摘　　要：用黔草1号高羊茅种子为试验材料,采用大、小粒种子分别单种和大、小粒种子混合种植进行试验,研究结果表明:大粒种子形成的繁殖体较大,等级差异较小,产量较高;小粒种子形成的繁殖体较小,等级差异较大,产量较低;大小粒混植群体的繁殖体其大小和差异变化不一,产量居中。Potculture experiment was conducted byindividual plantinglarge ,small and mixed seeds respectivelyofTall Fescue Qiancao No·1.The results showed that: Compared with the reproductive body from small seeds , thereproductive bodyfromlarge seeds was larger.The hierarchy difference was smaller and seed yield was higher.Meanwhile,the size and hierarchydifference ofthe reproductive bodyfrommixed seeds was variant, seed yield was mediate.
