NATURAL LEGUMINOUS GRASS IN GUIZHOU INTRODUCTION AND DOMESTICATION OF NARROW-LEAF VETCH

对采自贵州省册亨县、三都县的窄叶野豌豆野生种进行了引种驯化。结果表明：其产草量中等，鲜草３７．５～４５ｔ／ｈｍ２，草质优良；生育期短，早熟；种子产量高，收纯净种子５００～６００ｋｇ／ｈｍ２。适合在我国南方中亚热带地区同水稻、玉米轮作。

The wild species of narrow-leaf vetch (Vicia angustifolia) collected from Ceheng County and Sandu County, Guizhou Province were introduced and domesticated. The result showed that the yield of grass was media, the fresh grass produced was 37.5～45t, the grass quality was fine; the reproductive period was short and early, the yield of seeds was high. The production of net seeds was 500～600kg/hm 2.It was suitable for rotation with rice and maize in the area of the middle subtropical zone, and also sowing as a fallow crop.
