干热风是我县小麦生育后期的一种主要气象灾害,每年都有不同程度的发生,一般受灾减产10％左右,严重者减产20％以上。因此,研究予防干热风为害的有效办法,是提高小麦单产的重要课题。一九七八年我县农科站和气象站联合在西北湾分社西湾大队二生产队进行了氯化钙闷种予防干热风效果试验,证明方法简便、效果显著,有推广价值。
Dry and hot wind is a major meteorological disaster in the later stage of wheat growth in our county. It occurs in varying degrees every year. Generally, the affected area reduces the output by about 10% and the serious ones reduces the output by more than 20%. Therefore, the study of effective ways to prevent dry hot wind is an important issue to improve wheat yield. In 1978, the county agricultural station and weather station in the Northwest Gulf branch of the West Bay Brigade two production teams carried out a sieve of calcium chloride to prevent dry hot air effect test proved the method is simple, the effect is significant, with promotional value.
