贵州自然条件优越，适宜多种牧草的生育繁衍，贵州的野生牧草种质资源丰富，共203科1205属4725种（包括变种）。贵州草地资源丰富，草地面积广，全省零星的草山草坡和成片的草山草坡面积共6430亩，占全省土地面积的24.3%。在牧草生产性能方面，由于贵州优秀的水热条件，生长性能较高，表现在以下几个方面（1）植株高大；（2）叶茎比大；（3）利用期长；（4）再生性好；本次试验对贵州的牧草资源进行文献综述以及对黔东南境内常见野生饲草进行生产指标测量。本试验选取了高羊茅、看麦娘、白三叶、野豌豆四种饲草进行了株高，鲜干比，茎叶比等测定。结果表明，高羊茅在5月初至5月中旬仍具有较高的生长速度，为是四种牧草中最高；白三叶的叶量更加丰富，白三叶的茎叶比显著低于野豌豆（P＜0.05）；高羊茅的含水量较低，野豌豆和白三叶的鲜干比都显著高于高羊茅（P＜0.05）。

贵州牧草资源概况及黔东南几种牧草生长表现的研究
GENERAL SITUATION OF GUIZHOU FORAGE RESOURCES AND RESEARCH ON GROWTH PERFORMANCE OF SEVERAL FORAGES IN SOUTHEAST GUIZHOU
ABSTRACT: Guizhou has excellent natural conditions and is suitable for the growth and reproduction of various forages. Guizhou is rich in wild forage germplasm resources, with a total of 4725 species (including varieties) of 1205 genera in 203 families. Guizhou is rich in grassland resources and has a large grassland area. The scattered grassland and grassland slopes in the province have a total area of 6,430 mu, accounting for 24.3% of the province’s land area. In terms of forage production performance, due to the excellent hydrothermal conditions in Guizhou, the growth performance is higher, which is manifested in the following aspects: (1) tall plants; (2) large ratio of leaves and stems; (3) long utilization period; (4) better reproducibility; This experiment conducted a literature review of the forage resources in Qiandongnan and measured production indicators of common wild forages in Guizhou. In this experiment, four forage grasses, such as tall fescue, Alopecurus aequalis, white clover, and wild pea were selected for plant height, freshtodry ratio, and stemtoleaf ratio. The results show that tall fescue still has a high growth rate from the beginning of May to the middle of May, which is the highest among the four forages; The leaf quantity of white clover is more abundant, and the stemtoleaf ratio of white clover is significantly lower than that of wild pea (P<0.05); Tall fescue has a lower water content, and the freshtodry ratio of wild pea and white clover is significantly higher than that of tall fescue (P<0.05).
