Description
Technical Field
[0001] This utility model patent relates to the field of agricultural cultivation devices, specifically a culture barrel that is convenient for monitoring the content of soil microorganisms. Background Art
[0002] Plants used in agricultural research are usually grown in culture barrels. The appearance of existing culture barrels is similar to that of ordinary household buckets. After the plants have been planted in the culture barrels for a period of time, the soil around the roots of the plants needs to be tested for microorganisms. The existing method of taking soil is to dig out the entire plant root system from the culture barrel and then take the root soil for testing. However, this method of taking soil is cumbersome to operate, and digging out the entire plant will damage the plant's root system, affecting the plant's subsequent growth. On the other hand, this method of taking soil is not convenient for monitoring the microbial conditions of the root soil during different growth cycles of the plant. Utility Model Content
[0003] The utility model aims to provide a culture barrel that is convenient for monitoring the content of soil microorganisms, and is mainly used to solve the technical problems in the prior art that soil extraction is troublesome and easily damages the root system of plants, thereby affecting the subsequent growth of plants.
[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0005] A culture barrel for monitoring soil microbial content comprises a barrel body, an observation port is provided on the side of the barrel body, and a covering device for closing the observation port is hinged at the observation port.
[0006] Beneficial effects of the utility model:
[0007] The existing method of taking soil requires digging out the entire plant's root system from the bucket, which is cumbersome to operate and easily damages the plant's root system. However, this solution opens an observation port on the side of the bucket. The operator only needs to open the cover device and then take out the soil from the plant's root system through the observation port. There is no need to dig out the entire plant, and it will not cause serious damage to the plant's root system. In summary, this solution solves the technical problems in the existing technology that taking soil is cumbersome to operate and easily damages the plant's root system, affecting the subsequent growth of the plant.
[0008] Preferably, at least two partitions are fixed vertically in the barrel body, and a number of through holes for roots to pass through are distributed on the partitions. The at least two partitions divide the internal space of the barrel body into a number of vertically distributed monitoring areas; the covering device includes a number of door panels hinged at the observation port of each monitoring area and used to close the observation port of the monitoring area. In this solution, because the roots of some plants grow longer, the barrel body is divided into a number of vertically distributed monitoring areas, and different monitoring areas can be opened accordingly to sample and test the soil near the roots at different depths; at the same time, according to the cycle of the root system (the longer the growth time, the longer the root length), monitoring areas of different depths can be opened accordingly, and the soil of roots with different growth cycles can be sampled to monitor the microbial content in the soil; at the same time, when only the soil in the middle monitoring area is taken, the partition provided can provide support for the upper soil to prevent the upper soil from collapsing.
[0009] Preferably, several of the door panels are provided with mounting holes, in which soil sampling devices are installed. The soil sampling devices include a fixed tube and a sampling tube that are sequentially sleeved from the outside to the inside and rotatably connected to each other. The fixed tube passes through the mounting hole and its end is radially inserted into the interior of the barrel body. The fixed tube and the mounting hole are detachably connected. The side walls of the fixed tube and the sampling tube are provided with sampling ports that can communicate with each other. In this solution, the fixed tube and the sampling tube are rotated so that the sampling ports of the sampling tube and the fixed tube overlap and face upward. The outer wall of the barrel body is gently tapped. At this time, the soil falls through the sampling port into the innermost sampling tube due to gravity and vibration. The sampling tube is then pulled out, taking out the soil that has fallen into the sampling tube. After sampling is completed, the sampling tube is reinserted into the fixed tube and rotated so that the sampling ports of the sampling tube and the fixed tube are offset until they do not overlap at all.
[0010] This solution combines a soil sampling device with a door panel. Its characteristics are that when the door panel is not opened, the fixed tube is always installed in the installation hole. The sampler is installed in the barrel before planting and is always with the root system after planting. During the sampling process, only the sampling tube is movable. The growth of the plant root system will not be affected when the sampling tube is pulled out or inserted into the fixed tube. When no sampling is taken, the sampling ports of the sampling tube and the fixed tube are staggered to prevent the roots from growing into the soil sampling device. The soil sampling device directly penetrates into the soil inside the barrel. The sampling range can be adjusted according to the size and position of the sampling port. According to actual needs, multiple sampling ports can be designed to perform point sampling. Sampling is very convenient and will not damage or interfere with the growth of the plant root system.
[0011] Preferably, both ends of the fixed tube are open; the end of the sampling tube inserted into the fixed tube is closed. After sampling, the sampling tube is pulled out of the fixed tube, and some soil falls into the fixed tube. When the sampling tube is reinserted, the closed end of the sampling tube can push the soil in the fixed tube toward the open end of the fixed tube, preventing clogging of the fixed tube.
[0012] Preferably, a first retaining ring is fixed to the outer circumference of the end of the fixed tube located outside the barrel; a second retaining ring is fixed to the outer circumference of the end of the sampling tube located outside the barrel; the second retaining ring contacts the end of the first retaining ring. In this embodiment, the first retaining ring serves to limit the insertion depth of the fixed tube and prevent the fixed tube from being completely inserted into the barrel and unable to be removed, while the second retaining ring serves to limit the insertion depth of the fixed tube and prevent the fixed tube from being completely inserted into the fixed tube and unable to be removed.
[0013] Preferably, the ends of the first and second stop blocks away from the barrel body are each marked with a mark for marking the direction of the sampling port opening. In this solution, by adjusting the positions of the marks on the first and second stop blocks, the relative positions of the fixed tube and the sampling port of the sampling tube can be determined and adjusted.
[0014] Preferably, the fixing tube is rotatably connected to the mounting hole. In this solution, the fixing tube can be adjusted in the direction of the sampling port to sample soil from different directions. If soil from the side is difficult to enter the sampling tube, a thin long wire can be used, the end of the wire bent into a hook shape, inserted into the sampling tube, and the soil from the side can be scooped into the sampling tube and taken out.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figure 1 、 Figure 2 As shown, a culture barrel for monitoring soil microbial content includes a barrel body 1 with an observation port on the side of the barrel body 1. Two partitions 11 are vertically fixed in the barrel body 1, and a plurality of through holes 111 for roots to pass through are distributed on the partitions 11. The two partitions 11 divide the internal space of the barrel body 1 into three vertically distributed monitoring areas; the observation port covers all monitoring areas, and the covering device includes three door panels 2 hinged at the observation ports of the three monitoring areas and used to close the observation ports of the monitoring areas.
[0023] Because the roots of some plants grow longer, the barrel body 1 is divided into three vertically distributed monitoring areas. Different monitoring areas can be opened accordingly to sample and test the soil near the roots at different depths. At the same time, monitoring areas of different depths can be opened according to the cycle of the root system (the longer the growth time, the longer the root system length), and soil of roots with different growth cycles can be sampled. At the same time, when only the soil in the middle monitoring area is taken, the provided partition 11 can provide support for the upper soil to prevent the upper soil from collapsing.
[0024] like Figure 1 As shown, the three door panels 2 are provided with mounting holes, and the soil sampling devices 3 are installed in the mounting holes; Figure 4 、 Figure 5As shown, the soil sampling device 3 includes a fixed tube 31 and a sampling tube 32 which are sequentially sleeved from the outside to the inside and rotatably connected to each other, both ends of the fixed tube 31 are open; one end of the sampling tube 32 is inserted into the fixed tube 31 and is closed; the fixed tube 31 passes through the mounting hole and is slidably connected to the mounting hole, and the end of the fixed tube 31 is radially inserted into the barrel body 1; the side walls of the fixed tube 31 and the sampling tube 32 are provided with sampling ports 4 which can be communicated with each other; the fixed tube 31 and the sampling tube 32 are rotated so that the sampling ports 4 of the sampling tube 32 and the fixed tube 31 overlap and face upward, and the outer wall of the barrel body 1 is gently tapped. At this time, the soil is Due to force and vibration, the soil passes through the sampling port 4 and falls into the innermost sampling tube 32. Then the sampling tube 32 is pulled out, and the soil fallen into the sampling tube 32 is taken out. After the sampling tube 32 is pulled out of the fixed tube 31, some soil will fall into the fixed tube 31. After the sampling is completed, the sampling tube 32 is inserted again. The end of the sampling tube 32 can push the soil in the fixed tube 31 toward the end opening of the fixed plate to prevent the fixed tube 31 from being blocked. At the same time, the sampling tube 32 is rotated so that the sampling port 4 of the sampling tube 32 and the sampling port of the fixed tube 31 are staggered until they are completely non-overlapping, thereby preventing the roots from extending into the sampling tube 32.
[0025] like Figure 3 As shown, a first limiting ring 311 is fixed to the outer circumference of one end of the fixing tube 31 located outside the barrel body 1; a second limiting ring 321 is fixed to the outer circumference of one end of the sampling tube 32 located outside the barrel body 1; the second limiting ring 321 contacts the end of the first limiting ring 311, and the second limiting ring 321 and the first limiting ring 311 are arranged to prevent the fixing tube 31 and the sampling tube 32 from being inserted too deeply and unable to be removed.
[0026] like Figure 3 As shown, the first limit block and the second limit block are both marked with a mark 5 on the end away from the barrel body 1 for marking the opening direction of the sampling port 4; by adjusting the position of the mark 5 on the first limit block and the second limit block, the relative position of the sampling port 4 of the fixed tube 31 and the sampling tube 32 can be determined and adjusted.
[0027] From the above, it can be seen that the technical principles of the present utility model are as follows:
[0028] After each monitoring area in the barrel body 1 is filled with soil, the door panels 2 are completely closed, and then the fixed tube 31 is inserted into the barrel body 1, and the sampling tube 32 is inserted into the fixed tube 31. By adjusting the positions of the marks 5 on the first limiting ring 311 and the second limiting ring 321, the sampling ports 4 of the fixed tube 31 and the sampling tube 32 are staggered.
[0029] Then, the plant to be studied is planted in the barrel body 1. During the growth process of the plant root system, the root system bypasses the fixed tube 31 and extends downward uniformly through the through hole 111 of the partition 11. When the researcher needs to take samples according to the growth cycle of the root system, he can rotate the sampling tube 32 so that the sampling port 4 of the sampling tube 32 coincides with the sampling port 4 of the fixed tube 31, and gently tap the outer wall of the barrel body 1. At this time, the soil passes through the sampling port 4 due to gravity and vibration and falls into the innermost sampling tube 32. Then the sampling tube 32 is pulled out, and the soil that has fallen into the sampling tube 32 is taken out for soil microbial content testing. After the sampling is completed, the sampling tube 32 is reinserted into the fixed tube 31, and the sampling tube 32 is rotated so that the sampling port 4 of the sampling tube 32 and the sampling port 4 of the fixed tube 31 are staggered until they do not coincide at all.
[0030] If researchers need to monitor the microbial content of root soil at different periods, they need to take soil regularly. Alternatively, they can use the soil sampler in this device to take soil repeatedly as needed without damaging the plant roots.
[0031] If the researcher's research project also includes observing the growth of the root system, he or she can also choose to pull out the soil sampling device 3, then open the door panel 2, and observe the growth of the root system. When sampling is needed, sampling can be done directly at the observation port, or the fixed tube 31 can be reinserted into the installation hole to take samples. This sampling method will slightly damage the plant root system, but because the root system has grown around the insertion position of the fixed tube 31 during growth, when the fixed tube 31 is inserted a second time at the same position, the damage to the plant root system is relatively small.
[0032] This device can be used in a variety of ways, and researchers can choose and adjust it according to their research needs.
[0033] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
