不同氮肥对南疆地区苜蓿饲草产量与品质的影响
Effects of different nitrogen fertilizers on alfalfa forage yield and quality in southern Xinjiang
摘要
Abstract
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.关键词
