扁穗牛鞭草的他感作用研究

扁穗牛鞭草是我国南方重要的饲草来源,但在与豆科牧草混播时却难以成功,因为它具有较强的竞争能力和对其他植物的排斥作用。本研究通过牛鞭草根、茎、叶浸出液对豆科牧草种子发芽率和发芽势的影响,以寻找能与扁穗牛鞭草混播的草种,以提高牧草的产量和质量。试验结果表明,牛鞭草的根浸出液对所有试验豆科牧草种子(川引拉丁诺白三叶、Dory红三叶,Cherokee红三叶、巫溪红三叶、箭三叶)均有抑制作用,而茎、叶浸出液对豆科牧草种子的抑制作用不明显。

Limpograss is an important forage in south China and it can not mix with other grass .After carefully research, we find it has strong competition and can not be compatidle with other grass. In this paper, the author studied the secretion of root, shoot, leaf affect the germination of Legums in order to find some suitable grasses to mix with limpograss and it and search the best increase product of forage. The results showed that the extraction of the root have significiently effects on germination of Legumes, but the extraction of the shoot , leaf did not inhibite germination of legumes.
