不同燕麦品种在南木林县多角乡开展品比试验报告

Report on Comparative Test of Different Oat Varieties in Duojiao Township, Nanmulin County

为了进一步筛选出适宜在日喀则市南木林县多角乡区域种植的优质燕麦(Avena sativa L.)品种,缓解日喀则市冬季饲草紧张的局面,减少天然草原的压力,实施不同燕麦品种在南木林县的品比试验。试验通过种植“甜燕麦”“加燕2号”“青引1号”“青引2号”“青海444”“白燕2号”等6个燕麦品种,以“青海444”作为对照,分别观测了物候期、农艺性状和产草量等指标。通过试验结果表明,对照品种青海444生育期最短,最早进入成熟期,“青引1号”株高显著高于对照品种(p<0.05),“青引2号”和“加燕2号”地上部分长势显著优于对照品种(p<0.05),“甜燕麦”“白燕2号”“加燕2号”的根系长势均优于对照品种(p<0.05)。通过品比后,以高产量为目的,在该区域种植推荐顺序为:“加燕2号”“白燕2号”“青引2号”“青海444”“青引1号”“甜燕麦”。以追求品质为目的,在该区域推荐顺序为:“青引1号”“青海444”“加燕2号”“甜燕麦”“白燕2号”“青引2号”。收获籽粒为目的,可推广“青海444”品种。

In order to select suitable and superior oat varieties(Avena sativa L.)in Dujiao Township, Nanmulin County, Shigatse, ease the feed shortage in Shigatse, reduce pressure of natural grassland, the comparative test of different Oat varieties in Duojiao township were carried out. By Planting six oat varieties, including‘Sweet Oat’‘Jiayan No.2’‘Qingyin No.1’‘Qingyin No.2’‘Qinghai 444’‘Baiyan No.2’and‘Qinghai 444’used as the control. The phenological period, agronomic characters and grass yield were observed. The results showed that Control variety‘Qinghai 444’has the shortest growth period and the earliest maturity. The plant height of‘Qingyin No.1’was significantly higher than that of the control variety(p<0.05).The aboveground growth of‘Qingyin No.2’and‘Jiayan No.2’was significantly better than that of the control variety(p<0.05). The root growth of‘Sweet oat’‘Baiyan No.2’and‘Jiayan No. 2’was better than that of the control varieties(p<0.05). After comparison among varieties, For High Yield,the recommended order is‘Jiayan No.2’‘Baiyan No.2’‘Qingyin No.2’‘Qinghai 444’‘Qingyin No.1’‘Sweet Oat. For Quality, the recommended order is Qingyin No.1’‘Qinghai 444’‘jiayan No.2’‘Sweet Oat.’‘baiyan NO.2’‘Qingyin No.2.’For the purpose of harvesting seeds,‘Qinghai 444’was recommended.
