- 摘要:
- 中国东北地区土壤普遍受到的季节性冻融作用会影响土壤中速效磷和水分的垂直分配。通过室内模拟冻融环境，分析了冻融循环条件下黑土速效磷和土壤水分的垂直变化。结果表明：多次冻融循环作用使土壤速效磷随着土壤水分由下层向表层迁移，经30次冻融循环作用后土壤最大含水率和土壤最大速效磷含量均出现在3 cm层；土壤初始含水率越高，冻融作用后向土壤表层迁移的速效磷含量越大，但随着冻融循环次数增加，土壤各层速效磷含量都有所下降，1次冻融作用后，土壤速效磷的最高含量为50.63 mg/kg，30次后最高含量为43.81 mg/kg，减少了13.5%；利用多元回归分析分别得出了冻融循环后土壤含水率和速效磷与初始含水率、冻融循环次数和土层深度的关系函数，相关系数分别为0.892，0.578。上述研究成果为季节性冻融区非点源污染及土壤盐碱化防治奠定理论基础。
- Abstract:
- Soil is generally influenced by seasonal freeze-thaw cycle in northeast of China, which makes available phosphorus and moisture move and redistribute. The indoor simulated freezing and thawing environments were explored to investigate the available phosphorus and moisture vertical movement under freezing and thawing condition. The results showed that the soil available phosphorus, below the frozen layer, moved up with soil moisture under multiple freeze-thaw cycles; and after 30 times of successive freeze-thaw cycles maximum moisture content moved up and appeared below 3 cm of layer; the higher initial soil moisture, migrating to the upper layer of soil available phosphorus was higher after freeze-thaw cycles. But with increase of number of freeze-thaw cycles the soil available phosphorus content decreased. After one freeze-thaw cycles, the highest content of soil available phosphorus was 50.63 mg/kg. After 30 times of successive freeze-thaw cycles, the maximum content of soil available phosphorus was 43.81 mg/kg, reduced by 13.5%. The authors established the relational function between soil moisture content and available phosphorus with the initial moisture content, freeze-thaw cycles and soil depth, respectively, by the method of multiple regression analysis, and the coefficients of correlation respectively were 0.892 and 0.578. This research results will lay a foundation for preventing the non-point source pollution and soil salinization.
