土壤有机质(soil organic matter,SOM)是一项评判土壤质量状况的重要因子,其含量的高低对农业生产活动具有重要作用.本文采集了江南地区三种不同植被下的土壤样品,在实验室使用重铬酸钾外加热容量法测定土壤有机质含量.结果发现,原始树林土壤有机质含量为11.6 g/kg,茶田为19.2 g/kg,竹林为36.8 g/kg.
Determination of Soil Organic Matter Content under Different Vegetation
Soil organic matter is an important index to measure soil quality,and its content plays an important role in agricultural production.In this paper,soil organic matter content was determined by potassium dichromate external heating capacity method using soil samples of three different vegetation types in Jiangnan area.The results showed that the soil organic matter content was 11.6 g/kg in the original forest,19.2 g/kg in the tea field and 36.8 g/kg in the bamboo forest.
