中亚热带冬季牧草引种和混播组合试验

Trial of Introduction and mix-sowing Combination of Winter Forage Varieties in the middle Subtropics

田间种植试验表明,在供试的17个牧草栽培种中,适宜云南中亚热带秋播的冬季豆科牧草为云光早光叶紫花苕、环峡南苜蓿、银子蜗牛苜蓿和盛世紫花苜蓿;禾本科牧草为杰威和特高多花黑麦草。在3个混播组合中,豆禾草比例均衡,干物质产量较高的组合是云光早光叶紫花苕+特高多花黑麦草。

The experiment on introduction of winter forage varieties was carried out in the middle subtropics region of Yunnan in autumn . The results showed that in the 17 forage varieties, the leguminous grasses （Vicia villosa .cv. Yunguangzao, Medicago polymorpha, cv. Circle vallery, Medicago scutellate.cv.Silver and Medicago sativa, cv. millennium ） and gramineous grasses （Lolium multiflorum.cv.Splendor and cv.Tetragold）were suitable to be planted in middle subtropics region. In the 3 mix-sowing combinations,the combination of Vicia villost.cv.Yunguangzao＋Lolium multiflorum.cv.Tetragold was the best with balanced component proportion of gramineous and leguminous grasses and high dry matter yields.
