Leeks are rich in iron, calcium, and vitamin K, and they are the protagonists on diet tables. They are popular vegetables. The use of winter greenhouses to plant winter leeks, the Spring Festival can be listed, the harvest period of up to 4? 5 months, the yield per mu up to 3,000 kilograms or more. Now introduce its cultivation methods are as follows: Choose good breeds. Choose color tadpoles with good palatability, high yield, strong resistance and cold resistance, such as dahongpao of red leaf garden type and full leaf red. Soil fertigation. We choose land plots with flat terrain, fertile soil, convenient irrigation and irrigation, and low weeds. We will plow 15-20 centimeters deep in November, apply 3,000 kilograms of high-quality organic manure per acre and 25 kilograms of diammonium phosphate as base fertilizer. Afterwards, we will make a width of 1 to 1.2 meters in the flat, and we will make the surface fine and smooth and make it empty. Timely sowing. You can sow in the middle or late November. Before sowing, we should use enough water to plant 3-4 kg per acre. Mix the seed with appropriate amount of fine sand and spread it onto the surface of the noodles. Put on the foot or cover with a layer of dirt and then cover the film. Afterwards, a small shed with a height of 70-80 cm high was supported by a bamboo bar 2 meters long and covered with a film. Strengthen management. On the basis of pouring water, watering is not required before emergence, and emergence can occur in 5-7 days. After the cotyledon was unearthed, the mulching film was removed for the first time weeding the seedlings. When the two true leaves are grown, the second time weeding and seedlings are carried out, and the first time the fertilizer is poured for the first time, usually 10 kg of nitrogen-phosphorus compound fertilizer is topped off, and the second fertilizer is applied every 15 days and then watered. Mushi compound fertilizer 5 kilograms, after each harvest 1, top dressing watered once, each time fertilization 5-10 kilograms per mu or application of manure fecal urine fertilizer 1000 kilograms. At the end of March of the following year, when the temperature rises, small arch sheds can be removed, ventilation can be enhanced, and high-temperature burning of seedlings and white rust of leek can be prevented. Harvest timely. Leek grows to 4-6 leaves, plant height 10-15 cm can be listed between large seedlings, while replanting leeks, so that can be harvested in batches until the first half of June Qingdai. Pay attention to the fact that every time you receive income, you need to keep a small amount of time, keep the seedlings evenly, and increase the output.
