摘要
在天祝高寒地区,通过研究7个燕麦品种的株高、鲜干比、叶面积指数、产草量、种子产量等性状,筛选出生产性能优良的品种。结果表明:供试品种对当地的适应性均较好,大部分属于中、晚熟型,少部分属于极晚熟型,且在天祝高寒地区均能完成生育期。灌浆期坝莜3号和甜燕麦的产草量显著高于其它品种(p<0.05),其干草产量分别为10 511.38kg/hm2和9 261.12kg/hm2。晋燕9号干草产量最低,为4 622.31kg/hm2。在天祝高寒地区由于海拔高,昼夜温差大,光合作用强,种子产量较高,供试燕麦品种中,白燕7号、丹麦444和甜燕麦的表现较好,是进行高产田的首选品种。
In Tianzhu alpine area, varieties with excellent production performance were picked by studying plant height, fresh-dry ratio, leaf area index, grass production, and seed yield of 7 oat varieties. The results showed that tested varieties had good adaptability to the local area, most of them belonged to the middle and late maturity type, and a few belonged to the ex- tremely late-maturing type, and were able to complete a whole growth period in Tianzhu alpine area. The grass production of oat varieties in such as Bayou No 3 and Sweet oat were higher than others significantly（p〈0.05）, the dry yield were 10511.38 kg/hm2 and 9261.12 kg/hm2 respectively. Baiyan No 2 had the lowest yield of dry grass, which were 4622. 31 kg/hm2. In Tianzhu alpine region of China. because of high elevation and temperature difference between day and night, the photosynthesis enhanced, the seed yield is higher. Consequently, it can be coneluded that Baiyan No 7, Denmark 444 and Sweet oat showed good productive characters and were. the target varieties used for grassland with high productivity.
