Planting techniques of Welsh Onion High yield cultivation techniques of Welsh Onion

Green onions, I believe we all know very well, because life often eat a kind of vegetable. Green onions are more fragrant vegetables, because of their special spicy smell, they are often used for seasoning or deodorization. Green onion is easy to grow and is a very good vegetable to grow. Let's go with Xiaobian to learn about the planting method of green onion.

Planting technique of Welsh Onion

1. Nursery land selection. Green onion is a vegetable that forbids continuous cropping, and continuous cropping is also avoided in seedling land. The nursery land should choose the high pit land of the previous non-onion and garlic crops. Do not choose barren grass, otherwise the seedling land is overgrown with weeds. Special personnel should be responsible for raising seedlings.

2. After the harvest of the previous crop, turn deep into the sun twice and relax for 20 days. The seedling period of green onion is as long as 50 days, so the seedling field should apply 1000 kilograms of mature fertilizer per mu. The width of the bed is 1.5 meters with a trench, forming a small flat bed with a net width of 1.1 meters. Fine ground preparation. Make a good ditch around.

3, export green onions, the varieties are generally designated by foreign businessmen, mainly: Changbao, Changyue, Mingyan, Jinchang No. 3 and so on. For every 100 grams of seeds, a seedling bed of 35 square meters is required, and the seedlings raised in this way can be transplanted to 1 mu of field. Generally use sowing, sowing should be very uniform. The regular sowing date is early April.

4. After sowing, water should be watered (insecticide is added to the water) to reach 60% of the soil moisture. Do not water the seedlings before emergence. After watering, the fine dry soil is 0.5 cm thick, and the soil can not be watered to prevent soil consolidation. Plastic film can be covered before seedling emergence after sowing, which is beneficial to warming, moisturizing and preventing soil consolidation caused by Rain Water. But to prevent the harm of high temperature.

5. The germination temperature of Welsh onion seeds is the fastest at about 18 ℃. Seedlings can emerge 6 days after sowing. 60% uncover the plastic film in time after emergence, the film is too late, and the seedling is thin and weak. After the plastic film is removed, in order to prevent the erosion of the heavy rain, it is necessary to set up a small ring shed, cover the film on the small ring shed before the rain, and uncover the film after the rain, especially within half a month after the seedling is set up, otherwise a large number of seedlings will fall down due to cataplexy after the heavy rain.

High yield cultivation techniques of Welsh Onion

The main results are as follows: 1. the planting time is generally from late May to early June.

2. Before planting, the large and small seedlings were separated, and the diseased seedlings, weak seedlings, over-small seedlings and obviously curved seedlings were removed. The plant spacing was 40 plants per meter, the row spacing was 1 meter, and about 23000 seedlings were planted per mu. Avoid the breaking of green onion seedlings when planting, the planting depth is not to bury the green onion heart, too deep is not suitable for seedling, too shallow affects the length of green onion. When planting, the leaf surface and planting ditch should be arranged in a vertical direction, which is beneficial to close planting and management.

3. Planting tools can use iron cuttings or wood poles with a diameter of about 1.5 centimeters. When planting, make shallow holes first, perpendicular to the ground, then insert the seedlings, and then lift them up slightly to make the roots spread down and keep the onion seedlings straight. If the stem is bent until later harvested, it will become inferior.

4. The planting should be planted on the same side of the onion ditch, which is beneficial to drainage after rain.

5. After planting, the loose soil on both sides of the onion plant was compacted, and then watered thoroughly.

Planting conditions of scallions

1. Temperature: Welsh onion originates from semi-cold zone. In cold and warm climate, Welsh onion has high yield, good quality, strong cold tolerance, can endure low temperature of-20 ℃, seedlings can survive the winter safely under the condition of-10 ℃, and the highest can withstand high temperature of 45 ℃.

2. Illumination: green onions do not require high light intensity and neutral sunshine time. As long as they pass vernalization under the action of low temperature, they can bolt and blossom normally regardless of the duration of sunshine.

3. Moisture: the leaves of Welsh onions are tubular, waxy and drought resistant, which can reduce water evaporation and tolerate drought. The root system has no root hair, the water absorption capacity is poor, and each growth period must meet the water supply in order to grow healthily.

4. Soil: Welsh onion originally does not have strict requirements on soil, but the root group is small, without root hair, and the ability of absorbing fertilizer is poor. If you want to achieve high yield, you must choose the soil with loose soil, deep soil layer, fertile soil, good drainage and rich in organic matter.

Planting management of green onion

1, timely watering: transplanting is in the hot season, high temperature and rainy, generally do not water, rain and rain will lead to rotten roots and dead seedlings, we should pay attention to timely drainage. In case of high temperature and drought, it is necessary to water to cool down and promote growth.

2. Soil cultivation and fertilization: with the onion growing, the soil should be cultivated and fertilized in time, the final ridge height of the soil should be 70-80 cm, and the heart leaves should not be buried when cultivating the soil. Topdressing and soil cultivation are carried out at the same time, the first time should start from the Beginning of Autumn, 5000 kg of farm manure per mu, 10-15 kg of urea, and watering after application. The second topdressing the End of Heat was carried out, applying 15-20 kg urea per mu and 50 kg cake fertilizer. The third topdressing was in White Dew, when onion white entered the peak period of expansion, and fertilizer and water management was the key. 1000 kg of human feces and urine, 15 kg of urea, 50 kg of phosphate fertilizer and 5-10 kg of potash fertilizer could be applied along the ditch, and finally watered, and the fourth topdressing was carried out in the Autumn Equinox. 10-15 kg urea per mu, soil watering. White Dew should be sprayed with compound micro-fertilizer before and after, usually once every 5-7 days, 2-3 times in succession, the yield increase effect is obvious.

The above is the editor to summarize the green onion planting technology, I hope it can be helpful to everyone! In fact, green onions can also be planted at home, as long as a large pot can be planted! Those who often eat green onions at home might as well plant some at home and pick them when they want to eat them.
