4. Tian Tuan management
When planting onions, the field management is very heavy. After this plant enters the peak season, the demand for fertilizer and water is relatively large. Fertilize twice or three times in the middle growth period, and water it in time after each fertilization. In addition, in the process of onion growth, it is necessary to constantly cultivate the soil. Only in this way can the onion yield be high and the onion white be particularly long.
5, pest control
During onion planting, attention should be paid to the prevention and control of pests and diseases. After the occurrence of high-risk diseases such as purple spot disease, root maggot and black mold, it should be sprayed in time and used once every seven days after spraying. Only in this way can the disease be effectively controlled. When the red spider appears on the onion, it can also be directly sprayed with Fenguangling, which can make the red spider disappear as soon as possible.
