Green onions are a kind of vegetables that are good for fat. For a long time, many vegetable farmers are used to ditching for one-time topdressing of green onions, which is unscientific. Because this is not only easy to cut off the roots of the green onions, but also burns the young roots of the green onions due to excessive concentration of fertilization, leading to the occurrence of dry and dead leaves, affecting the quality of the green onions and reducing the yield. No. The correct method of fertilization should be: follow the principle of “eat less and eat more mealsâ€, adopt the method of soil fertility, from the planting of green onions to the harvesting points for 3 to 4 times to prevent de-fertilization in the late growth stage of green onions. Each time, apply 30 to 30 kilograms of compound fertilizer per mu, or 10 to 15 kilograms of urea and potassium sulfate. According to the growth period of green onion, the amount of fertilizer should be slightly more than the amount of fertilizer applied last time; Apply to the surface of the roots of the onion, then cover the soil with fertilizer, reduce the loss of fertilizer volatilization, promote the whitening softening and elongation, and enhance the wind resistance. After fertilizing, water should be poured once in two days to dissolve the fertilizer in the soil and rapidly decompose to promote the growth and development of the onion.
