Problems solved by technology
The application of phosphate fertilizer has a significant effect on increasing the water seepage under the soil, but excessive phosphate fertilizer use may cause groundwater pollution and eutrophication of river water; water-retaining agent is a polymer polymer with super high water-absorbing and water-retaining capacity made of strong water-absorbing resin Because of its high water absorption, it promotes water infiltration, but the polymer cannot be recycled after implementation, causing long-term pollution to the soil; the promotion effect of biochar on water infiltration is limited by the application method and dosage. The method is more complicated

Embodiment
[0082] Step 1: Divide the fields in a chessboard style.
[0083] like figure 1 As shown, according to the condition of ground vegetation, the ground is divided into a checkerboard. When dividing, it is necessary to ensure that the root system of the vegetation is located in the middle of the square, and the division line is located between adjacent vegetation. After the division is completed, the side length of each checkerboard square field is L .
[0084] Step 2. Select the specifications of the inducement package and make the inducement package.
[0085] In the horizontal one-dimensional direction, the control range of each induction package can be approximated as a circle with the induction package as the center and a radius of R, and its control radius is equal to the side length of each square field.
[0086] R=0.5L (1)
[0087] In the formula, R is the control radius of the induction package; L is the side length of the checkerboard.
[0088] The height of the induc...

The invention discloses an inducing method for controlling the movement direction of water in soil and increasing the infiltration rate. The inducing method is specifically implemented according to the following steps: 1, firstly, carrying out chessboard-type division on the ground according to the condition of a ground vegetation; 2, selecting the size of an inducing bag to be arranged accordingto the size of a checkered of a chessboard; and 3, landfilling the inducing bag. The movement direction of water in soil can be controlled, and the infiltration rate can be increased.
Description
technical field [0001] The invention belongs to the technical field of agricultural irrigation methods, and relates to an induction method for controlling the movement direction of soil water and increasing the infiltration rate. Background technique [0002] Moisture movement is the physical process that water takes place in soil under the action of molecular force, capillary attraction and gravity. The water that reaches the ground can only be used by crops when it enters the soil and reaches the roots of the crops. When there is water on the soil surface, if the infiltration rate of water can be increased, the evaporation of surface water can be reduced, and efficient agricultural irrigation can also be realized. According to current research, the main factors affecting soil water movement are: soil texture, soil structure, soil moisture content in the early stage, water supply mode and intensity, water supply quality and soil temperature. Aiming at these main influencin...
