摘要
Abstract
According to the wheat dry-hot wind disaster grade(QX/T 82-2019)standard,the number of dry-hot wind days,the weather process,the annual type and occurrence time of dry-hot wind in this period were investigated.The occurrence law of dry and hot wind disasters in Zhaoyuan and its impact on winter wheat were summarized,and the corresponding defensive methods were put forward.Based on the meteorological observation data and wheat growth period observation data from 1978 to 2023 in Zhaoyuan City,the dry hot wind of high temperature and low humidity type from May 21 to June 10 and the dry hot wind of post-rain green type from June 1 to June 10 were studied using Mann-Kendall mutation test and linear regression.The results showed that wheat dry hot air was mainly light type,both annual and internal changes showed periodic oscillations,the linear trend showed a slow decline,the mutation point was 2004,and it rose linearly to the highest value and then decreased.The integrated technology of green,high quality and efficient production of wheat with the goal of improving fertilizer and water control ability,crop resistance ability and dry hot air defense ability can reduce the harm of dry hot air to wheat and provide technical support for wheat production in Zhaoyuan.关键词
