The correct method of fertilization is: in accordance with the principle of “eat less and eat more mealsâ€, from the planting of green onions to harvesting 3-4 times, to prevent de-fertilization in the late growth stage of green onions. Every time the top dressing is applied, the fertilizer should be evenly spread on the surface of the root of the green onion, and then the soil is covered with fertilizer to reduce the volatilization loss of the fertilizer, 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 well and promote the healthy growth and development of the green onion.

Green onions should not be trenched and topdressed
For a long time, many vegetable farmers have been accustomed 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 green onions and reducing yield.
