摘　　要：对土壤养分状况系统研究法(ASI法)与重铬酸钾外加热法测定土壤有机质的结果进行了相关性比较。结果表明,中性和碱性土壤ASI法与重铬酸钾外加热法的测定值呈显著正相关,且两种方法的测试值之间存在一定的比例系数。The correlation between ASI method and potassium dichromate external heating method for soil organic matter determination is compared.The results showed that under neutral and alkaline soil conditions,the ASI method and the potassium dichromate exter⁃nal heating method were significantly positive correlation,and there was a certain proportion coefficient between the test values of the two methods.
