Matter, the aperture that filter hole thereon is diameter 2mm.
The application method of solute exchange simulator, sequentially includes the following steps: between a kind of soil macropore domain and matrix domain
(1) when testing, water pump is opened, keeps solute in water tank (aqueous solution) with a constant stream by adjusting self-action balanced valve
Amount discharge, solute uniformly passes through infiltration disk and infiltrates under the effect of gravity, simulated rainfall process, and is supervised in real time by flowmeter
Survey actual flow size, record solute in the soil infiltrate the time；Solute passes through circular cover and current divider respectively, open into
Water valve will flow through solute in circular cover and current divider and be collected in the first graduated cylinder, the second graduated cylinder respectively, records final total stream
Amount；(2) the tracer ion concentration that the change of moisture content of TDR probe records and resistivity feeler lever record is real-time transmitted to computer
On, and analyze and research, obtain solute exchange rule between different moments matrix domain and macrovoid domain and infiltrate feature；(3) it tries
After testing, self-action balanced valve is closed, opens outlet valve, solute is finally collected in waste water container.
Since macrovoid domain is consistent with the depth in matrix domain, so only needing to consider transparent cylinder cross-section macrovoid
The ratio between area and substrate area, according to plant bulk it is found that ideally, finally flowing into the first graduated cylinder and flowing into the second graduated cylinder
The ratio between solute flow should are as follows:
π × (24/2)2 : π × (2/2)2×4 = 36:1
And considering macroporous presence, solute will be infiltrated unevenly, and there are solutes to exchange between matrix and macrovoid, so
It cannot be simply by area ratio reduced discharge ratio under perfect condition.Only because the coarse sand and rubble filled inside macrovoid are more
Hole medium, compared to clay closely knit in matrix, hydraulic conductivity is higher inside macrovoid domain, and resistance is smaller, therefore, moisture and solute
Soil matrix can be bypassed in infiltration process, preferentially flow through the stronger macrovoid domain of water transmitting ability, two graduated cylinders actually collected
Flow-rate ratio can be more much smaller than ideally calculated value.
So we assume that practical first graduated cylinder flow is a, the second graduated cylinder flow is b, and exchange capacity x can obtain conversion
Formula:
(a+x): (b-x)=36:1
It quantitatively can obtain exchange capacity x of the solute between two domains, to guarantee data reasonability, repeat test procedure,
3 test average values are taken, indirect analysis solute exchanges rule between two domains.
