摘要
根据调查,目前多数地区土壤中锌元素严重贫乏,影响了作物单位面积产量的提高和抗病性.为进一步挖掘土壤潜力,提高单位面积产量和抗病性,改善品质,探讨出了在土壤有效锌含量不足0.5ppm的情况下补施锌微肥增产效果明显,并且增强玉米的抗病性.
According to investigate, the element zinc is very poor in soil of most area at present, which has affected crops to raise the per unit yield their disease resistance. In crder to tap the latent power of soil deeply, raise the per unit yield and their disease resistance, improve crops' vanity, the method of applying microelemental fertilizer of zinc has been approached in the condition of soil with the effective zinc content less than 0.5ppm, it has gotten obvious results of increasing production and built up con's disease resistance.
