There are many pests on grape seedlings in summer. How to manage them?
Let's talk about the management of grapes in summer. For grapes with weak growth, all grapes should be picked within three to five days after July 20. After coring, five leaves will remain at the top of all secondary branches, and only one leaf will remain for the rest. The purpose of this is to control the wild growth and unnecessary nutrient consumption of grapes, concentrate nutrients on the main branches, make the root system increase rapidly, and lay the foundation for safe overwintering and growth in the coming year. Seedling growth needs a lot of nutrients. In addition to applying base fertilizer when planting, topdressing should be done in time after planting, which can help grape seedlings to return to normal growth. Be careful not to use too much when fertilizing. During the management period, a lot of fertilization is needed. The main type of fertilizer is nitrogen fertilizer, which can be combined with some organic fertilizers. When organic fertilizer is used, it must be completely decomposed. From June 1 day, we need to water and fertilize every ten days. Before watering, dig a pit at a distance of 0/5cm from the vine/kloc-0, and apply 5 to 0/0g of urea. With the growth of vines, the demand for nutrients increases, and the amount of fertilization can be appropriately increased. The above is my answer, I hope it will help you.
