将1956—1981年的资料用统计学方法进行了分析,结果认为,降水量影响产量的关键时期是12月份,12月份每增加1毫米降水,气象产量相应增加2.65斤。2月和5月的降水多少对产量也有一定影响。气温不是影响小麦产量的限制因子,但10月和12月的平均最高气温显著地左右着产量的形成,呈负相关。影响气象产量的日照时数关键期主要在12月份。根据分析结果,以下技术措施必须
The statistical analysis of the data from 1956 to 1981 shows that the key period of precipitation affecting production is December, and every 1 millimeter of precipitation in December increases the meteorological output by 2.65 kg. The precipitation in February and May also had some effect on the yield. Temperature is not a limiting factor affecting wheat production, but the average maximum temperatures in October and December are significantly negatively correlated with yield formation. The key period of sunshine hours affecting weather output mainly lies in December. According to the analysis results, the following technical measures must be
