Referring to fig. 1-4, a plant cultivation and identification pool for soil remediation, comprising an identification pool 1, wherein a waterproof cloth is arranged on the inner side of the identification pool 1, so as to reduce the influence of the pollution liquid 6 on the pool wall after long-term soaking, prolong the service life of the identification pool, and simultaneously enable the pollution liquid 6 flowing into the identification pool 1 to be remained in the soil in the identification pool 1 and be decomposed by plants, thereby avoiding the pollution liquid 6 put into the pool from seeping out of the identification pool 1 to cause inaccurate identification result, the bottom end of the identification pool 1 is fixedly connected with a stone layer 2, the top end of the stone layer 2 is fixedly connected with a sand layer 3, the top end of the sand layer 3 is fixedly connected with a soil layer 4, the two sides of the soil layer 4 are fixedly connected with pollution pools 5, the inner part of the pollution pool 5 is movably connected with an adjusting tank 6, the top end of the adjusting tank 6 is movably connected with a sealing cover 7, the bottom end, the position that pollution pond 5 and infiltration pipe 8 are connected is equipped with the opening, the height of 8 inner chambers of infiltration pipe is greater than the open-ended height that pollution pond 5 established, make the interior liquid level of infiltration pipe 8 can be higher than the open-ended height that the pollution pond established, can carry out the liquid seal to the opening that pollutes pond 5 through the pollution liquid that flows in the surge tank 6, make pollution pond 6 be encapsulated situation, thereby intraductal atmospheric pressure is less than the atmospheric pressure and oppresses the pollution liquid and no longer flows, make the volume of the pollution liquid of at every turn supplementing in appraising pond 1 fixed, thereby control the degree of soil pollution better.
Wherein, infiltration pipe 8 is latticed and distributes, make the soil more even and quick when polluting the liquid by infiltration pipe 8 infiltration in the soil layer of same height, simultaneously soil horizon 4 middle and two sets of infiltration pipe 8 on top can not block the root system growth of waiting to appraise the plant, make the deep root system of plant can be smooth prick into soil horizon 4 bottom growth through the net hole of infiltration pipe 8, infiltration pipe 8's top evenly is equipped with a plurality of openings, and opening position fixedly connected with filter cloth 9.
The side of the adjusting tank 6 is provided with three openings, the three openings are distributed at intervals of ninety degrees in the horizontal projection circumferential direction in sequence, the height intervals of the three openings are consistent with the height intervals of the three groups of water seepage pipes 8, and the adjusting tank 6 is rotated to enable different openings of the adjusting tank 6 to be over against the positions of the openings of the pollution pool 5 so as to change the groups of the water seepage pipes 8 connected with the pollution pool 5, thereby conveniently cultivating and identifying plants with strong pollution absorption capacity of root systems of different parts.
The inner wall of the pollution tank 5 is tightly attached to the adjusting tank 6, the adjusting tank 6 can freely rotate and move up and down along the axis of the adjusting tank 6, the opening of the pollution tank 5 under the initial position is just opposite to the closed opening of the adjusting tank 6, at the moment, the pollution liquid can be supplemented into the tank, the adjusting tank 6 is sealed through the sealing cover 7, the tank body is rotated by ninety degrees, the opening at the lowest end of the adjusting tank 6 is just opposite to the opening of the pollution tank 5, at the moment, the permeation tube 8 at the bottom end of the soil layer 4 is communicated with the adjusting tank 6, the pollution degree at the bottom end of the soil layer 4 is the highest, the plant with deep root system soil restoration can be conveniently cultivated and identified, the adjusting tank 6 is rotated by ninety degrees again, the opening of the permeation tube 8 at the bottom end is closed, the opening in the middle of the adjusting tank is just opposite to the opening of the pollution tank 5, at the moment, the plant, the opening of the contamination tank 5 can be closed by rotating again.
Meanwhile, the user can adjust the amount of the pollution liquid put in each time according to plants with different capacities, and the height of the top end of the opening of the adjusting tank 6 is changed by moving the adjusting tank 6 up and down, as shown in fig. 3 and 4, so that the controllability of the soil pollution degree of the same soil layer is realized, the direct death of low-capacity plants due to the fact that the pollution degree is fixed and uncontrollable is avoided, the dead seedling rate and the test failure rate are reduced, and the plant identification efficiency is greatly improved.
Wherein, can set up the height scale at 6 tops of regulation jar, set up the rotation angle scale on its upper surface, can confirm its height of adjusting and rotatory position through reading the scale value when user's rotation to accurately learn the degree of soil pollution and the contaminated soil layer of appraising 1 in this pond.
The using method of the invention has the following working principle:
when in use, the adjusting tank 6 is rotated to the initial position, so that the opening of the pollution tank 5 is just opposite to the closed opening of the adjusting tank 6, the sealing cover 7 is opened to supplement the polluted liquid in the adjusting tank 6, the sealing cover 7 is tightly covered after the supplement is finished to form a closed tank body, according to the characteristics of the cultivated plant root system, the adjusting tank 6 is rotated to enable the corresponding opening to be just opposite to the permeation tube 8 where the soil layer 4 with the plant dominant root system is located, so that the identification tank 1 with different polluted soil layers is obtained, then the height of the adjusting tank 6 is moved up and down to adjust the soil pollution degree of the soil layers, the polluted liquid flows into the permeation tube 8 through the openings of the adjusting tank 6 and the pollution tank 5, meanwhile, air is supplemented to the top end of the adjusting tank 6 through the filter cloth 9 with an opening at the top end of the permeation tube 8, when the liquid level in the permeation tube 8 is higher than the opening of the pollution tank 5, the opening is sealed by the polluted liquid, at the moment, under the influence of the weight of the liquid in the pipe, the pressure of the top of the tank is less than the atmospheric pressure, so that the polluted liquid does not continuously flow out, along with the gradual infiltration of the polluted liquid in the infiltration pipe 8 into the soil layer 4 and the absorption and decomposition of the polluted liquid by plants, the liquid level in the infiltration pipe 8 is reduced to be lower than the opening of the polluted pool 5, the liquid seal fails, so that the gas is filled into the top end of the adjusting tank 6 through the opening, the polluted liquid in the pipe flows out again until the opening is sealed, the restoration capability identification of the soil restoration plants with different depths of root systems is realized through the nonuniformity of the soil infiltration, the effect which cannot be realized by the uniform solution in the water culture is achieved, meanwhile, the real soil pollution environment is simulated, the difference between the identification result and the reality is reduced, the amount of the polluted liquid in the identification pool 1 at each time is changed by, and further reduces the death rate of plants and the failure rate of tests by controlling the pollution degree of soil.
