Description

Technical Field

[0001] The utility model relates to the technical field of powdery mildew inoculation devices, in particular to a wheat powdery mildew inoculation device. Background Art

[0002] Wheat powdery mildew is a fungal disease caused by the wheat-specific form of the powdery mildew fungus of the Poaceae family, which mainly harms wheat leaves. According to statistics from the National Agricultural Technology Extension Center, the average annual occurrence area of ​​wheat powdery mildew in my country in the past 10 years is about 100 million mu. When the disease is severe, it can cause a 30-40% reduction in wheat production, seriously reducing the yield and quality of wheat. Due to the synergistic resistance between the toxicity of powdery mildew fungi and host resistance, single-resistant varieties generally lose their resistance after a few years of use in production. Therefore, it is necessary to continuously explore new powdery mildew-resistant wheat germplasm resources and utilize them to improve the powdery mildew resistance of wheat varieties in production. Through the wheat powdery mildew inoculation test, the toxic effects of different wheat powdery mildew physiological races on wheat varieties can be identified, and at the same time, wheat materials resistant to powdery mildew can be screened out, providing excellent disease-resistant germplasm resources for wheat production, and laying the foundation for analyzing the disease resistance mechanism of wheat powdery mildew and better utilizing powdery mildew-resistant materials.

[0024] Before the test, the wheat samples are placed in multiple test chambers 4 at the same time and the partition 3 is taken out so that multiple groups of wheat samples are cultivated under the same conditions for a period of time. When preparing for the test, the partition 3 is placed in the box 1, the humidification mechanism is used to adjust the humidity in the box 1, the temperature adjustment device 13 is used to adjust the temperature in the box 1, and the medicine pot 6 is used to hold powdery powdery mildew bacteria. During the test, the powdery powdery mildew bacteria are placed in the medicine pot 6, and then the sealing cover 10 is used to seal the medicine pot 6. The medicine pot 6 is pressurized by the pressurizing mechanism. When pressurizing, the first valve 8 is in a closed state. When the pressure reaches a certain pressure, the first valve 8 is opened, and the powdery mildew bacteria in the medicine pot 6 will be sprayed from the powder nozzle 9 to the wheat sample to inoculate the powdery mildew.

[0025] Considering that wheat powdery mildew is a living culture, the suitable disease conditions are temperature 15-20°C and humidity>70%. Furthermore, the above also includes a controller for controlling the operating state and operating power of the temperature regulating device 13 and the humidifying mechanism. A temperature and humidity sensor 5 connected to the controller is provided in the test chamber 4. During the test, the controller stores the temperature range value of 15-20°C and humidity value>70% when the wheat powdery mildew is cultivated alive. The temperature and humidity sensor 5 feeds back the temperature and humidity information in the test chamber 4 to the controller in real time. The controller adjusts the operating state of the temperature regulating device 13 and the humidifying mechanism and the operating power in real time according to the received temperature and humidity information to make the temperature in the test chamber 4 be 15-20°C and the humidity>70%.

[0026] As a preferred embodiment of the above embodiment, the pressurizing mechanism includes an air pump 14, which is connected to the medicine pot 6 through a pressure air pipe 15. The medicine pot 6 is fixedly connected to the box body 1 through a support rod 16. After the air pump 14 is started, air is supplied to the medicine pot 6 through the pressure air pipe 15. The powdered pathogens in the medicine pot 6 are not easy to be excessive, and are prevented from entering the pressure air pipe 15.

[0027] As a preferred embodiment of the above embodiment, the box body 1 is also equipped with a spray mechanism for increasing the humidity of the test chamber 4. Specifically, the spray mechanism includes a main pipe 17 connected to a water source, a second valve 18 is provided at the liquid inlet end of the main pipe 17, a discharge section has a main and branch pipe 19 extending into the test chamber 4, and a water mist nozzle 20 is connected to the discharge end of the branch pipe 19 at the top of the test chamber 4. The water source enters the branch pipe 19 through the main pipe 17 and is then sprayed out through the water mist nozzle 20. The second valve 18 is used to control the water flow of the main pipe 17.

The air intake pipe 28 is provided with a first filter box 23. The hot air in the temperature regulating device 13 enters the test chamber 4 through the air supply pipe 22 to increase the temperature of the test chamber 4, so that the wheat is maintained at a suitable temperature. The first filter box 23 is used to filter impurities in the external air to reduce the impact of the external air on the test chamber 4.

[0030] As a preferred embodiment of the above, an exhaust pipe 24 is provided on the top of the test chamber 4, and a one-way valve 27 and a second filter box 25 are installed on the exhaust pipe 24. When the gas pressure in the test chamber 4 increases, the gas enters the second filter box 25 through the exhaust pipe 24 and the one-way valve 27, and is discharged after being filtered by the second filter box 25. The second filter box 25 prevents powdery mildew fungi from being discharged from the test chamber 4, thereby reducing the impact on the external environment.

[0031] As a preferred solution of the above embodiment, a holder 26 is fixed at the bottom of the test chamber 4 , and a cultivation box 29 is placed on the holder 26 . The cultivation box 29 is used to grow wheat, and the holder 26 is convenient for installing the cultivation box 29 .

At this time, the partition 3 is taken out, so that multiple groups of wheat samples are cultivated under the same conditions for a period of time. The water flows into the branch pipe 19 through the main pipe 17, and then sprayed out through the water mist nozzle 20 to adjust the humidity in the test chamber 4. The hot air in the temperature regulating device 13 enters the test chamber 4 through the air supply pipe 22 to adjust the temperature in the test chamber 4 so that the wheat is kept under suitable temperature and humidity conditions for powdery mildew inoculation. The first filter box 23 is used to filter impurities in the external air to reduce the influence of the external air on the test chamber 4. When preparing for the test, the powdery mildew fungus is poured into the medicine pot 6, and then the sealing cover 10 seals the medicine pot 6. After the air pump 14 is started, air is supplied to the medicine pot 6 through the pressure air pipe 15. When pressurized, the first valve 8 is in a closed state. When the pressure reaches a certain pressure, the first valve 8 is opened, and the powdery powdery mildew fungus in the medicine pot 6 will be sprayed from the powder nozzle 9 to the wheat sample. After a period of time, the changes in wheat can be observed.
