Description

Technical Field

[0001] The invention belongs to the technical field of agricultural experimental equipment, and in particular relates to equipment and a method for detecting salt-alkali resistance of rice used in agricultural experiments. Background Art

[0002] In agricultural production, rice is an important food crop, and its yield and quality are of great significance to food security and agricultural economic development. However, as a special type of land resource, saline-alkali land has the characteristics of high soil salt content and poor water conditions, which seriously restricts the growth of crops such as rice. Therefore, screening and cultivating salt-alkali tolerant rice varieties and improving the yield and quality of rice in saline-alkali land have become important directions of current agricultural research. In order to achieve this goal, agricultural researchers are in urgent need of a detection device that can accurately and efficiently evaluate the salt-alkali tolerance of rice.

[0003] The Chinese patent with the existing announcement number CN218736424U discloses a rice salt tolerance identification device that is easy to regulate, including a bracket. This device realizes the mutual circulation between the internal culture solutions by opening a connecting hole inside the culture tank, thereby providing convenience for subsequent concentration control. The salinity detector installed on one side of the culture tank is used to detect the salinity inside the culture tank in real time, and input it into the calculation control unit through the data transmission line. The calculation control unit is used to display the reading of the salinity detector in real time, thereby reflecting the salt water concentration inside the culture tank. Once the salt concentration of the water inside the culture tank needs to be changed, as long as the water pump is controlled by the calculation control unit to input the salt water inside the salt water barrel into the inside of the culture tank, so that the salt concentration inside the culture tank is increased to the required index, the negative feedback of the data can be realized by the salinity detector and the calculation control unit until the salinity inside the culture tank reaches the predetermined requirement, thereby realizing the effect of automatic control of salinity.

[0004] However, the above technical solutions still have the following deficiencies:

[0005] The water pump can only transport brine to a fixed culture tank, and then the brine in the culture tank gradually diffuses to the other culture tanks. However, due to the different positions of the multiple culture tanks, the brine diffusion effect is also different, resulting in different concentrations of brine in the multiple culture tanks, resulting in poor accuracy of the experimental data, which needs to be improved.

DETAILED DESCRIPTION

[0035] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] Example 1: Figure 1-Figure 3 , Figure 7 and Figure 8 As shown, the salt-alkali tolerance detection equipment for rice used in agricultural experiments includes a storage basket 100, a plurality of culture boxes 111, a box body 200, a stirring mechanism 210, a mounting frame 300, two plant growth lamps 301, a pumping mechanism 310, a driving mechanism 320 and a cleaning mechanism 330.

[0037] The top of the storage basket 100 is open, and multiple cuttings 101 are installed in the storage basket 100. The top of the culture box 111 is open, and a socket 112 is installed on the side of the culture box 111. The culture box 111 is plugged with the cuttings 101 on the storage basket 100 through the socket 112. A salinity detector 113 is installed inside the culture box 111; the multiple culture boxes 111 in the storage basket 100 are divided into two rows.

[0038] The box body 200 is fixedly connected to the storage basket 100, and a hopper 201 is installed on the top surface of the box body 200. The stirring mechanism 210 is used to stir the sodium chloride, sodium bicarbonate and water in the box body 200; the mounting frame 300 is fixedly connected to the box body 200, and two supporting columns are installed between the mounting frame 300 and the storage basket 100; two plant growth lamps 301 are installed on the inner bottom surface of the mounting frame 300; the pumping mechanism 310 is used to transport the saline water prepared in the box body 200 to the culture box 111, and the pumping mechanism 310 includes a hollow box 313; the driving mechanism 320 is used for horizontal movement of the hollow box 313; the cleaning mechanism 330 is used to clean the plant growth lamp 301.

[0039] Specifically, the experimental rice is planted in a plurality of culture boxes 111. Then, a certain proportion of sodium chloride, sodium bicarbonate and water are added into the box 200 through the feeding hopper 201, and then the stirring mechanism 210 is started to stir the sodium chloride, sodium bicarbonate and water in the box 200, so as to produce saline water that meets the requirements.

[0040] Then, by starting the pumping mechanism 310, the saline water in the box 200 is transported to the culture box 111 until the salinity in the culture box 111 meets the requirements; then, by starting the driving mechanism 320, the hollow box 313 is driven to move, and then the hollow box 313 is moved to the top of the other culture boxes 111, and then the saline water is transported to the other culture boxes 111 through the hollow box 313.

[0041] When the rice is growing, the plant growth lamp 301 is started to irradiate the rice in the culture box 111 to stimulate the growth of the rice. When the driving mechanism 320 drives the hollow box 313 to move, it also drives the cleaning mechanism 330 to move. The moving cleaning mechanism 330 cleans the bottom surface of the plant growth lamp 301, thereby removing the dust attached to the plant growth lamp 301 and ensuring the normal use of the plant growth lamp 301.

[0042] like Figure 7 and Fig. 9 As shown, the pumping mechanism 310 also includes a pump body 311 and two liquid discharge pipes 314. The pump body 311 is installed on the top surface of the box body 200, the other end of the liquid pumping pipe of the pump body 311 extends into the box body 200, and the other end of the delivery pipe 312 of the pump body 311 is fixedly connected to the hollow box 313; the delivery pipe 312 is a hose. The two liquid discharge pipes 314 are both installed on the bottom surface of the hollow box 313.

[0043] Specifically, when the pump body 311 is running, the saline water in the box body 200 will be pumped out through the suction pipe, and then the saline water will be transported to the hollow box 313 through the delivery pipe 312. The saline water in the hollow box 313 will be discharged into the culture box 111 through the discharge pipe 314.

[0044] like Figure 7 and Figure 8 As shown, the rice salt-alkali tolerance detection equipment for agricultural experiments also includes a plurality of first racks 302, a plurality of second racks 303 and a fixing bar 304. The plurality of first racks 302 are all mounted on the bottom surface of the mounting frame 300, and the plurality of first racks 302 are all located between two plant growth lamps 301; the plurality of second racks 303 are all mounted on the bottom surface of the mounting frame 300, and the plurality of second racks 303 are all located between two plant growth lamps 301, and the plurality of second racks 303 are staggered with the plurality of first racks 302. The fixing bar 304 is mounted on the mounting frame 300, and the fixing bar 304 is slidably connected to the hollow box 313.

[0045] like Figure 7-Figure 9 As shown, the driving mechanism 320 includes a second motor 321, a lead screw 322, a lead screw nut 323, a fixing plate 324, a vertical column 325 and a first gear 326. The second motor 321 is mounted on the mounting frame 300; the lead screw 322 is fixedly connected to the power output shaft of the second motor 321; the lead screw nut 323 is sleeved on the lead screw 322; the fixing plate 324 is fixedly sleeved on the lead screw nut 323, and the fixing plate 324 is fixedly connected to the top surface of the hollow box 313. The vertical column 325 is rotatably connected to the top surface of the fixing plate 324; the first gear 326 is fixedly connected to the top of the vertical column 325, and the first gear 326 is meshed with the first rack 302 and the second rack 303.

[0046] Specifically, when the second motor 321 is running, it will drive the lead screw 322 to rotate, thereby moving the lead screw nut 323, and then driving the vertical column 325 and the hollow box 313 to move, and then driving the drainage pipe 314 to move, so that the hollow pipe can transport saline water to other culture boxes 111.

[0047] When the fixed plate 324 moves, the vertical column 325 and the first gear 326 will be driven to move. When the first gear 326 moves horizontally, the first gear 326 will be alternately meshed with the first rack 302 and the second rack 303. When the horizontally moving first gear 326 is meshed with the first rack 302 or the second rack 303, the first gear 326 will rotate. As the first gear 326 continues to move horizontally, the first gear 326 will rotate back and forth clockwise and counterclockwise.

[0048] like Figure 8 and Fig. 9As shown, the cleaning mechanism 330 includes two cleaning brushes 331, two mounting rods 332 and a plurality of vertical pins 333. The two cleaning brushes 331 are both mounted on the vertical column 325, and the two cleaning brushes 331 are used to clean the bottom surfaces of the two plant growth lamps 301; the two mounting rods 332 are both mounted on the hollow box 313, and the upper part of the mounting rods 332 is arranged in a "C" shape. A plurality of vertical pins 333 are respectively mounted on the two mounting rods 332, and the cleaning brushes 331 can pass through the plurality of vertical pins 333.

[0049] Specifically, when the hollow box 313 moves, the cleaning brush 331 will also move, and the moving cleaning brush 331 will clean the bottom surface of the plant growth lamp 301, thereby ensuring the normal use of the plant growth lamp 301.

[0050] And when the hollow box 313 moves, it will drive the fixed plate 324, the vertical column 325 and the first gear 326 to move horizontally. Under the action of the first rack 302 and the second rack 303, the first gear 326 and the vertical column 325 will rotate back and forth clockwise and counterclockwise, thereby driving the two cleaning brushes 331 to rotate back and forth clockwise and counterclockwise. When the cleaning brush 331 rotates, the cleaning brush 331 will pass through the multiple vertical needles 333. With the intermittent contact between the cleaning brush 331 and the multiple vertical needles 333, the dust collected inside the cleaning brush 331 will be cleaned away, thereby ensuring the cleaning effect of the cleaning brush 331 on the plant growth lamp 301.

[0051] Working principle: In specific use, the experimental rice is planted in multiple culture boxes 111, and then a certain proportion of sodium chloride, sodium bicarbonate and water are added into the box 200 through the feeding hopper 201. Then, the stirring mechanism 210 is started to stir the sodium chloride, sodium bicarbonate and water in the box 200, so as to produce saline water that meets the requirements.

[0052] Then, by starting the pump body 311, the pump body 311 will extract the saline water in the box body 200 through the suction pipe, and then transport the saline water to the hollow box 313 through the delivery pipe 312. The saline water in the hollow box 313 will be discharged into the culture box 111 through the discharge pipe 314 until the salinity in the culture box 111 meets the requirements.

[0053] Then, by starting the second motor 321 , it drives the lead screw 322 to rotate, thereby moving the lead screw nut 323 , thereby driving the vertical column 325 and the hollow box 313 to move, and then driving the drainage pipe 314 to move, so that the hollow pipe can transport saline water to other culture boxes 111 .

[0054] When the rice is growing, the plant growth lamp 301 is started to irradiate the rice in the culture box 111 to stimulate the growth of the rice. When the second motor 321 is running, it will move through the lead screw 322, the lead screw nut 323, the fixing plate 324 and the hollow box 313. When the fixing plate 324 moves, it will drive the vertical column 325 and the first gear 326 to move. When the first gear 326 moves horizontally, the first gear 326 will alternately mesh with the first rack 302 and the second rack 303. When the horizontally moving first gear 326 meshes with the first rack 302 or the second rack 303, the first gear 326 will rotate; The first gear 326 continues to move horizontally, and the first gear 326 will rotate back and forth clockwise and counterclockwise, thereby driving the two cleaning brushes 331 to rotate back and forth clockwise and counterclockwise. When the cleaning brush 331 rotates, the cleaning brush 331 will pass through the multiple vertical needles 333. As the cleaning brush 331 intermittently contacts the multiple vertical needles 333, the dust collected inside the cleaning brush 331 will be cleaned away, thereby ensuring the cleaning effect of the cleaning brush 331 on the plant growth lamp 301.

[0055] Example 2: Figure 1 and Figure 4-Figure 6 As shown, when other parts are the same as those in the embodiment, the difference between this embodiment and the embodiment is that:

[0056] The stirring mechanism 210 includes two shafts 211, a plurality of stirring rods 212, two first square plugs 213, two rotating shafts 214, two second square plugs 215, four transmission members 217, four connecting members 216, a first motor 218 and a driving gear 219. The two shafts 211 both penetrate one side of the box body 200 and are rotatably connected to the box body 200; the plurality of stirring rods 212 are respectively mounted on the parts of the two shafts 211 located inside the box body 200; the two first square plugs 213 are respectively fixedly connected to one end of the two shafts 211 located outside the box body 200; the two rotating shafts 214 are both rotatably connected to the side of the box body 200; and the two second square plugs 215 are respectively fixedly connected to the two rotating shafts 214.

[0057] The four transmission members 217 are respectively plugged with the two first square plug rods 213 and the two second square plug rods 215; the transmission member 217 includes a mounting tube 2171 and a driven gear 2172. The mounting tube 2171 is plugged with the first square plug rod 213 and the second square plug rod 215; the driven gear 2172 is fixedly sleeved on the mounting tube 2171, and the driven gear 2172 at the bottom is meshed and connected with the driving gear 219.

[0058] The four connecting members 216 are detachably connected to the two first square inserting rods 213 and the two second square inserting rods 215 , respectively, and the connecting members 216 are bolts and nuts.

[0059] The first motor 218 is installed on the side of the storage basket 100 ; the driving gear 219 is fixedly connected to the power output shaft of the first motor 218 .

[0060] Specifically, when the first motor 218 is running, the first motor 218 will drive the driving gear 219 to rotate, and then drive the driven gear 2172 located at the bottom to rotate, and because the four driven gears 2172 are meshed with each other, when the driven gear 2172 located at the bottom rotates, it will drive the other three driven gears 2172 to rotate synchronously; when the four driven gears 2172 rotate, they will drive the two first square plugs 213 and the two second square plugs 215 to rotate, and then drive the two shafts 211 and the two rotating shafts 214 to rotate, and when the two shafts 211 rotate, they will drive multiple stirring rods 212 to rotate.

[0061] Working principle: When it is necessary to prepare saline water, a certain proportion of sodium chloride, sodium bicarbonate and water are added into the box 200 through the feeding hopper 201.

[0062] Then, by starting the first motor 218, the power output shaft of the first motor 218 drives the driving gear 219 to rotate, and then meshes and drives the driven gear 2172 at the bottom to rotate. Since the four driven gears 2172 mesh with each other, when the driven gear 2172 at the bottom rotates, it will drive the other three driven gears 2172 to rotate synchronously.

[0063] When the four driven gears 2172 rotate, the two first square plug rods 213 and the two second square plug rods 215 will be driven to rotate, and then the two shafts 211 and the two rotating shafts 214 will be driven to rotate. When the two shafts 211 rotate, the multiple stirring rods 212 will be driven to rotate, and then the sodium chloride, sodium bicarbonate and water in the box 200 will be stirred to obtain saline water.

[0064] Example 3: Fig.10 and Fig.11 As shown, when other parts are the same as those in the embodiment, the difference between this embodiment and the embodiment is that:

[0065] The transmission member 217 further includes a circular plate 2173 , which is fixedly sleeved on the mounting tube 2171 .

[0066] The rice salt-alkali tolerance testing equipment for agricultural experiments also includes four rotating columns 102 and four third-party shaped plug rods 103. The four rotating columns 102 are rotatably connected to the storage basket 100 and the box body 200 respectively; the four third-party shaped plug rods 103 are fixedly connected to the four rotating columns 102 respectively, and the third-party shaped plug rods 103 are provided with holes matching the connecting piece 216, and the third-party shaped plug rods 103 are plugged and matched with the installation tube 2171.

[0067] Working principle: During specific use, when the device needs to be moved, the four connecting members 216 are removed from the two first square plug rods 213 and the two second square plug rods 215 respectively, so that the four transmission members 217 can be moved on the first square plug rod 213 and the second square plug rod 215, and then the four transmission members 217 are removed from the first square plug rod 213 and the second square plug rod 215.

[0068] Then, the mounting cylinders 2171 on the four transmission members 217 are respectively plugged into the four third-party plug rods 103 . It should be noted that when the mounting cylinders 2171 on the transmission member 217 are plugged into the third-party plug rods 103 , the driven gear 2172 of the transmission member 217 is located between the rotating column 102 and the circular plate 2173 .

[0069] Finally, the four connecting members 216 are connected to the four third-party shaped inserting rods 103 respectively, so that the transmission member 217 cannot be separated from the third-party shaped inserting rod 103 by itself.

[0070] At this time, the bottom surfaces of the storage basket 100 and the box body 200 are separated from the ground, and the four circular plates 2173 are in contact with the ground, so that the four circular plates 2173 act as temporary moving wheels, thereby making the device easier to push and improving the flexibility of the device.

[0071] Example 4: Figure 1-Figure 9 As shown, the method for detecting the salt-alkali tolerance of rice in agricultural experiments includes the following steps:

[0072] Step 1: Rice planting: Place the rice salt-alkali tolerance testing equipment for agricultural experiments in the laboratory to ensure that the equipment is stable and all components are connected properly; plant experimental rice in multiple planting boxes 111 to ensure that the planting density of rice is consistent;

[0073] Step 2, preparing saline water: adding a certain proportion of sodium chloride, sodium bicarbonate and water into the box 200, and then starting the stirring mechanism 210 to fully stir the sodium chloride, sodium bicarbonate and water in the box 200 to obtain saline water that meets the requirements;

[0074] Step 3: Transporting saline-alkali water: Start the pumping mechanism 310 of the equipment, transport the prepared saline-alkali water in the box 200 to the hollow box 313 through the delivery pipe 312, and then transport the saline-alkali water to the planting box 111 until the salinity in the culture box 111 meets the requirements; control the driving mechanism 320 to drive the hollow box 313 to move horizontally, so that the hollow box 313 moves to the top of the remaining planting boxes 111, and then transport the saline-alkali water to the planting box 111 below through the hollow box 313, and then repeat this step until the salinity in all the culture boxes 111 meets the requirements;

[0075] Step 4: Stimulate rice growth: Start the plant growth lamp 301 to irradiate the rice in the planting box 111 to stimulate rice growth;

[0076] Step 5: Maintenance of the plant growth lamp 301: When the driving mechanism 320 drives the hollow box 313 to move, the cleaning mechanism 330 will also move accordingly. At this time, the cleaning brush 331 on the cleaning mechanism 330 will clean the bottom surface of the plant growth lamp 301; and the cleaning brush 331 will rotate clockwise and counterclockwise alternately during the movement, and at the same time, the cleaning brush 331 will pass through the plurality of vertical pins 333, and clean the dust collected inside the cleaning brush 331 through the vertical pins 333;

[0077] Step 6. Experimental data recording and analysis: Regularly record the growth of rice and changes in salinity, analyze and process the recorded experimental data, and evaluate the salt-alkali tolerance of rice and the experimental results.
