【摘要】 通过不同品种（系）和密度的超高产栽培试验，分析四因子和二因子的产量效应，各因子对产量贡献的大小为：亩荚数＞百粒重＞荚粒数。超高产育种和栽培的主攻方向是提高亩荚数，同步增加百粒重。黄淮超高产育种模式：亩荚数４６．７±５．３万，百粒重２２．４±２．６克，每荚粒数２．１８±０．１１个。更多还原

【Abstract】 Twelve cultivars of different plant types were chosen to test yield effect of four factors and two factors in different plant population density. The results showed that the characters affecting yield were No.of pods mu>100 seeds weight>No.of seeds per pod.The best breeding model of super-high yield recommended for the Huang-Huai Plain could be No.of pods per mu 467±53 thousand, 100 seeds weight 22.4±2.6g and No.of seeds per pod 2.18±0.11.更多还原
