我区位于长江中游的江汉平原,小麦在夏收作物中占有重要地位,常年种植面积在300万亩以上,可是产量不高不稳。解放30年来,虽然单产和总产分别增长了2.6倍和6倍,然而却上下起伏了十一次。产量变动的原因,除人为因素影响外,主要是受小麦生育期间降水量过多所引起的渍害和赤霉病两大灾害造成的。本文拟就降水量对小麦产量的影响进行分析,并提出解决意见与措施,供有关部门参考。
My area is located in the Jianghan Plain in the middle reaches of the Yangtze River. Wheat occupies an important position in summer crops. The perennial planting area is above 3 million mu, but the yield is not high and unstable. In the 30 years since the liberation, although yields and total output have increased by 2.6 times and 6 times, respectively, they have fluctuated eleven times. The reasons for the change in output are mainly caused by the two catastrophes and the head blight caused by excessive precipitation during wheat growth except for human factors. This paper intends to analyze the impact of precipitation on wheat yield, and put forward suggestions and measures for the reference of relevant departments.
