The experiment study on the soil infiltration characteristics of fenxi irrigated area in Shanxi province

Northern China is short of water, especially in Shanxi province is dry. The water used for irrigation is a main part of the all water we used. Therefore, studying of soil infiltration characteristics and determining the appropriate irrigation technology can save a large part of the water, which can extent alleviate much water pressure. Based on agricultural research project of Shanxi Province (No.20100311124), changes in soil water infiltration process and the impact of soil water infiltration factors are studied systematic in this article, and water infiltration characteristics of soil factors are analyzed by mathematical statistics. The test included Outdoor experiments and trenching excavating soil infiltration test and the grain size indoor experiments and determination of organic matter used for analyzing soil of Fenxi Irrigation shows that factors which influence field soil water influence field soil water infiltration characteristics have soil structure, soil moisture, soil texture, soil organism quality, topsoil crusting and plate, agriculture husbandry measure and so on. The soil water infiltration capacities offer increase while soil moisture going down, or it did in high physical clay content soil.
