黔育1号菊苣与紫花苜蓿、鸭茅间作栽培效果研究

摘要： 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。

Abstract: According to the climatic characteristics and the forage planting needs in Songtao Miao autonomous county of Guizhou Province, intercropping experiments were carried out with Qianyu No. 1 chicory, Beilin No. 202 alfalfa and Qiancao No. 4 cocksfoot, respectively. The yield-increase benefit of intercropping mode of Qianyu No. 1 chicory with different varieties of forage was assessed by comparing and analyzing the yield, nutritional quality and production efficiency under intercropping or monocropping condition. The results showed that the annual yield of fresh grass was 87.27 t/hm2 when Qianyu No. 1 chicory was intercropped with Beilin No. 202 alfalfa, which was increased by 36.17% compared to the monocropping of alfalfa; the yield efficacy was improved by 20.77%, and the protein content was 26.83%. The results obtained in this study may provide technical support for the development of the grasslands and animal husbandry industry in this region.

Key words: Qianyu No.1 chicory, alfalfa, cocksfoot, intercropping, monocropping
