摘　　要：试验旨在探究不同氮肥种类对南疆地区苜蓿生长性状及品质性状的影响。试验以2个紫花苜蓿品种(WL366和佰苜401)为材料,设置不同氮肥处理组,即对照组(CK)、尿素组(UR)、尿素硝铵溶液组(UAN)及40多态氮肥组(40)。试验测定不同氮肥施用后的紫花苜蓿生产性能和品质性状,运用隶属函数分析,对不同氮肥种类施用效果进行综合评价。结果显示,施肥对紫花苜蓿产量和株高有一定影响,并且能够提高紫花苜蓿的相对饲喂价值。苜蓿品质综合表现为UAN>40>UR>CK,40多态氮施肥能够明显增加紫花苜蓿的产量和株高。研究表明,40多态氮肥对南疆地区苜蓿产量与品质综合提升效果最佳。The purpose of the study was to explore the effects of different nitrogen fertilizer types on alfalfa growth traits and quality traits in southern Xinjiang.In this study,two alfalfa varieties(WL366 and Baimu 401) were used as materials,and different nitrogen fertilizer treatment groups were set up,namely control group(CK),urea group(UR),urea ammonium nitrate solution group(UAN),and 40 polymorphic nitrogen fertilizer group(40).The performance and quality characters of alfalfa after different nitrogen fertilizer application were determined.The application effect of different nitrogen fertilizer types was comprehensively evaluated by membership function analysis.The results showed that fertilization had a certain effect on yield and plant height of alfalfa,and could increase the relative feeding value of alfalfa.The comprehensive performance of alfalfa quality was UAN >40> UR > CK,and 40 polymorphic nitrogen fertilization could significantly increase the yield and plant height of alfalfa.The study indicates that 40 polymorphic nitrogen fertilizer has the best effect on the comprehensive improvement of alfalfa yield and quality in southern Xinjiang.
