摘要: 为确定小黑麦(× Triticosecale Wittmack)品种‘藏饲3号’在西藏牧区的生产性能及适宜种植区域,试验以小黑麦品种‘藏饲1号’和‘甘农2号’为对照,于2022和2023年,研究了‘藏饲3号’在南木林、达孜和拉孜试验点的株高、分蘖数、鲜草产量和干草产量。结果表明:从年份看,2023年3个试验点3个小黑麦品种的平均干草产量显著高于2022年(P<0.05),但平均株高、分蘖数和鲜草产量均无显著差异;从试验点看,南木林试验点2年3个小黑麦品种的平均株高、鲜草产量和干草产量均显著高于达孜和拉孜试验点(P<0.05),拉孜试验点的平均分蘖数显著最高(P<0.05);从年份×试验点×品种的差异来看,2022年南木林试验点‘藏饲3号’的鲜草产量(52.80 t·hm-2)显著高于其他品种(P<0.05),2023年该品种的干草产量最高,为19.08 t·hm-2,显著高于对照品种(P<0.05)。从综合评价看,南木林试验点‘藏饲3号’在2022和2023年综合评价值均最高,其生产性能表现最好。综上,‘藏饲3号’饲草生产性能优于‘藏饲1号’和‘甘农2号’,适宜在南木林试验点以及与其相似气候区域推广种植。

Abstract: To determine the production performance and suitable planting area of triticale (× Triticosecale Wittmack) variety ‘Zangsi No.3’ in Xizang pastoral area, the plant height, tiller number, fresh yield and hay yield of ‘Zangsi No.3’ in Namling, Dagzê and Lazi experimental sites were studied in 2022 and 2023, with triticale varieties ‘Zangsi No.1’ and ‘Gannong No.2’ as controls. The results showed that the average hay yield of three triticale varieties in 2023 was significantly higher than that in 2022 (P<0.05), but there were no significant difference in average plant height, tiller number and fresh yield. From the experimental sites of view, the average plant height, fresh yield and hay yield of the three triticale varieties in Namling experimental site were significantly higher than those in Dagzê and Lazi experimental sites (P<0.05), and the average tiller number in Lazi experimental site was the highest (P<0.05). From the difference of years×experimental sites×varieties, the fresh yield (52.80 t·hm-2) of ‘Zangsi No.3’ in Namling experimental site in 2022 was significantly higher than other varieties (P<0.05), and the hay yield of this variety was the highest in 2023, 19.08 t·hm-2, significantly higher than the control varieties (P<0.05). From the comprehensive evaluation, the comprehensive evaluation value of ‘Zangsi No.3’ in Namling experimental site was the highest in 2022 and 2023, and its production performance was the best. In summary, the production performance of ‘Zangsi No.3’ was better than ‘Zangsi No.1’ and ‘Gannong No.2’, which was suitable for planting in Namling experimental site and other similar climate area.
