12个多年生牧草品种在迪庆高寒地区的引种评价

为筛选出适宜云南迪庆高寒地区种植的多年生牧草品种,本研究开展了12个多年生牧草品种引种适应性的比较,并采用灰色关联度综合评价法对其生产性能进行了综合评价。结果表明,12种牧草生产性能的高低顺序为紫花苜蓿牧歌401+Z(Medicago sativa cv.Amerigraze401+Z)菊苣将军(Cichorium intybus cv.Commander)鸭茅安巴(Dactylis glomerata cv.Anmba)多年生黑麦草雅晴(Lolium perenne cv.Yatsyn)白三叶铺地(Trifolium repens cv.Prop)红三叶(T.pratense)白三叶海法(T.repens cv.Haifa)紫花苜蓿游客(Medicago sativacv.Eureka)紫花苜蓿WL-525(Medicago sativacv.WL-525)扁穗雀麦草地麦特(Bromus catharticus cv.Grasslands Matua)紫花苜蓿猎人河(M.sativacv.Hunterriver)老芒麦同德(Elymus sibiricus cv.Tongde)。其中,牧歌401+Z紫花苜蓿、将军菊苣、安巴鸭茅、雅晴多年生黑麦草、铺地白三叶、普通红三叶、海法白三叶在当地适应性较好,生产性能相对较高,可作为当地建植栽培草地及改良天然草地的优选品种。研究结果对解决当地饲草匮乏、促进当地草地畜牧业的可持续发展具有重要的意义。

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.
