通过不同年份生育期间有效积温和日照对水稻品种农艺性状关系的分析得知，有效积温对各农艺性状的相关表现为空秕率（0．4696**）＞穗粒数（-0．4063*）＞千粒重（-0．4014*）＞有效穗数（0．2511）＞株高（-0．0843）＞产量（0．0598）；日照对各性状相关性为穗粒数（0．5889**）＞空秕率（0．3843）＞千粒重（-0．2047）＞株高（0．0700）＞有效穗数（0．0155）＞产量（-0．O123）；温光对产量的回归方程为Y=367．74＋0．0468X1—0.0166X2。
Through the analysis of effective accumulated temperature and sunlight on the agronomic traits of rice cultivars in different years, it was found that the correlation between effective accumulated temperature and agronomic traits was empty rate (0.4696 **)> grain number per spike (-0.4063 * )> 1000-grain weight (-0.4014 *)> panicle number (0.2511)> plant height (-0.0843)> yield (0.0598) **)> emptying rate (0.3843)> 1000 grain weight (-0.2047)> plant height (0.0700)> effective panicle number (0.0155)> yield (-0.O123) The regression equation is Y = 367.74 + 0.0468X1-0.0166X2.
