| 摘 要： | 笔者探索了石灰性土壤中Ca—P的分级测定方法,使Ca—P总量提取率高于张守敬法的41.3％、苏联的53.5％。相关分析证明,其有效性亦以笔者的方法(r=0.680)为优,从而使该法成为判断石灰性土壤储磷能力的可靠手段,也为土壤肥力的研究和土壤基层分类提出了依据。

| Abstract: | The total extracting amount of Ca-P from calcareous soils by using the fractional analysis method is 41.3% higher than that of the soviet method. The correlation analysis also shows the author's method (r=0.680) is better than the other two methods. This method also can be used as a criterion to determine the potential activity for supplying phosphorous in calcareous soils and to provide scientific basis for the researching of soil fertility and classification of soils. |
