Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of biological research, in particular to a device for collecting underground biomass of crops. Background Art
[0002] The root system of crops is an important organ to ensure the normal growth of crops, especially under adverse conditions. Its ability to absorb underground nutrients and water directly determines the growth of crops and the establishment of communities. Existing studies have found that under adverse conditions, crops respond to adverse environmental conditions by changing root density, root length and root diameter to ensure the crop's own needs for water and nutrients. The root growth morphology and quality can directly reflect the crop's own adaptation to the growth environment. By observing the root morphology of crops, it can be explained that the crop's own adaptability under adverse environmental conditions can be explained. This has important ecological significance for studying the root growth laws of crops under adverse conditions.
[0003] The research on crop roots mainly adopts potting method and soil culture method to cultivate plants. The traditional potting method blocks the exchange of crop roots and soil substances to a certain extent, which has a significant restrictive effect on the growth of crop roots. Although the soil culture method can truly simulate the field environment, it is very difficult to remove the crop roots in the later stage. The crop roots cannot be completely removed and the root morphology is destroyed in the process of removal.
[0004] In view of this, an improvement scheme is designed for the existing structure and deficiencies, and the present utility model is proposed. Utility Model Content

[0026] By adopting the above technical solution, the utility model has the following beneficial effects:
[0027] The present application discloses a device for collecting underground biomass of crops. The device comprises a cylinder, a mesh and a mesh bag. The cylinder has a cavity, a top opening and a bottom opening, and the top opening and the bottom opening are both connected to the cavity. The mesh is arranged on the cylinder, and the mesh covers the bottom opening. The mesh bag can be contained in the cavity, and the mesh bag can be loaded into or taken out of the cavity. During the operation of the experiment, the cylinder is first buried in the field, and the cylinder and the mesh bag are filled with soil, and the crops are planted in the soil in the mesh bag. After the crops have been allowed to grow for a certain period of time, the cylinder, the mesh, the mesh bag and the crops inside are taken out of the field at the same time. The part of the crop located above the soil is cut off, and the soil in the cylinder is removed by vibration, cleaning and the like, and the crop root system with a complete and relatively clean shape remains in the mesh bag. The crop root system is used for the next step of observation and experiment to ensure that the results of the observation and experiment are more accurate.
[0028] Among them, the cylinder contains the mesh, net bag and the underground part of the crop in the cavity, making it more convenient to plant the collection device and the crop in the field and to take it out from the field. The mesh covers the bottom opening of the cylinder to prevent the root system from growing downward without restriction. At the same time, the root system can absorb moisture and nutrients from the soil outside the cylinder, which reduces the influence of the cylinder on the root growth to a certain extent. The crops are planted in the net bag, and the root system of the crops is basically located in the net bag. The net bag will not affect the root system's absorption of moisture and nutrients from the soil outside the net bag, nor will it limit the growth of the root system. When taking out the roots, the net bag is taken out together with the roots at the same time, which protects the root system and prevents the root system from breaking. During the root cleaning process, the roots are located in the net bag, and the net bag can easily discharge the internal soil through the mesh holes and prevent the loss of the roots in the net bag, which can ensure the complete shape of the root system after cleaning. Therefore, the underground part of the crop obtained using the crop underground biomass collection device of this patent application not only greatly reduces the inhibition during growth, but also maintains its complete shape after being obtained and cleaned, thereby ensuring that the conclusions drawn from subsequent crop root system research are more accurate.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0044] See also Figures 1 to 8 As shown, the embodiment of the present application provides a device for collecting underground biomass of crops, including a cylinder 1, a mesh 2 and a mesh bag 3. The cylinder 1 has a cavity, a top opening and a bottom opening, and the top opening and the bottom opening are both connected to the cavity. The mesh 2 is arranged on the cylinder 1, and the mesh 2 covers the bottom opening. The mesh bag 3 can be accommodated in the cavity, and the mesh bag 3 can be loaded into or taken out of the cavity. During the operation of the experiment, the underground biomass collection device of the present application is first buried in the field, and the cylinder 1 and the mesh bag 3 are filled with soil, and the crops are planted in the soil in the mesh bag 3. After giving the crops a certain growth time, the cylinder 1 together with the mesh 2, the mesh bag 3 and the crops inside are taken out of the field at the same time. Cut off the part of the crop above the soil, remove the soil in the cylinder 1 by vibration, cleaning, etc., and the net bag 3 will have a complete and relatively clean crop root system. The crop root system is used for the next step of observation and experiment to ensure that the results of the observation and experiment are more accurate.
[0045] Among them, the mesh 2, the mesh bag 3 and the underground part of the crop are all contained in the cavity of the cylinder 1, so that it is more convenient to plant the collection device and the crop in the field and to take it out from the field, and to a certain extent, the root system is restricted from creeping around. The mesh 2 covers the bottom opening of the cylinder 1 to prevent the root system from growing downward without restriction, and the root system can absorb the moisture and nutrients of the soil outside the cylinder 1, and to a certain extent, reduce the influence of the cylinder 1 on the root system growth. The crop is planted in the mesh bag 3, and the root system of the crop is basically located in the mesh bag 3. The mesh bag 3 will not affect the root system to absorb the moisture and nutrients of the soil outside the mesh bag 3, nor will it limit the root system growth. When taking the root, the mesh bag 3 is taken out together with the root system, and the root system is protected to prevent the root system from breaking. In the process of cleaning the root system, the root system is located in the mesh bag 3, and the mesh bag 3 can easily discharge the internal soil from the mesh hole, and prevent the root system in the mesh bag 3 from being lost, so as to ensure the complete morphology of the root system after cleaning. Therefore, the underground part of the crop obtained using the crop underground biomass collection device of the present application not only greatly reduces the inhibition during the growth process, but also maintains its complete shape after being obtained and cleaned, thereby ensuring that the conclusions drawn from subsequent research on the crop are more accurate.
[0046] The cylinder 1 needs to be buried in the soil and needs to be rust-resistant and corrosion-resistant. The cylinder 1 can be one of PPR pipes, PVC pipes, UPVC pipes, copper pipes, steel pipes, fiber pipes, composite pipes, galvanized pipes, etc. The cylinder 1 can be made of commonly used pipes on the market, and sleeves of different calibers and lengths can be selected according to the growth form of crop roots.
[0047] The mesh 2 needs to be buried in the soil and carry the soil and crops in the cylinder 1. It needs to have a certain strength, not easy to rust, and corrosion-resistant. The mesh 2 can be made of stainless steel, copper, aluminum, titanium alloy, polyethylene, polypropylene, nylon and other materials. The specifications of the mesh 2 can be selected according to the size of the crop root system. Preferably, the mesh 2 uses a 50-70 mesh mesh 2. Most preferably, the mesh 2 uses a 60-mesh nylon bottom screen. The 60-mesh nylon bottom screen is to prevent the roots from growing downward without restriction, retain the main roots in the mesh bag 3, and at the same time meet the exchange of moisture and nutrients between the roots and the soil outside the barrel. Reduce the influence of the sleeve on the growth of the root system to a certain extent.
[0048] The mesh bag 3 carries plants and soil, and is convenient for cleaning the internal soil. It needs to have the characteristics of high strength, wear resistance, acid and alkali resistance and certain flexibility. The mesh bag 3 can be made of polyethylene, polypropylene, nylon and other materials. The specifications of the mesh bag 3 can be selected according to the size of the crop root system. Preferably, the mesh bag 3 uses a 30-50 mesh mesh bag 3. Most preferably, the mesh bag 3 uses a 40-mesh nylon mesh bag 3. The 40-mesh mesh bag 3 is convenient for cleaning the root system in the later stage. After the mesh bag 3 is placed in the pool, the soil is filtered out. The nylon material is used, as long as the nylon mesh bag 3 has good corrosion resistance, the material is strong and durable, and it will not be damaged after being buried in the soil for a period of time, and the roots will not be lost when the soil on the roots is cleaned.
[0049] In some possible implementations, the mesh area of the mesh sheet 2 is smaller than the mesh area of the mesh bag 3. Some fine roots of crops need to pass through the mesh bag 3 to grow and absorb water and nutrients, so the mesh area of the mesh bag 3 is selected to be relatively large. The mesh sheet 2 should prevent the root system from growing downward without restriction and should carry the soil and plants in the cylinder 1, so the mesh area of the mesh sheet 2 is relatively small. Preferably, the mesh number of the mesh bag 3 and the mesh number of the mesh sheet 2 are in a ratio of 2:3.
[0050] In some possible implementations, the net bag 3 has a net bag opening, and a binding rope 4 is provided on one side of the net bag 3 near the net bag opening. The net bag opening is located on the side of the cylinder 1 near the top opening, which facilitates the planting of crops from the net bag opening into the net bag 3. After the net bag 3 is taken out of the cylinder 1, the above-ground part of the crop is cut off, and the binding rope 4 is pulled in to tighten the net bag opening, which can prevent the loss of the root system caused by the root system flowing out of the net bag opening during the cleaning of the root soil in the net bag 3.
[0051] The binding rope 4 can be a rope body separated from the net bag 3 or a rope body connected to the net bag 3 at one end. The binding rope 4 can be wound around the bottom of the net bag opening and tightened to tighten the net bag opening. Alternatively, the net bag 3 is provided with a folded edge at the net bag opening, the bottom of the folded edge is connected to the net bag 3, a strip-shaped gap is formed between the folded edge and the net bag 3, the middle section of the binding rope 4 can be movably inserted into the gap, and the two ends of the binding rope 4 are exposed in the gap. The net bag opening can be tightened by pulling the two ends of the binding rope 4.
[0052] In some possible implementations, such as Figure 2 , Figure 8 As shown, the crop underground biomass collection device also includes a hard support skeleton 5, which is arranged on the cylinder 1 and covers the bottom opening, and the hard support skeleton 5 has meshes. The mesh 2 is supported on the hard support skeleton 5, and the mesh area of the hard support skeleton 5 is larger than the mesh area of the mesh 2. The hard support skeleton 5 is mainly used to support the mesh 2 and prevent the mesh 2 and the net bag 3 from falling off from the sleeve during the excavation process. Among them, the hard support skeleton 5 needs to be buried in the soil and carry the soil and crops in the cylinder 1. It needs to have a certain strength, not easy to rust, and corrosion-resistant. The hard support skeleton 5 can be made of stainless steel, copper, aluminum, titanium alloy, and other materials. The hard support skeleton 5 can be prepared by staggered welding of metal wires.
[0053] In some possible implementations, such as Figure 2 , Figure 3 As shown, the cylinder 1 is provided with an inner flange 6 around the edge of the bottom opening, and the rigid support frame 5 is located in the cavity and supported on the inner flange 6. The inner flange 6 provides a support point and a supporting force for the rigid support frame 5, ensuring that the rigid support frame 5 is stably arranged and will not fall off from the sleeve during use.
[0054] In some possible implementations, the rigid support frame 5 includes an outer ring 51 and an inner net 52 connected to the outer ring 51, the outer ring 51 and part of the inner net are supported on the inner flange 6, and the inner net 52 is formed by staggered welding of metal wires. The outer ring 51 and the inner net 52 can be connected by welding.
[0055] In some possible implementations, such as Figures 2 to 5 As shown, a handle assembly 7 is provided on the cylinder 1, and the handle assembly 7 is located near the top opening of the cylinder 1. The handle assembly 7 is convenient for holding and applying force when the entire device is taken out of the soil. The handle is provided at the upper edge of the cylinder 1, so that the handle can be exposed from the soil without digging too deep in the later stage.
[0056] In some possible implementations, along the axis direction of the cylinder 1, the handle assembly 7 does not protrude from the top opening of the cylinder 1. When planting crops, the cylinder 1 is completely covered with soil. If the handle assembly 7 is not higher than the cylinder 1, when planting and landfilling, the cylinder is covered, that is, the handle assembly is also covered, and there is no need to do deeper landfilling, and the planting and removal processes are more convenient.
[0057] In some possible implementations, the handle assembly 7 includes handle rings 71 located on opposite sides of the top opening. When the cylinder 1 is taken out of the soil, the handle rings 71 on both sides are held at the same time, and force is applied simultaneously or alternately on both sides, so that the process of taking the cylinder 1 out of the soil is smoother.
[0058] In some possible implementations, the handle assembly 7 and the barrel 1 are integrally formed. The handle assembly 7 can be made of the same material as the barrel 1 and can be integrally formed by injection molding. The handle ring 71 can be a single piece, and plastic can be injected into a mold using a high-pressure injection molding machine and closely attached to the surface of the handle ring 71 coated with special ink. After a certain pressure and temperature treatment, the plastic and the handle ring 71 are tightly combined into one, and finally an integrated plastic composite part is formed.
[0059] Alternatively, the handle assembly 7 and the barrel 1 are separate parts, and the handle assembly 7 is fixed to the barrel 1. The handle assembly 7 can be connected to the barrel 1 by means of snap connection, fastener connection, plug connection, etc.
[0060] In some possible implementations, such as Figure 3 and Figure 4 As shown, the connection mode of the handle assembly and the cylinder body can be that the end of the cylinder body 1 located at the top opening is provided with an arc-shaped outer flange 8, and the handle assembly 7 includes a collar 72, and the two opposite sides of the collar 72 are respectively provided with handle rings 71. The collar 72 is sleeved on the cylinder body 1, and the collar 72 is located on the side of the outer flange 8 close to the bottom opening, and the outer diameter of the outer flange 8 is greater than the inner diameter of the collar 72. An installation groove is formed between the outer flange 8 and the cylinder body 1, and the collar 72 is located in the installation groove. Avoidance grooves are provided on both sides of the outer flange 8, and one end of the handle ring 71 extends out of the avoidance groove and is connected to the collar 72. The cylinder body is made of metal material to facilitate the above arrangement.
[0061] like Figure 5 and Figure 6 As shown, the handle assembly is connected to the barrel in such a way that the barrel 1 is provided with a horizontal outer flange 8 at one end of the top opening, and the collar 72 is limited below the outer flange. This arrangement is convenient when the barrel is made of PVC.
[0062] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the solution of the utility model.
