| 摘 要： | 运用灰色关联度分析方法，以五常市为例对水妥产量构成因素进行分析比较，结果表明在水稻产量构成因素的几个因子中，其贡献率依次为穗／穴＞粒／穗＞结实率＞千粒重＞穴／m^2，说明每穴穗数及每穗粒数对产量的贡献最大，在今后的生产过程中，宜选择穗 大粒多及分蘖力强的品种作为当地的主栽品种。为五常市的水稻生再上新台阶了理论依据。表５，参１。

| Abstract: | The poper analyzed the yield components in rice plant.With the method of grey correlation analysis,the result showed that in yield components,the order of contribution rate was panicles per hill,spikelets per panicle,fulfilled grain percentage,grain weight and hills per m2 respectively.This indicated that panicles per hill and spikelets per panicle were the main factors to affect the yield of rice plant.So heavy panicle cultivars with high ability of tiller will be the major cultivars in farming practice.The result also supplied with theoretical basis for next yield step of rice production in Wuchang city. |
