The present invention is described in detail with reference to the accompanying drawings and detailed description.
The present invention provides a kind of soil moisture control direction of motion and improve the abductive approach of infiltration rate, specifically according to
Following steps are implemented：
Step 1, ground is carried out by checkerboard type division according to ground vegetation state first；
Step 2, it is selected to arrange induction bag specification according to the size of checker；
Step 3, induction bag landfill.
Step 1 is specially：According to ground vegetation growth status, ground is subjected to checkerboard type division, vegetation root system during division
In checker, dividing line is between adjacent vegetation.
Induction bag in step 2 is cylinder, is induced between the cylindrical radius r of bag and induction bag control range radius R

Carry out digging induction bag placement hole in each checker vertex in step 3, it is trapezoidal, hole to cheat in vertical section
Low a diameter of 1.2-1.4 times of induction bag diameter, crater wall gradient is 75 °.
Induction bag production method be：
Step a, according to the size of required induction bag, chooses the induction bag material for making induction bag, is wrapped with the induction
Bag material manufactures size and is：Width edge length is d=π r, and long edge lengths c, wherein c ＞ h, obtain induction bag, then by the one of broadside
End sealing, another end opening；
Step b, water-absorbing material is filled into induction bag according to certain density, then unencapsulated one end carries out
Inflection seals, the length m=c-h of inflection, forms complete induction bag.
When making induction bag, sealed at sealing using waterproof material.
The principle of the present invention is：
According to soil water movement equation, induced and wrapped by manual manufacture, the artificial energy for changing soil moisture, carries
For additional soil water suction, change wet gradient, induce soil water movement, improve moisture infiltration rate and control moisture movement
Direction.
In energy point of view, soil water movement submits to thermodynamics second theorem, always from the high ground oriented energy of energy
Low place is mobile.According to classical physics, energy that material has can be divided into kinetic energy and potential energy, and soil water movement speed
It is relatively slow, the generally kinetic energy without considering soil moisture, therefore soil moisture potential typically refers to its potential energy.Soil moisture is had
Potential energy be divided into gravitational potential, matric potential, pressure potential and solute potential.Total soil water potential is point that all motive powers produce in soil
The summation of gesture, i.e.,
In formula,For total soil water potential；For matric potential；Solute potential；Pressure potential；Gravitational potential；Temperature potential.
In saturated soil, pressure potential and gravitational potential are only existed, i.e.,
In unsaturated soil,WithInfluence to soil water movement is all negligible, then formula (1) is reduced to
Induction bag provided by the present invention, there is provided additional soil water suction, produces additional potential, withRepresent, be
Negative value.Then in unsaturated soil, induce in bag controlled range, formula (3) is changed into
Soil water potential is calculated by formula (3) in unsaturated soil without induction bag, has in the soil that induction wraps total soil water potential by formula
(4) calculate, according to quantitative relation, can be apparent fromIn formula,For without total soil water potential in induction bag unsaturated soil；
To there is total soil water potential in induction bag unsaturated soil.
In moisture infitration process, with Water Flux in the case of Darcy's law describing one dimension, the difference of earth pillar both ends potential energy
In formula,For the difference without induction bag earth pillar both ends potential energy；To there is the difference of induction bag earth pillar both ends potential energy；For
Total soil water potential in saturated soil, is calculated by formula (2).
According to quantitative relation, hence it is evident that draw
Darcy's law is described as soil water movement under one-dimensional case
In formula, q is soil moisture flux；For the difference of earth pillar both ends potential energy；L is earth pillar length；ksLed for soil saturation
Water rate.
Formula (8) is brought into according to formula (5), (6) to can be calculated, no induction bag soil water movement flux q, and have induction bag soil
Earth moisture movement flux q ', according to quantitative relation, hence it is evident that can obtain
Q ＜ q ' (9)
So, abductive approach provided by the present invention, can be effectively increased soil moisture flux.
To water infiltration process, Green-Ampt is by being distributed soil water movement feature and soil moisture content
Analysis and generalization, proposition ground moistening sharp side level, wetting zone there are immobilize a suction and wetting zone more than
Soil be in saturation state it is assumed that Green-Ampt is proposed on the basis of Darcy's law infiltrates formula
I=(θs-θi)zf (11)
In formula, zfFor the wetting front depth generally changed；hfFor suction at wetting front；H is surface area water depth；
θsFor saturated soil water content；θrTo be detained soil moisture content.
In technical method provided by the invention, the induction bag of manual manufacture provides artificially additional soil water suction, uses hadd
Represent, according to formula (10), then soil infiltration rate is expressed as after implementing induction bag
The soil infiltration time is expressed as into after according to formula (12), implementing induction bag
It can substantially obtain, after implementing the abductive approach, infiltration rate increase, infiltrates time reduction.
Wrapped in the vertex landfill induction of checker, then centered on crop root, in the range of an approximating square,
It is subject to four apex angle induction bags while influences, moisture infiltration rate is most fast, and moisture highest.The approximating square length of side is about
For
L=0.6L (18)
For each checker field, after implementing induction bag, its vertex moisture is less, and center section moisture contains
Amount is higher, and moisture is concentrated on around crop root, realizes water-saving irrigation.
The induction bag of manual manufacture of the present invention, artificially changes hydraulic gradient, oozes direction under controllable moisture.It is each independent
Induction bag control range it is certain, and closer to induction bag soil water content it is lower, further away from induction bag soil moisture
Content is higher.

75°.The destruction ground original appearance as few as possible while convenient working.
As shown in Figure 5, as shown in fig. 6, bag inflection will be induced to seal, one end is downward, is vertically put into the hole dug.Fill out
Bury soil density to be consistent with surrounding nature soil, and induce bag top to be less than ground surface 2-10cm, top is covered with soil
Lid, mulching soil density are consistent with surrounding nature soil.
As shown in fig. 7, induction bag influences situation.Induction bag is filled in each checker field vertex.With crop
Centered on root system, in the range of an approximating square, it is subject to four apex angle induction bags while influences, moisture infiltration rate is most fast,
And moisture highest.The approximating square length of side is about l=0.6L=0.6m.
For each square field, after implementing induction bag, its vertex moisture is less, center section moisture
It is higher, moisture is concentrated on around crop root, realizes water-saving irrigation.
