The Experimental Investigation Of Saturated Hydraulic Conductivity On The Condition Of Water Storage Pit Irrigation

Water storage pit irrigation is a new kind of irrigation method presented for solving drought and soil erosion in the north of China, and has extensive application foreground. The research of the method is still in indoor study stage. Its water saving mechanism and some technical parameter still need to be confirmed. Therefore, the further researching for water storage pit irrigation has great theoretical and practical significance.For meeting the further researching of water storage pit irrigation, the main investigation content are as follows:1 , The experimental investigation of saturated hydraulic conductivityFirstly, making infiltration water head as control factor, experiments are carried out about saturated hydraulic conductivity under different infiltration water head. The conclusion is that saturated hydraulic conductivity can be affected by infiltration water head in some degree. Then, making bulk density of soil as control factor, experiments are carried out about saturated...
