The high incidence of various diseases such as grape downy mildew, white rot, anthrax, etc. In the summer, downy mildew can lead to deciduous, dead branches, rotten fruit, and even death of grapes. Therefore, in the summer rainy season, we must strengthen the management of vineyards and prevent and treat diseases in time. If there is a disease in the vineyard in the Qingyuan Garden, and there is more rain at this time, it is necessary to clear the park at any time and remove the diseased diseased leaves, diseased branches and diseased fruits from the garden, and bury or burn them. Loose soil in summer and autumn and rainy season, especially after heavy rain and heavy rain, the rain will cause the vineyard land to form a knot, poor soil permeability, resulting in grape root system lack of oxygen, weakened tree vigor, reduced resistance, and thus susceptible to disease. Therefore, in order to increase the permeability of garden soil, the soil should be ploughed once in a deeper time before the rain or during the rain. Treating rainy or rainy conditions and high temperature and humidity, grapes are most susceptible to disease. They should be observed once a day in the vineyards. See the disease at the beginning and immediately spray the medicine. For downy mildew, if you see individual parts of the garden, even if it is found on a grape, you should spray it immediately. The tip of the shoot must be picked up promptly on the grapes, and the tip should be wiped off in time. At the same time, for excessive shoots, we must eliminate some of the shoots, which is conducive to ventilation and light transmission and improve resistance. Excessive fertilization of rain often results in loss of orchard fertility, resulting in weakened tree vigor and reduced self-resistance. Therefore, during the rainy season, fertilization should be applied timely according to the loss of soil fertility and grape growth in the vineyard. Fertilization should be based on the principle of “eat less and more mealsâ€. The fertilizer should be applied sparingly and industriously. The top dressings outside the roots should be combined with spraying, and it is best to spray the fruit foliar fertilizers separately.
