奇台无芒雀麦区域试验

Regional Test of Qitai Smooth Brome Grass

于1988年至1990年,分别在乌鲁木齐市老满城、奇台县、阿勒泰市蒙库、昭苏县和天山北坡中山带谢家沟进行了奇台无芒雀麦品种区域试验。试验结果表明奇台无芒雀麦可以在北疆很大的地区(从海拔670m的平原荒漠到海拔1900m的中山带)生长,每年可以刈草1～2次,甚至3次,其产草量极显著地高于对照品种——生产利用的老芒麦。方差分析结果表明与其它供试材料相比,奇台无芒雀麦的品种丰产性好,稳定性最高,在草场改良中用奇台无芒雀麦取代老芒麦的策略是正确的。

During 1988 and 1990, the regional terts of Qitai smooth brome grass (Bromus inermis Leyss.) were Conducted in Lao mancheng of Urumqi city, Qitai county, Mengku area of Altay city,Zhaoshu county and Xeja valley in the medium-mountain area on the northern slop of Tianshan mountain respectively. The results showed that Qitai cultivar could grow in a large area in the northern Xinjiang, from plain desert with a elevation of 670 m to the medium-mountain areas (1900 m). It could be cut 1-2 times or 3 times per year for hay production and the forage yields of Qitai were considerably significantly higher than the ck cultivar, Siberian wildrye grass which was being used in those areas for pasture improvement. The variant analysis indicated that the productivity of Qitai was high and its varietal stability was the highest compared with the others and it was a correct tactics to change the Siberian wildrye grass cullivar with Qitai smooth brome grass in pasture improvement.
