Description

Technical Field

[0001] This utility model relates to breeding and cultivation technology devices, and more particularly to a comparative cultivation device for breeding new tomato varieties. Background Technology

[0002] Comparative cultivation is a common method used in tomato breeding. By planting different tomato varieties or lines under the same environmental conditions, comparative experiments are conducted to evaluate their growth characteristics, yield, disease resistance, quality, and other traits, thereby selecting varieties or lines with superior traits.

[0003] In the process of tomato breeding, it is sometimes necessary to change the air humidity of the environment in which different plants are located to simulate the environment of the target area. While using a misting nozzle can quickly increase the air humidity, more water will evaporate into the air rather than be directly absorbed by the soil. Compared with watering the soil directly, it is less efficient in replenishing soil moisture. When watering the soil directly, the water is mainly absorbed by the soil, and only a small amount of water will enter the air through evaporation from the soil surface and transpiration from the plants. Therefore, the effect on increasing air humidity is not obvious and it is not conducive to quickly increasing air humidity.

[0004] Therefore, in view of the situation that while using atomizing nozzles can quickly increase air humidity, it is not very efficient in replenishing soil moisture, and directly watering the soil has little effect on increasing air humidity, a comparative cultivation device for breeding new tomato varieties can be designed. This device can quickly increase the air humidity inside the light-transmitting chamber and quickly wet the soil through the same water supply device during a single watering process. This would improve the working efficiency of the device, reduce its cost, and solve the above problems. Utility Model Content

[0005] In contrast to the problem that using atomizing nozzles to quickly increase air humidity during tomato comparative cultivation, more water evaporates into the air rather than being directly absorbed by the soil. When watering the soil directly, the water is mainly absorbed by the soil, with only a small amount entering the air through evaporation from the soil surface and transpiration from the plants, thus the effect on increasing air humidity is not significant.

[0006] The technical solution of this utility model is as follows: a comparative cultivation device for breeding new tomato varieties, including a light-transmitting chamber; and a switching valve. The upper end of the light-transmitting chamber is rotatably connected to a transparent microporous ventilation cover via a hinge. The switching valve is installed at the rear end of the light-transmitting chamber. A flow guide plug is slidably connected inside the switching valve. An electric push rod is fixedly connected to the upper end of the flow guide plug. An upper water outlet is opened at the front end of the switching valve, and a lower water outlet is opened at the lower end of the switching valve. An upper flow guide groove is opened at the upper end of the flow guide plug, and a lower flow guide groove is opened at the lower end of the flow guide plug. A lower annular water pipe is fixedly connected and connected to the lower end of the switching valve. A spray nozzle is opened at the lower end of the lower annular water pipe. An upper annular water pipe is fixedly connected and connected to the front end of the switching valve, and an atomizing nozzle is installed at the lower end of the upper annular water pipe.

[0007] Preferably, after planting tomatoes in the culture soil in the storage trough, the transparent microporous vent cover is closed. The transparent microporous vent cover allows air exchange between the inside and outside of the light-transmitting chamber, but it will have a certain interception effect on water vapor. Then, when the water flows into the switching valve, the electric push rod pulls up the guide plug to connect the upper water outlet with the upper guide groove, so that the water can enter the upper annular water pipe and enter the light-transmitting chamber in the form of water mist from the atomizing nozzle, so as to quickly increase the air humidity inside the light-transmitting chamber. Then, the electric push rod presses down the guide plug to connect the lower water outlet with the lower guide groove, so that the water can enter the lower annular water pipe and directly pour onto the soil from the spray nozzle to quickly wet the soil.

[0008] Preferably, the upper end of the electric push rod is fixedly connected to a push rod bracket, and the lower end face of the push rod bracket is fixedly connected to the switching valve.

[0009] Preferably, the upper annular water pipe is located above the lower annular water pipe, and the radius of the upper annular water pipe is smaller than that of the lower annular water pipe.

[0010] Preferably, a water supply pipe is installed at the rear end of the switching valve, a water pump is installed at the lower end of the water supply pipe, and the water supply pipe is connected to the outlet of the water pump.

[0011] As a preferred embodiment, the interior of the light-transmitting chamber is equipped with a soil storage trough, and the lower end of the soil storage trough is equipped with a soil isolation plate, which is fixedly connected to the light-transmitting chamber.

[0012] Preferably, the soil barrier is provided with a drain outlet, a waterproof heating wire is installed on the upper surface of the soil barrier, and a sliding frame is slidably connected to the lower end of the soil barrier.

[0013] Preferably, a filter membrane is installed inside the sliding frame, and a water tank is provided at the lower end of the sliding frame, with the rear end of the water tank connected to the water inlet of the water pump.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a switching valve and a guide plug, when water enters the switching valve, the electric push rod pulls the guide plug up, connecting the upper outlet with the upper guide channel. This allows water to enter the upper annular water pipe and enter the light-transmitting chamber in the form of water mist from the atomizing nozzle. Then, the electric push rod pushes the guide plug down, connecting the lower outlet with the lower guide channel. This allows water to enter the lower annular water pipe and directly spray onto the soil from the spray nozzle. In this way, the air humidity inside the light-transmitting chamber can be quickly increased and the soil can be quickly wetted through the same water supply device during a single water supply process. This improves the working efficiency of the device while reducing its cost. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment of a comparative cultivation device for breeding new tomato varieties, including a light-transmitting chamber 1 and a switching valve 3. A transparent microporous ventilation cover 2 is rotatably connected to the upper end of the light-transmitting chamber 1 via a hinge. The switching valve 3 is installed at the rear end of the light-transmitting chamber 1. A guide plug 4 is slidably connected inside the switching valve 3. An electric push rod 5 is fixedly connected to the upper end of the guide plug 4. An upper water outlet 7 is opened at the front end of the switching valve 3, and a lower water outlet 8 is opened at the lower end of the switching valve 3. An upper guide groove 9 is opened at the upper end of the guide plug 4, and a lower guide groove 10 is opened at the lower end of the guide plug 4. A lower annular water pipe 11 is fixedly connected and connected to the lower end of the switching valve 3. A spray nozzle 12 is opened at the lower end of the lower annular water pipe 11. An upper annular water pipe 11 is fixedly connected and connected to the front end of the switching valve 3. The upper annular water pipe 13 has an atomizing nozzle 14 installed at its lower end. After the tomatoes are planted in the potting soil in the soil storage trough 17, the transparent microporous vent cover 2 is closed. The transparent microporous vent cover 2 allows air exchange between the inside and outside of the light-transmitting chamber 1, but it will have a certain interception effect on water vapor. Then, when the water flows into the switching valve 3, the electric push rod 5 pulls up the guide plug 4 to connect the upper water outlet 7 with the upper guide groove 9, so that the water can enter the upper annular water pipe 13 and enter the light-transmitting chamber 1 in the form of water mist from the atomizing nozzle 14 to quickly increase the air humidity inside the light-transmitting chamber 1. Then, the electric push rod 5 presses down the guide plug 4 to connect the lower water outlet 8 with the lower guide groove 10, so that the water can enter the lower annular water pipe 11 and directly pour onto the soil from the spray nozzle 12 to quickly wet the soil.

[0025] Please see Figures 1-5 In this embodiment, the upper end of the electric push rod 5 is fixedly connected to the push rod bracket 6, and the lower end face of the push rod bracket 6 is fixedly connected to the switching valve 3. The electric push rod 5 is used to push and pull the guide plug 4. The upper annular water pipe 13 is set at the upper end of the lower annular water pipe 11, and the radius of the upper annular water pipe 13 is set to be smaller than the radius of the lower annular water pipe 11. The rear end of the switching valve 3 is equipped with a water supply pipe 15, and the lower end of the water supply pipe 15 is equipped with a water pump 16. The water supply pipe 15 is connected to the outlet of the water pump 16. The water pump 16 is used to draw water from the water tank 22 and inject water into the switching valve 3 through the water supply pipe 15.

[0026] Please see Figure 1 and Figure 6In this embodiment, a soil storage trough 17 is provided inside the light-transmitting chamber 1. A soil isolation plate 18 is provided at the lower end of the soil storage trough 17 and is fixedly connected to the light-transmitting chamber 1. The soil isolation plate 18 is used for soil-water separation. A water outlet is provided on the soil isolation plate 18. A waterproof electric heating wire 19 is installed on the upper surface of the soil isolation plate 18. A sliding frame 20 is slidably connected to the lower end of the soil isolation plate 18. The waterproof electric heating wire 19 is used to heat the soil to change the temperature inside the light-transmitting chamber 1 and accelerate the evaporation rate of water in the soil. The filter membrane 21 can be easily replaced by pulling out the sliding frame 20. The filter membrane 21 is installed inside the sliding frame 20. A water tank 22 is provided at the lower end of the sliding frame 20 and the rear end of the water tank 22 is connected to the water inlet of the water pump 16. The filter membrane 21 is used to filter large particulate impurities in the infiltrated water.

[0027] When in use, first pull out the sliding frame 20 and add water to the slot where the sliding frame 20 is installed through the water pipe to replenish the water tank 22. After planting the tomatoes in the soil in the soil storage tank 17, close the transparent microporous ventilator 2. The transparent microporous ventilator 2 allows air exchange between the inside and outside of the light-transmitting chamber 1, but it will have a certain interception effect on water vapor.

[0028] Subsequently, the water pump 16 is used to draw water from the water tank 22 and inject water into the switching valve 3 through the water supply pipe 15. When the water flows into the switching valve 3, the electric push rod 5 pulls up the guide plug 4 to connect the upper outlet 7 with the upper guide groove 9, so that the water can enter the upper annular water pipe 13 and enter the interior of the light-transmitting chamber 1 in the form of water mist from the atomizing nozzle 14, so as to quickly increase the air humidity inside the light-transmitting chamber 1. Then, the electric push rod 5 presses down the guide plug 4 to connect the lower outlet 8 with the lower guide groove 10, so that the water can enter the lower annular water pipe 11 and directly pour onto the soil from the spray nozzle 12 to quickly wet the soil. The water in the soil can penetrate downwards, pass through the soil isolation plate 18 and the filter membrane 21 and return to the water tank 22 to complete the reuse of water, thereby reducing costs.

[0029] The soil separation plate 18 is used for soil-water separation. The slide frame 20 can be pulled out to easily replace the filter membrane 21. The filter membrane 21 is used to filter out large particles of impurities in the infiltrated water. At the same time, the waterproof heating wire 19 is used to heat the soil to change the temperature inside the light-transmitting chamber 1, thereby simulating the temperature of the target area and accelerating the evaporation rate of water in the soil. The evaporated water will be partially intercepted by the light-transmitting chamber 1 and the transparent microporous vent cover 2 to further change the air humidity inside the device.

[0030] Through the above steps, by setting the switching valve 3 and the guide plug 4, when the water flows into the switching valve 3, the electric push rod 5 pulls the guide plug 4 to connect the upper outlet 7 with the upper guide groove 9, so that the water can enter the upper annular water pipe 13 and enter the light-transmitting chamber 1 in the form of water mist from the atomizing nozzle 14. Then, by pressing the guide plug 4 down with the electric push rod 5, the lower outlet 8 is connected with the lower guide groove 10, so that the water can enter the lower annular water pipe 11 and be directly poured onto the soil from the spray nozzle 12. Thus, in one water supply process, the air humidity inside the light-transmitting chamber 1 can be quickly increased through the same water supply device, and the soil can be quickly wetted, so as to improve the working efficiency of the device and reduce the cost of the device.
