摘要
甘引1号黑麦是针对高海拔寒冷地区选育而成的栽培牧草品种.为评价甘引1号黑麦对高寒气候条件的适应性,2010-2011年在甘肃青藏高原区、祁连山区和黄土高原区等不同生态区域进行了甘引1号黑麦生长特性及生产性能的比较研究.结果表明:甘引1号黑麦适宜在青藏高原区和祁连山区等高海拔寒冷地区栽培,不仅抗寒耐湿,青绿期长,且生长速度快,产草量高.在不同生态区域乳熟期平均株高较当地燕麦高35.49％,肃南、天祝、岷县和合作试验点青干草产量分别较当地燕麦增产31.52％、44.59％、34.03％和31.48％,且青藏高原区和祁连山区4个试验点鲜、干草产量显著高于黄土高原区的兰州点.说明甘引1号黑麦在海拔2 400～2 800 m地区栽培更为适宜.
Abstract
Secale cereale L.‘Ganyin No.1’ is a cultivated forage variety bred for high altitude cold region.In order to evaluate its adaptability to cold climate conditions and cultivation regions,its growth characteristics and production performance in Tibetan plateau,Qilian Mountain area and Loess Plateau area in Gansu were compared.The results showed that Secale cereale L.‘ Ganyin No.1’ was suitable to plant in Tibetan plateau and Qilian Mountain area with high resistance to cold and wet,long greenish period,fast growth and high yield;compared with local oats in different ecological area,the average height of Secale cereale L.‘Ganyin No.1’ increased by 35.49％,and the hay yields in Sunan,Tianzhu,Minxian and Hezuo exploratory point,increased by 31.52％,44.59％,34.03％ and 31.48％ respectively.The fresh and hay yield were significantly higher in Tibetan Plateau,Qilian Mountain area than that in Loess Plateau area.It was concluded that the seed production of Secale cereale L.‘Ganyin No.1’ were more suitable in the Gansu area at the altitude of 2 400-2 800 meters.
