施用不同肥料对紫花苜蓿营养成分的影响

Effect on Nutritional Components with Different Fertilizer Application of Alfalfa

[目的]通过施用不同肥料,提高紫花苜蓿营养品质和饲用价值。[方法]在紫花苜蓿返青期施入3种不同剂量的土壤改良剂和磷钾肥混施、单施磷钾肥、单施土壤改良剂和对照的6个处理,观察不同施肥处理,对比分析不同处理对紫花苜蓿营养成分含量的影响。[结果]各施肥处理相比于对照组,在营养素含量上大部分都有一定的提高,而在非营养素上都有一定的减少。[结论]为紫花苜蓿的生产提供参考依据。

[Objection]The aim was to improve the quality of alfalfa nutrient and feeding value by applying different fertilizers.[Method]Alfalfa root period were put into three different doses of soil conditioners and the effect of nutrient content were analyzed for six processing of phosphorus mixture,the single soil amendment and control fertilization treatments on alfalfa.[Result]Comparing with the fertilization treatments,the contents of nutrients were increasing to a certain extent,but the nutrients were reduced.[Conclusion]The study would provide references for alfalfa production.
