经使用土壤箱，采用两种水分运动和两种梯形垅，研究滴灌水的有效供水率表明．与时间、流速有关的水平运动和垂直运动之间存在一种明确关系。这种关系在双对数坐标上呈直线变化。研究还发现，水分运动在自然对数坐标系中呈半椭圆关系。因此，可以利用这种研究来设计垅上生... The use of soil boxes, using two kinds of water movement and two trapezoidal 垅, the study shows that the effective water supply drip irrigation showed. There is a clear relationship between horizontal and vertical movements related to time and velocity. This relationship varies linearly in double logarithmic coordinates. The study also found that the water movement in the natural logarithmic coordinate system was semi-elliptical relationship. Therefore, we can use this research to design students.
