摘要
干热风使麦田动量、热量、水汽量的湍流交换骤增、而且持续，破坏了农田正常的热量平衡、水分平衡条件，导致作物有机合成的紊乱，造成减产。为减轻其危害，要重视选用抗干热风的小麦品种，同时，要改善农田小气候。
Turbulent exchange of momentum,quantity of heat and vapour in the wheat fields increased suddenly, sustained continuously in the case of the weather of dry hot wind,which destroyed the normal heat and water balance and resulted in the orderof organic synthese and caused yield reduction. In order to reduce its damage ,attentionshould be paid to the selection of wheat cultivars resistant to drv and hot wind ,and atthe same time,measures must be adopted to improve the micro一climate in the farm-lands.
