喀什地区9个紫花苜蓿品种生产性能和营养品质评价与分析OA

Alfalfa is one of the high-quality forage grasses widely cultivated in the Kashgar region.The adaptability and high-yield potential of its cultivars are crucial for the local agriculture and animal husbandry.However,Alfalfa cultivation in this area faces significant challenges,including a heavy reliance on imported seeds and a lack of systematic research on local varieties.In order to screen high-yield and high-quality Alfalfa varieties suitable for planting in this area,nine Alfalfa varieties at home and abroad were used as materials in this experiment.The yield and nutritional value traits were analyzed and evaluated by variance analysis,correlation analysis and comprehensive evaluation of membership function values.The results showed extremely significant difference in hay yield between the first and third stubbles(P＜0.01),and the annual total hay yield of WL363 HQ,Gannong No.5 and Jinneng No.5030 was the highest.There was no significant correlation was observed between plant height and yield.The crude protein content of Zhongmu No.1,Xinmu No.4 and Saiwo 5 was significantly higher than that of other varieties(P＜0.0l).There was a significant positive correlation between acid detergent fiber and neutral detergent fiber.There was a significant negative correlation between acid detergent fiber and crude ash and crude protein.The feeding value of Xinmu No.4 was significantly higher than that of other varieties,reaching 188.77.Through the comprehensive evaluation of membership function values,Gannong No.5,Zhongmu No.1 and WL343HQ had better comprehensive performance and could be recommended for demonstration and large-scale promotion in the Kashgar region.
