青海高原农牧交错带上7种燕麦生产性能及营养品质综合评价
Comprehensive evaluation on production performance and nutritional quality of seven Avena sativa species in agro-pastoral ecotone of Qinghai Plateau
摘要
Abstract
The experiment was to screen suitable Avena sativa varieties for cultivation in the agricultural pastoral ecotone of the Qinghai Plateau.Field observations were conducted in Riyue Township,Huangyuan County,a typical agricultural pastoral ecotone of the Qinghai Plateau.A comprehensive evaluation was conducted on seven Avena sativa materials considering aspects such as production performance,nutrient composition and effective nutrient output.The results showed that Avena sativa varieties with different milk ripening stages had significant differences in the same ecological environment.The hay yield of Qingyin No.1 and Qingtian No.1 significantly higher than that of other varieties(P<0.05).The crude protein(CP)content of Mengsiyan No.1 reached up to 10.01%.The net protein utilization rate of Qingyin No.3 was the highest,reaching 58.55%,followed by Qingtian No.1 and Qingyin No.1.The metabolic energy and metabolic energy output of Qingyin No.1 were the highest,reaching 10.21 MJ/kg and 10 429.35 kg/hm2,respectively,with significant differences compared to other varieties(P<0.05).The CP output per unit area and net protein output of Qingtian No.1 were the highest,reaching 1 468.98 and 774.89 kg/hm2,respectively,with significant differences compared to other varieties(P<0.05).The experiment indicates that based on a comprehensive evaluation of dry matter output,net protein output,and metabolic energy output,it is recommended to plant varieties Qingtian No.1 and Qingyin No.1 in this area.关键词
