施用不同有机物料对坡耕地水分入渗特征的影响
Effects of Different Organic Materials on Water Infiltration Characteristics of Sloping Farmland
摘要
Abstract
Soil and water loss is the most typical and long-term continuous impact on ecological environment.Due to the seasonal distribution of rainfall and human factors,soil and water loss will occur in sloping farmland.In this paper,the effects of different organic materials on infiltration of sloping land were analyzed from the perspective of time and space,and the control path of organic materials on infiltration capacity of sloping land was investigated by using structural equation model.The results show that the application of organic materials could improve the soil water infiltration capacity of sloping farmland.Compared with CK treatment,the saturated water conductivity and saturated water content of soil treated with chicken manure were significantly increased by 134.79%and 6.50%respectively.As the crop grows longer,soil water in-filtration increased at day 150 compared with day 30,and there were some differences in the effect of slope location and soil depth on soil water infiltration after application of organic materials.Judging from the fitting effect of infiltration,Hor-ton model is the best fit for this infiltration process.From the structural equation model,soil water characteristics,soil pore characteristics and soil bulk density played key role in the influence of soil water infiltration,and different organic materi-als have different control paths for soil infiltration due to their different properties.Overall,chicken manure treatment has the best effect on improving soil infiltration performance and reducing soil bulk density,while bacterial residue treatment has the best effect on improving soil pore characteristics and soil water characteristics.关键词
