为了充分发挥河套自流灌区的自然优势,减轻灾害性天气的危害,大幅度提高小麦单产和总产量,从1975年起,我们较系统地开展了以“干热风”为主的不良农业气象条件对小麦粒重和产量影响的研究,并同时进行了防御措施的调查总结和试验研究工作。 In order to give full play to the natural advantages of the Catchment Irrigation District, reduce the harm of disastrous weather and greatly increase the yield and yield of wheat, since 1975, we systematically carried out a series of adverse agro-meteorological conditions including “dry and hot wind” Wheat grain weight and yield impact of the study, and at the same time conducted a defensive measures survey and experimental work.
