Abstract
The utility model relates to a soil leaching simulating device, in particular to a device for simulating the leaching of agricultural medicine in soil in a laboratory. The soil leaching simulating device comprises a leaching simulating column and a soil separating plate, wherein the leaching simulating column comprises a semi-cylinder body, a fixed bracket, a fixed ring, a water-flow diversion plate, a soil baffle plate, a semicircular projection and an end cover; and the soil separating plate is a plastic separating plate with the size being consistent with that of the cross section of the semi-cylinder body. The soil leaching simulating device has small leaching simulation error, is simple to operate, is convenient and accurate to sample, and is particularly suitable for determining the leaching property of weedicide through a biological testing method.
Description
(1) technical field
The utility model relates to soil environment research experiment device, specifically carries out the device of agricultural chemicals leaching simulation in soil in the laboratory, especially is fit to measure the leaching of herbicide in soil with the method for biologicall test.
(2) background technology
Leaching has been proved to be the phreatic main cause of pollution by pesticides.The migratory behaviour of research agricultural chemicals in different soils, can be prediction and estimating agricultural chemicals provides scientific basis to the phreatic extent of injury, more necessary for the exploitation of novel pesticide.The leaching of agricultural chemicals in soil comprises leaching test of actual farmland and laboratory examination.The field test research process is too tediously long, and workload is big, need to drop into great amount of manpower and material resources, and test condition is wayward, and sampling is convenient inadequately, accurate, can't obtain consistent result.Laboratory examination has simple characteristics, and because the cycle is short, can ignore agricultural chemicals in degradation in soil and volatilization.Therefore, people wish by can simulate the leaching device of field soil level in indoor foundation, to overcome the defective of field experiment, but this just has higher requirement to soil eluviation simulator, and existing leaching device is when leaching, wayward current, soil disturbance easily takes place, simulation error is big, and sampling is convenient inadequately, causes test findings inaccurate.
(3) summary of the invention
The purpose of this utility model is to provide a kind of leaching simulation error little, simple to operate, and sampling is convenient, accurate, is particularly useful for measuring with the method for biologicall test the soil eluviation simulator of the leaching of herbicide.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises: leaching simulation post and soil demarcation strip two parts, and wherein leaching simulation post comprises: semicylinder, fixed mount, set collar, current dispersion plate, soil baffle plate, semi-cylindrical hill, end cap; The soil demarcation strip is the plastic septum consistent with the semicylinder cross sectional dimensions.
The utility model can also comprise some features like this:
1, on the leaching simulation column outer wall capacity index line is arranged, other capacity sign value, the accurately filling soil of indicating of capacity index line.
2, end cover surface is provided with many micropores, is used for drenching the fluid outflow every living soil and make, and can join a funnel and gatherer voluntarily according to the experiment needs, collects and drenches fluid.
Advantage of the present utility model and beneficial effect are:
1. simple in structure, easy to operate.Each assembly of leaching simulation post is installed simple, has scale on the leaching simulation post, can accurately fill semicylinder and be convenient to separate as required soil.
2. leaching is effective, and the leaching simulation error is little.Leaching simulation post upper end is provided with current and disperses baffle plate, can make water be distributed to soil surface equably.
3. sampling is convenient, accurate.After the leaching experiment finishes, set collar is opened, separated two semicylinders, fixed mount keeps flat, and as required soil intactly is separated into several parts with the soil demarcation strip, is convenient to accurate sampling and measuring pesticide concentration.
4. be particularly suited for measuring the leaching of herbicide with the method for biologicall test.Sensitive crop is planted in the soil of separation and can measures herbicide content intuitively, exactly.
5. it is recyclable to drench fluid.The end cover surface of leaching simulation post has many micropores, is used for drenching the fluid outflow every living soil and make, and can join a funnel and gatherer voluntarily according to the experiment needs, collects and drenches fluid, is used for the instrumental analysis detection and drenches the fluid pesticide concentration.
(4) description of drawings
Fig. 1 is the structural representation of leaching simulation post in the utility model, and Fig. 2 is the synoptic diagram of soil demarcation strip 8.
(5) embodiment
For example the utility model is done description in more detail below in conjunction with accompanying drawing:
The composition of soil eluviation simulator comprises leaching simulation post and soil demarcation strip two parts, and wherein leaching simulation post comprises: 1 semicylinder, 2 fixed mounts, 3 set collars, 4 current dispersion plates, 5 soil baffle plates, 6 semi-cylindrical hills, 7 end caps.
Especially it is to be noted, this method of installing available biologicall test is measured the content of herbicide, and method is to plant sensitive plant in every section soil, determines the content of agricultural chemicals according to the difference of growing of sensitive plant, this method is quick, accurate, easy, cheap, and effect is directly perceived.
Claims (1)
1. a soil eluviation simulator comprises leaching simulation post and soil demarcation strip two parts, and wherein leaching simulation post comprises: semicylinder, fixed mount, set collar, current dispersion plate, soil baffle plate, semi-cylindrical hill, end cap; It is characterized in that: on the leaching simulation column outer wall capacity index line is arranged, the other capacity sign value that indicates of capacity index line; End cover surface is provided with many micropores.
