夏季降水对小麦播前产量预测方法的研究

降水是影响小麦产量的气候因素中最主要的一项.小麦单产不仅受生育期间降水量的制约,而且在很大程度上还被夏季休闲期的降水量所左右.通过对历史资料的分析,找出夏季降水对小麦产量影响的一般规律,进一步找出利用夏季降水的丰缺程度对翌年小麦产量趋势作出预测的方法,对于指导小麦生产趋利避害,巧用气候资源,合理组装小麦生产的配套技术,以及最大限度的利用自然降水资源,促进小麦单产大幅度提高,具有十分重要的意义.

Study on Predict Method of the Wheat Yield by Precipitation in Summer

Precipitation is one of major weather factors influencing wheat yield.Wheat list produce is not only restrict by the amount of precipitation during growing time,but also by the amount of precipitation on summer recreation peried.Through the analysis on the history data,we find out the rule that precipitation how to effect on wheat yield in summer,and how to estimate the wheat yield trend of next year.It is important to direct the wheat production,and to promote the wheat yield.
