Second, give birth to germination fertilizer. Before the budding of grape, 5-10 kg of urea or 1-5 kg ​​of compound fertilizer of nitrogen, phosphorus, and potassium should be applied before the budding of the grape. Boron and magnesium sulfate should be rejected by each other. Application method: Ditch the groove on both sides of the plant. After the application or the whole garden is applied, it is slightly turned. With good germination fertilizer, it plays an important role in the sprouting of grapes and the growth after germination.
Third, pay close attention to the new development of grape seedlings planting work. Before planting, we must do a good job of land consolidation and seed disinfection. After the seedlings are planted, they should be poured with enough water, and a 50 cm wide plastic film should be laid in order to facilitate moisturizing and increase the temperature of the soil and promote the survival of the seedlings.
Fourth, do a good job in the disinfection of the spring garden's clear garden to kill pathogens and insect pests that survived after the winter. It is very important to pay close attention to the disinfection and disinfection of the Qingyuan Garden of the spring vineyards, to prevent and control diseases and pests, and to reduce the number of pests and diseases in the park. It must be highly valued. Method of implementation: Before the buds have inflated and there are no visible green balls, the whole park thoroughly sprays a lime sulfur mixture with a concentration of 3 to 5 Baume degrees. Special attention should be paid to the fact that after the buds of the grapes have been expanded, lime sulfur cannot be sprayed. In addition, when the young leaves of the grapes are exposed, 800-fold mildewin can be used for further sterilization, which is a key drug for preventing and controlling blackpox.
5. Prepare agricultural materials needed for the post-emergence grape growth period, especially the procurement of pesticides. When purchasing pesticides, it is necessary to purchase products that are allowed to be used in the production of pollution-free and green foods; to inspect the “three certificates†of the products and to prevent the purchase of “three nothings†products; pay attention to checking the validity period of the products.
