Specific implementation mode
To keep the above objects, features, and advantages of the embodiment of the present application more obvious and easy to understand, below in conjunction with the accompanying drawings and
Specific implementation mode is described in further detail the embodiment of the present application.
In the present embodiment, the control method of irrigation is applied to micro- profit irrigation system, and micro- profit irrigation is one kind with micro
The Novel irrigation technical method that water continuously irrigates crop, Core Feature device are the micro- waters for having micropore with tube wall
Micro- profit pipe is continuously irrigated as douche, douche can be porous for micro- profit pipe, porous ceramic pipe, porous metal tube, plastics
One kind in pipe.
By taking micro- profit pipe as an example, there is the sightless micropore of naked eyes, the aperture of the micropore is 10nm- on the tube wall of micro- profit pipe
The quantity of 900nm, micropore are at least 100,000 every square centimeter, it may also be said to, micro- profit pipe is a kind of polymer matrix, will be micro-
Profit pipe is placed into the soil, and when micro- profit pipe inner filling water after, micro- profit pipe is both the material interface of water and soil, at the same be again in pipe and
Power interface outside pipe, the direction of water flow and the size of flow depend on the height of pipe both sides energy.In to micro- profit pipe
When portion applies pressure, overpressure increases, and moisture manages outer soil by being flowed in pipe.Through experimental study, pressure and Wei Run can be obtained
Pipe release water relationship be：Y=AX+B, wherein Y is that every meter of micro- profit pipe discharges water (ml/m/h, milliliter/rice/small per hour
When), X is system working pressure (m, water-column), and A, B are respectively and the relevant coefficient of the soil texture.
For example, in clay loam, A=68.844, B=25.613 can be obtained,
Y=68.844X+25.613 R2=0.9953 (formula 1)；
As it can be seen that being in good linear relationship between the release water and pressure of micro- profit irrigation system, adjusted by pressure, it can be accurate
Really regulate and control the release water of micro- profit system, and precision can reach milliliter grade.
Wherein, R related coefficients are the amounts of linearly related degree between studying variable.R2 cries coefficient of determination or the goodness of fit,
When R2 closer to 1 when, indicate that relevant equation reference value is higher.
Such as：
As system pressure X=1.80m, the release water Y of micro- profit pipe is about 150ml/m/h, and the daily water that discharges is about
3600ml/m/d；
As system pressure X=1.85m, the release water Y of micro- profit pipe is about 153ml/m/h, and the daily water that discharges is about
3671ml/m/d。
The prior art is to control duty (discharging water) by adjusting pressure, and present applicant proposes a kind of inverse
To control method, i.e., with by adjusting flow come control pressure.
The hydro science behavior of micro- profit irrigation system had both been different from common opening line system (such as with steel pipe, plastic tube
For water-supply-pipe), also different from totally enclosed pipe-line system, micro- profit irrigation system itself is a special closed system, special
Different property is that system is both closed, can keep certain pressure, while can discharge water outward again, so that system is generated certain
Pressure drop, in this way, after being opened to the valve of system water supply, overpressure is not reduced to zero, but still possesses certain pressure.It protects
The size of pressure and the release water of micro- profit pipe are related, and the two is in a linear relationship, available according to formula (1)：
X=0.0146Y -0.374 (formula 2)；
