| 摘 要： | 比较研究了利用传统的油浴法和150℃电热干燥箱恒温加热20、30、40min后，测定5种不同土壤腐殖质的含碳量。结果表明：150℃电热干燥箱恒温加热30、40min与油浴法之间不存在显著差异，但加热30min的测定方法与油浴法间的相关性更显著(Y=1.0082X+0.0003,r=0.9992**)。150℃干燥箱恒温加热法具有操作简便、重现性好、无实验室二次污染等优点。

| Abstract: | The traditional oil-melt method and drying over digestion for 20minutes ,30 minutes and 40 minutes under 150 ℃ were employed to measure the organic carbon content in soil humus extracts. The results indicated that there was not significant difference between the drying over digestion for both 30 minutes and 40 minutes at 150 ℃ and the traditional oil-melt method. It was found that the correlation between traditional oil-melt method and digestion for 30 minutes at 150 ℃ in drying oven was more significant (Y=1.008 2 X +0.000 3,r=0.9992**). 150 ℃ drying oven digestion method has the advantages of easier operation, better reproducibility, no laboratory pollution, etc. |
