摘要： Zn、B、Mn三种微肥在一定浓度下能够促进饲料玉米生长，增强玉米的抗性、提高饲草和果实的产量。其中，B肥的有效浓度为800×10-6，能够提高叶面积指数7.27%，鲜草产量8.40%；Mn肥的有效浓度为600×10-6，能够提高叶面积指数5.36%，提高饲草产量6.30%；Zn肥的最佳浓度为600×10-6，能够提高果实产量9.23%。

Abstract: The trial results showed that Zn、B、Mn fertilizers could promote forage maize growth, enforced resistance and enhance the yield of grain and forage under certain concentrations. Of all three trace elements, 800×10-6 is most suitable to B which can increase LAI by 7.27% forage yield by 8.42%; 600×10-6 is most suitable to Mn which can increase LAI by 5.36% and forage yield 6.30%; Zn（600×10-6）can promote grain production significantly by 9.23%.
