First, the initial disease, timely prevention and treatment to adhere to the prevention of prevention, a comprehensive observation of the vineyard a day, seriously do a good job in forecasting and disease prediction, found that the disease, timely medicine for the prevention and treatment of spraying. For example, downy mildew occurs almost to varying degrees every year. In particular, about 10 days before the beginning of autumn, when the temperature difference between day and night is above 10°C, it is most susceptible to disease. At this time, it must be fully observed. See the incidence of individual light plants in the garden, that is, spraying. With 70% of Cobo 600 times, 80% of 300 aluminum diethylphosphine or 1:0.7:180 times Bordeaux spray, a good control effect. Second, the main Bordeaux fluid, with other agents properly in the grape disease prevention process, with Bordeaux fluid as the main line, with other agents properly, the disease prevention effect is very good, in front of a spray 1:0.7:220 times liquid , The spray of grape is sprayed once 1:0.7:200 times. After the grapes were harvested, they were sprayed once with 1:1:1180 times and sprayed 1-2 times in the autumn with 1:1:160 dilution. If white rot, anthrax and other diseases occur in the middle, symptomatic spraying will occur. These drugs are mostly acidic, with strict control of Bordeaux mixture intervals. Third, increase the amount of fertilizer in an appropriate manner to increase tree potential, increase the resistance to rainy season will cause the loss of fertility, weaken the tree vigor and reduce the resistance. Therefore, in the rainy season, the amount of fertilization should be appropriately increased according to the loss of soil fertility and the growth of the grapes. It is necessary to use the method of “eat less, eat more†and apply less fertilizer. Especially sandy soil land. Fourth, timely soil loosening, increase soil permeability Rainy season, especially heavy rain, heavy rain, the vineyard will be ground surface hardening, poor soil ventilation, resulting in grape root system lack of oxygen, weakened tree vigor, anti-biotic reduction, susceptible to disease. Therefore, one should cultivate the soil deeper before the flood season. During the rainy season, we must pay close attention to the rainy days and cultivate the vineyards to increase the permeability of the soil. Fifth, clean up the vice cuts, in order to facilitate ventilation, ventilation and rainy season, the grape is easy to grow long and the incidence of the shoot is very high. It is necessary to timely pick up the grapes and erase the shoots in time. At the same time, excessive shoots of new shoots should be cleared as appropriate, which is beneficial to ventilation and improve resistance. VI. Clearing the garden in a timely manner to curb the spread of the disease. If a disease occurs in the vineyard, it is rainy, watery, hot and humid, and the disease is most easily transmitted. Therefore, we must clear the garden at any time. The diseased sick leaves, diseased branches and diseased fruits in the garden are cleared out of the garden, buried deeply or burned. At the same time, the weeds in the garden should be promptly removed. When cutting the diseased branches and fruit, the scissors should be cleaned and disinfected to prevent cross-infection. If farmers do the above disease prevention measures during the rainy season, generally there will not be a large area of ​​disease. (Extended County Cuipingshan Park Management Office)
