通过肥液间歇和连续入渗实验,分析了肥液间歇入渗土壤湿润特性。结果表明,肥液间歇入渗湿润锋运移速度较连续入渗慢,并随周期数的增加而减小;分析了肥液间歇入渗湿润锋运移的分段模型,提出了由连续入渗湿润锋运移参数计算间歇入渗湿润锋运移距离的简化模型,实例计算表明该方法简单有效;对比了肥液间歇入渗和连续入渗土壤含水量的分布,肥液间歇入渗土壤含水量分布较连续入渗均匀,相同深度土层中入渗水量占总入渗量的比例较大。

通过向土壤中施加不同含量的羟丙基甲基纤维素(简称HPMC),研究了HPMC对土壤水分入渗特性及土壤水稳性团聚体的影响。结果表明:(1)土壤中施加一定量的HPMC可以显著降低土壤入渗能力,在施加量为0~1.0 g/kg范围内,累积入渗量、湿润锋运移距离和入渗率均随施加HPMC含量的增加而显著减小;利用Philip方程和Kostiakov公式对实测数据进行拟合发现,两者均能较好模拟施加HPMC后土壤的入渗过程,随HPMC施加量的增加,吸渗率S、稳渗率A和经验系数K明显减小,经验指数β逐渐增大。(2 ...
