摘　　要：[目的]为研究并推广核桃林下种植饲草技术,促进云南省保山市草食畜牧业发展。[方法]选择当地的常见饲草品种,以多种组合方式进行核桃林下种植作业设计:多年生品种组合混播(鸭茅+多年生黑麦草+白三叶、高羊茅+多年生黑麦草+白三叶、高羊茅+白喜草+白三叶3个组合品种混播);多年生高大禾草单播(巨菌草、皇竹草单播);1年2季轮作(夏季种植苏丹草、高丹草,冬季种植燕麦、小黑麦、黑麦),观测各品种(或组合品种)的适应性、生产性能和种植效果。[结果]鸭茅+多年生黑麦草+白三叶组合品种混播,3年累计鲜草产量(以下均为鲜质量)92796.45 kg/hm^(2)。高羊茅+多年生黑麦草+白三叶、高羊茅+白喜草+白三叶、巨菌草、皇竹草未达到测产标准。轮作模式苏丹草、高丹草未达到测产标准。燕麦太阳神33876.08 kg/hm^(2)、爱沃50145 kg/hm^(2),小黑麦麦丰40020 kg/hm^(2)、麦丰3号28132.5 kg/hm^(2),黑麦24764.25 kg/hm^(2)。[结论]鸭茅+多年生黑麦草+白三叶组合混播适宜种植,但巨菌草、皇竹草不适宜。轮作模式建议夏季休闲,冬季种植燕麦、黑麦、小黑麦。[Objectives]The techniques of planting forage grass under walnut forests were studied and popularized to promote the development of herbivorous animal husbandry in Baoshan City,Yunnan Province.[Methods]The common local varieties of forage grass were selected to design operations of planting forage grass under walnut forests in multiple combinations including mixed planting with perennial variety combina tion(Glomerat Dactylis a L.+Lolium perenne Linn.+Trifolium repens L,Festuca arundinacea Schreb.+Lolium perenne Linn.+Trifolium repens,Festuca arundinacea Schreb.+Paspalum notatum Flugge+Trifolium repens L),monoculture with perennial tall grass(Sorghum Pennisetum×Pennisetum giganteum z.x.lin),1 year and 2 seasons rotation(Sorghum hybrid sudangrass and Sorghum sudanense(Piper)Stapf.in the summer and Avena sativa L.,Triticale,and Secale cereale L.in the winter).The adaptability,production performance,and planting effects of each variety(or combination variety)were identified.[Results]The mixed planting of Dactylis glom erat a L.+Lolium perenne Linn.+Trifolium repens L.resulted in a cumulative fresh weight of 92796.45 kg/hm^(2) over 3 years(hereinafter referred to as fresh weight).The fresh weight of planting Festuca arundinacea Schreb.+Lolium perenne Linn.+Trifolium repens,Festuca arundinacea Schreb.+Paspalum notatum Flugge+Trifo lium repens L.,Pennisetum×sineseand,Pennisetum giganteum z.x.lin did not meet the standards of measuring weight.The fresh weight of the rotation with Sorghum hybrid sudangrass and Sorghum sudanense(Piper)Stapf.did not meet the standards of measuring weight.The fresh weight of Avena sativa L.,Ivor,Triticale,McMuffin,Secale cereale L.was 33876.08,50145,40020,28132.5,24764.25 kg/hm^(2),respectively.[Conclusions]The mixed planting of Dactylis glomerat a L.+Lolium perenne Linn.+Trifolium repens L.is suitable for being planted under walnut forests.The monoculture with Pennisetum×sinese and Pennisetum giganteum z.x.lin is not suitable for being planted under walnut forests.The recommended mode o
