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800mg/m3,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%。
The trial results showed that Zn、B、Mn fertilizers could promote forage maize growth, enforced resistence and enhance the yield of grain and forage under certain concentrations. Of all three trace elements, 800×10^(-6) was the most suitable concentration for B, which increase LAI by 7.27%, forage yield by 8.42%; 600×10^(-6) was the most suitable concentration for Mn, which increased LAI by 5.36% and forage yield 6.30%; Zn(600×10^(-6))could promote grain production significantly by 9.23%.
