Description

Technical Field

[0001] The invention relates to the technical field of plant test devices, and in particular to a test device for rapid identification of salt-alkali tolerant plants. Background Art

[0002] Many halophytes are the only plants that can grow normally on saline soil. They have always played an important role in the development and utilization of saline soil and in maintaining ecological balance. Therefore, planting salt- and alkali-tolerant halophytes is one of the important methods for saline-alkali land restoration. Before halophytes are put into saline-alkali land improvement projects, the salt- and alkali-tolerant abilities of the plants themselves need to be tested and identified to ensure that this type of halophyte can survive successfully in the saline soil of the designated area.

[0003] When testing the salt-alkali resistance of halophytes, liquid culture medium and culture soil are often used to culture halophytes. For example, a field crop salt-alkali resistance simulation test device disclosed in Chinese patent publication number CN210221960U uses soil to plant halophytes. Although directly using soil to cultivate plants can make the identification results closer to the actual situation, solid soil is difficult to reversely reduce salinity as flexibly and quickly as liquid culture medium. It is easy to take away a large amount of soil near the plant root system when fresh water washes salt, causing damage to the root system. For this reason, a test device for rapid identification of salt-alkali tolerant plants is proposed. Summary of the invention

Figure 3 As shown, the water inlet end of the soil cultivation basin 2 is fixedly installed with a water pumping pipe 4, one end of the water pumping pipe 4 extends to the inside of the salt water table 1 and is connected to the concentration regulating box. In this embodiment, the concentration regulating box inside the salt water table 1 is connected to an external water source and has multiple ports, which are respectively connected to multiple water pumping pipes 4. At the same time, multiple independent regulating boxes are arranged inside the concentration regulating box, which can provide salt water of different concentrations and can also directly provide clean water. The water outlet end of the infusion pump 3 is fixedly installed with a telescopic hose 5, as shown in FIG. Figure 4 As shown, one end of the telescopic hose 5 is fixedly mounted with a connecting pipe 9. Figure 3 As shown, the soil cultivation pot 2 is fixedly provided with a support pipe frame 6 around it, and an external drip pipe 7 is placed on the top of the support pipe frame 6. Figure 4 As shown, the tops of the four outer droppers 7 located at the same place are fixedly mounted with the same annular tube 8, one end of the connecting tube 9 is fixedly mounted on the side wall of the annular tube 8, and the bottom of the annular tube 8 is provided with a three-way cultivation tube 10, as shown in FIG. Figure 5As shown, the three-way cultivation tube 10 is located inside the soil cultivation basin 2, and the three bottom ends of the three-way cultivation tube 10 are rotatably mounted with two symmetrically arranged semicircular tube racks 11, and multiple soil-fixing mesh sheets 12 are fixedly mounted on the semicircular tube racks 11, such as Figure 4 As shown, three inner droppers 13 are fixedly installed on the inner wall of the top of the three-way cultivation tube 10. The three inner droppers 13 are evenly distributed along the axis of the three-way cultivation tube 10. The tops of the three inner droppers 13 are fixedly installed on the bottom of the annular tube 8. Figure 6 As shown, the bottom end of the inner dropper 13 located on the same side extends between the two semicircular tube racks 11, as shown in FIG. Figure 8 As shown, the inner drip tube 13 is located at one end of the semicircular tube frame 11 and has a plurality of evenly distributed drip holes 1301. Fig. 9 As shown, a salinity probe 14 is fixedly installed at one end of the inner dropper 13 located inside the semicircular tube frame 11. In this embodiment, a display screen is provided on one side of each soil cultivation pot 2. The three salinity probes 14 of the same group are gathered together through a signal cable and connected to the display screen to display the salinity of the soil near the plant roots in the current soil cultivation pot 2. Figure 8As shown, the tops of the two semicircular tube racks 11 on the same side are fixedly installed with magnetic strips 15 on one side close to each other; specifically, when the test device for rapid identification of salt-alkali tolerant plants is used for the first time, culture soil is first put into the soil culture pot 2, and a three-pronged tunnel is dug in the culture soil, and then the semicircular tube racks 11 at each end of the three-way culture tube 10 are opened, and culture soil is also put between the three-way culture tube 10 and the semicircular tube racks 11, and then plant seeds or sprouts are planted in the soil in the middle of the three-way culture tube 10, and then the three-way culture tube 10 is buried in the three-pronged tunnel, and the support tube racks 6 on both sides of the soil culture pot 2 will be exposed to the outside. The drip tube 7 is supported to hang the three-way cultivation tube 10 in the three-pronged tunnel. At this time, the soil is continued to be filled in the soil cultivation pot 2 so that the cultivation soil covers the semicircular tube frame 11 at the bottom. Then the above operation is repeated to complete the planting of plants and the placement of the three-way cultivation tube 10 in each soil cultivation pot 2. Finally, salt water of different concentrations can be extracted from the concentration regulating box through each infusion pump 3 and sequentially input into different soil cultivation pots 2 through the telescopic hose 5, the connecting pipe 9, the annular pipe 8, the outer drip tube 7 and the inner drip tube 13. The root system of the plant will spread in the three ports of the three-way cultivation tube 10 and the three groups of semicircular tube frames 11. The salinity and alkalinity of the plants can be tested by observing the growth conditions of the plants in the soil cultivation pots 2. By setting the three-way cultivation pipe 10, when it is necessary to adjust the salinity and alkalinity of the cultivation soil midway, the infusion pump 3 can deliver higher concentration of salt water to the soil of the soil cultivation pot 2 to increase the salinity and alkalinity of the cultivation soil, or directly deliver clean water to the soil cultivation pot 2 to reversely reduce the salinity and alkalinity, so as to quickly determine the specific salinity range corresponding to the salt-alkali tolerance of the plant of this category. At the same time, the three-way cultivation pipe 10, the semicircular pipe frame 11 and the soil-fixing mesh 12 can cooperate with each other to adjust the salinity and alkalinity of the plants near the roots. The soil is maintained and has the effect of consolidating the soil to prevent the soil near the root system from being loosened or dissolved due to the impact of water flow. By arranging the outer dropper 7 and the inner dropper 13, the outer dropper 7 transports salt water to the soil outside the three-way cultivation tube 10 and the semicircular tube rack 11, and the inner dropper 13 transports salt water to each end of the three-way cultivation tube 10 and the inside of the semicircular tube rack 11, so that the cultivation soil inside and outside can receive the salt water synchronously, wherein the root system of the plant will spread in the soil around each inner dropper 13, and the salinity of the soil around the root system of the plant will be directly changed by the inner dropper 13, so that the change of soil salinity has a more obvious effect on the growth of the plant.

[0039] like Figure 6As shown, the top of the inner dropper 13 is rotatably sleeved with two damping rings 16, and the same C-shaped telescopic rod 17 is fixedly installed on the side walls of the two damping rings 16 located at the same place. In this embodiment, both ends of the C-shaped telescopic rod 17 are telescopic ends, and a damping sliding connection is adopted to reduce the activity of the C-shaped telescopic rod 17; specifically, by setting the C-shaped telescopic rod 17, after the plant seeds or seedlings grow stems and leaves, the three C-shaped telescopic rods 17 around the plant stems and leaves can be rotated, and the distance between the C-shaped telescopic rod 17 and the plant stems can be changed forward and backward, so that the C-shaped telescopic rod 17 can support and protect the plant stems, reduce the impact of external environmental factors on the plant stems and leaves, and further affect the test work of the salt-alkali tolerance of the plant root system.

[0040] like Figure 6 As shown, a plurality of tie grooves 1701 are evenly provided on the C-shaped telescopic rod 17 from top to bottom. Figure 5 As shown, the same disposable tie 18 is inserted into three tie grooves 1701 located at the same height; specifically, by providing the disposable tie 18, as the stems and leaves of the plant grow further, they will be more affected by the flow of ambient air. At this time, the disposable tie 18 can be inserted into multiple tie grooves 1701 on the three C-shaped telescopic rods 17, so that the multiple disposable tie ties 18 can bundle the three C-shaped telescopic rods 17 around the periphery of the plant stems, thereby playing an anti-lodging role and further reducing the impact of environmental factors other than soil salinity.

[0041] like Figure 8 As shown, one end of the inner dropper 13 located inside the semicircular tube frame 11 is provided with two long sliding holes 1302 for cutting, and the two long sliding holes 1302 for cutting are evenly distributed along the axis of the inner dropper 13, as shown in FIG. Fig. 9 As shown, the same vertical cutting blade 19 is slidably installed inside the two long knife sliding holes 1302, and semi-ring cutting blades 20 are arranged on both sides of the inner dropper 13. The two semi-ring cutting blades 20 are respectively fixedly installed on both sides of the vertical cutting blade 19, and a control rod 21 is fixedly installed on the side wall of one of the semi-ring cutting blades 20. One end of the control rod 21 passes through the semi-circular tube frame 11 and extends to the outside of the semi-circular tube frame 11. Specifically, by arranging the vertical cutting blade 19, after the identification is completed, the three-way cultivation tube 10 and the semi-circular tube frame 11 can be connected. The circular tube rack 11 is dug out again, each group of semicircular tube racks 11 is opened, the soil is poured out, and then the plants are pulled out, and the inside of the three-way cultivation tube 10 and the semicircular tube rack 11 are cleaned. At this time, the control rod 21 can be pushed inward, so that the control rod 21 drives the vertical cutting blade 19 to slide horizontally along the long sliding hole 1302 on the inner dropper 13, and drives the semi-circular cutting blade 20 to move horizontally synchronously, so as to cut and crush the root system of the plant residue wrapped around the inner dropper 13, so as to quickly clean up the plant residue and facilitate the next round of plant identification.

[0042] like Figure 8 As shown, the control rod 21 is a three-section hinge rod structure, and a limiting hole 2101 is provided on the side wall of one end of the control rod 21 located outside the semicircular tube frame 11. Figure 7 As shown, a limit rotating shaft 22 is rotatably installed on the side wall of one of the semicircular tube racks 11, and one end of the limit rotating shaft 22 passes through the limit hole 2101 and is fixedly installed with a limit rotating plate 23. In this embodiment, the length of the limit hole 2101 is much larger than the length of the limit rotating plate 23; specifically, by setting the limit rotating plate 23, the structure of the multi-section hinge rod of the control rod 21 enables it to be folded. Before burying the three-way cultivation tube 10 and the semicircular tube rack 11, the control rod 21 can be pulled outward to the limit, and then the control rod 21 is bent to one side so that the end of the control rod 21 is attached to one side of one of the semicircular tube racks 11. At this time, the horizontal limit rotating plate 23 will pass through the limit hole 2101, and then the limit rotating plate 23 is rotated to make it vertical, so that the control rod 21 is clamped on one side of the semicircular tube rack 11, reducing the space occupied by the control rod 21.

[0043] like Figure 8 As shown, a soil-top inclined plate 24 is fixedly installed on the top of the semicircular tube rack 11, and the two soil-top inclined plates 24 located at the same place are symmetrically arranged with each other; specifically, by arranging the soil-top inclined plates 24, after the semicircular tube racks 11 on both sides are spliced ​​together, the two magnetic strips 15 will be attracted to each other, so that the two soil-top inclined plates 24 on the top are also spliced ​​together to form the shape of a triangular plate, so that when the three-way cultivation tube 10 and the semicircular tube rack 11 are dug out of the cultivation soil, the two soil-top inclined plates 24 located on the top of the joint of the semicircular tube rack 11 can easily break the top layer of soil, thereby facilitating the three-way cultivation tube 10 and the semicircular tube rack 11 to be pulled upward.

[0044] like Figure 2 As shown, a sewage trough 101 is provided on the top of the salt water platform 1, and a filtrate drain pipe 25 is fixedly installed on one side of the soil cultivation basin 2, one end of the filtrate drain pipe 25 faces the sewage trough 101, and a soil-fixing filter is provided inside the filtrate drain pipe 25; specifically, by providing the filtrate drain pipe 25, when the soil salinity in the soil cultivation basin 2 is reversely changed, the clean water input into the soil cultivation basin 2 will be mixed with the salt-alkali particles originally in the soil, and the excess mixture will be directly discharged from the filtrate drain pipe 25 into the sewage trough 101, thereby achieving the effect of washing salt and reducing the salinity of the soil in the soil cultivation basin 2. At the same time, the soil-fixing filter in the filtrate drain pipe 25 can prevent the soil from directly precipitating out, thereby playing a role in maintaining the soil.

[0045] like Figure 2As shown, a cleaning hose 26 is fixedly installed on one side of the salt water table 1, one end of the cleaning hose 26 extends to the interior of the salt water table 1 and is connected to the concentration regulating box, and a flushing nozzle 27 is fixedly installed on the top of the cleaning hose 26, and the flushing nozzle 27 is located on one side of the sewage tank 101. In this embodiment, a hook compatible with the flushing nozzle 27 is fixed on one side of the salt water table 1, so that the idle flushing nozzle 27 can be conveniently hung on the salt water table 1; specifically, by setting the flushing nozzle 27, after the plants inside the three-way cultivation tube 10 and the semicircular tube rack 11 are initially cleared, the three-way cultivation tube 10 and the semicircular tube rack 11 can be sent to the sewage tank 101 as a whole, and the flushing nozzle 27 is picked up to flush each three-way cultivation tube 10 and the semicircular tube rack 11, so that the residual soil and plant debris inside are removed, so as to reduce the impact of the residue on the next round of identification experiment of plant salt-alkali tolerance.

[0046] In summary: before identification: when using it for the first time, first put the culture soil in the soil cultivation pot 2, and dig a three-pronged tunnel in the culture soil, then open the semicircular tube racks 11 at each end of the three-way cultivation tube 10, and put the culture soil between the three-way cultivation tube 10 and the semicircular tube racks 11, and then plant the plant seeds or sprouts in the soil in the middle of the three-way cultivation tube 10, and then bury the three-way cultivation tube 10 in the three-pronged tunnel, and the support tube racks 6 on both sides of the soil cultivation pot 2 will support the external drip tube 7, so that the three-way cultivation tube 10 is suspended in the three-pronged tunnel, and at this time, continue to fill the soil in the soil cultivation pot 2 so that the culture soil covers the semicircular tube racks 11 at the bottom, and then repeat the above operation to complete the planting of plants and the placement of the three-way cultivation tube 10 in each soil cultivation pot 2;

[0047] During identification: salt water of different concentrations is extracted from the concentration regulating box by each infusion pump 3, and is sequentially input into different soil cultivation pots 2 through the telescopic hose 5, the connecting pipe 9, the annular pipe 8, the outer dropper 7 and the inner dropper 13; the outer dropper 7 transports salt water to the soil outside the three-way cultivation pipe 10 and the semicircular tube rack 11; the inner dropper 13 transports salt water to each end of the three-way cultivation pipe 10 and the inside of the semicircular tube rack 11, so that the cultivation soil inside and outside can receive the salt water synchronously; the root system of the plant will spread and grow in the three ports of the three-way cultivation pipe 10 and the three groups of semicircular tube racks 11, thereby observing the growth conditions of the plants in each soil cultivation pot 2 and testing the salt-alkali tolerance of the plants; when it is necessary to adjust the salinity of the cultivation soil midway, the infusion pump 3 can transport salt water of higher concentration into the soil of the soil cultivation pot 2 to increase the salinity of the cultivation soil, or directly transport clean water into the soil cultivation pot 2, and the clean water will mix with the salt-alkali particles originally in the soil, and the excess mixing will The filtrate is directly discharged from the filtrate drainage pipe 25 into the sewage tank 101 to achieve the effect of washing salt, and then the salinity is reversely reduced to quickly determine the specific salinity range corresponding to the salt-alkali tolerance of the plant of this category, wherein the root system of the plant will spread in the soil around each inner dropper 13, and the inner dropper 13 directly changes the salinity of the soil around the root system of the plant. After the plant seeds or seedlings grow stems and leaves, the three C-shaped telescopic rods 17 around the plant stems and leaves can be rotated, and the distance between the C-shaped telescopic rods 17 and the plant stems can be changed forward and backward, so that the C-shaped telescopic rods 17 can support and protect the plant stems, reduce the impact of external environmental factors on the plant stems and leaves, and after the plant stems and leaves grow further, they will be more affected by the flow of ambient air. At this time, disposable tie ties 18 can be sleeved in the multiple tie grooves 1701 on the three C-shaped telescopic rods 17, so that the multiple disposable tie ties 18 can tie the three C-shaped telescopic rods 17 around the plant stems to play an anti-lodging role;

[0048] After identification: After the identification is completed, the three-way cultivation tube 10 and the semicircular tube rack 11 are dug out again, each group of semicircular tube racks 11 are opened, the soil is poured out, and then the plants are pulled out. The inside of the three-way cultivation tube 10 and the semicircular tube rack 11 are cleaned. At this time, the control rod 21 can be pushed inward, so that the control rod 21 drives the vertical cutting blade 19 to slide horizontally along the long sliding hole 1302 on the inner dropper 13, and drives the semi-circular cutting blade 20 to move horizontally synchronously, so that the plant residues are entangled in the inner The roots around the dropper 13 are cut off and broken, so as to quickly clean up the plant residues. After the plants inside the three-way cultivation tube 10 and the semicircular tube rack 11 are initially cleared, the three-way cultivation tube 10 and the semicircular tube rack 11 can be sent to the sewage tank 101 as a whole, and the flushing nozzle 27 is used to flush each three-way cultivation tube 10 and the semicircular tube rack 11 to remove the residual soil and plant debris inside, so as to reduce the impact of the residues on the next round of identification experiments of plant salt-alkali tolerance.
