| 摘 要： | 以较系统的观测资料,对土壤环境中的缓效态、速效态、水溶态钾素含量的动态变化进行探索.结果表明,缓效态钾的季节性动态变化制约着速效态、水溶态钾的季节性动态变化,但是后两者变化幅度较缓效态钾的大;这种动态变化同时受土壤类型和深度的影响.

| Abstract: | Based on fairly systematic observational data, the
authors probed into dynamic variations of slow-released, rapid available and water soluble
potash constituents in the rock-soil environment. The results show that the seasonal dynamic
variation of slow-release potash constituents will condition that of the rapid available and water
soluble potash constituents, with the variation range of the last two sorts of constituents larger
than that of the first sort.Such dynamic variations are also influenced by soil types and soil
depths. |
