| 摘 要： | 本文比较了研究土壤氮素释放规律的几种方法,首次提出在培养基质中添加阴阳离子交换树脂可以替代 Stanford 等提出的好气培养、间隙淋洗法,从而使该方法得到简化而更接近于实际土壤条件,在大面积测土施肥建议中本试验所推荐的方法有其较大的推广价值。本报告还提出了采用作者所建议的方法时应注意的几个问题,较完善地论述了好气培养测定土壤氮素释放规律的方法。

| Abstract: | Different methods of studying soil nitrogen mineralization were compared.The con-cept of soil nitrogen mineralization potential was proposed by Stanford who adopted theincubation method with intermitent leaching to remove the reaction products.In our in-vestigation we used the incubation method by adding ion exchange resins to the testedsoils in order to remove the reaction products.This method is much more convenient andaccurate than Stanford's.It is also closer to the existing conditions in the soil and can bewidely used to check the soil tests in nitrogen fertilizer recommendations.Some noteswere also presented for using this method. |
