摘要： 针对河南省气候土壤特点、锌锰钼肥的生理功能以及牧草生产利用中存在的问题，对Zn、Mn两种微肥在紫花苜蓿（Medicago sativa L.）优质牧草生产中的配施技术进行了研究。结果表明：紫花苜蓿的有效范围为400~500mg/kg，最佳浓度为430mg/kg。430mg/kg的Zn肥与380mg/kg的Mn 肥结合使用，效果更好，可使牧草产量提高约10.7%，种子产量提高13.7%。

Abstract: Based on the climate and soil conditions of Henan province，the physiologic functions of Zn and Mn and the existing problem of alfalfa（Medicago sativa L.）production，this paper studied the responses to the coordinate use of two trace element fertilizers（Zn and Mn）in alfalfa grassland，and analyzed the applied range and concrete measures. The results showed that effective applied concentration ranged from 400mg/kg to 500 mg/kg with the optimum concentration being 430mg/kg. Coordinate use of Zn（430mg/kg）and Mn（380mg/kg）could increase the forage yield by 10.7% and the seed yield by 13.7%, respectively, showed a better productive effect.
