Description

Technical Field

[0001] The invention relates to the technical field of cotton seed vitality determination, in particular to a planting test device for cotton seed vitality determination and a cotton seed vitality determination method. Background Art

[0002] Cotton seed vigor is an important indicator for measuring seed quality. It is directly related to the emergence rate after sowing, the growth potential of seedlings, and the yield and quality of the final crop. The vitality of cotton seeds is reflected by the vitality value of cotton seeds (i.e., the sum of the germination rate of cotton seeds at a low temperature of 18°C ​​and the germination rate at an appropriate temperature of 30°C). For cotton seeds, seeds with high vitality can ensure rapid and uniform emergence in the field, thus laying a good foundation for full seedlings. Determining the vitality of cotton seeds not only helps to increase the field density of crops, but also creates favorable conditions for increasing production. In addition, seeds with high vitality have strong vitality and strong resistance to field adversities (such as drought, saline-alkali and other adverse environments), thereby improving the overall disease resistance of cotton crops. The determination of cotton seed vitality can also help optimize sowing strategies. For example, some cotton varieties have a short growing season and require early sowing to ensure a certain yield. High-vigor seeds are resistant to low temperatures in early spring, so they can be sown earlier, which is not only conducive to increasing yields, but also saving sowing costs. In summary, the purpose and significance of measuring cotton seed vitality is to provide high-quality seed resources for agricultural production by evaluating the physiological activity and health status of seeds, thereby ensuring high yield, quality and stable yield of cotton crops.

[0003] In the prior art, the specific process of the cotton seed vitality test is as follows: separate the clean seeds from the cotton seed sample to be tested, and randomly select 100 seeds from the mixed clean seeds as a repeat. Take an appropriate amount of wet sand from the germination box and put it into the bottom of the germination box to flatten it, then place the sample to be tested on the flat wet sand in the germination box (test pot), use a flat-bottomed container to flatten the seeds, and then spread a layer of 1 cm thick wet sand on the cotton seed sample to be tested, and spread it evenly and cover the germination box lid. Finally, the sample to be tested (cotton seeds) is placed in a light culture test box at 18℃±1℃ to determine the germination rate of the cotton seeds (low temperature germination method) and the cotton seeds are placed in a light culture test box at 30℃±1℃ to determine the germination rate of the cotton seeds (suitable temperature germination method). According to the cotton seed germination rate measured by the low temperature germination method for the sample to be tested and the cotton seed germination rate measured by the suitable temperature germination method for the sample to be tested, the calculation formula for the cotton seed vitality value is: V=G S + G C In the above formula, V represents the cotton seed vitality value, G S Indicates the germination rate of cotton seeds in the optimum temperature germination method, GC It represents the germination rate of cotton seeds by the low-temperature germination method. From the specific process of the above-mentioned cotton seed vitality determination test, it can be known that the key equipment that affects the reliability of the entire cotton seed germination test is the light cultivation test box. However, the main technical problems of the light cultivation test box in the prior art are: 1. The temperature heating is uneven, and the temperature detection is not accurate enough, and the temperature in the light cultivation test box cannot be accurately controlled in real time. 2. In the germination test of cotton seeds, the number of samples to be tested in a group is 100, and a large number of test pots are required. The laying and placement of the test pots in the sand bed of the currently used light cultivation test box are very inconvenient, and the operator needs to lean over and explore the light cultivation test box.

[0018] The method for determining the vitality of cotton seeds using the planting test device for determining the vitality of cotton seeds is as follows: Step 1: Treatment of sand for sand bed: select sand with a diameter of 0.05 mm to 0.80 mm and a pH value of 6.0 to 7.5, and dry the sand at a high temperature of 130°C to 170°C for 2 hours for disinfection; add 15 ml of water to each 100 g of dry sand and stir evenly; Step 2, laying of sand on the sand bed: 1, the control key of the hydraulic telescopic mechanism 107, the PLC control module sends an opening control instruction to the solenoid valve of the hydraulic telescopic mechanism hydraulic cylinder, the telescopic rod of the hydraulic cylinder extends, and the telescopic rods of the hydraulic cylinders on the left and right sides push the fixed seat 2 to move upward, thereby pushing the box cover 1 and the box cover 2 to open, and open the box cover 1 and the box cover 2; then the operator clicks on the lifting module of the lifting hydraulic cylinder of the hydraulic lifting mechanism on the display screen, at this time, the PLC control module of the human-computer interaction system sends an opening control instruction to the solenoid valve of the hydraulic station, and the hydraulic station delivers high-pressure oil to the lifting hydraulic cylinder, at this time, the telescopic rod of the lifting hydraulic cylinder extends, pushing the connector, the support plate and the sliding block to move upward along the column, and in the process of the support plate moving upward, the sand bed frame and the sand bed are driven to move upward, and when the lifting hydraulic cylinder is lifted to the maximum stroke, the sand bed frame and the sand bed are lifted to a position close to the upper edge of the box body; finally, the operator pours the sand after adding water and stirring on the sand bed and spreads it flat; Step 3: Extrusion molding of the planting pot concave: When the sand on the sand bed is flattened, the operator clicks the control key to start the concave pressing device on the display screen. At this time, the PLC control module sends a start control command to the solenoid valve on the hydraulic station that supplies hydraulic oil to the left and right linear telescopic mechanisms. The hydraulic station supplies hydraulic oil to the hydraulic telescopic cylinder of the linear telescopic mechanism through the solenoid valve. At this time, the telescopic rods of the hydraulic telescopic cylinders on the left and right linear telescopic mechanisms retract synchronously. The retraction action of the telescopic rods of the hydraulic telescopic cylinders drives the sliding body to move backward through the connecting rod. The backward movement of the sliding body and the connecting rod drives the square block 1 and the square block 2 to move backward. The gear wheel is rotated by the gear wheel to move backward, and the driven gear wheel rotates counterclockwise, and the driven gear wheel rotates counterclockwise, and the rotating shaft and the denting plate are driven to turn backward with the shaft seat as the center under the action of the driven gear wheel rotating counterclockwise. When the denting plate turns over to the sand grains of the sand bed body, the gravity of the denting plate and the denting cone is utilized, and the denting cone and the sand grains of the sand bed body are squeezed to form a concave cavity for placing the planting pot. After the concave cavity is formed, the operator clicks the control key of the denting device on the display screen to raise the denting device, and the denting plate of the denting device rises and leaves the sand bed, and is in a vertical state. Step 4, placement of test seeds in planting pots: select 100 clean cotton seeds with full grains for standby use; select an appropriate amount of the wet sand treated in step 1 and put them into the planting pot to spread it flat, with a thickness of 1cm to 2cm, then place a clean cotton seed with full grains on the flat sand, and finally cover it with a layer of 1cm wet sand and spread it evenly; there are a total of 100 planting pots, and the above 100 planting pots are placed in the frustum-shaped recesses respectively; at the same time, the operator clicks the control key for the hydraulic lifting mechanism to descend on the display screen, and the hydraulic lifting mechanism moves the sand bed frame and the sand bed planting box to the bottom position; finally, the operator clicks the control key for the hydraulic telescopic mechanism of the planting box on the display screen, and the PLC control module sends an opening control command to the solenoid valve that supplies oil to the hydraulic cylinder of the hydraulic telescopic mechanism, and the telescopic rod of the hydraulic cylinder retracts, and the telescopic rods of the hydraulic cylinders on the left and right sides simultaneously pull the box cover 1 and the box cover 2 to cover the box body of the planting box; Step 5. Optimal temperature germination test for cotton seeds: First, the operator clicks on the optimal temperature germination test mode on the display screen, and uses thermocouple 1, thermocouple 2, and thermocouple 3 to monitor the temperature of the planting box in real time. When the temperature of the box reaches the preset constant temperature threshold of 30°C, the PLC control module sends a control command to reduce the opening to the solenoid valve of the electromagnetic heating device, and the oil pump inputs less high-temperature oil to the oil inlet end of the heat dissipation coil, thereby reducing the heat exchange of the heat dissipation coil and lowering the temperature in the box; when the temperature of the box is lower than the preset constant temperature threshold of 30°C, the PLC control module sends a control command to increase the opening to the solenoid valve of the electromagnetic heating device, and the oil pump inputs more high-temperature oil to the oil inlet end of the heat dissipation coil, thereby increasing the heat exchange of the heat dissipation coil and increasing the temperature in the box. , through the cooperation of the PLC control module, thermocouple 1, thermocouple 2, thermocouple 3 and the solenoid valve, the temperature in the box is always kept at a constant temperature of 30°C; under the condition that the box of the planting box is kept at a constant temperature of 30°C, the operator clicks the light on button on the display screen every day, and the PLC control module pre-sets the lighting time for 8 hours. At this time, the PLC control module sends an on control instruction to the control switch of the fluorescent lamp. After the fluorescent lamp is turned on for continuous lighting for 8 hours, the PLC control module sends a off control instruction to the control switch of the fluorescent lamp, and the fluorescent lamp is turned off; the germination rate test of the suitable temperature germination test of cotton seeds is repeated four times, and the first counting time of the suitable temperature germination test of cotton seeds is the fourth day after the test seeds are placed in the planting pot, and the last counting time is the twelfth day after the test seeds are placed in the planting pot; Step 6: Low-temperature germination test of cotton seeds: First, the operator clicks on the low-temperature germination test mode on the display screen, and uses thermocouple 1, thermocouple 2, and thermocouple 3 to monitor the temperature of the planting box in real time. When the temperature of the box reaches the preset constant temperature threshold of 18°C, the PLC control module sends a control command to reduce the opening to the solenoid valve of the electromagnetic heating device, and the oil pump inputs less high-temperature oil to the oil inlet end of the heat dissipation coil, thereby reducing the heat exchange of the heat dissipation coil and lowering the temperature in the box; when the temperature of the box is lower than the preset constant temperature threshold of 18°C, the PLC control module sends a control command to increase the opening to the solenoid valve of the electromagnetic heating device, and the oil pump inputs more high-temperature oil to the oil inlet end of the heat dissipation coil, thereby increasing the heat exchange of the heat dissipation coil and increasing the temperature in the box. , through the cooperation of the PLC control module, thermocouple 1, thermocouple 2, thermocouple 3 and the solenoid valve, the temperature in the box is always kept at a constant temperature of 18°C; under the condition that the box of the planting box is kept at a constant temperature of 18°C, the operator clicks the light on button on the display screen every day, and the PLC control module pre-sets the lighting time for 8 hours. At this time, the PLC control module sends an on control instruction to the control switch of the fluorescent lamp. After the fluorescent lamp is turned on for continuous lighting for 8 hours, the PLC control module sends a off control instruction to the control switch of the fluorescent lamp, and the fluorescent lamp is turned off; the germination rate test of the low-temperature germination test of cotton seeds is repeated four times, and the initial counting time of the low-temperature germination test of cotton seeds is the 11th day after the test seeds are placed in the planting pot, and the last counting time is the 18th day after the test seeds are placed in the planting pot; Step 7. Calculation of normal seedling statistics and germination rate: According to the identification standard of cotton seed germination test seedlings, the normal seedling values ​​of cotton seed germination tests repeated four times under the suitable temperature germination test mode are counted; at the same time, the normal seedling values ​​of cotton seed germination tests repeated four times under the low temperature germination test mode are counted; the normal seedling values ​​of one to four times under the above-mentioned suitable temperature germination test mode and low temperature germination test mode are respectively input into the human-computer interaction system through the parameter input mode of the display screen, and the operation module calculates the germination rate of cotton seeds according to the formula , calculate the cotton seed germination rate of four repeated tests under the suitable temperature germination test mode and the low temperature germination test mode; In the above formula, G represents the germination rate, which is expressed in percentage; It represents the number of normal seedlings (i=1~4) of the corresponding replicate, in units of plants; Step 8. Calculation of cotton seed vitality value: The calculation module substitutes the cotton seed germination rate of four repeated tests under the above-mentioned suitable temperature germination test mode and low temperature germination test mode into the cotton seed vitality value calculation formula V=G s +G cThe cotton seed vitality value is calculated in the process; when the cotton seed vitality value is greater than or equal to 160, it is the first level super high; when the cotton seed vitality value is between 140 and 159, it is the second level high; when the cotton seed vitality value is between 120 and 139, it is the third level medium; when the cotton seed vitality value is less than or equal to 119, it is the fourth level low; In the above formula for calculating the vigor value of cotton seeds, V represents the value of the vigor value of cotton seeds, in percentage; G s Indicates the value of germination rate under the optimum temperature germination test mode, in percentage; G c It indicates the value of germination rate in low temperature germination test mode.

The sand bed frame 10 includes a sand bed frame body 1001. The sand bed frame body 1001 is square in shape. The sand bed placement groove 1002 is opened at the center position of the sand bed frame body 1001. The bottom of the sand bed placement groove 1002 is provided with convex edges 1003 around it.

[0035] By providing the sand bed placement groove 1002 and the convex edge 1003 at the center position of the sand bed frame body 1001, the sand bed 11 can be placed in the sand bed placement groove 1002 and the convex edge 1003.

[0039] The above-mentioned arrangement of the linear telescopic mechanism 131 utilizes the synchronous retraction or extension action of the telescopic rods of the hydraulic telescopic cylinders 1318 on the left and right linear telescopic mechanisms 131. The retraction or extension action of the telescopic rods of the hydraulic telescopic cylinders 1318 drives the sliding body 1313 to move backward or forward through the connecting rod 13120. The backward or forward movement of the sliding body 1313 and the connecting rod 13120 drives the square block 1 1315 and the square block 2 1312 to move backward or forward, thereby driving the bar rack 133 on the fixed block 132 to move backward or forward; on the one hand, it provides telescopic power for the backward or forward movement of the bar rack 133; on the other hand, it provides a linear driving force for the rotation of the driven gear 134 (through the meshing transmission of the bar rack 133 with the driven gear 134).

[0043] like Figure 1-10 As shown, a specific embodiment of the method for measuring the vitality of cotton seeds using the planting test device for measuring the vitality of cotton seeds is as follows: Example

[0044] Step 1: Treatment of sand for sand bed: select sand with a diameter of 0.05 mm to 0.80 mm and a pH value of 6.0 to 7.5, and dry the sand at a high temperature of 130°C to 170°C for 2 hours for disinfection; add 15 ml of water to each 100 g of dry sand and stir evenly; Step 2. Laying of sand on the sand bed: First, the operator clicks the control key of the hydraulic telescopic mechanism 107 of the planting box 1 on the display screen 42, and the PLC control module 43 sends an opening control command to the solenoid valve that supplies oil to the hydraulic cylinder 1071 of the hydraulic telescopic mechanism 107, and the telescopic rod of the hydraulic cylinder 1071 extends. The telescopic rods of the hydraulic cylinder 1071 on the left and right sides push the fixed seat 2 1073 to move upward, thereby pushing the box cover 1 105 and the box cover 2 106 to open, and open the box cover 1 105 and the box cover 2 106; then the operator clicks the lifting module of the lifting hydraulic cylinder 96 of the hydraulic lifting mechanism 9 on the display screen 42 At this time, the PLC control module 43 of the human-machine interaction system 4 sends an opening control command to the solenoid valve of the hydraulic station 2, and the hydraulic station 2 delivers high-pressure oil to the lifting hydraulic cylinder 96. At this time, the telescopic rod of the lifting hydraulic cylinder 96 extends, pushing the connector 94, the support plate 95 and the sliding block 93 to move upward along the column 91. In the process of the support plate 95 moving upward, the sand bed frame 10 and the sand bed 11 are driven to move upward. When the lifting hydraulic cylinder 96 is lifted to the maximum stroke, the sand bed frame 10 and the sand bed 11 are lifted to a position close to the upper edge of the box 101; finally, the operator pours the sand after adding water and stirring on the sand bed 11 and spreads it flat; Step 3: Extrusion molding of the planting pot concave: After the sand on the sand bed 11 is flattened, the operator clicks the control key on the display screen 42 to start the concave pressing device 13. At this time, the PLC control module 43 sends a start control command to the solenoid valve on the hydraulic station 2 that supplies hydraulic oil to the left and right linear telescopic mechanisms 131. The hydraulic station 2 supplies hydraulic oil to the hydraulic telescopic cylinder 1318 of the linear telescopic mechanism 131 through the solenoid valve. At this time, the telescopic rods of the hydraulic telescopic cylinder 1318 on the left and right linear telescopic mechanisms 131 retract synchronously. The retraction action of the telescopic rod of the hydraulic telescopic cylinder 1318 drives the sliding body 1313 to move backward through the connecting rod 13120. The backward movement of the sliding body 1313 and the connecting rod 13120 drives the square block 1 1315 and the square block 2 1312 to move backward, and at the same time drives The bar-shaped rack 133 on the fixed block 132 moves to the rear side, and at this time, the driven gear 134 rotates counterclockwise through the meshing action of the bar-shaped rack 133 and the driven gear 134. Under the counterclockwise rotation of the driven gear 134, the rotating shaft 136 and the denting plate 137 are driven to flip to the rear side with the shaft seat 135 as the center. When the denting plate 137 flips over to the sand grains 112 of the sand bed body 111, the denting plate 137 and the denting cone 139 have their own gravity, and the denting cone 139 and the sand grains 112 of the sand bed body 111 are squeezed to form a recess 113 for placing the planting pot 12; after the recess 113 is formed, the operator clicks the control key for raising the denting device 13 on the display screen 42, and the denting plate 137 of the denting device 13 rises and leaves the sand bed 11, and is in a vertical state; Step 4, placement of test seeds in the planting pot: select 100 cotton seeds with full grains for standby; select an appropriate amount of the wet sand 112 processed in step 1 and put it into the planting pot 12 and spread it flat, the thickness of the sand 112 is 1cm to 2cm, then place a cotton seed with full grains on the flat sand 112, and finally cover it with a layer of 1cm thick wet sand 112, and spread it evenly; there are a total of 100 planting pots 12, and the above 100 planting pots 12 are placed in the cone-shaped recesses 113 respectively; at the same time, the operator clicks on the display screen 42 to The control key for lowering the lifting mechanism 9 is pressed, and the hydraulic lifting mechanism 9 moves the sand bed frame 10 and the sand bed 11 to the bottom of the box body 101 of the planting box 1; finally, the operator clicks the control key of the hydraulic telescopic mechanism 107 of the planting box 1 on the display screen 42, and the PLC control module 43 sends an opening control command to the solenoid valve supplying oil to the hydraulic cylinder 1071 of the hydraulic telescopic mechanism 107, and the telescopic rod of the hydraulic cylinder 1071 retracts, and the telescopic rods of the hydraulic cylinders 1071 on the left and right sides simultaneously pull the box cover 105 and the box cover 2 106 to cover the box body 101 of the planting box 1; Step 5, suitable temperature germination test of cotton seeds: First, the operator clicks on the suitable temperature germination test mode on the display screen 42, and uses the thermocouple 1 6, the thermocouple 2 7, and the thermocouple 3 8 to monitor the temperature of the box 101 of the planting box 1 in real time. When the temperature of the box 101 reaches the preset constant temperature threshold of 30°C, the PLC control module 43 sends a control instruction to reduce the opening to the solenoid valve 312 of the electromagnetic heating device 3, and the oil pump 314 inputs less high-temperature oil to the oil inlet end 52 of the heat dissipation coil 5, thereby reducing the heat exchange amount of the heat dissipation coil 5 and reducing the temperature in the box 101; when the temperature of the box 101 is lower than the preset constant temperature threshold of 30°C, the PLC control module 43 sends a control instruction to increase the opening to the solenoid valve 312 of the electromagnetic heating device 3, and the oil pump 314 inputs more high-temperature oil to the oil inlet end 52 of the heat dissipation coil 5, thereby increasing the heat exchange amount of the heat dissipation coil 5 and increasing the temperature of the box 1 01, through the cooperation of PLC control module 43, thermocouple 1 6, thermocouple 2 7, thermocouple 3 8 and solenoid valve 312, the temperature in box body 101 is always in a constant temperature state of 30°C; under the condition that the box body 101 of planting box 1 is kept at a constant temperature of 30°C, the operator clicks the light on button on the display screen 42 every day, and the PLC control module 43 pre-sets the lighting time for 8 hours. At this time, the PLC control module 43 sends an on control instruction to the control switch of the fluorescent lamp 108.

When the temperature of the box 101 reaches the preset constant temperature threshold of 18°C, the PLC control module 43 sends a control instruction to reduce the opening to the solenoid valve 312 of the electromagnetic heating device 3, and the oil pump 314 inputs less high-temperature oil to the oil inlet end 52 of the heat dissipation coil 5, thereby reducing the heat exchange amount of the heat dissipation coil 5 and reducing the temperature in the box 101; when the temperature of the box 101 is lower than the preset constant temperature threshold of 18°C, the PLC control module 43 sends a control instruction to increase the opening to the solenoid valve 312 of the electromagnetic heating device 3, and the oil pump 314 inputs more high-temperature oil to the oil inlet end 52 of the heat dissipation coil 5, thereby increasing the heat exchange amount of the heat dissipation coil 5 and increasing the temperature of the box 1 01, through the cooperation of PLC control module 43, thermocouple 1 6, thermocouple 2 7, thermocouple 3 8 and solenoid valve 312, the temperature in box body 101 is always in a constant temperature state of 18°C; under the condition of constant temperature of 18°C ​​in box body 101 of planting box 1, the operator clicks the light on button on display screen 42 every day, and PLC control module 43 pre-sets the light time for 8 hours.
