为减少山东省烟台地区葡萄园周年施药次数和施药量,以葡萄霜霉病和葡萄炭疽病的防治为主线,评价葡萄园减少施药次数和施药量的可行性。试验结果表明,试验示范区在周年施药次数比常规防治区减少3~4次、施药剂量减少60%以上、施药成本降低50%以上的情况下,对葡萄霜霉病和葡萄炭疽病的防治效果与常规防治区相当。明确了减少施药次数和施药量的可行性,为葡萄园科学用药提供了依据。 In order to reduce annual number of pesticide application and application rate of vineyard in Yantai, Shandong province, the main control measures of grape downy mildew and grape anthracnose were evaluated. The results showed that in the experimental demonstration zone, the number of annual pesticide application was reduced by 3 ~ 4 times than that of the conventional control area, the application dose was reduced by more than 60% and the cost of pesticide application was reduced by 50% The control effect is similar to the conventional control area. Clear the feasibility of reducing the number of applications and the amount of pesticides, providing a basis for the scientific use of vineyards.
