摘要

该文在分析大量试验资料后指出:在黄土高原南部地区

冬小麦产量与播前底墒相关性强

其相关系数在不同施肥水平下

分别为:中肥处理0.677;高肥处理0.742;单施氮处理高达0.960。因而得出的不同施肥处理下的底墒与冬小麦产量关系图

可用于冬小麦产量趋势预测及建立数学模型参考。

Abstract

After studied a great deal of experimental data

the writers pointed out that the soil moisture is related very well with the yield of winter wheat in the south of Loess Plateau and the best relation coefficient is 0. 960. On the basis of this the graph of soil moisture-winter wheat yield relation under the different fertilizer style or level had been obtained.This graph may be used for the general trend forecast of winter wheat yield and reference in setting up the mathematical model.
