摘要
对4个大豆品种与牛筋草的竞争关系进行了研究,结果表明,不同大豆品种对杂草干扰的反应有显著差异,大豆种子产量损失率在25%~38%;牛筋草生物量和单株种子重量受大豆影响而显著降低,但大豆品种间没有显著差异。
The competition between 4 soybean varieties and goosegrass (Eleusine indica) was studied. The results have shown: Varietal differences in responses to weed interference were detected in soybean.The grain yield loss of soybean by weed competition ranged from 25% to 38%; The goosegrass biomass and seeds weight per plant were decreased by soybean too, but there was no difference among soybean varieties.
