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 A5 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.
