为提高香格里拉高寒地区饲草生产能力,在小中甸镇开展了牧草混播组合试验.试验设5个混播组合(A1、A2、A3、A4、A5),随机区组设计,连续两年对牧草产量和组分进行测定,第2年取混合样对营养含量进行分析.结果表明,A1和A5组合牧草产量显著高于A2、A3和A4 (P＜0.05);A3、A1、A5年度间群落组分变化不大,稳定性较强;A2、A4、A5的粗蛋白含量较高,均超过24％.3项指标综合考虑,A1[安巴鸭茅(Dactylis glomerata cv.Anmba)+草地休衣白三叶(Trifolium repens cv.Grasslands huia)+红三叶(T.pratense)]和A5[安巴鸭茅+雅晴多年生黑麦草(Lolium perenne cv.Yatsyn)+海法白三叶(T.repens cv.Haifa)+普纳菊苣(Cichorium intybus cv.Puna)]适宜在香格里拉高寒地区种植应用.
Screening of the pasture mixed sowing combination in Shangri-la alpine region of Yunnan
In order to improve the forage production capacity in Shangri-la alpine region,we carried out mixed sowing combination experiment in Xiaozhongdian Town.The experiment set five mixed sowing combination (A1,A2,A3,A4,A5) using randomized blocks design to measure hay yield and their component in consecutive two year and analyze the nutrient content of mixed sample in the second year.The results showed that A1 and As hay yield significantly higher than that of A2,A3 and A4 (P＜0.01);community composition of A3,A1,A5 had strong stability with little change between two years;crude protein content of A2,A4 and A5 was higher (＞24％).Based on the performance of three index,A1 (Dactylis glomerata cv.Anmba+ Trifolium repens cv.Grasslands huia+T.pratense) and A5 (D.glomerata cv.Anmba+Lolium perenne cv.Yatsyn+T.repens cv.Haifa+Cichorium intybus cv.Puna) were suitable for sowing application in Shangri-la alpine region.
