干热风是影响我县小麦生产的主要自然灾害之一。小麦感受干热风后,生理活动失调,碳水化合物合成量降低,灌浆速度减缓,甚至青干枯死。我县近两年小麦播种面积达一百二十万亩以上,按轻型干热风造成小麦减产百分之十计算,要损失小麦六千万斤,按重型干热风使小麦减产二至三成计算,全县要损失小麦一亿二千万斤以上。为了正确预测干热风的发生,早作预
Dry hot air is one of the major natural disasters affecting wheat production in our county. Wheat feel dry hot air, the physiological activity disorders, lower carbohydrate synthesis, filling speed slowed down, or even dry green dead. In the recent two years, the sown area of wheat in our county has reached over 1.2 million mu. According to the light dry-hot wind, the wheat output is reduced by 10%. If we want to lose 60 million kg of wheat and reduce the output by 20% to 30% The county will have to lose more than 120 million pounds of wheat. In order to correctly predict the occurrence of dry hot wind, as early as the pre-
