宽甸县新增蔬菜保护地土壤养分状况及提高土壤肥力途径

The Nutrient Conditions of Newly Increased Protective Field in Kuandian County and the Way of Increasing Soil Fertility

宽甸县新增蔬菜保护地(2004—2007年)土壤养分含量状况检测结果表明:保护地土壤有机质和碱解氮平均含量处于中等水平,土壤有效磷含量较低,保护地土壤pH值<5.5的酸性土壤面积占新增面积的23.5%。根据检测结果提出了提高保护地土壤肥力的施肥措施。

The resuhs of soil nutrient conditions in the newly increased proteetive field （2004-2007） in Kuandian County showed that： the content of organic matter and alkaline hydrolysis nitrogen were in the middle level, the soil available phosphorus was low er, the soil area of pH value 〈5.5 occupied 23.5% that of the newly increase protective field. The fertilization recommendations were proposed based on the test results.
