摘要
将临汾市尧都区1954年至2001年小麦产量年增量和其全生育期降水量进行同步统计分析得出:小麦生产全生育期降水量大于同期降水平均值20%,则绝大多数是增产年;小麦生育期降水量少于同期降水平均值50%,则是欠收年;当小麦全生育期降水量在同期降水平均值-50%至20%之间时,小麦是增产?或是减产,由其它影响小麦产量因素决定。
The annual increment of wheat output and precipitation during whole breeding season from 1954to2001in Yaodu section of Linfen are an alyzed statistically.The results s how that when the precipitation during whole breeding season of wheat is more than20%of average rainfall,most of the y ears would be abundant years,but when less than 50%of average rainfall,lean year,otherwise the wheat out oput decided on other factors.
