Green onion has the functions of preventing cancer, increasing appetite, relaxing blood vessels, lowering cholesterol and impotence and tonifying the yin. Therefore, it is popular among consumers. Therefore, the cultivation method of planting green onions is organized by the net. The following is a detailed list for netizens. How to fertilize green onions? First, the amount of fertilizer needed for green onions: Generally, green onions can reach 5000-6000 kg/mu under high-yield conditions. Therefore, the demand for nutrients of green onions is high. Under normal circumstances, for every 1000 kg of green onions, 2.7-3.3 kg of pure nitrogen and 0.5-0.6 kg of phosphorus pentoxide are required. Potassium oxide is 3.3-4.0 kg, and the absorption ratio of NPK is 1:0.4:1.3, which is very sensitive to potassium and nitrogen nutrition. Second, the principle of fertilization of green onions: If the planting of green onions is not applied or less potassium fertilizer is applied, there will be a significant decrease in soil available potassium content, and a serious imbalance of nitrogen, phosphorus and potassium ratios, resulting in increased onion pests and diseases, reduced yield, poor quality, and reduced economic benefits of planting green onions. Applying potassium fertilizer to green onions can promote the growth of green onions and improve their ability to resist pests and diseases. The green onion is deficient in potassium, and the growth is slow, the plants are short, the scallions are short, and the yield is low. Balanced fertilization with green onion has a very significant effect on increasing yield, and can increase vitamin C and soluble sugar content of onion, reduce the content of harmful substances such as nitrate, and improve the intrinsic and appearance quality of green onion. After years of experimentation, the yield of green onion increased by 22.3%~28.2%, vitamin C content increased by 7.20%-16.0%, soluble sugar content increased by 15.5% and 12.7%, nitrate content decreased by 22.6% and 26.5%; The income is 1690-2000 yuan, and the ratio of production and application of potassium fertilizer is as high as 72.42 and 40.67:1. The balanced fertilization technology of green onion with the application of potassium fertilizer is more than 35,000 mu, with an average yield increase of about 20%. Third, the green onion fertilization recommendations: Onion balanced fertilization technology is simple and easy to apply fertilizer: on the basis of applying organic fertilizer, medium fertility plot, suitable fertilization amount is 20~25 kg per mu, 6-8 kg of phosphorus pentoxide, 20~ 30 kg, equivalent to 40 to 55 kg of urea, ordinary calcium phosphate (effective phosphorus content of 12%) 50 ~ 65 kg, potassium chloride (effective potassium content of 60%) 35 ~ 50kg. For example, when the soil fertility of the green onion planting land is low and the organic fertilizer is lacking, higher fertilization amount can be considered; on the contrary, when the soil fertility is high and the soil fertility foundation is good, the fertilization amount can be appropriately reduced. Fourth, the fertilization method of green onions: 1. Before the green onion is planted, 20% of the nitrogen and potassium fertilizers and all the phosphate fertilizers are mixed and used as the base fertilizer to spread the whole layer and deep into the soil. 2. The remaining 80% of nitrogen and potassium fertilizers should be used for topdressing. They should be applied twice in mid-September and mid-to-late October.
