锌肥对玉米作物施用效果研究

Effect of Zinc Fertilizer Application on Maize Crops

为验证锌肥对玉米生长和产量的影响,在弱碱性耕地开展田间对比试验。试验结果表明:施用锌肥对玉米生长具有积极的促进作用,可使玉米秃尖减少、空秆率降低,穗粒质量、千粒质量、产量增加,其中底肥施用ZnSO4·H2O2kg/667m^2效果最好。

In order to verify the effect of zinc fertilizer on maize growth and yield, field comparison test was carried out in weakly alkaline cultivated land. The experimental results showed that: The application of zinc fertilizer had a positive effect on the growth of maize, which could reduce the bald tip, reduce the empty stem rate, increase the grain quality per ear, thousand grain quality and yield, among which the application of base fertilizer ZnSO4.H2O 2 kg/667 m2 had the best effect.
