近年来,我国的农药行业正飞速发展,农药的种类、剂型等都不断地除旧布新,因而对其应用技术水平的要求也相应提高,并趋于专业化。在农药的使用过程中,如不谨慎就极易产生药害,影响农作物的生长,造成大面积减产,严重时甚至会颗粒无收。五种原因要分清(1)药剂本身质量有问题;(2)气候条件。一般情况下,夏季喷药发生药害数占全年药害80%以上。另外,在降雨后,晚间湿度大,夜间果面有水珠,喷药后易产生药害;(3)喷打不均匀,操作有问题;(4)选择的施药器械错误或者其不够洁净。如使用一些给果树喷施农药
In recent years, the pesticide industry in China is developing rapidly. The types and dosage forms of pesticides are continually removed from the old cloths. Therefore, the requirements on the applied technology level are correspondingly raised and tend to be specialized. In the process of pesticide use, if not careful it is easy to produce phytotoxicity, affecting the growth of crops, resulting in large-scale production cuts, even in severe cases crop failure. Five reasons to distinguish (1) the quality of the pharmaceutical itself is a problem; (2) climatic conditions. Under normal circumstances, the number of pesticide injury occurred in the summer spray accounted for more than 80% of the whole year. In addition, after the rain, night humidity, night fruit surface with drops of water, spraying prone to injury; (3) uneven spray, the operation of a problem; (4) the choice of pesticide application error or not clean enough . Such as the use of some fruit trees spraying pesticides
