摘要
Abstract
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.关键词
