采用均匀布点的方法研究重庆市丰都县耕层土壤有机质状况,结果表明土壤类型对土壤有机质影响较大;土壤有机质含量变幅较大(0.30～69.72g/kg),大多数(69.65%)在10～20g/kg;近年土壤有机质含量明显增加,但总体上仍处于较低水平。提出推广测土配方施肥技术,加大有机肥的使用量是提高丰都县土壤有机质含量的重要措施。
The results showed that the soil types had a significant effect on soil organic matter. The content of soil organic matter varied greatly (0.30-69.72g / kg), and the majority (69.65%) of soil organic matter in the topsoil of Fengdu County, In 10 ~ 20g / kg; In recent years, soil organic matter content increased significantly, but in general it is still at a low level. Put forward to promote soil testing and fertilizer technology, increase the use of organic fertilizer is an important measure to improve soil organic matter content in Fengdu County.
