranged in a vertical direction, which is conducive to dense planting and management. Planting tools can be used about centimeters in diameter of the garden iron skewer or garden wood pole, planting first make a shallow hole, perpendicular to the ground, and then insert the seedlings, and then slightly lift up, so that the roots are spread downward, keep the green onion seedlings straight. If it is bent, the stem is bent until it is harvested later, and it becomes a defective product.

The white plant height of the long shallot, the uniform length and thickness of the white onion, and the high yield, the short green onion white onion white white is short and thick, in contrast, in the same area, the long green onion white variety has a higher yield than the short green onion white variety. According to the local planting habits and planting season (mostly spring and autumn), you can choose heat-resistant or cold-tolerant disease-resistant varieties. That is, the root of the green onion is long and thick is the most fundamental, if you want to make the root of the green onion long and thick, you have to give the green onion a long and thick growth environment, that is, to turn the land deeply, so that the land is soft, the green onion can grow long and thick, deep over the land, <>

Choose soil with loose soil, fertile soil and good drainage, and cannot rotate with onions, garlic and other crops to avoid yield reduction. It can be planted in fields where corn, sweet potatoes, soybeans and other fields have been planted. The choice of land, land preparation for furrowing, generally formed wide rice, the reason is that many green onion growers are only partial to the yield of green onions, the quality of green onions does not pay much attention to the final income, the green onion market has never lacked supply and demand of green onions, and some high-quality such as green onion white length, thickness, good taste of green onions ** has been firm.

Green onions can be planted at least twice a year. For the first time, you can choose to raise seedlings in June-July, plant them around September, and go on the market in March-April of the following year. The second time you can choose to raise seedlings in September, plant them in March-April, and market them in July-August.

Note that in the planting process, it must be reasonably densely planted, and deeply planted and covered. Generally, the green onions planted in our own vegetable gardens in our rural areas are first raised and then transplanted and planted. Green onion seeds should be sprouted.

You can soak the seeds with more than 50 warm water for half an hour, and stir when soaking the seeds, so that the seeds are fully absorbed by the water.

Choose the right land and grow good food. Because green onions are afraid of waterlogging and drought, it is necessary to choose a plot with good drainage, so it is recommended to choose loose sandy loam soil with high terrain and deep soil layer, and it is best to have not planted onions and garlic before. If it is the kind of land that has been planted for several years, it will almost be lost.

It should be watered and fertilized in a timely manner, and at the same time, it should also do a good job in the management of water and fertilizer, and it should also ensure sufficient light and suitable temperature, and it should also be sprayed in time to do a good job of pest control.

First of all, we should choose moist and fertile soil, and we should also choose high-yielding, pest-resistant seeds, and secondly, when planting, we should disinfect the land, and we should also pay attention to fertilization and watering, and pay attention to the prevention and control of pests and diseases, so that green onions can be highly productive.

Try to choose sandy loam soils. The quality of this soil is very good, so the green onions can get a good yield and the quality is quite high.

Soil preparation and fertilization: Choose a fertile, loose plot and apply high-quality farm fertilizer for mixing. Sowing seedlings:

Sprinkle the green onion seeds directly into the soil and water them. Start transplanting: When the emergence rate reaches 80%, transplant the seedlings into an open plot.

Fertilizer and water management: apply 1-2 times of fast-acting compound fertilizer throughout the seedling stage.

1. Soil preparation and fertilization

Green onions require a deep, loose and fertile sandy loam soil, deep ploughing of the land, 4000 kg of high-quality farmhouse fertilizer per mu as base fertilizer, mixed with the soil, made into a 2-meter-wide furrow, rake the flat furrow surface, ditch in the furrow, and the ditch is 6-7 cm deep.

2. Sow seeds and raise seedlings

The seeds of green onions are small, the seed coat is thick, the cotyledons are unearthed, the seedlings grow slowly, and the seedling period is long.

3. Start transplanting

When the emergence rate of green onions reaches 80%, it can be transplanted, remove the weak seedlings, and then take out the healthy seedlings, shake off the soil at the roots, and finally plant according to the spacing of 20-25 cm to ensure sufficient growth space.

4. Fertilizer and water management

After the green onion seedlings stretch their waist, they can be watered 1 time, so that the cotyledons stretch, take root and stabilize the seedlings, and then water 1-2 times according to the ground moisture, and then water 1-2 times, the water can not be too much, so as not to grow seedlings, the whole seedling period topdressing 1-2 times, mainly with fast-acting compound fertilizer, to promote the healthy growth of seedlings.

The seedlings should be pre-seeded and then planted in the land, and they should be watered a lot every day to ensure that the green onions grow very well.

Selection of good seeds: there are many varieties of green onions, and green onions are very usable to the environment, basically any seed can grow in any place, but it is related to its yield and quality, so before planting we have to choose varieties suitable for the local climate planting, you can first do a survey on the local green onion planting, choose high-quality and high-yield and the market is not bad varieties for planting, and then you can plant multiple varieties in time, check the economic benefits of planting, and then select the best.

When planting green onions, be sure to add some fertilizer to the soil so that the green onions can grow thick and strong, and they should be watered properly.

Shallots are cold-tolerant, fertilizer-tolerant, and widely adaptable to soil, but have weak heat and drought resistance. The vegetative growth period is suitable for cool climatic conditions, the germination temperature is 13 20, the stem and leaf growth temperature is 18 23, the root growth temperature is 14 18, the shallots are mainly edible young leaves and green onion white, which is rich in nutrition and can be fishy and seasoned. Not only that, but it also has the effect of strengthening the stomach and sweating.

Shallots have strong adaptability, short growth cycle, and strong tillering ability, so they can be tillered and transplanted many times.

The seeds of shallots are flattened, the size of sorghum grains, before sowing, it is best to screen the shallot seeds, remove the impurities inside, screen out the seeds that are more deflated, and the seeds with damage on the surface, and leave the good seeds for sowing, the best choice of fertile and loose drainage soil with strong drainage layer of deep soil is the best, generally choose humus soil, rotten leaf soil, forest soil, fine sand according to 3:1:1:

1 ratio, then add an appropriate amount of fertilizer solution.

Due to the shallow distribution of onion roots, the absorption is weak, so it is not tolerant to thick fertilizer, not tolerant to drought and waterlogging, and the competitiveness of weeds is poor. For the planting of shallots, proper watering can be, the amount of watering should not be too large or the phenomenon of water accumulation, because more water will cause the root rot of shallots, so according to the characteristics of shallots drought tolerance and waterlogging tolerance, proper watering can be, after sowing the seeds of shallots, you need to water a small amount every 2 3 days, apply organic fertilizer every 15 20 days, you can also apply rotting thin manure water, give it plenty of sunlight, and regularly deal with the surrounding weeds, so as to make the shallot grow better.

After returning to green, weeds should be pulled out in time for secondary seedling. About 7 days before planting, stop watering and return to refining seedlings to improve the survival rate of planting. Before planting, the seedlings are 40 cm to 50 cm high, the stem thickness is 1 cm cm, and the root system is developed.
