Abstract
The invention relates to an earthworm feeding device for in-situ monitoring safety of soil environment, and belongs to the field of environment protection. The device can be used for overcoming the defect that a traditional earthworm toxicity experiment only can be simulated inside a laboratory; and a device for earthworm to in-situ monitor the soil environment is built. The earthworm feeding device is characterized an opening is formed at the upper part of a rectangular stainless steel box body, wherein a folding escape sheet is arranged at the opening; a plurality of water and gas holes are distributed on the four sides and bottom part of the box body; closely woven flax is covered inside the box body; and a handle for transporting is arranged on the upper part of the exterior of the box body. The device has a delicate design and strong operability, and is a breakthrough innovation on soil environment toxicology research, thus filling a blank of the field at home and abroad, being simple in manufacturing, low in cost and capable of being extensively applied to the field of experiment research.
Description
Technical field:
The present invention relates to a kind of earthworm breeding device, more specifically a kind of earthworm breeding device for the safe in-situ monitoring of soil environment belongs to field of environment protection.
Background technology:
Soil is the basis that the mankind depend on for existence, and soil quality situation is closely bound up with human health and development.Along with industry and oil-agriculture fast development, a large amount of dischargings of the pollutants such as trade waste, chemical fertilizer and agricultural chemicals and using cause to soil environment quite to seriously influence, and also bring potential risk to human health.Therefore, be very necessary to evaluation and the monitoring of soil environment safety.
There is important Ecology Action in the Soil of Earthworms system, as promoting that microorganism and other soil animal are movable, broken and decomposing litter, increase soil fertility etc.Also be one of important indicator organism of soil pollution situation simultaneously.So earthworm more and more is used as model animal and studies soil environment, all adopted earthworm as tested object from international ISO to domestic multiple standards method.
At present, the technology of utilizing earthworm to carry out the soil environment safety evaluation is mainly carried out in the laboratory, the feeding environment of earthworm and compare or can not simulate fully with open-air actual conditions with the interaction of tester.So in the urgent need to a kind of method of the soil environment of in-situ monitoring in the open air safety, so that evaluation result is more reliable and have a convincingness.
Summary of the invention:
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the open-air earthworm breeding device of a cover, solved and can not utilize for a long time animal to carry out the difficult problem of the safe in-situ monitoring of soil environment.
Technical scheme of the present invention is: the main body of raising device is high 35-40cm, long 25-30cm, and the cuboid casing of wide 25-30cm, material is highstrenghtpiston or stainless steel, and is firm and corrosion-resistant.
The raising device opening part is equipped with collapsible putting and escapes sheet, prevents that earthworm from runing away, and bends inwards during monitoring, outwards opens handled easily when taking out earthworm.
The inboard good close burlap of knitting of water-permeable and air permeable that covers of raising device prevents that earthworm from runing away.
Four sides and the bottom surface of raising device are distributed with a large amount of holes, have guaranteed the abundant exchange of raising device and external substance.
Raising device respectively has a handle near the opening part both sides, the operation during convenient sampling.
Beneficial effect of the present invention: the invention provides a kind of earthworm breeding device for the safe in-situ monitoring of soil environment, the breakthrough innovation that belongs to the soil environment monitoring field, the design of this device is ingenious, workable, to make simple, with low cost in addition, can be widely used in soil environment security study field.
Description of drawings:
Fig. 1 is perspective view of the present invention.
Among the figure: 1-raises casing, anti-sheet, close burlap, 4-water-permeable and air permeable hole, the 5-handle knitted of 3-escaped of 2-
Embodiment:
Choose the place that needs monitoring, dig out the soil close with the raising device volume, screen one time, confirming does not have behind other earthworm soil to be inserted raising device, selects 10～20 of the earthworms of testing usefulness, puts into raising device.If originally the monitored area has vegetation to cover, then can will continue plantation in original vegetation transplanting and the raising device carefully.At last whole raising device is buried go back to original position, the anti-sheet of escaping closes.
If soil is more dried, can sprays appropriate amount of purified water and make box inside burlap and ground moistening, so that earthworm conforms fast.Just can carry out short-term or long term monitoring according to the different experiments needs afterwards.
When sampling experiment, can easily raising device be shifted out with handle, will put and escape sheet and be folded into open mode, pour out inner soil, statistics earthworm and earthworm cocoon quantity, and collect earthworm and carry out further experiment and detect.
Whole observation process fully in the open air original position carries out, and has at utmost guaranteed authenticity and the reliability of experimental data.
