为了筛选出适宜阿克苏地区林果间作的饲草品种,以期为农、林、牧协调发展提供理论依据,试验在枣林下种植四个高秋眠级苜蓿品种WL712、WL903、WL525HQ、WL656HQ,并对四个苜蓿品种进行了生产性能和营养品质的测定。结果表明:WL525HQ四茬总鲜草产量最高,显著高于另三个品种(P<0.05);WL656HQ四茬总干草产量最高,与WL903差异不显著(P>0.05),显著高于WL525HQ、WL712(P<0.05),WL712最低;粗蛋白含量以WL525HQ较高,中性洗涤纤维、酸性洗涤纤维含量以WL525HQ较低;选择干草产量、粗蛋白产量、酸性洗涤纤维、中性洗涤纤维、粗蛋白含量和相对饲喂价值作为综合评价四个紫花苜蓿品种优劣的指标,紫花苜蓿WL525HQ关联度值最大,其他依次是WL903、WL656HQ、WL712。
In order to screen the forage varieties suitable for intercropping in Aksu region, in order to provide a theoretical basis for the coordinated development of agriculture, forestry and animal husbandry, we planted four high-fall dormancy alfalfa varieties WL712, WL903, WL525HQ and WL656HQ in jujube forest, A variety of alfalfa for performance and nutritional quality determination. The results showed that the total fresh grass yield of WL525HQ was highest, significantly higher than that of the other three cultivars (P <0.05); WL656HQ had the highest total hay yield and no significant difference with WL903 (P> 0.05), but significantly higher than that of WL525HQ and WL712 (P <0.05), WL712 was the lowest, WL525HQ was the highest content of crude protein, WL525HQ was low for neutral detergent fiber and acid detergent fiber, and hay yield, crude protein yield, acid detergent fiber, neutral detergent fiber and crude protein Content and Relative Feeding Value As the index of comprehensive evaluation of four alfalfa varieties, alfalfa WL525HQ had the highest correlation value, followed by WL903, WL656HQ and WL712.
