Adaptability evaluation of 12 perennial forage cultivars in alpine region of Diqing
To select suitable perennial forages cultivating in alpine region of Diqing,the introduction adaptabili-ty of 1 2 perennial forage grasses was studied in this research,and the grey correlative degree analysis was used to evaluate the production performance of these 1 2 perennial forage grasses.The results showed that the order of production performance of 12 perennial forage grasses was Medicago sativa cv.Amerigraze401+Z >Cicho-rium intybus cv.Commander > Dactylis glomerata cv.Anmba > Lolium perenne cv.Yatsyn > Trifolium repens cv.Prop > Trifolium pratense > T.repens cv.Haifa > M.sativa cv.Eureka > M.sativa cv. WL-525 >Bromus willdenowii cv.Grasslands Matua >M.sativa cv.Hunterriver >Elymus sibiricus cv. Tongde.The production and adaptability of M.sativa cv.Amerigraze401+Z,Cichorium intybus cv.Com-mander,D.glomerata cv.Anmba,L.perenne cv.Yatsyn,T.repens cv.Prop,T.pretense and T.repens cv. Haifa were relatively better,which were preferred varieties used in establishing artificial grassland and modif-ying natural grassland in Diqing area.The results of this research play an important role in solving the forage shortage and promoting the sustainable development of local grassland animal husbandry.
