Description

Technical Field

[0001] This utility model belongs to the technical field of tea tree planting equipment, specifically relating to a temperature and humidity control device for tea tree cutting propagation. Background Technology

[0002] Tea seedling cultivation is a crucial step in tea production. Superior tea varieties and effective seedling cultivation techniques can improve the growth quality and yield of tea trees, ensuring stable tea quality and production. Tea seedling cutting is an effective method of asexual reproduction for tea trees. When taking cuttings, select healthy tea tree branches and cut them into cuttings approximately 10-20 cm long, maintaining certain internodes and removing leaves from the lower part. Then, insert the cuttings into potting soil or a seedbed, maintaining suitable humidity and temperature. After a period of time, the cuttings will root and sprout new buds and leaves, at which point they can be transplanted. During this process, controlling the temperature and humidity of the surrounding environment is critical. Maintaining humidity at 85-90% and temperature at 25-28℃ is beneficial for rapid rooting and sprouting. However, currently used seedling cultivation devices are difficult to use to maintain humidity while controlling temperature. For example, when the temperature is low, raising the temperature will lower the humidity, and watering to increase humidity will lower the temperature. It is difficult to simultaneously control and maintain both temperature and humidity. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a temperature and humidity control device for tea tree cutting propagation.

[0004] This utility model is achieved through the following technical solution:

[0005] A temperature and humidity control device for tea tree cutting propagation includes a seedling shed and a display screen. The display screen is installed on the outside of the seedling shed. The inside of the seedling shed is equipped with seedling beds. Multiple water inlet pipes are suspended above the seedling beds. The outlets of the water inlet pipes are equipped with mist nozzles. Multiple air inlets are provided on one side of the seedling shed, and multiple air outlets matching the air inlets are provided on the opposite side. Electric roller blinds are suspended between the sides of the seedling beds and the side walls of the seedling shed. Heaters and fans are sequentially installed on the air inlets, and exhaust fans are installed on the air outlets. Multiple temperature and humidity sensors are also installed inside the seedling shed.

[0006] Furthermore, the central axis of each set of air inlets and outlets is located below the droplet nozzle.

[0007] Furthermore, the electric roller shutter is installed above the air inlet and outlet, and a distance is left between it and the top of the seedling shed as a ventilation channel.

[0008] Furthermore, when the electric roller shutter is lowered, its bottom contacts the ground inside the seedling shed.

[0009] Furthermore, the temperature and humidity sensor is connected to the display screen for signal transmission.

[0010] Furthermore, the fan is connected to the heater.

[0011] Compared with the prior art, this utility model has the following beneficial effects: 1. This utility model controls the temperature through a fan and a heater, and controls the humidity through a fan and a mist nozzle. At the same time, the direction of airflow is changed by raising and lowering the roller shutter, preventing the humidity from changing when the temperature is adjusted, or the temperature from changing when the humidity is adjusted, so that the temperature and humidity are always kept within a certain range, which is conducive to the rapid growth of the cutting tea seedlings; 2. This utility model displays the temperature and humidity values ​​in the seedling shed through a display screen, so that the managers can quickly grasp the environmental changes in the seedling shed and adjust the temperature and humidity in the shed in a timely manner according to the environmental changes, which is conducive to improving the precise and convenient management of tea seedlings.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the scope of protection of the present invention is not limited by the embodiments. Example 1

[0015] like Figure 1As shown: A temperature and humidity control device for tea tree cutting propagation includes a seedling shed 1 and a display screen 10. The display screen 10 is installed on the outside of the seedling shed 1. The inside of the seedling shed 1 is a seedling bed 6, which is installed on the ground inside the seedling shed 1. The seedling bed 6 is used to cultivate tea tree cuttings. Multiple water inlet pipes 7 are suspended above the seedling bed 6. The water pipes are laid along the upper space of the seedling bed 6, and multiple branch pipes with water outlets hang down to... Above the seedling bed 6, a distance of at least 50cm is maintained to allow space for the cuttings to develop. The water inlet pipe 7 is equipped with a misting nozzle 8, which waters the cuttings and increases the humidity inside the seedling shed 1. The seedling shed 1 has multiple air inlets 3 on one side and multiple air outlets 11 matching the air inlets 3 on the opposite side. The central axis of each set of air inlets 3 and air outlets 11 is located below the misting nozzle 8. Above the seedling bed 6, electric roller blinds 2 are suspended between the two sides of the seedling bed 6 and the side walls of the seedling shed 1. The electric roller blinds 2 are installed above the air inlet 3 and the air outlet 11, and are left with a distance from the top of the seedling shed 1. The space between the electric roller blinds 2 and the side walls of the seedling shed 1 and the space at the top of the seedling shed 1 form an air passage. When the electric roller blinds 2 are rolled down, the bottom of them contacts the ground inside the seedling shed 1 to prevent air from passing through the ground. The electric roller blinds 2 are rolled up or down by a winch driven by a motor. A heater 4 and a fan 5 are installed in sequence on the air inlet 3. The fan 5 is connected to the heater 4. An exhaust fan 12 is installed on the air outlet 11. The inside of the seedling shed 1 is also equipped with multiple temperature and humidity sensors 9. The temperature and humidity sensors 9 are connected to the display screen 10 for signal transmission. The temperature and humidity values ​​monitored by the temperature and humidity sensors 9 are displayed on the display screen 10 in real time for easy viewing by management personnel.

[0016] In practice, tea tree cuttings are inserted into the seedling bed 6. During the cultivation of the cuttings, when the temperature and humidity sensor 9 detects that the temperature inside the seedling shed 1 is below 25℃ and the humidity is below 85%, the electric roller shutter 2 is activated to lower the shutter. Then, the fan 5 and heater 4 are activated. The fan 5 blows out hot air to increase the temperature inside the shed. At the same time, the water inlet pipe 7 is opened, and water is sprayed out as atomized water droplets through the mist nozzle 8 to humidify the inside of the shed. Because the hot air is blocked by the roller shutter, it will not affect the seedling bed 6 inside the roller shutter on both sides. Direct airflow removes less moisture, thus simultaneously increasing humidity during the heating process. If humidity is already maintained at 85-90%, there's no need to open the water inlet pipe 7 for watering due to the roller shutters blocking the hot air. In hot weather, when the greenhouse temperature exceeds 28℃, simultaneously turn on the fan 5 and exhaust fan 12 to circulate air and lower the temperature. If cooling is slow, open the water inlet pipe 7 to spray water for cooling, and simultaneously raise the electric roller shutters 2 on both sides. The exhaust fan 12 can quickly dissipate the high temperature. The hot and humid air generated below is drawn away, causing the seedling shed 1 to cool down rapidly. After the temperature drops to 25-28℃, the electric roller shutters 2 on both sides are lowered, allowing air to circulate from the sides and top of the seedling shed 1. The water inlet pipe 7 continues to spray water, raising the humidity to 85-90%. Then, the water inlet pipe 7 is closed, and the fan 5 and exhaust fan 12 continue to run until the outside temperature drops. If the humidity inside the shed is too low and needs to be increased quickly, the electric roller shutters 2 on both sides can be raised, and the water inlet pipe 7 and fan 5 can be opened simultaneously. The fan 5 will then ventilate the shed. The water droplets sprayed from the drip nozzle 8 can quickly increase the humidity inside the greenhouse by blowing them to various parts of the greenhouse. If the humidity inside the greenhouse is higher than 90%, such as when watering, the electric roller shutter 2 on one side of the exhaust fan 12 can be raised and the exhaust fan 12 can be turned on to remove the moisture inside the greenhouse. If the temperature inside the greenhouse drops during this process, the heater 4 and the fan 5 can be turned on. The roller shutter on the side of the fan 5 can be lowered to block the hot air, which can raise the temperature inside the greenhouse and lower the humidity. However, in actual use, the humidity inside the greenhouse rarely exceeds 90%.
