摘要: 为解决青海省环湖地区饲草资源与种植方式相对单一的现状,本研究在青海省海北州开展了小黑麦(×Triticosecale Wittmack)与饲用型豌豆(Pisum sativum)同行混播处理下饲草生产性能与营养品质的差异分析,并利用隶属函数法综合评价得出该地区最适混播比例,以期为高寒地区饲草生产提质增效提供科学依据和理论支撑。结果表明:在供试的7个混播处理中,混播处理150 kg·hm-2小黑麦+60 kg·hm-2饲用型豌豆处理的干草产量最高,达12 307 kg·hm-2;混播处理120 kg·hm-2小黑麦+ 72 kg·hm-2饲用型豌豆与60 kg·hm-2小黑麦+ 96 kg·hm-2饲用型豌豆处理的粗蛋白含量较高。最后根据隶属函数值综合评价得出小黑麦与饲用豌豆最佳混播播量为180 kg·hm-2小黑麦+ 48 kg·hm-2饲用型豌豆,其次是150 kg·hm-2小黑麦+60 kg·hm-2饲用型豌豆。

Abstract: In order to solve the shortage of forage resources and relatively simple planting methods in the areas around the lake in Qinghai Province. In Haibei Prefecture, Qinghai Province, differences of forage performance and nutritional quality between triticale (×Triticosecale Wittmack) and pea (Pisum sativum) were analyzed. After that, the membership function method was used to comprehensively evaluate the optimal mixed-sowing ratio in this area, in order to provide a scientific basis and theoretical support for improving the quality and efficiency of forage production in alpine and cold regions. The results showed that among the seven mixed sowing treatments, the hay yield of triticale 150 kg·hm-2 and pea 60 kg·hm-2 was the highest, up to 12 307 kg·hm-2. Comparison of nutritional quality showed that hay crude protein content of mixed sowing of triticale 120 kg·hm-2 with pea 72 kg·hm-2, and mixed sowing of triticale 60 kg·hm-2 with pea 96 kg·hm-2 were higher. The optimum mixture of triticale and pea in the experimental area was 180 kg·hm-2 of triticale with 48 kg·hm-2 of pea, followed by 150 kg·hm-2 of triticale and 60 kg·hm-2 of pea.
