How to grow green onions How to grow green onions

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 selection of good varieties: 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 must 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 also good varieties for planting, and then you can plant multiple varieties in time to view the economic benefits of planting, Then select the best of the best.

2. Land preparation and fertilization: green onions do not have high requirements for planting land, generally as long as the light is more sufficient, and close to the water source, convenient for watering, the soil organic matter content is rich in plots can be planted. When preparing the land, it is necessary to turn the first grandson at least 30 centimeters deeper, and clean up the impurities in the soil, pest residues, weed roots, etc., so that the later management will be relatively simple.

Finally, the clods of soil are broken as much as possible, and then raked flat, and at the same time, the width is about one meter to one meter and five meters to make a ditch for planting.

3. Scientific planting: there are three main ways of green onion planting, namely seed chain plant propagation, branch propagation and bulb propagation, the suitable planting time is generally around May to June each year, and then according to the interval of 30 centimeters per row of ditching for strip sowing or strip planting, the interval of each plant is about five to eight centimeters, and the planting site must be watered thoroughly before planting, so that the survival rate can be increased by at least 15 percent.

4. Fertilization technology: the main right or wrong of green onions still needs to be decided according to the fertility of the planting place and the growth of green onions, generally after the beginning of autumn for the first time fertilization, according to the normal fertilization situation per mu about 2,000 kilograms of soil miscellaneous fertilizer, or the use of 200 kilograms of cake fertilizer, plus 20 kilograms of urea. After the summer heat, the second top dressing is carried out, and about 15 kilograms of urea are needed for this fertilization.

Finally, it is to look at the growth of green onions, if the branches and leaves of green onions are relatively thin, and they are more mixed with inverted hooks, then we also need to apply an appropriate amount of potassium fertilizer. And add an appropriate amount of fertilizer to each growth of green onions, and supplement the nutrients required for the growth of green onions.

5. Field management: There will be no seedlings in about five or six days after planting, but the temperature in summer is relatively high, and the rainfall is relatively large, so we must be prepared for waterlogging and drainage, and at the same time, we should carry out cultivation in time after the rain, so as to avoid the soil celery and compaction. The root system of green onions is relatively weak, so the planting ground should be maintained at least more than 75 percent, and there is basically no need for too much watering when the weather is not particularly dry, only need to strengthen the management of soil permeability in the field and weeding.

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: onion seedlings can be obtained by sowing seedlings, or you can directly buy cultivated onion seedlings, which require good growth and vigorous growth, in order to minimize the impact of the disease, you should prepare a disinfection and sterilization solution in advance, soak the green onion seedlings into it for disinfection and sterilization, and then put it next to dry.

4. Planting: level the soil, dig out the ravine, plant the green onion seedlings straight into the ravine, cover the soil and compaction it, 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.

Cultivation of green onions:

1. Green onion seedlings.

In the prepared soil, open a small soil ditch with a depth of about 2 cm, and then the spacing between each ditch is about 5 cm, and then sprinkle the seeds of green onions into the small ditch, and the density of sowing is 1 cm 3 seeds, and then cover it with soil. After it is done, it is time to water, and the first time it must be watered thoroughly, and the sowing work is basically done.

2. Seedling management.

The management of green onion seedlings is very simple, only daily watering is required, and the weather is getting colder day by day, when the green onion grows to a height of about seven or eight centimeters, the aboveground part gradually withers and begins to dormant. No management is required throughout the winter.

Until the spring of the next year, the green onion seedlings will begin to turn green, so it is necessary to water the green water in time and top dressing. When the green onion seedlings grow to more than twenty or thirty centimeters, you can start transplanting the green onions.

3. Ditch shallots. Open the ditch about 30 cm, and then the spacing between each ditch is about 50 cm, and then apply enough bottom fertilizer at the bottom of the ditch to ensure that the green onion seedlings can have sufficient nutrients after transplanting.

4. Water and fertilizer management.

After that, the green onion began to continue to grow to a high place, the main management is to cultivate the soil, the soil and watering should be carried out with each other, the soil becomes semi-dry after watering, and the soil becomes dry after the soil is watered, so that with continuous watering and soil, the green onion will grow higher and higher, and the part buried in the soil is the green onion white, and the green onion can be harvested when the green onion is high enough, and the soil is high enough.

5. Harvesting. When harvesting, we should try to stay away from the root of the green onion to avoid digging the green onion, and the harvested green onion should be slightly dried to remove the moisture, so that it can be stored for a longer time.
