甘肃省河西走廊气候干燥、雨量较少,在葡萄栽培过程中很少有病害发生,加之日照长,昼夜温差较大,对发展葡萄具有得天独厚的条件。但近两年来,由于降雨量增加,特别是六、七月份有较多的雨水,雨后天气又高温干旱,不但影响葡萄受精、座果,而且也使葡萄病害滋生,特别是葡萄的白粉病蔓延较快,影响了葡萄生产,是值得引起注意的问题。
Hexi Corridor in Gansu Province has a dry climate and low rainfall. Few diseases occur during the cultivation of grapes. In addition, the sunshine duration is long, and the temperature difference between day and night is large, which is a unique condition for the development of grapes. However, in the past two years, due to the increase of rainfall, especially in June and July, there is more rain and the weather is very hot and dry after the rain, which not only affects grape fertilization and fruit set, but also causes grape diseases, especially grape powdery mildew Spread quickly, affecting the production of grapes, is worth the attention of the problem.
