摘要
经两年观测试验,供试热带主要豆科牧草以笔花豆属的184笔花豆的产量最高,其适应性、抗病力均强,年亩产鲜茎叶4891公斤,比目前推广的格雷厄姆笔花豆增产76.9％,它适用于改良草地、刈割利用或晒制干草粉。5065大果蝴蝶豆高产优质,较耐荫,宜同丛生禾本科牧草混种改良草地,也可作为多年生作物园的绿肥覆盖作物种植用以保持水土、改良土壤,但种子生产成本高。园叶舞草为海南野生种,茎叶产量、粗蛋白质含量均比异果山绿豆、卵叶山蚂蝗高,可作为刈用草饲养动物。
Cutting, trials were conducted to evalute 21 legume cultivars in pure swards for two years. Slylosanthes guianensis(CIAT 184)gave the hightest yield,which was more persistent and high yielding than other cultivars. It showed tolerance to plant disease and its annaul fresh forage yield is 4891kg/mu. CIAT184 is suitable for pasture improvement, cutting and forage meals production. Centrosema macrocarpum (CIAT5065)gave a high yield with better shade endurance. It is suitable for pasture improvement and as a cover crop on plantation to prevent soil erosio and improve soil condition. Desinodium gyroules is native to the hilly areas in Hainan. It's better than Desmodium heterocarpon(L) DC and Desmodium ovalifolium in fotage fresh forage yield and crude protein content. It's suitable for cutting and as a feed for animals. Whether it is useful for pasture improvement or not awaiting further investigation.
