Green onion planting method, green onion planting method

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.

Choose the soil: Choose the soil with abundant sunlight and rich organic matter for planting green onions. Sowing seedlings:

Sow the seeds, cover with soil and cover with mulch. Seedling transplanting: After the seedlings are stretched, they are transplanted according to the row spacing of 90 cm and the plant spacing of 3 cm.

Water and fertilizer management: fertilize once with compound fertilizer after planting, and water in time.

1. Select the soil

Green onions are best planted in the soil with abundant light, convenient drainage and irrigation, deep soil layer and rich organic matter, deep ploughing of the soil for more than 30 cm, breaking the compacted soil blocks, making the soil loose, conducive to the growth of the root system, exposing the soil to the sun after ploughing, and applying well-rotted organic fertilizer.

2. Sow seeds and raise seedlings

Choose high-quality green onion seeds with strong disease resistance and high yield, water enough water before sowing to keep the soil moist, sow evenly by sowing, cover the surface with a layer of dry river sand or fine soil, and cover it with transparent plastic film before emergence, which has the effect of heat preservation and moisturizing, and can also prevent soil compaction due to excessive rainwater.

3. Transplanting seedlings

Green onions can emerge about 8-10 days after sowing, remove the mulch film and water once, seedlings stretch according to the row spacing of 90 cm, 2-3 cm of plant spacing transplanting and planting, according to the size of the seedlings evenly distributed, dig 15-20 cm deep planting ditch, apply pesticides to control pests and diseases.

4. Water and fertilizer management

Green onions have certain requirements for fertilizer during the growth period, nitrogen, potassium compound fertilizer when fertilizing, top dressing once after planting, the time of fertilization in the later stage is mainly determined according to the stubble, combined with soil watering 20 kg of fertilizer per mu, watering in time after fertilization, so as not to overly concentrate fertilizer and produce fertilizer damage.

<> planting of green onions is generally carried out in spring and autumn, and the survival rate of planting will be relatively high at this time. The soil for planting needs to be loose, breathable, deep and well-drained. When planting green onions, there should be a certain distance between them, keep the soil moist after planting, and apply thin fertilizer frequently during the vigorous growth period.

1. Planting time.

Planting green onions is generally carried out in spring and autumn, the weather is warmer at this time, the temperature is about 20, the most suitable for the growth and development of green onions, the survival rate of green onions will be relatively high after planting, and it can also grow relatively fast, and it is best to choose in sunny weather when planting.

2. Suitable soil.

Green onions are suitable for growing in loose and breathable, deep soil and well-drained soil, if the soil is too sticky, the roots of green onions can not grow, resulting in poor growth of green onions. Before planting, you can mix some organic fertilizer into the soil, so that the fertility of the soil will be more sufficient, 3. Planting and maintenance.

When planting green onions into the soil, there should be a certain distance interval, not too dense, otherwise it is not conducive to the growth of green onions, and it is necessary to water immediately after planting to keep the soil moist, and when the green onions are growing vigorously, you can apply phosphorus, potassium and nitrogen compound fertilizer every half a month to help it grow.

The summer-sown green onions are planted in early to mid-September, and the autumn-sown green onions are planted in March and April of the following year.

1. Seedling. The amount of green onion per mu is 2-4 kg, which can be soaked and germinated before sowing, and covered with soil about 2 cm after sowing.

2. Medium colonization.

The planting period depends on the variety and local climate, and can be rotated with crops such as wheat, barley, and spring cabbage.

3. Field management.

1) Watering and cultivating.

The weather is not very dry, generally not suitable for watering, should strengthen the cultivation and weeding, loosen the topsoil, store water and moisture, and promote the development of root system. Heavy rain drains the water to prevent rotten roots, yellow leaves and dead seedlings.

2) Top dressing. Generally, it starts after the beginning of autumn and is carried out in combination with irrigation and hydroponics.

Green onion is a type of green onion, which can be divided into four types: ordinary green onion, divided green onion, green onion and floor onion. The green onion has a pungent taste, slightly warm in nature, and has the effect of publishing Tongyang, detoxifying and flavoring, sweating, antibacterial and vasodilation.

It is mainly used for symptoms such as wind chill and cold, chill and fever, headache and nasal congestion, cold and abdominal pain, dysentery and diarrhea, internal obstruction of insect accumulation, milk blockage, and unfavorable stool.

Green onions contain volatile oil, the main component of the oil is allicin, and it also contains diene inner sulfide and calcium oxalate. In addition, it contains fat, sugar, carotene, vitamin B, vitamin C, niacin, calcium, magnesium, iron and other ingredients.

It is a perennial herbaceous plant with cylindrical leaves, hollow in the middle, fragile and easy to break, and is blue. In East Asian countries and various Chinese areas, green onions are often eaten as a very common spice condiment or vegetable, and play an important role in oriental cuisine. In Shandong, there is a method of eating green onion dipping sauce.

How to grow green onions:

1. Planting time.

Green onions can be planted in March in spring, May in summer, and October in autumn every year, but the temperature is high in summer, the growth of green onions is slower, and the quality is poor, so it is best to plant in spring and autumn, and choose sunny, cloudy weather to make the plant grow better.

2. Soil preparation and fertilization.

Green onions are suitable for growing in loose and breathable soil, before planting, use a hoe to loosen the soil, and expose to the sun to dry for three days, wait for the soil to whiten, and then mix the rotted liquid fertilizer to improve the fertilizer content of the soil, and provide a fertile growth environment for green onions.

3. Planting.

When planting green onions, dig a shallow trench in the field with a distance of 20 centimeters, and then put the green onion seeds into it with the tip facing up, and control the spacing to about 8 centimeters. After planting, spray water for the green onions once a day to keep the soil moist and let the green onion seeds sprout and grow as soon as possible.

4. Ditch onion. 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.

5. 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.
