贵州黔西北地区巨菌草与多花黑麦草套种技术

Intercropping Techniques of Mycorrhiza and Lolium Multiflorum in Northwest of Guizhou,Guizhou Province

针对贵州黔西北地区草地生态畜牧业发展中草畜不配套、草料供应不足的问题,黔西北大力开展粮改饲,力保草畜平衡,积极探索牧草套种或轮作技术,提高牧草产量。巨菌草和一年生多花黑麦草是黔西北主要种植的2个牧草品种,目前以单播为主,缺乏套种的指导技术。该文从区域选择、品种及质量要求、种植方法、套种方案、田间管理与施肥、刈割模式、产量评估与利用等进行阐述,为开展巨菌草与一年生多花黑麦草套种提供技术指导。

In response to the problems of inadequate grass and livestock production and insufficient forage supply in the development of grassland ecological animal husbandry in the northwest of Guizhou Guizhou,a major effort has been made in the northwest of Guizhou province to promote grain-based feed reform and maintain a balance between grass and livestock production,the technology of interplanting or rotation of forage was explored to improve forage yield.Giant fungus and annual lolium multiflorum are the two main forage species in northwest Guizhou.This paper expounds regional selection,varieties and quality requirements,planting methods,interplanting schemes,field management and fertilization,cutting patterns,yield evaluation and utilization,etc.,the study provided technical guidance for interplanting of mycorrhiza with annual Lolium multiflorum.
