采集剖面样和耕层样分析中日大化科技扶贫项目两个中心试验基地的土壤基本性质，北景试验区为发育于砂页岩母质的红壤，土体风化淋溶强烈，属强酸性土壤，有机质及氮、磷、钾含量低，质地粘重，改良的根本措施是施用石灰，中和酸性，增施有机肥。七百弄试验区土壤是由石灰岩风化物发育而成的棕色石灰土，属中性至微碱性，有机质和氮、磷含量差异大，钾含量低，土壤结构松散，改良的主要措施是砌墙保土，防止土壤流失，合理施用有机肥和磷、钾肥。
Collecting profile and tillage samples The basic soil properties of two center test bases of Sino-Japan Dahua Poverty Alleviation Project were analyzed. The northern view of the test area is red soil developed from sandstone parent material. The soil is strongly weathered and leached, , Organic matter and nitrogen, phosphorus and potassium content is low, sticky texture, the fundamental improvement measures is the application of lime, acid and organic fertilizer. The test area of Qibaozong is a brown limestone soil developed from limestone weathering material. It is neutral to slightly alkaline with large difference in organic matter and nitrogen and phosphorus content, low potassium content and loose soil structure. The main measures for improvement are: Soil wall to prevent soil erosion, rational use of organic fertilizer and phosphorus, potash.
