北亚热带冬春季豆科牧草旱作条件下的适应性评价

Adaptability Evaluation of Legume Pasture Species Under Dry Cultivation in Northern Sub-tropical Areas

在北亚热带旱作条件下对10个冬春季豆科牧草品种的物候期、牧草和种子产量、抗逆性进行测定和评价。试验结果表明：皮特曼黄花鸡足豆（Ornithopus compressus cv．Pitman）、马德拉黄花鸡足豆（Ornithopus compressits cv．Madeira）、凉山光叶紫花苕（Viciavillosa cv．Liangshan）、云光早光叶紫花苕（Vicia villosa cv．Yunguangzao）表现出较好的生产性能和适应性，适宜在北亚热带旱作条件下种植。楚雄南苜蓿（Medicago polymorpha cv．Chuxiong）在北亚热带旱作条件下不能进行正常的生殖生长，但牧草产量较高，可进行饲草生产种植利用。

10 legume pasture species were planted under dry Cultivation in sub-tropic areas; various testing and evaluating works have been done on their phenophase, pasture yield, seed yield, plant resistance. Test result is indicated that the production performance and adaptability of Ornithopus compressus cv. Pitman, Ornithopus compressus cv. Madeira, Vicia villosa cv. Liangshan, Vicia villosa cv. Yunguangzao are good. The four pasture cuhivars are suitable to northern sub-tropical areas under dry cultivation. In adition, Medicago polymorpha cv. Chuxiong can not reproduce, but more high pasture yield than others. It can be also planted under dry cultivation in sub-tropic areas as forage vegetable.
