How to manage the water and fertilizer of green onions? Please introduce that Welsh onion is a kind of vegetable that needs more fertilizer, which generally requires topdressing for 3 times from planting to harvest. For a long time, some onion farmers are used to trenching and manuring, so it is not only easy to cut off the roots of green onions, but also often burn out the young roots of green onions due to excessive concentration of fertilization, resulting in dry tips and withered leaves. According to the growth habit of Welsh onion fibrous root, which tends to fertilizer, water and temperature, the correct method of topdressing should be divided into three steps: spreading beside the root, cultivating soil pressure and watering. "Root side sprinkling" refers to the combination of weeding and loosening the soil between the ridges of green onions, and spreading fertilizer evenly on the surface of the roots of green onions. "soil pressure" means to cover the soil after spreading fertilizer in order to reduce the volatilization loss of fertilizer, promote the softening and elongation of onions, and enhance the ability of wind resistance.
