摘要: 锌在不同条件的土壤中,有效性不同,为了进一步掌握锌肥的用量,在玉米上开展了不同锌肥用量田间试验,结果表明,施用锌肥玉米产量明显提高,增施锌肥1kg/667m2,增产效率达75.1 kg,产投比为32∶1,于施锌肥2 kg/667m2。锌肥成本较低,使用方便,建议缺锌地区合理的增施锌肥。

Abstract: The availability of zinc is different in different conditions of soil. In order to further grasp the rate of zinc fertilizer, the experiment was carried out by different rate of zinc fertilizer on corn field. The results showed that :corn yield increased significantly after applying zinc fertilizer;production efficiency increased 75.1 kg after increasing zinc fertilizer application 1 kg/667m^2;the input-output ratio was 32:1, which was higher than the zinc fertilizer application 2 kg/667m^2 ;the zinc fertilizer cost is low and easy to use,so we should increase zinc fertilizer application reasonably for zinc deficiency area.
