巴东长江两岸旱地土壤质量评价

On the sides of Yangtze River dry soil quality assessment in Badong region

采集了100个样地的土壤,选取土壤pH值、有机质、碱解氮、有效磷、速效钾等评价因子,再将各属性值分级标准化,采用修正的内梅罗公式对采样区域的土壤质量进行评价,结果表明,长江以北地区的土壤质量属一般水平,主要限制因子为土壤的速效磷;长江以南地区的土壤质量属肥沃水平。

We collected 100 soil samples and selected the soil pH, organic matter, nitrogen, phosphorus, potassium and so on evaluation factors, then adopted the property value grading standards, using the modified Nemero formula to evaluate soil quality. The results showed that the area north of the Yangtze River is the general level of soil quality, the main limiting factor was available phosphorus; the Yangtze River south of the region is fertile soil quality standards.
