【摘要】 为了扩大农林资源,加快盐渍土利用改良和农林生产步伐,探明盐渍土壤中的养分及盐基组成状况十分必要。对南皮土壤进行采样分析,结果表明:该区土壤有机质及氮、磷、钾含量较少,盐分含量较高,土壤肥力水平偏低,不利于植物的正常生长;土壤养分、总盐分与各种盐基离子在土体中的分布具有明显的表层积聚特点。更多还原

【Abstract】 In order to widen agricultural and forestry resources and to accelerate salinized soil improvement and agriculture and forestry production, it is necessary to ascertain the nutrients and salt group composition condition of this kind of soil. Analysis of soil samples from Nanpi county showed that the contents of organic matters and nitrogen, phosphorus, potassium were rather low, but with high salt content. So the soil productivity is relatively low which is not suitable for plant to grow. The distributions of soil nutrients, total salts and various base ions in soil showed obvious characteristies of surface layer accumulation.更多还原
