云南省牧草品种混播及示范推广研究报告

A report of study on the mix sowing experiments of pasture species and its utilization in Yunnan province

总结三年在思茅、广南和丽江三个试验点分别进行的牧草混播试验,得出在思茅南亚热带环境条件下适宜的混播组合为:大叶千斤拔+阿玛瑞罗落花生+贝斯莉斯克伏生臂形草;在广南中亚热带环境条件下适宜的混播组合为:纳罗克非洲狗尾草+威提特东非狼尾草+海法或拉丁诺白三叶+绿叶或银叶山蚂蝗;在丽江温带环境条件下适宜的混播组合为:海法白三叶+雷得昆红三叶+猎人田紫花苜蓿+沙弗蕾肯尼亚白三叶+波特鸭茅+德梅特苇状狐茅+维多利亚多年生黑麦草。据此结论,分别在思茅、广南和丽江各建植133 3hm2共400hm2的示范草场,为相似生态环境进行大面积的草场改良提供理论和实践的指导依据。
