川西北高原20个燕麦品种农艺性状、营养品质及干草质量综合评价
Comprehensive Evaluation of Agronomic Traits,Nutritional Quality,and Hay Quality of 20 Oat Varieties in the Northwestern Sichuan Plateau
摘要
Abstract
[Objective]To screen high-yielding,high-quality oat varieties suitable for green hay making in the highlands of northwest Sichuan,thereby promoting sustainable development of regional animal hus-bandry.[Method]Twenty forage oat varieties were evaluated in Hongyuan County through comparative trials and green hay processing studies.Agronomic traits,nutritional quality,moisture content,and dry-ing rate were measured,with comprehensive evaluation conducted using principal component analysis and membership function analysis.[Result]In variety comparison:Dayameng and Regent both ex-ceeded 140 cm in plant height,while Fuxing yielded the highest hay production(13 370.57 kg/hm2),both significantly higher than other varieties;Haiwei had the highest crude protein content(8.79%),while Regent King had the highest soluble carbohydrate content(39.01 mg/g).Menglong exhibited the highest total digestible nutrients(61.88)and relative feeding value(127.21).In hay evaluation:Aba Oats exhibited the fastest moisture loss,reaching 25.94%moisture content by 30 hours.Its ADF and NDF contents were significantly lower than other varieties(P<0.05),while it possessed the highest total digestible nutrients.[Conclusion]Based on membership function and TOPSIS comprehensive evalua-tions,Tek,Challenger,and Aba oats are suitable for cultivation on the plateau in northwest Sichuan.Among these,Aba oats are particularly well-suited for processing into green hay.关键词
