贵州牧草种质资源研究与利用

2003-2005年，对贵州牧草种质资源进行了多次考察收集，收集到14科58属110种共503份，其中禾本科牧草种类最多，豆科及其它杂类牧草较少。经分类鉴定后，将具有一定优良性状、在同一属中有一定代表性的牧草升入二级圃，初步测定其生育期、再生性能、适口性、茎叶比、鲜草产量、营养成分和结实性7个指标，结果表明：所采集到的牧草资源中，品质优良的牧草种类较多，大部分野生牧草都能结实，其中结实率和发芽率都较高的有14种。通过综合指标的分析，筛选出苇状羊茅、鸭茅、扁穗雀麦等9种综合性状较好的野（逸）生牧草可供开发利用。

A Study and Utilization of the Guizhou Herbage Germplasm Resources

In 2003-2005 through reviewing and collecting the Guizhou grassgermplasm resources time af- ter time, 14 families, 58 genus, 110species, total 503 accessions were collected. The species in Gramineae were the most in these species, species in Leguminosae and others were the least. After classifying and identifying, pastures with good characters were taken to the second garden. The bearing period and the regeneration capability and palatablity and radio of the stem to leaf and the fresh grass yield and the nutrition component content and fecundity were analysed initially . The results showed that a lot of herbages had high fresh grass yield and rich leaves and good palatability and excellent quality. Most wild herbage could seed , in which there are 14 species of high seed rate and high germination rate . 9 wild species of good comprehensive traits, such as F. arundinacea and Dactylis glomerata and Hemarthria cornpressa , can be exploited and utilized.
