文章以新疆博州地区灰棕漠土、风沙土、黑钙土、栗钙土、灰钙土、棕钙土、盐土、亚高山草甸土、高山草甸土、森林土等土壤类型为研究对象,利用重铬酸钾法对各土壤类型有机质进行测定,通过结果分析出该地区土壤有机质的分布规律:有机质含量在0.36%-8.62%之间,表层土壤至深层土壤有机质含量上高下低趋势明显。
In this paper,all types of soil,including grey-brown desert soil,sandy soil,chernozems,castanozems,calcic grey soil,calcic brown soil,solonchaks,sub-high mountain meadow soil,high mountain meadow soil and sylvogenic soil in Boertala Mongolian Autonomous,are researched.Organic matter of soil is measured by potassium dichromate.The result indicates the range of the qualities of organic matter lies in 0.36%-8.62% and the upper is much than the deep.
