An understanding of soil moisture content variability is fundamental in hydrological studies of peat soils, whose preservation depend on water‐related processes. Dehydration of fens and adapting them for agricultural production have contributed to the degradation of peat soils. The goal of this study was to determine how the critical soil moisture content (CSMC) and soil water repellency (SWR) affect soil moisture patterns in a degraded peat‐muck soil profile. SWR was measured under laboratory conditions using the water drop penetration time test, and then the CSMC was assessed. An investigation of moisture patterns was based on soil moisture data collected over short distances in a grass‐covered peat‐muck soil profile on seven dates. Observed differences in moisture patterns demonstrate that the CSMC can be used for the prediction of preferential flow occurrences in peat‐muck soils. Lower values of the CSMC and lower levels of SWR persistence in muck layers than in peat layers indicate that degradation of peat soils improves their wettability. The relatively low values of CSMC and the low shrinkage potential in the muck layer suggest that preferential water flow in the degraded organic soils can occur when heavy rains are preceded by long periods of summer drought.

选取5种工矿废渣进行室内模拟试验,研究不同种类工矿废渣作为硅肥施用对土壤钙、镁、铁、铝释放的影响及其与硅素释放间的关系。结果表明:y=kxm方程可以很好地描述土壤钙、镁、铁、铝释放的动力学过程,Ca释放动力学方程yCa=kCaxmCa中的参数kCa与Si释放动力学方程ySi=kSixmSi中的参数kSi表现为极显著的直线正相关关系;钙镁累积释放量之和及铁铝累积释放量之和分别与硅素累积释放量呈极显著的幂函数正相关和直线正相关关系。施用废渣可降低土壤中铁、铝的活性,甚至可增加钙、镁的含量,从而在提高土壤供硅能力的同时起到改良土壤的作用,且高炉渣A和高炉渣F的施用效果要优于高炉渣B、粉煤灰H和金刚石矿渣J,是加工硅肥的适宜原材料。 相似文献
