高寒地区几种燕麦品种生产特性比较

在青海大通县对10种高产燕麦Avena sativa品种的物候特性、茎叶比、牧草产量和粗蛋白含量以及种子产量进行了比较研究。结果表明：10种燕麦品种生育期短，均可在青海大通地区种植。青海444、加拿大栽培燕麦和LENA的穗长、小穗轮数、小穗数、籽粒数和种子产量均高于其它品种，适宜建立种子田；青海甜燕麦、青引2号和青引1号的牧草产量和蛋白含量高，叶量丰富，饲草性状好，适宜建立饲草田。

Comparison of productive characteristics of Avena sativa varieties in alpine region

Growth characteristics,stem-leaf ratio,biomass,crude protein and grain yield ten varieties of Avena sativa were studied in Datong County,Qinghai Province.The results indicated that ten varieties have short growing stages and could grow in Datong Region.The panicle length,rings and number of spikelet,and grain number and yield of Qinghai 444,Canada cultivar and LENA were higher than other varieties and were suitable for seed production.The crude protein and biomass of Qinghai sweet,Qingyin No.1 and Qingyin No.2 were higher than other varieties and good for hay production.
