Experimental Research On The Soil Moisture Movement Of The Water Storage Pit On The Condition Of Evaporation

In northern China, drought and soil erosion are very severe. Water storage pit irrigation is a kind of new irrigation method that solves the two problems in hilly region. This method has the characteristic of saving water, molding moisture, drought defying, increasing production and decreasing soil erosion. In the paper, the objectives are to ascertain sound the technical parameter and evaluate the irrigation effect of the water storage pit method by researching the soil moisture movement of the water storage pit method in order to provide the theoretical base for researching on storage pit irrigation from the indoors to the field.In this paper, the main results are as follows:1. The experimental study of the soil moisture movement on the evaporation condition of vertical experiment on one dimensionBy the experimental study of the soil moisture movement on the evaporation condition of vertical experiment on one dimension the main conclusions are as follows:(1) The effect of the bulk density on the soil accumulative evaporation capacityThe soil accumulative evaporation capacity dwindled away with the...
