不同稻作下巴西陆稻产量性状的效应分析

Effect of Traits of Brazilian Upland Rice on Its Yield in Different Cropping Systems

采用笔者自行设计并创立的CRPGFSC法 ,分析了不同稻作下巴西陆稻的性状对产量的效应。结果表明 :不同稻作下巴西陆稻产量性状的综合总效应为基本苗 >全生育期 >有效穗 >始穗至成熟天数 >穗粒数 >结实率≈千粒重 >播种至始穗天数 ;CRPGFSC统计分析法是一种科学、准确。

The effect of traits of Brazilian upland rice on its yield in different cropping systems was analyzed by CRPGFSC method which included multiple linear regression,path coefficient analysis,grey relation analysis,fuzzy subordinate function and fuzzy comprehensive evaluation,the results showed that the order of traits was basic seedlings per hectare>total growth and developmental duration>effective panicles per hectare> days from initial heading to ripening>grains per panicle>setting rate≈kilo-grain weight>days from sowing to initial heading according to their comprehensive effects on yield;CRPGFSC method was a scientific,accurate and dependent method of analyzing numeral factors.\;
