当雄山南燕麦栽培试验比较研究

燕麦作为高寒牧区一年生人工草地的主要饲料作物，其产草量高、品质好、抗逆性强，在畜牧业发展中具有举足轻重的作用，是高寒牧区枯草季节的主要饲草来源。但是在西藏，燕麦的生产一直处于较为落后的状态。试验采集了西藏两个地区的燕麦种子进行种植，并对其植物学性状、物候期、发芽率、生长高度、地上部分生物量以及营养成份进行比较和分析，发现燕麦生长性能好、产量高、营养价值丰富，是一种优质牧草，可在高寒牧区大面积种植推广，这对西藏高寒地区畜牧业发展、农牧民增收、生态环境保护均具有重要意义。

~esearch on Comparative Cultivation Experiment of A vena sativa from Dhamshong and Lhukar

Avena sativa as a main annual forage crop in alpine areas, it plays an important role in development of animal husbandry with its high yield, good quality and strong resistance and it become the main alpine forage sources during the hay season. However, the production of Avena sativa has been in a relatively backward state in Tibet. Avena sativa seeds were collected from two regions in Tibet and its botanical characters, phenology, germination, growth height, aboveground biomass and nutrients were analyzed comparatively. The results showed that Avena sativa is high quality forage with its well growth performance, high yield and rich in nutritional value, and can be planted in large areas of alpine pastoral promotion. This has an important means for the development of livestock in alpine region, increasing income of farmers and herdsmen, and ecoenvironmental protection.
