| 摘 要： | 采用室内土柱淋溶模拟试验方法，以棕壤为供试土壤，研究了在一次中等程度的降雨条件下钙肥在土壤垂直方向上的淋溶迁移特征。结果表明：随钙肥施用量增加，土壤中有效态钙含量增加2.2％～22.4％，钙的淋溶率高达48.6％～80.4％，差异均达显著性水平；适当的钙、磷组合，即当钙磷的施用配比为1：1时，能够使钙淋溶率降低31.8％，土壤有效态钙的含量总和增加6.0％，能在提高土壤有效钙含量的同时，使钙肥的淋溶率降低。

| Abstract: | Soil column is used to study the characteristics of calcium movement in uprightness direction in Brown-soil which is in a middling rainfall condition. The result shows that with the increase of calcium which input to the soil,the availability calcium is markedness increased by 2.2%~22.4%, and theloss of the calcium is markedness heighten to 48.6%~80.4%; suitable combination of calcium and phosphorous can make the eluviate rate reduce by 31.8%,the summation of availability calcium increased by 6.0%.When the content of calcium and phosphorous is 11, it can enhance the availability calcium in soil effectually and reduce eluviate rate of calcium. |
