青海东部农区高产优质燕麦品种筛选

为筛选出适宜青海东部农区种植的优质燕麦(Avena sativa)品种,以8个当地主栽燕麦品种为供试材料,对其农艺性状、产量和品质进行比较分析,并利用隶属函数法进行综合评价。结果表明,开花期8个燕麦品种的饲草产量及品质从高到低依次为青海444>青海甜燕麦>青燕1号>青引1号>加燕2号>白燕7号>青引2号>林纳,其中青海444饲草产量最高,达39091.29 kg·hm^-2,青海甜燕麦排名第2,且两者纤维含量低,适口性较好;青燕1号饲草产量、粗蛋白含量较高。因此收获饲草建议种植青海444、青海甜燕麦和青燕1号。成熟期8个燕麦品种的种子产量及饲草品质综合评价从高到低依次为白燕7号>青海甜燕麦>青燕1号>林纳>青海444>青引2号>加燕2号>青引1号,白燕7号粗蛋白含量(3.74%)最高,但白燕7号的种子产量(5528.01 kg·hm^-2)低于林纳(5888.69 kg·hm^-2),青燕1号种子产量较低,因此以种子高产为目的建议种植白燕7号、青海甜燕麦和林纳。

Selection of high-yield and good-quality oat varieties in the eastern agricultural area of Qinghai Province

To select good-quality oat varieties suitable for planting in the eastern agricultural area of Qinghai Province,eight local main oat varieties were studied.The agronomic characteristics,yield,and quality of the tested varieties were analyzed and compared,and their adaptability is evaluated by membership function.The results showed that the forage yield and quality of the eight oat varieties in the flowering stage were as follows from high to low:Qinghai 444>Qinghai Sweet oat>Qingyan No.1>Qingyin No.1>Jiayan No.2>Baiyan No.7>Qingyin No.2>Lena.The grass yield of Qinghai 444 was the highest at 39091.29 kg·ha^-1,whereas Qinghai Sweet oat ranked the second,and they both have low fiber content,which led to better palatability.The grass yield and crude protein content of Qingyan No.1 were higher than those of the other tested varieties.Therefore,it is suggested to plant Qinghai 444,Qinghai Sweet oat,and Qingyan No.1 for harvesting forage.The order of the eight oat varieties in terms of seed yield and forage quality were as follows from high to low:Baiyan No.7>Qinghai Sweet oat>Qingyan No.1>Lena>Qinghai 444>Qingyin No.2>Jiayan No.2>Qingyin No.1.The crude protein content(3.74%)of Baiyan No.7 was the highest,but its seed yield(5528.01 kg·ha^-1)was lower than that of Lena(5888.69 kg·ha^-1).The seed yield of Qingyan No.1 was low.Thus,it is suggested to plant Baiyan No.7,Qinghai Sweet oat,and Lena for high seed yield.
