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

| Abstract: | Based on soil conditions in Henan province,physiologic characters and existing problems in grass production,many application studies about two trace element fertilizers(Zn and Mn)in alfalfa grassland were conducted in this paper,and analyzed the rates and methods of application.The results showed that effective applying concentration ranged from 400 to 500 mg/kg and the optimum concentration was 430 mg/kg.Combined application of Zen(430 mg/kg)and Mn(380 mg/kg)had better productive effects which enhanced forage yield by 10.7%,seed yield by 10.7%. |
