摘要
对国外早熟大豆冠层产量分布特点及冠层产量百分比与小区产量的相关性进行了研究。结果表明 :品种之间在产量空间分布的上层产量及下层产量存在显著差异 ,中层产量差异不显著 ;上层产量与小区产量呈显著正相关 ,下层产量与小区产量呈显著负相关 ,中层产量与小区产量无明显相关 ;在产量冠层结构中 ,上中层产量占全株产量比重较大的品种 。
The character of canopy yield distribution of premature soybean and the correlation of the ratio of canopy yield with plot yield were analyzed. The results showed that, among the varieties, the ratio of both upper canopy and lower canopy yield had significant difference. The ratio of the former and latter with the plot yield showed positive and negative correlation respectively. So we can conclude that the ratio of the yield of upper canopy is important, it should be taken as an index of selection on high yield variety.
