摘要
经过对2003—2012年降水量对豫北优质夏谷新品种产量的影响进行了分析研究,发现5—7月降水量对夏谷产量影响最大,相关系数R=0.982 04,达极显著水平,相关回归方程为Y=0.738 8X+159.991 0。
Through the analysis on effect of precipitation on yield of new summer millet variety in northern Henan during 2003 to 2012,the results showed that the precipitation during May to July affectd yield of summer millet significantly. The correlation coefficient reached 0.982 04,and the regression equation was Y=0.738 8X＋159.991 0.
