Abstract
The utility model discloses an undisturbed soil culture vessel containing a top cover, which effectively controls the depth of soil sampled by the undisturbed soil culture vessel in the field through scales on a sampling container so that the sampling depths on the whole test area or sampling points of each test area can be consistent. More importantly, the vessel is provided with the cover; therefore, not only the purpose of satisfying test demands can be achieved, but also convenience is provided for marking and perceiving; in addition, a filter film can be prevented from being bitten and destroyed by animals such as sheep and the like; moreover, the added top cover and the filter film can be used for a plurality of times; therefore, resources can be saved.
Description
Technical field
The utility model relates to a kind of original-state soil culture vessel, concrete relates to a kind of containers of soil that comprises top cover.
Background technology
Ecological as the system science of a research biological (comprising the mankind) with the relation of environmental interaction, in solving significant problem processes such as current global resource problem and environmental problem, growing growth is got up.Continuous development innovation along with science and technology; Ecological knowledge and theory have been penetrated into each scientific research field; The research degree of depth and range obtain expanding day by day, and research means and method are also brought in constant renewal in, and move towards quantification and smart quantitative research day by day from traditional qualitative or sxemiquantitative research.Nearly decades, no matter ecology still is being on research method, all to have obtained significant progress in theory.
Ecology derives from biology; Its research object is the relation between biology and the environment; Promptly must be through field observation and investigation; Be familiar with and answer each species ecology process and inherent mechanism thereof by the test figure of obtaining, its related experiment technical method is through the whole processes such as analysis-by-synthesis of open-air ECOLOGICAL ENVIRONMENTAL MONITORING, ecological sample collecting and preservation, sample analysis indoor measurement and data.Therefore, relate to the accuracy of the open-air sampling method of large-scale key subjects research, can be directly connected to the order of accuarcy of test gained data, even directly influence the success or failure of problem.
Location observation and original place experiment are to investigate certain population or the structure function of group and the space-time dynamic of its habitat mutual relationship; Not only help to illustrate the mechanism of action of some environmental factor, can also be as the reference and the foundation of ecological controlled experiment or ecological emulation.At present; " original position cultural method " is exactly the commonly used open-air cultural method of studying element (mainly being carbon and nitrogen) mineralization process under certain external environmental condition; The most pvc pipes that adopt of its culture vessel circulate with ambient atmosphere in order to make inner air tube mutually, cover with filter membrane above; Tie up with bungee simply again, not have other any relevant control measure.It is thus clear that above-mentioned whole test technical method is not well controlled, the practical implementation process seems coarse, and the security of experiment can not get guaranteeing that the test institute data of surveying instability reliably.
The utility model content
The purpose of the utility model is to design a kind of original-state soil culture vessel, makes field soil undisturbed soil sample culture experiment carry out smoothly, guarantees the accuracy of experiment gained data.
At first, control effectively, make that sampling depth reaches consistent on the sampling spot of whole test district or each test site through the depth of soil of the scale on the sampling container to the open-air sampling of original-state soil culture vessel.
Secondly, sampling container is added a cover processing, can reach and satisfy the required purpose of experiment, also be convenient to sign and discover, can also prevent to herd sheep and only wait animal that gnawing of filter membrane neighed and destroy.
At last, the be also advantageous in that added lid and the filter membrane of the utility model all can repeatedly utilize, and save resource.
To achieve these goals, the utility model is taked following technical scheme:
The utility model relates in one aspect to a kind of original-state soil culture vessel; It comprises original-state soil sampling container and top cover; It is characterized in that described soil sample container is the pipe of hollow; Its lower end wall is a wedge shape, and described top cover is the pipe of hollow, and its internal diameter is slightly larger than or equals the external diameter of soil sample container.
In an embodiment of the utility model, it further comprises filter membrane the soil culture vessel, and said filter membrane is between soil sample container and top cover.
In an embodiment of the utility model, distinct sign scale is arranged on the outer wall of said soil sample container.
In an embodiment of the utility model, being has the slit that allows rainwater to flow out on the top cover, and the slit that described permission rainwater flows out is symmetrically located on the cover wall.
In an embodiment of the utility model, the length of original-state soil sampling container is between the 100-140mm, and thickness is between 1-5mm, and external diameter is between 30-100mm.
In an embodiment of the utility model, the length of top cover is between 30-80mm, and wall thickness is 1-5mm, and internal diameter is between 30-100mm.
In an embodiment of the utility model, the slit length that allows rainwater to flow out on the top cover is between the 15-40mm, and width is between the 1-10mm.
In an embodiment of the utility model, the material of soil sample container and/or top cover is PVC.

Embodiment
Introduce the embodiment of the utility model below in conjunction with accompanying drawing, the utility model is elaborated.
(1), can control the degree of depth (the most 10cm of being of sampling depth) of sampling when being convenient to outer the sampling well at the visual and eye-catching scale of original-state soil sampling container marked.The long 120mm of entire container, external diameter are 50mm, wall thickness 3mm, and the lower end is whittled into the water chestnut wedge shape, and 50mm and 100mm place indicate eye-catching scale apart from the lower end, so that the control soil sample degree of depth in the practical implementation process in the open air.
(2) top cover that is designed is the stronger pvc pipe abutment ring of elasticity, and length is 50mm, and internal diameter is 50mm, and an end leaves two little openings, and opening length is 25mm, and wide is 1mm.The osculum that is designed makes exactly and is stored in that rainwater successfully flows out in the top cover, can not keep the sampling container inner air and outer air unblocked because of rainfall is stranded in the top cover always.
(3) top cover exposes face of land 50mm after being placed on sampling container, so that discover, also can reduce the weathering speed of filter membrane effectively when regularly taking a sample.Simultaneously, herd sheep and only wait animal also can not gnaw to neigh and step on brokenly filter membrane, guarantee that experiment carries out smoothly.
(4) in the practical operation in the open air, sampling container vertically is pressed into rapidly in the soil, can adds a cover processing conveniently, convenient and swift, time saving and energy saving, safe and reliable.
On two dissimilar grazing meadows in zone of Desert Steppe in Inner Mongolia and typical grassland, carried out the long run test sampling in 2 years, during whole test; All original position soil culture vessel sampling depths are unanimity; Added top cover is all excellent, and neither one is herded sheep and only waited animal to destroy, and can reuse fully; And used filter membrane can use more than two months (sample interval is one month) at least, and open-air practice effect is obvious.
