| 摘 要： | 对我省互助县丹麻西灌区农田耕层土壤养分丰缺状况进行调查。结果表明:试验区土壤呈微碱性,有机质含量较低,碱解氮含量处于中等水平,速效磷含量较丰富,速效钾含量丰富且变异性较大。应采取:增施有机肥料、稳定氮肥、控制磷肥、针对性补充钾肥等措施改良土壤。

| Abstract: | The tillaged Soil nutrient status were investigated in westhern irrigation region of Danma Huzhu.The results showed that the soil are alkaline the organic content are lower,the amounts of alkli hydrolyzable nitrogen are at the midium level,the soil is rich in avai lable phosphorus and potassium,but the latter showed a high variation,the measure of soil amelioration should take adding organic fetilizer stabilization nitrogen controlling plosphate fertilizer and complementarity potassium fertilizer. |
