病虫害是直接影响葡萄产量、品质的重要因素,而葡萄生长后期烂果是危害葡萄产量的最主要原因。为避免葡萄生长后期出现烂果现象,人们常大量使用化学农药,不仅造成葡萄农药残留量超标,还对环境造成污染。因此实际生产过程中,应贯彻“预防为主,综合治理”的植保工作方针。下面结合葡萄生长后期烂果的发生原因及防治进行如 Pests and diseases are the important factors that directly affect the yield and quality of grapes. The rotten fruit in the late growth stage of grapes is the most important reason that harms the yield of grapes. In order to avoid the phenomenon of rotten fruit in the late stage of grape growth, people often use chemical pesticides in large quantities, which not only causes excessive pesticide residues in grapes but also causes pollution to the environment. Therefore, in the actual production process, the principle of “prevention first, comprehensive management” should be implemented. The following combination of grape growth in the late rotten fruit causes and prevention of such as
