| 摘 要： | 麦宾草是高寒地区本土优良牧草,为获得高产、优质的牧草,在青海省祁连县大通河上游高寒草甸区对麦宾草进行了不同刈割时间的试验。经过2年的研究,结果表明:用模糊数学的隶属函数值法,对不同收获期的麦宾草的生长特性、生产性能和营养价值进行综合评价,确定麦宾草的适宜收获期应选择在8月31日到9月15日。

| Abstract: | Elymus tangutorum is a fine native pasture in Alpine region.In order to obtain high yield,high quality forage,the experiments of different cutting time was carried out on Alpine meadow area of Elymus tangutorum in Datong River upstream of Qilian county,Qinghai Province.After two years of study,the results showed that the growth characteristics,production performance and nutritive value of different harvest period of Elymus tangutorum,were evaluated by the membership function method of fuzzy mathematics.It is concluded that the optimum harvest time of Elymus tangutorum is from August 31st to September 15th. |
