摘要/Abstract

摘要： 为了研究6个披碱草属牧草品种(野生披碱草、同德老芒麦优良株系、红原老芒麦、青牧1号老芒麦、同德短芒披碱草、同德老芒麦)在高海拔地区的适应性,在青海省海晏县对这6个披碱草属牧草品种进行了试种,并对其植株高度、产草量、干鲜比、茎叶比进行了研究。结果表明,同德老芒麦、红原老芒麦的初花期株高、鲜草产量表现较好,这说明同德老芒麦明显优于其他品种;红原老芒麦鲜草产量指标表现优异,待进一步区域试验后可推广利用。

Abstract: In order to investigate the adaptability of six varieties of Elymus forage in high altitude area,including wild Elymus dahuricus Turcz.,Elymus sibiricus L.cv.Tongde,excellent lines of Elymus sibiricus L.cv.Tongde,Elymus sibiricus L.cv.Hongyuan,Elymus sibiricus L.cv.Qingmu No.1 and Elymus breviaristatus Keng cv.Tongde,the trial planting were designed and conducted at Haiyan County of Qinghai Province.Furthermore,the plant height,grass yield,fresh/dry weight ratio and stem/leaf ratio of the six selected varieties of Elymus forage were determined and compared.The results showed that the varieties of Elymus sibiricus L.cv.Tongde and Elymus sibiricus L.cv.Hongyuan had higher plant height at initial flowering stage;Elymus sibiricus L.cv.Hongyuan exhibited higher fresh grass yield,indicating this variety could be promoted and utilized after further regional test.
