Abstract
The utility model provides a be used for diagnostic earthworm normal position monitoring devices of soil ecological environment toxicity, relates to a soil ecological environment monitoring devices, the device is including box, lid, the bleeder vent that permeates water, nylon wire or stainless steel meshwork, handle, the device is two -layer inside and outside being, the outer cuboid box that be, device upper portion opening can be dismantled, six face evenly distributed of box bleeder vent that permeates water, install the inlayer for the size is equal to 100 outer mesh nylon wire or stainless steel meshwork, the outside of device is along installing two handles. The device utilizes the earthworm to do the on -the -spot diagnosis of polluting soil toxicity, provides economy, convenient, effectual analogue means, provides technical guarantee for obtaining reliable soil environment toxicity data.
Description
Technical field
The utility model relates to the ecological toxicity diagnostic device of soil environment, relates in particular to a kind of earthworm in-situ monitoring device for the diagnosis of soil ecology toxicity.
Background technology
In soil ecosystem, earthworm is one of most important person of perching. On the one hand, earthworm can be improved ventilation, water conservation and the draining of soil, improves the Nutrient Cycling speed of soil, regulates the composition of soil microflora, improves the function of soil ecosystem; On the other hand, earthworm has special status in terrestrial ecosystems, it be a lot of animals as the food of muroid, birds etc., therefore in some sense, it is to connect pedosphere and atmospherical important step.
In the ecological toxicity diagnosis research of soil pollution, because earthworm is widely distributed, and soil pollution is coerced more responsive, thereby earthworm becomes one of important biomolecule index of soil pollution condition detection, is also the model organism of recommendation in many ecological toxicity international standards. At present, about the angioedema of soil pollution diagnosis research of science, be mainly that the indexs such as survival rate (or death rate), earthworm body weight gain rate and earthworm breeding potential taking earthworm change response as research object, check the situation of soil pollution. But, above-mentioned correlative study mainly depends on laboratory dystopy diagnostic means at present, but along with the deep development of the ecological toxicity diagnosis research of soil pollution and practical application, urgent need is carried out the research that is diagnosed as means with original position toxicity, therefore, it is particularly important that design more adapts to carry out the experimental provision of earthworm original position eco-toxicity diagnosis, and this is to ensure that research carries out smoothly and obtain the most important condition of authentic data, and this is also the main target of this patent.
Summary of the invention
The purpose of this utility model is to provide a kind of earthworm in-situ monitoring device for the diagnosis of soil ecology toxicity, this device utilizes earthworm to do the field diagnostic of contaminated soil toxicity, economic, convenient and effective analogue means is provided, provides technical guarantee for obtaining reliable soil environment toxicity data.
The purpose of this utility model is achieved through the following technical solutions:
For an earthworm in-situ monitoring device for soil ecology toxicity diagnosis, described device comprises casing, lid, water-permeable and air permeable hole, nylon wire or stainless (steel) wire, handle; Device is for inside and outside two-layer, and skin is cuboid casing, and device upper opening is also detachable, and six faces of casing are uniformly distributed water-permeable and air permeable hole, and device internal layer is that size is equal to outer field 100 order nylon wire or stainless (steel) wires; The outer edge of device is provided with two handles.
Described a kind of earthworm in-situ monitoring device for the diagnosis of soil ecology toxicity, described outer layer box body long for 20-40cm, wide be 20-40cm, the high 20-50cm of being.
Described a kind of earthworm in-situ monitoring device for the diagnosis of soil ecology toxicity, cubical six faces of the described device evenly aperture of punching are 2.5mm, aperture spacing is 3cm.
Advantage of the present utility model and effect are:
The utility model, for the field diagnostic that utilizes earthworm to carry out contaminated soil toxicity provides economic, convenient and effective analogue means, provides technical guarantee for obtaining detecting more reliably soil environment toxicity data.
Brief description of the drawings
Fig. 1 is composition schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is elaborated.
Embodiment
As shown in Figure 1, mark in figure: 1, casing; 2, lid; 3, water-permeable and air permeable hole, 4, nylon wire or stainless (steel) wire; 5, handle.
A kind of earthworm in-situ monitoring device for the diagnosis of soil ecology toxicity of the utility model, device is divided into inside and outside two-layer, outer material of main part is lucite or plastics, be shaped as cuboid casing, casing long for 20-40cm, wide be 20-40cm, high be 20-50cm, device upper opening detachably, cubical 6 faces evenly punch, aperture 2.5mm, spacing is 3cm. Device internal layer is that size is equal to outer field 100 order nylon wire or stainless (steel) wires. Outer edge at device is provided with 2 handles.
When experimental implementation, experimental provision is taken to the place that need to carry out toxicity diagnosis, dig out the soil approaching with device volume in monitoring point, remove original earthworm in soil, pack soil into culture apparatus, by the earthworm embedding device of right quantity, build lid, again device is put back to monitoring site, and need to carry out short-term or long term monitoring according to experiment. Observation process in the wild scene carries out, and is conducive to obtain more reliable experimental result.
