牛鞭草种质资源在中国的分布及其人工草地建植技术

牛鞭草为一种高大型C4禾草,其分布较广,主要分布在热带、亚热带和北半球的温带湿润地区。牛鞭草在我国已知的有4种,各种的分布有所不同。牛鞭草由于适应性广、耐刈割、产量高、品质好,被广泛种植,但由于长期单一种植造成草地严重退化,从而影响了该草的产量和品质,因此本文还从牛鞭草的建植和管理技术方面作了一定的论述。

The Distribution Characters and Planting Technology of Hemarthia spp

Hemarthia spp.is a high-quality,productive,evergreen wild perennial forage.It is very resistant to high temperature and draught in summer as frost and snow on winter.It tastes palatable and is nutritious for animals but it is sucha tpical clonal grass that it yields few viable seeds for germination.However,crude protein contents lower if compared with the nutritive requirement of ruminant animal.In order to improve the forage quality,lim-pograss pasture was established by mixing with legumes.Study of planting and mixing technologies were analyzed and discussed in the article.
