Wild onions are also called scallions, wild onions have white flowers, and the fruit is as big as the onion, and the taste is unique and deeply loved by people. Wild onion is a unique wild vegetable in China. It grows on hillsides and grassland at an altitude of 2000~4500 meters. It is an excellent vegetarian seasoning. Scallions like a cool climate, cold resistance, heat resistance is very strong, the light intensity requirements are not strict, but the sun intensity is too high, the sunshine time is too short will affect the growth of wild onions; wild onions need less water than green onions but not tolerant to drought, Choose a layer of deep, loose, fertile, organic-rich sandy soil. First, the cultivation season The open field is planted in spring and autumn, and the protected land can be planted all year round in summer, or covered with shade nets in summer. It is generally harvested 60 to 80 days after sowing, and can be harvested 30 days after transplanting. Second, cultivation techniques Fine land preparation Whether planting seedlings or transplanting plots, fine grounding and applying base fertilizer should be done. Before sowing, choose sandy loam with deep soil layer, fertile and loose soil, flat terrain, well irrigation and drainage, or humus-rich loam. The soil is too sticky and easy to form, and the soil layer is shallow, which will cause poor root growth, affecting commercial properties, and soil pH. Take 6~8 is appropriate. Not suitable for continuous cropping with onions and garlic. Immediately after the harvest of the former crop, the clear land is finely ground, and it is required to reach the level and the soil. And combined with 667 meters of arable land, the fully decomposed chicken manure 3000~4000 kg, 20 kilograms of diammonium phosphate is flattened and made into a 1.5-meter-wide, 8-10-meter-long raft. The summer and low-lying sorghum plots should be made of sorghum 15-20 cm above the ground and surrounded by drainage ditch. 2. Seed treatment Wild onions are generally sown with dry seeds, but seeds are soaked and disinfected before sowing, which can increase the germination rate and emergence rate, and the seedlings grow neatly and prevent diseases. The method is to first soak the seeds in cold water for 10 minutes, remove the sorghum seeds and impurities, and then put them in warm water of about 65 ° C, and keep stirring for 20 to 30 minutes; or soak in the 500 times potassium permanganate solution for 20~ After 30 minutes, rinse with water and sown after drying. 3. Sowing Adopting the method of broadcasting or spreading, the spacing of the strips is 10 cm and the thickness of the soil is 1.5~2 cm thick; for each 667 m2, the seeds are used for 2~4 kg, and the ground is planted in early August. Before sowing, the water is poured into the water to seep and smooth the surface, and the seeds are evenly spread on the surface of the fine soil 0.8 to 1 cm. In order to prevent underground pests from covering the soil, a layer of phoxim granules or other poison baits may be applied. 4. Transplanting and planting After sowing, 40~50 days can be transplanted. Each 8~10 plants has a hole, and the row spacing is 12~20cm. The hole distance is 8~10cm. It should be shallow and should not be deep 4-6cm. It can also be harvested directly after planting without transplanting. 5. Post-broadcast management After sowing, the onion can be emerged in 8~10 days. The soil can not be dried before and after emergence and transplanting. Seedlings 1~3 leaf stage and transplanting slow seedlings control watering, cultivating loose soil 1~2 times to promote root growth, usually watering once every 7~10 days to keep the soil moist, in order to facilitate emergence, when the seedlings stretch The water can be re-irrigated once, the cotyledons are straightened, the seedlings are firmly rooted, and the seedlings are planted to remove the deformed seedlings, and the dense seedlings are removed. Afterwards, the watering is timely according to the situation, and the water volume should not be excessive to prevent the seedlings from growing. Combined with watering 10~15 kg per 667 m2 of water, the seedlings grow robustly. If the seedlings are rooted, it is necessary to cover the dry fine soil in time. In order to keep the onion safe and winter, pour a cold water before freezing. In the cold year, cover the horse with a layer of horse dung or grass to facilitate safe wintering. And insert the hole of the small arch shed before the soil is frozen to prevent the soil from freezing and inconvenient operation. In summer, the temperature is high and the light is strong. 6. shed According to the growth and development characteristics of the shallots and the local environmental conditions and the time to market for the shallots, the small sheds are usually shackled before and after the spring. Before the shed, remove the weedy onion leaves and loose the topsoil. After the green onion is returned to the green, the water is applied for 10~15 kg per 667 m2 to promote the growth of the seedlings. After the temperature rises, the growth and development of the shallots can be used. And the soil picks the right amount of water and top dressing. The temperature and humidity after the shed should be controlled at 12~14°C during the daytime, preferably at 3~4°C for nighttime temperatures above 0°C, and 70% for the humidity in the shed. If the growth of onion seedlings is weak, it can be topdressed once every 15 days before harvesting, and about 10 kilograms per 667 m2. 7. Harvest 40 to 60 days after the shed, when the seedling height is 25~30 cm, it can be harvested according to market conditions. The harvest can be carried out in a small arch shed. The small onions are bundled into small bundles of 0.25~0.5 kg. After being preserved, they should be listed. When harvesting, be careful not to let the shallots lose water to prevent the onion leaves from wilting, and not to damage the onion leaves so as not to reduce the commercial value of the shallots. . Wild onions are rich in protein, sugar, vitamins, dietary fiber and trace elements, which are very beneficial to the human body. Farmers can try to grow for health.
