| 摘 要： | 采用土壤养分状况系统研究法对江苏盐城大丰市方强农场的土壤进行了研究。土壤养分分析结果表明:该地区土壤中磷、钾丰富,碱解氮缺乏,微量元素锌、锰缺乏,铁、铜含量丰富。吸附试验的结果表明:供试土壤对钾、锌、锰、铜的吸附强,对磷的吸附较弱。盆栽试验结果表明:水稻高产的土壤养分主要限制因子是锰、锌,其次是铜、氮。

| Abstract: | The soil nutrient of Fangqiang Farm in Yangcheng,Jiangsu was studied through adopting the systematic research method.The results showed that P and K were rich,alkaline hydrolytic nitrogen,microelements Mn and Zn were deficient here,while Fe and Cu were rich.Nutrient adsorption experiment showed that the tested soil had strong adsorption to K,Zn,Mn and Cu,while weak adsorption to P.Pot culture experiment showed that the major limiting factors of soil nutrient were Mn and Zn in rice high-yielding production,followed by Cu and N. |
