Description

Technical Field

[0001] This utility model belongs to the field of rice blast inoculation and disease development culture technology, specifically relating to an integrated rice blast inoculation and disease development culture device. Background Technology

[0002] Rice blast is an important fungal disease of rice caused by the blast fungus *Pseudomonas oryzae*. It is characterized by frequent occurrence, rapid spread, and severe damage, and is a significant factor limiting rice yield and quality. To study the pathogenicity of rice blast, screen resistant varieties, and evaluate control measures, artificial inoculation experiments are usually conducted under controlled conditions.

[0003] Conventional manual inoculation devices are mostly simple in structure, with insufficient precision in controlling conditions such as temperature, humidity, light and ventilation, poor heat insulation performance, and lack of integrated spray and environmental control systems, resulting in poor repeatability of rice blast inoculation and disease development and inconvenient operation. Utility Model Content

[0004] The purpose of this invention is to provide an integrated rice blast inoculation and disease development culture device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated rice blast disease inoculation and disease cultivation device includes a cultivation chamber and a first double-layered glass structure. The first double-layered glass structure is mounted on the top of the cultivation chamber, and a second double-layered glass structure is located below the first double-layered glass structure. An insulation layer is provided between the second double-layered glass structure and the first double-layered glass structure. Ventilation holes are provided on the rear surface of the cultivation chamber. A cultivation operation table is horizontally mounted in the middle of the cultivation chamber. An inoculation compartment rack is located below the cultivation operation table, and a spray assembly is mounted above the cultivation operation table. An air conditioning unit is installed on one side of the cultivation chamber. A water pipe is connected to one side of the spray assembly, and a control water valve is installed at the end of the water pipe away from the spray assembly.

[0007] Furthermore, the heat insulation layer is disposed in the middle of the first double-layer glass structure and the second double-layer glass structure and is used to provide heat insulation, and the ventilation hole array is opened on the rear surface of the culture chamber.

[0008] Furthermore, both the first and second double-layer glass structures are inclined to prevent dust residue and facilitate drainage, and the cultivation operating table is made of marble.

[0009] Furthermore, the inoculation compartment frame assembly includes a partition plate, an adjusting slider, a positioning bolt, and a support rail. The left and right sides of the partition plate are symmetrically connected with adjusting sliders, and the side of the adjusting slider is horizontally installed with a positioning bolt. The side of the adjusting slider away from the partition plate is vertically connected with a support rail.

[0010] Furthermore, the spacer plate and the adjusting slider are integrated into a single structure, and the adjusting slider and the support guide rail are connected by a slotted embedded structure.

[0011] Furthermore, the spray assembly includes a pipe assembly, atomizing nozzles, connecting pipes, and support frames. The atomizing nozzles are vertically mounted in an array in the middle of the pipe assembly, and the connecting pipes are horizontally connected to the middle of the side of the pipe assembly closest to the water pipe. Support frames are symmetrically mounted at both ends of the pipe assembly.

[0012] Furthermore, the connecting pipe and the water pipe are connected by a quick-connect structure, and the pipe assembly and the atomizing nozzle are connected by a quick-connect structure, as are the spray assembly and the control water valve.

[0013] Furthermore, the upper end of the water pipe extends horizontally through one side surface of the culture chamber, and the end of the support frame away from the pipe assembly is installed on the inner wall surface of the culture chamber.

[0014] The integrated rice blast disease inoculation and disease cultivation device provided by this utility model has the following beneficial effects:

[0015] 1. This utility model, through the integrated design of a cultivation chamber, a first double-layered glass structure, a second double-layered glass structure, an insulation layer, ventilation holes, a cultivation operating table, an inoculation compartment rack assembly, a spray assembly, an air conditioning unit, water pipes, and control valves, constructs a fully functional and convenient rice blast inoculation and disease development environment. The cultivation chamber, as the core space, is a rectangular three-dimensional structure supported by a metal frame. The first and second double-layered glass structures are installed around the chamber and on its top, providing not only excellent heat insulation performance but also ensuring uniform light distribution within the chamber, thus ensuring the rice grows healthily during inoculation and development. Sufficient sunlight during the disease period, while avoiding direct sunlight, is beneficial to the healthy growth of rice seedlings. The insulation layer further enhances the heat preservation effect of the device, reducing the impact of the external environment on the internal temperature and providing stable environmental conditions for rice blast inoculation and disease development. The array design of ventilation holes effectively promotes air circulation in the cultivation chamber, avoids local accumulation of pathogens, and also helps to regulate indoor humidity. This controls air circulation, preventing the entry of external dust or bacteria while maintaining internal gas exchange, simulating a natural ventilation environment, and meeting the precise control requirements of environmental conditions for rice blast research.

[0016] 2. The cultivation workbench in this utility model is made of marble, which is not only flat, sturdy, and corrosion-resistant, but also easy to clean, maintaining a good experimental hygiene environment. Its excellent thermal conductivity also helps maintain a stable temperature on the workbench, providing a stable and reliable working platform for inoculation operations. The design of the inoculation compartment rack group, through the coordination of adjustable sliders and support rails, allows for flexible adjustment of the height and spacing of the partition plates, meeting the placement requirements of rice plants under different experimental needs, improving the flexibility and efficiency of the experiment, and facilitating the provision of the dark conditions required for rice blast fungus infection.

[0017] 3. The spray assembly in this invention employs a combination design of pipe assembly, atomizing nozzle, connecting pipe, and support frame, ensuring uniform water mist spraying and providing the necessary moisture conditions for rice blast inoculation. The application of a quick-connect structure simplifies the installation and disassembly process of the assembly, improving the convenience of experimental operation. The control water valve allows for more precise water volume adjustment, helping experimenters adjust the spray volume according to actual needs, further enhancing the accuracy and controllability of the experiment. In addition, the fine and uniform droplets sprayed from the atomizing nozzle can quickly increase indoor humidity without directly impacting the plants, thus providing a suitable high-humidity environment for rice blast fungus infection. The spray system is connected to the control water valve and can be started and stopped according to the indoor humidity range to achieve dynamic humidity balance. Attached Figure Description

[0028] like Figures 1 to 5 As shown, the integrated rice blast inoculation and disease cultivation device provided in this application includes a cultivation chamber 1 and a first double-layer glass structure 2. The first double-layer glass structure 2 is mounted on the top of the cultivation chamber 1, and a second double-layer glass structure 3 is arranged below the first double-layer glass structure 2. A heat insulation layer 4 is arranged inside the second double-layer glass structure 3 and the first double-layer glass structure 2. A ventilation hole 5 is opened on the rear surface of the cultivation chamber 1. A cultivation operation table 6 is horizontally mounted in the middle of the cultivation chamber 1. An inoculation compartment rack 7 is arranged below the cultivation operation table 6, and a spray assembly 8 is mounted above the cultivation operation table 6. An air conditioning unit 9 is installed on one side of the cultivation chamber 1. A water pipe 10 is connected to one side of the spray assembly 8, and a control water valve 11 is installed at the end of the water pipe 10 away from the spray assembly 8.

[0029] It should be noted that the insulation layer 4 is located in the middle of the first double-glazed structure 2 and the second double-glazed structure 3 and is used to provide heat insulation. The ventilation holes 5 are arrayed on the rear surface of the culture chamber 1. The first double-glazed structure 2 and the second double-glazed structure 3 are both inclined to prevent dust residue and facilitate drainage.

[0030] The cultivation workbench 6 is made of marble. The marble surface of the cultivation workbench 6 is smooth and flat, which makes it difficult for bacteria to grow, thus providing a clean operating platform for rice blast inoculation experiments.

[0031] Air conditioning unit 9, as the core of the environmental control system for the entire device, can precisely control the temperature and humidity within the cultivation chamber 1, providing stable environmental conditions for the inoculation, disease development, and cultivation of rice blast. The control valve 11 allows researchers to precisely adjust the spray volume according to actual needs, further improving the accuracy and controllability of the experiment. Through the coordinated work of its components, the entire device provides a fully functional and easy-to-operate experimental platform for the study of rice blast.

[0032] In some embodiments, the inoculation compartment rack assembly 7 includes a partition plate 701, an adjusting slider 702, a positioning bolt 703, and a support rail 704. The left and right sides of the partition plate 701 are symmetrically connected to the adjusting slider 702, and the positioning bolt 703 is horizontally installed on the side of the adjusting slider 702. The side of the adjusting slider 702 away from the partition plate 701 is vertically connected to the support rail 704. The partition plate 701 and the adjusting slider 702 are integrated into one structure, and the adjusting slider 702 and the support rail 704 are connected by a slotted embedded structure. Through its unique structural design, the partition plate 701 can be flexibly adjusted in height and spacing according to experimental needs. The adjusting slider 702 slides smoothly on the support rail 704, and the positioning bolt 703 ensures the stability after adjustment, providing stable support for rice plants and facilitating the creation of the dark environment required for rice blast infection.

[0033] Specifically, the aforementioned spray assembly 8 includes a pipe assembly 801, an atomizing nozzle 802, a connecting pipe 803, and a support frame 804. The atomizing nozzle 802 is vertically mounted in the middle of the pipe assembly 801, and the connecting pipe 803 is horizontally connected to the middle of the side of the pipe assembly 801 near the water pipe 10. Furthermore, the support frames 804 are symmetrically mounted on both the left and right ends of the pipe assembly 801. The connecting pipe 803 and the water pipe 10 are connected by a quick-connect structure.

[0034] In some embodiments, the pipe assembly 801 and the atomizing nozzle 802 are connected by a quick-connect structure, and the upper end of the spray assembly 8, the control water valve 11, and the water pipe 10 are horizontally inserted through one side surface of the cultivation chamber 1. The end of the support frame 804 away from the pipe assembly 801 is installed on the inner wall surface of the cultivation chamber 1. The atomizing nozzle 802 sprays fine and uniform droplets, which can quickly increase the humidity in the cultivation chamber 1 and create favorable conditions for the infection of rice blast fungus.

[0035] As some preferred solutions, the connecting pipe 803 and the water pipe 10, and the pipe assembly 801 and the atomizing nozzle 802 are all connected by a quick-connect structure, which makes the installation and disassembly process simple and quick, improves experimental efficiency, and the support frame 804 is firmly installed on the inner wall surface of the culture chamber 1, providing reliable support for the spray assembly 8.

[0036] In summary, when using the integrated rice blast inoculation and disease development culture device of this application, first place the entire device in a suitable experimental site to ensure that it is level and stable. Then, by adjusting the cooperation between the slider 702 and the support rail 704, adjust the height and spacing of the interval platform 701 according to the experimental requirements to provide suitable placement space for the rice plants. Subsequently, turn on the air conditioning unit 9 and set the temperature and humidity parameters in the culture chamber 1 according to the experimental requirements to create stable environmental conditions for rice blast inoculation and disease development.

[0037] Meanwhile, the water output of the spray assembly 8 is adjusted using the control water valve 11 to ensure that the atomizing nozzle 802 can spray a fine and uniform water mist, providing a suitable high-humidity environment for the infection of rice blast fungus. During the experiment, the array design of the ventilation holes 5 can effectively promote air circulation in the cultivation chamber 1, avoid local accumulation of pathogens, and regulate the humidity inside the chamber, simulating a natural ventilation environment. The first double-layer glass structure 2 and the second double-layer glass structure 3 provide good heat insulation performance and ensure uniform distribution of internal light, providing sufficient and suitable light conditions for rice during inoculation and disease development, avoiding damage to rice seedlings caused by direct sunlight, and promoting the healthy growth of rice seedlings. The insulation layer 4 can further enhance the heat preservation effect of the device, meeting the precise control requirements of environmental conditions for rice blast research.

[0038] When inoculating with rice blast fungus, researchers can operate on the culture workbench 6. Its flat, sturdy, corrosion-resistant, and easy-to-clean properties maintain a good hygienic experimental environment. Simultaneously, the design of the inoculation compartment rack 7 facilitates the provision of the dark conditions required for rice blast fungus infection, ensuring a smooth inoculation process. After the experiment, the quick-connect structure simplifies the disassembly of the spray assembly 8, facilitating cleaning and maintenance. Furthermore, the integrated design of the entire device not only simplifies the experimental procedure and improves efficiency but also enhances the repeatability and reliability of experimental results through precise environmental control, providing strong support for rice pathology research and breeding resistance identification experiments.
