(9) One week later, 100 g/mu potassium dihydrogen phosphate is sprayed and water is sprayed once.
5) And (3) pest control: spraying a bactericide and an insecticide;
the first time of using the bactericide is to spray the bactericide to the potatoes in the middle 6 months before sealing ridges so as to prevent the seed potatoes from being diseased. Then, the bactericide is used according to the growth condition in the field and the weather condition to prevent and control fungal diseases and bacterial diseases such as early blight, late blight and the like.
Insecticides are used according to field conditions. Underground pests are more harmful after sowing and before ridge sealing, and the underground pests migrate downwards along with the rise of the ground temperature and are less harmful, such as wireworms, grubs, cutworms and the like, so that the underground pest insecticide is used after sowing and before ridge sealing. After seedling emergence, low-toxicity chlorpyrifos is applied along with water during watering for prevention and treatment. Aphids are the main transmission vector of potato viruses and therefore need to be controlled.
