In different soils environment to different model drip irrigation zone blockage difference, that is, need to select corresponding size according to specific soil regime
The drip irrigation zone of apopore prevents apopore clogging during trickle irrigation, meanwhile, prevent because aperture it is excessive caused by water source wave
Take, selects suitable drip irrigation zone to work as trickle irrigation operation first choice according to the specific percent information of silt in different soils environment.
Summary of the invention
In view of this, the present invention is directed to propose a kind of drip irrigation zone performance of anti-blockage detection method, to be closed according to soil information
Reason selects the Anti-blocked drip-irrigation band in corresponding aperture.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of drip irrigation zone performance of anti-blockage detection method, comprising the following steps:
(1), different sediment size groups are screened；
(2), different sediment size groups are mixed to form to the silt mixture of several different stages in different set ratio；
It (3), is each type test of 1.5g:1L proportional arrangement with muddy by each rank silt mixture quality and clear water volume ratio
Water；
(4), respectively drip irrigation zone sample corresponding with a type test muddy water, drip irrigation zone sample offer number for access
The apopore of a different pore size, water outlet hole number is identical with silt mixture rank number, empties air in the drip irrigation zone sample,
Drip irrigation zone sample apopore is blocked, each type test is filled with for the first time with muddy water to it and is corresponded in the sample of drip irrigation zone, and is protected
Demonstrate,proving hydraulic pressure in the sample of drip irrigation zone is setting pressure, opens and blocks, and detects each water outlet in the case where setting hydraulic condition of drip irrigation zone sample
The water flow for the first time in hole；
(5), stop into drip irrigation zone sample after water-filling 12 hours, drip irrigation zone sample apopore is blocked, it is secondary to the drop
It fills in band sample and is filled with its corresponding level test muddy water, and guarantee that hydraulic pressure is setting pressure in the sample of drip irrigation zone when the secondary water-filling
Power is opened and is blocked, and the secondary water flow of drip irrigation zone sample each apopore in the case where setting hydraulic condition is detected；
(6), compare each apopore for the first time, secondary water flow average value, deviation ratio is it in 5%---7% apopore
Corresponding level test is applicable in drip irrigation zone water outlet pore structure with muddy water.
Further, in step (1), silt is divided into three groups by particle size, one group of sediment grain size size and 80-100 mesh
Sieve screen apertures are corresponding, and second group of sediment grain size size and 100-120 mesh mesh are corresponding, third group sediment grain size size and and
120-160 mesh mesh are corresponding.
Further, in step (4) and step (5), apopore water yield detection time and the detection of secondary water yield for the first time
Time is respectively 4 hours.
Compared with the existing technology, a kind of drip irrigation zone performance of anti-blockage detection method of the present invention has the advantage that
A kind of drip irrigation zone performance of anti-blockage detection method of the present invention is manufactured according to different soils mud information and is tested
Then mud carries out blocking test to various aperture drip irrigation zones using the test mud, verifies the matched trickle irrigation of test mud
Band pore size, and then confirm that the aperture is that the mud is applicable in drip irrigation zone aperture, performance of anti-blockage when on the one hand improving trickle irrigation,
On the other hand water source has been saved.
