Green onion planting is very common, how to cultivate soil for green onion planting?

Soil for green onions is for the growth and elongation of green onions, to create a dark suitable growth environment, through multiple soil, and the length of green onions can be extended one by one, and at the same time, through soil, but also to make the soil around the green onions loose and maintain well,The yield of green onions is high, generally about 8000-10000 catties per mu, and it is best to cultivate soil 3-4 times during the growth process. The first time is after transplanting, wait for the seedlings to recover and cultivate the soil slightly. The second and third times should be cultivated during the vigorous period of the onions.

Soil cultivation time. Green onions are generally cultivated 3 times during their lifetime. For the first time, it became a "small pei", the thickness of the soil is controlled at about 5 cm, and the soil can be cultivated when the green onion grows to 30 cm, not too early, otherwise it can cause the green onion to grow slowly and the green onion to bend; Green onion soil saving time and effort saving method:

For the first time, it became a "small pei", the thickness of the soil is controlled at about 5 cm, and the soil can be cultivated when the green onion grows to 30 cm, not too early, otherwise it can cause the green onion to grow slowly and the green onion to bend; Soil cultivation should be carried out in the afternoon.

Green onion is a kind of green onion, belongs to the lily family herbaceous plants, generally the upper part of the green onion leaves, the lower part of the white onion white, its taste is pungent and flat, with the effect of muscle sweating, swelling and detoxification, detoxification and seasoning, the most important use is to make condiments, is a daily kitchen must-have, to prevent lodging, but also to improve the yield and quality of green onions. However, these are not the key points in the growth process of how many times you need to cultivate soil, when to carry out soil cultivation, what are the precautions, this is the real point, so the following with these questions to answer one by one.

In the process of green onion planting, it is necessary to carry out soil cultivation, because soil cultivation is an important measure to soften the leaf sheath, prevent lodging, and improve the yield and quality of green onions. Reasonable soil cultivation of green onions can not only increase the length of green onions, prevent lodging and bending, but also greatly improve the taste and quality of green onions. For the first time, it became a "small pei", the thickness of the soil is controlled at about 5 cm, and the green onion grows to 30 cm after the green onion is formed, and the balanced type such as 15-15-15 type compound fertilizer 25 kg with 150 kg of organic fertilizer can be applied to promote the deep rooting and meet the needs of the early growth of green onions.

Green onion planting generally needs to be cultivated 3 times, the first "small cultivation", and the thickness of the soil is controlled at about 5 cm; The thickness of the second soil cultivation is about 10 cm, and the second soil cultivation should be carried out when the green onion grows to 40 to 45 cm; The third cultivation is about 20 days before harvest to improve the quality and taste.

The planting of green onions should bury the soil tighter, so that the heat preservation can be better and the roots of the green onions can germinate.

It is necessary to cultivate the soil in a timely manner, but also to cultivate the soil moderately, to ensure that the soil for green onion planting is firm, and the rhizome of the green onion can not be harmed when cultivating the soil.

First of all, the width of the soil must not exceed 1 3 of the row spacing. Moreover, ridge soil should be carried out on both sides, and it must be carried out in the afternoon when cultivating the soil, so as not to damage the leaves.

Generally, the green onion grows to about 30 cm to start the soil, to be reasonable top dressing, and not too wide, should be about 1 3 row spacing. Don't go too deep so as not to hurt the roots of the green onions.

Green onions should be planted in some places with fertile soil, and they should also be watered in time after planting.

1. Soil cultivation time.

Generally, the green onion grows to about 30 cm can be cultivated, not too early, otherwise it will cause the green onion to grow slowly and the green onion bends, the soil should be carried out in the afternoon, because the leaves are tender at this time, and the leaves will not be damaged, if you miss this opportunity, the green onion leaves will be damaged in the potting process.

2. Reasonable top dressing.

In the process of green onion growth, it is generally necessary to carry out about 3 times of soil, the first time is a small soil, the thickness of the soil is controlled at about 5 cm, generally after the green onion grows to 30 cm after the formation of green onion, 25 kg of compound fertilizer can be applied per mu with 150 kg of organic fertilizer, so as to promote the root system to take root and meet the needs of the early growth of green onions. When the green onion grows to 40-45 cm, the second soil cultivation is carried out, and the thickness of the soil is controlled at about 10 cm. The last time the soil is about 20 days before harvesting, in order to improve the quality and taste of the green onion, the thickness of the soil is controlled at about 10 cm.

3. Soil cultivation method.

The width of the soil should not be too wide, take the soil from the middle of the row, and the width of the soil should not exceed one-third of the row spacing, and not too deep, so as not to hurt the roots, and the soil should be pat solid to prevent the rain from collapsing. The soil is too dry or too wet and should not be cultivated, and the false stem of the green onion should be kept straight, so it is not suitable to cultivate the soil too deeply, and bury it deep to the leaf sheath, otherwise it is easy to cause the white onion to bend.

4. Pay attention to the season.

In the high temperature season, it is not advisable to cultivate soil, otherwise the false stem will rot because it is buried too deep in the soil, and the number of soil cultivation can not be too much, and frequent soil cultivation will not only increase the workload, but also inevitably hurt the roots and leaves, affecting the growth of straw. Do not be too deep at a time, otherwise it will bury the leaves, which is easy to cause decay, each time the thickness of the soil is 3-4 cm, the soil will be cultivated to the boundary between the leaf sheath and the leaf body, that is, only the leaf sheath will be buried, and the leaves will not be buried.

Green onion soil cultivation is an important measure to increase the length of green onions, prevent lodging, and improve the quality of green onions. The following issues should be paid attention to when soiling green onions:

Timely soil cultivation: In autumn, the temperature gradually cools, green onions begin to grow vigorously, the leaves continue to increase, and the leaf sheath continues to lengthen. The soil is cultivated too early, and the temperature is too high, which is easy to cause white rot of green onions; If the soil is cultivated late, the plant is prone to lodging.

Moderate soil cultivation: When cultivating soil, the soil is cultivated to the boundary between the leaf sheath and the leaf body, that is, only the leaf sheath is buried, and the leaf body is not buried, so as not to cause leaf rot.

Reasonable soil: take soil from the middle of the row, and the width of the soil should not exceed 1 3 of the row spacing, so as not to hurt the roots.

Soil should be solid: When cultivating soil, the soil on both shoulders of the ridge should be patted to avoid collapse caused by watering or rain washing.

Avoid hurting onions: Do not hurt false stems and leaves when cultivating soil, so as not to affect the photosynthesis of leaves.

Loosen first and then cultivate: Before soil cultivation, the soil should be loosened by cultivating, and then the soil should be cultivated.

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.

The correct planting method for planting green onions is as follows:

1.Planting green onions should first choose a good planting site, the land should be relatively flat and fertile, although it is very adaptable, but do not choose a cold and damp place, you should choose a sunny, close to the water source and drainage is more convenient plot.

2.To plant green onions, you can use seeds, or you can use seedlings. When planting, choose the best seeds and spread a layer of soil on top so that the seeds can germinate quickly.

3.Green onion is a variety that is resistant to low and high temperatures. Although temperature has little effect on the growth of green onions, the appropriate temperature is beneficial to the quality and yield of green onions.

4.There are appropriate requirements for the light intensity of green onions. Because the tubular leaves of green onions can still get better light in the case of intensive planting, there is no need for strong light irradiation.

Green onion is a kind of green onion, green onion production area in northern China more seedling transplanting, the main production area in the middle and lower reaches of the Yellow River is mostly sown in autumn, but it is necessary to strictly control the seedlings before winter no more than 3 leaves, the south of the Yellow River is mostly spring sowing, and the local temperature reaches 7 when it should be sown quickly.

1. The time of planting onions is generally selected around May to July every year, and the climate of this time period is more suitable, which can be conducive to survival after planting onions, and can also promote the growth and development in the later stage.

2. Land preparation and fertilization: Before planting onions, land preparation and fertilization should be carried out to ensure the basic conditions for planting. Choose a place with flat terrain, smooth drainage, loose and fertile, and sunny places, pick up the stones in the soil in advance, and then remove the weeds, and dry the soil and plough it.

In order to increase nutrients, you can apply well-rotted organic fertilizer to the soil to improve the fertility of the soil.

3. Select onion seedlings: green onion seedlings can be obtained by sowing seedlings, or you can directly dig Youchang to buy cultivated green onion seedlings, which requires good growth and vigorous growth, in order to minimize the impact of the disease, the disinfection and sterilization solution should be prepared in advance, and the green onion seedlings should be soaked in it for disinfection and sterilization, and then placed next to dry.

4. Planting: Smooth the soil, dig out the orange gully, plant the green onion seedlings straight into the gully, cover the soil compact, and then water it thoroughly.

5. Later management: After this watering, do not repeat watering in the short term, keep the soil dry, wait until the leaf stage is properly watered, and water in time during the vigorous growth period. After the planting growth is stable, top dressing should be carried out three times a year to ensure good nutrient supply.

Green onions are prone to pests and diseases, so we must pay attention to prevention and control.
