河西走廊是北方麦区小麦干热风危害较重的地区之一。在六十年代,甘肃省气象局和有关单位就曾对河西走廊小麦干热风进行过调查研究;七十年代后期以来,在北方小麦干热风科研协作组的统一组织布署下,省气象局又组织武威、张掖和玉门镇等地的农气站和气象站,对干热风防御措施进行了较全面深入的试验研究,突出地进行了春小麦适时早播,筛选早熟和抗干热风品种,带状种植,喷洒草木灰水和化学药剂(氯化钙、磷酸二氢钾、矮壮素、硼酸、阿斯比林等)处理,营造护田林带和适时适量灌水等防御措施的研究,取 The Hexi Corridor is one of the areas where wheat dry-hot wind in the north wheat area harms more heavily. In the 1960s, Gansu Provincial Meteorological Bureau and relevant units once conducted a survey of dry and hot wheat in the Hexi Corridor. Since the late 1970s, under the unified organization of the northern wheat dry and hot wind scientific research team, We organized farmer stations and weather stations in Wuwei, Zhangye and Yumenzhen to conduct a comprehensive and in-depth experimental study on the defensive measures of dry and hot winds, highlighting timely and early sowing of spring wheat and screening of precocious and anti-dry hot-wind varieties Like plantation, ash water and chemicals (calcium chloride, potassium dihydrogen phosphate, chlormequat, boric acid, Aspirin, etc.) to create defensive measures such as shelterbelt and timely irrigation
