Abstract

The invention discloses a method and system for controlling and evaluating preferential flow degrees of soil. The method comprises a field dyeing tracing test step: collecting a dyeing profile image after the dyeing tracing test is finished; a picture processing and picture element extraction step: processing the dyeing profile image into a binary information matrix consisting of black and white,and converting the picture into a bitmap format; a parameter calculation and preferential flow degree evaluation step: selecting a representative preferential flow maximum infiltration depth, a representative soil profile dyeing area ration, a representative matrix flow area depth and a representative preferential flow fraction; and a preferential flow degree response analysis step: analyzing a linear relationship between irrigation volume levels and preferential flow indexes, and carrying out check analysis on the indexes under same irrigation volumes and different charcoal treatments.

Description

technical field [0001] The present disclosure relates to the technical field of soil cultivation, in particular to a method and system for resistance control and evaluation of soil preferential flow degree. Background technique [0002] The so-called preferential flow refers to the phenomenon that water and solute quickly migrate to the deep soil and groundwater along the preferential path in the soil (soil shrinkage cracks, root pores produced by root growth, and animal activity channels, etc.). The prerequisite for the occurrence of preferential flow is that there is a channel for its migration in the soil, that is, the existence of the preferential path, and secondly, it needs to be driven by hydrodynamic conditions. [0003] Studies have shown that the phenomenon of preferential flow in soil is not a special case. About 70%-85% of the water movement in soil is related to preferential flow, which is recognized as a potentially important infiltration mechanism in soil. Th...
