【摘要】 [目的]测定青海不同地区土壤中有机质的含量。[方法]用外加热法和重铬酸钾容量法对青海10个不同地区土壤和泥炭中的有机质含量进行了测定。[结果]大通、门源、共和、天峻的土壤有机质含量在36.79～58.64 g/kg,玉树、祁连、刚察、兴海、湟源、化隆的土壤有机质含量都较高,在155.90～287.00 g/kg。其中,祁连的土壤有机质含量最高,为287.00 g/kg。[结论]测定方法可靠,数据准确,为青海泥炭资源的普查和开发利用提供了科学依据。更多还原

【Abstract】 [Objective] The research aimed to determine the organic matter content in soil from different areas in Qinghai.[Method] The organic matter content in soil and turf from 10 areas in Qinghai Province was determined by external heating method and potassium dichromate volumetric method.[Result] The results showed that the organic matter content in soil from Datong,Menyuan,Gonghe and Tianjun was 36.79~58.64 g/kg,and that from Yushu,Qilian,Gangcha,Xinghai,Huangyuan and Hualong was 155.90~287.00 g/kg.Thereinto,the organic matter content in soil from Qilian was the highest,was 287.00 g/kg.[Conclusion] The determination method was credibility and the data was nicety,can provide the scientific basis for general investigation and exploiting turf resources in Qinghai Province.更多还原
