How to grow high quality green onions? 1, variety There are many types of green onions. In the process of selecting the species, it is necessary to be optimistic about the current season, temperature, environmental requirements, and planting varieties with high survival rates. 2, soil The green onion has very high requirements on the soil. It needs to survive in the soil with soft and fertile soil. The soil should not agglomerate and the onion growth will not be smooth. Before planting the green onions, it is necessary to ensure sufficient fertilizer in the soil. The demand for water by the green onions is not much demand for nitrogen and potassium. In the later stage, a lot of phosphate fertilizer is needed. If it is lacking, the yield of green onions will be greatly reduced. It is also necessary to control the amount of water, not to irrigate too much water, leading to a madness. Do not water after planting, affecting the survival of green onions. 3, temperature The right temperature will give the green onion a high quality yield. The root hair of the green onion is very small. The water and nutrients in the soil are also very little. Most of the root hairs live on the surface, so the green onions like wet land without the need for accumulation. Too much water, and the amount of water managed depends on the survival rate of the green onions. 4, top dressing When the green onion enters the hairy stage, it is necessary to carry out the topdressing of urea. In the leafy period, the second urea and potassium fertilizer are placed. The third time of fertilization is carried out during the formation of the scallion. After the fertilizer is scattered on the surface, the green onion is cultivated once, in order to increase the wind resistance and cold resistance of the green onion. It helps the growth of green onions, and then a watering work is done to dissolve the fertilizer of the application, and the green onions absorb the nutrients and thrive.
