Description

Technical Field

[0001] This invention relates to the fields of ecology, forestry and soil science research technology, and in particular to a soil experimental net bag that is resistant to rodent bites. Background Technology

[0002] In ecological and soil science research, the decomposition processes of soil organic matter (such as the decomposition of plant fine roots and litter) and soil biology studies are crucial for understanding the carbon cycle and nutrient dynamics of ecosystems. Currently, the most commonly used research method is the "bubble method," which involves placing the sample to be studied (such as fine roots, litter, soil, etc.) into a mesh bag made of a specific material (such as nylon, polyester, etc.), burying it in the soil, and periodically removing it to measure its changes.

[0003] However, existing mesh bags of this type have a significant drawback: poor resistance to chewing. In field experiments, rodents such as rats can easily bite through the mesh bags, consuming or damaging the samples inside, leading to severely distorted experimental data or even complete experimental failure. This not only wastes time and money but also affects the accuracy and reliability of scientific data.

[0004] In existing technologies, although some studies have attempted to use more robust ordinary metal mesh, ordinary metal mesh is prone to corrosion, and if the mesh size is too large, it is not suitable for studying fine roots or small litter (samples are easily leaked out); if the mesh size is too small, it is costly and difficult to manufacture. Therefore, there is an urgent need for a new type of mesh bag structure that can effectively prevent rodent gnawing without affecting the normal interaction between the sample and the soil. Summary of the Invention

[0005] The purpose of this invention is to provide a rodent-proof soil experimental net bag to solve the problems existing in the prior art, aiming to ensure that field bag burial experiments are not disturbed by rodents, and to improve the success rate of experiments and the accuracy of data. To achieve the above objectives, the present invention provides the following solution: The present invention provides a rodent-proof soil experimental net bag, comprising: An outer mesh bag is made of flexible stainless steel fiber blended mesh with a mesh size of 10 mm or less. An inner mesh bag is provided inside the outer mesh bag. The inner mesh bag is made of dense chemical fiber mesh with a mesh size of 2 mm or less. The inner mesh bag is used to hold experimental samples.

[0006] Preferably, a flexible tube is fixedly connected to the inner mesh bag, and a sealing pull rope is threaded through the tube.

[0007] Preferably, an intermediate isolation mesh bag is provided between the outer mesh bag and the inner mesh bag, and the intermediate isolation mesh bag is made of microporous polytetrafluoroethylene film or biodegradable microporous membrane.

[0008] Preferably, a net cage is provided outside the outer mesh bag, the net cage including a cage body and an upper cover, the upper cover being fastened to the cage body.

[0009] Preferably, a long clip is detachably connected to the outer mesh bag.

[0010] Preferably, the intermediate isolation mesh bag is detachably connected to a long clip.

[0011] Preferably, a label is fixedly attached to the outer mesh bag.

[0012] This invention discloses the following technical effects: In this device, the experimental sample is placed in the inner mesh bag. The experimental sample can be fine roots, litter, or undisturbed soil. Then, the inner mesh bag is placed inside the outer mesh bag, and the device is buried in the target soil layer. After the predetermined experimental time, the entire device is dug out, and the remaining sample in the bag is taken out for analysis. The outer mesh bag is made of flexible metal composite material, which rodents cannot bite through or damage. Field experiments have proven that it can effectively resist common predators such as field mice and house mice, and can also prevent corrosion. The inner mesh bag allows water, microorganisms, and small to medium-sized soil animals to pass through freely. This invention can effectively resist the teeth of rodents such as rats, fundamentally solving the problem of sample destruction, and can be widely used in various research scenarios such as fine roots, litter, and soil samples.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figure 1-3 This invention provides a rodent-proof soil test net bag, comprising: Outer mesh bag 1 is made of flexible stainless steel fiber blended mesh with a mesh size of less than or equal to 10 mm. An inner mesh bag 2 is set inside the outer mesh bag 1. The inner mesh bag 2 is a dense chemical fiber mesh with a mesh size of less than or equal to 2 mm. The inner mesh bag 2 is used to hold experimental samples.

[0018] In this apparatus, the experimental sample is placed in the inner mesh bag 2. The experimental sample can be fine roots, litter, or undisturbed soil. Then, the inner mesh bag 2 is placed inside the outer mesh bag 1, and the apparatus is buried in the target soil layer. After the predetermined experimental time has elapsed, the entire apparatus is excavated, and the remaining sample inside the bag is taken out for analysis.

[0019] The outer mesh bag 1 is made of flexible metal composite material, which rodents cannot bite through or destroy. Field experiments have proven that it can effectively resist common predators such as field mice and house mice, and can also prevent rust. The inner mesh bag 2 has a mesh size of less than or equal to 2mm, which is used to contain experimental samples and prevent them from leaking out, while allowing water, microorganisms and small and medium-sized soil animals to pass through freely.

[0020] The design has been further optimized by attaching a soft tube 3 to the inner mesh bag 2, and a sealing rope 4 is threaded through the tube.

[0021] The sealing drawstring 4 makes it easy to seal the inner mesh bag 2 to prevent the experimental sample from leaking out.

[0022] To further optimize the design, an intermediate isolation net bag 5 is provided between the outer net bag 1 and the inner net bag 2. The intermediate isolation net bag 5 is made of microporous polytetrafluoroethylene film or biodegradable microporous membrane.

[0023] The intermediate isolation net bag 5 prevents the loss of fine sample particles (such as crushed litter and fine root debris) due to disturbance during the initial burial stage, while allowing water vapor and dissolved nutrients to diffuse freely. The intermediate isolation net bag 5 can be used selectively depending on the experimental objective; for example, it can be omitted when studying the decomposition of a whole area of ​​litter.

[0024] The scheme is further optimized by adding a net cage to the outer mesh bag 1. The net cage includes a cage body 6 and an upper cover 7, with the upper cover 7 fastened to the cage body 6.

[0025] The mesh openings of the cage body 6 and the top cover 7 are in the range of 10mm-30mm to prevent rodents such as rats from entering.

[0026] The design has been further optimized by adding a long clip 8 that can be detachably connected to the outer mesh bag 1.

[0027] Long strip clip 8 is used to seal the outer mesh bag 1.

[0028] The design has been further optimized by adding a long clip 9 that can be detachably connected to the intermediate isolation net bag 5.

[0029] Long strip clip 29 is used to seal the intermediate isolation net bag 5.

[0030] The design has been further optimized by attaching a label 10 to the outer mesh bag 1.
