通过田间试验，研究了松嫩平原黑土和黑钙土锌肥的有效施用条件与玉米产量的关系。结果表明：在pH＞7.2、石灰含量＞3.9%、砂粒含量＞40%、代换量＜15cmol/kg、有机质含量＜20g/kg及土壤有效锌含量低于缺锌临界值0.8mg/kg的土壤条件下，施用锌肥具有明显的增产效果。在高磷情况下会降低土壤锌的有效性，易加重玉米缺锌。玉米品种试验表明：“吉单101”、“四单8”等玉米品种对缺锌最为敏感，施锌效果显著。

The relationship between the effective application of Zn fertilizer and the yield of maize grown in was studied through pot and field experiments in phaiozem and chernozem in Songnen Plain. The results showed that the yield of maize was significantly increased with the application of zinc fertilizer under such soil conditions as pH＞7.2, the content of CaCO3＞3.9%, the content of sand＞40%, CEC＜15cmol/kg, content of organic matter＜20g/kg and content of available Zn＜ 0.8mg/kg (critical value). High content of phosphorous decreased availability of zinc and thus aggravated Zn deficiency of maize. Of all the varieties tested, “Jidan 101” and “Sidan 8” were most sensitive to Zn deficiency and most responsive to the application of Zn fertilizer.
