黔育1号菊苣与紫花苜蓿、鸭茅间作栽培效果研究
Animal Husbandry and Feed Science(2019)
Abstract
依据贵州省松桃县的气候特点和牧草种植需要,用黔育1号菊苣与北林202紫花苜蓿、黔草4号鸭茅分别进行间作试验,从产量、营养品质、生产效益等方面对间作复合群体与3种牧草单播进行比较分析,探讨黔育1号菊苣与不同牧草间作种植模式的增产效益.结果表明,在贵州松桃地区,黔育1号菊苣+北林202紫花苜蓿间作,年均鲜草产量可达87.27 t/hm2,比紫花苜蓿单播产量增加36.17%,生产效益提高20.77%,粗蛋白含量达26.83%.该研究结果可为松桃县种草养畜产业的发展提供技术支撑.
