How to fertilize green onions?

How to fertilize green onions? Please introduce thank you very much for a long time, many vegetable farmers are accustomed to trenching for green onions one-time topdressing, which is unscientific. Because, this is not only easy to cut off the roots of green onions, but also burn out the tender fibrous roots of green onions due to excessive concentration of fertilization, resulting in the occurrence of dry tips and withered leaves, affecting the quality of green onions and reducing yield. After the production practice in the past two years, I concluded that the scientific fertilization method should follow the principle of "eat less and eat more", from planting to harvest and topdressing for 3 to 4 times, so as to prevent the fattening of green onions in the later growth stage. Each time the fertilizer should be spread evenly on the surface of the green onion root, and then the soil should be fertilized to reduce the volatilization loss of the fertilizer, promote the onion softening and elongation, and enhance the wind resistance. After fertilizing, it is necessary to water once within two days to make the fertilizer dissolve in the soil and decompose quickly, so as to promote the healthy growth and development of green onions.
