Classification of spore trapping devices and their role in monitoring and early warning of wheat stripe rust
The spore trapping device is a special equipment used by the agricultural plant protection department for crop disease monitoring. It belongs to the measuring instrument. Its main function is to capture the pathogen spores and pollen dust particles that flow with the air, and the purpose is to It is a new type of measuring instrument currently used in agriculture by monitoring the spore stock and its diffusion dynamics to predict and prevent disease epidemics and infections. As far as the way the spore trapper works, it can be divided into the following three categories. 1. Vehicle-mounted spore trapping device: The instrument can be placed on the carrier of bicycles, motorcycles, tool carts, etc., to facilitate the flow monitoring of spores. These three types of spore traps can be used independently or in combination. Unlike fixed spore traps, vehicle-mounted spore traps and portable spore traps are not limited by geography, so they are more flexible to use. Fixed spore trapping devices are often used to monitor the number of spores of diseased pathogens in a fixed area. Although they differ in their working methods, they are really uniform in function and function. The main use of the spore trap is three large blocks, one is the floating matter in the air of the test area; the other is the spore prevention. In the field of treatment, it provides reliable data for pathological research; the third is to collect various pollen to meet the research needs of the application unit. In recent years, through its application, it has also had significant effects on the prevention and treatment of plant diseases. The role of spore trapping instrument in monitoring and early warning of wheat stripe rust In the plant protection work, in order to improve the level of agricultural disease prevention, scientific prevention and control of diseases, and maintenance of the interests of growers, spore trapping instruments are used in many areas to complete monitoring and early warning of plant diseases. Taking wheat planting as an example, in many areas of China, stripe rust bacteria can cause wheat stripe rust and cause considerable loss to wheat production. In recent years, in order to strengthen the monitoring and early warning of wheat stripe rust, spore trapping devices have been used in many areas to monitor the spore amount of stripe rust. At present, the most effective way to prevent and control wheat stripe rust is to use the spore trapping instrument to do a good job of the wheat field census. According to the prevention and control strategy of “taking drugs to detect, discovering one point, controlling one pieceâ€, the diseased spots and disease centers are found. The drug is sealed around it to control its further expansion, and strive to keep the stripe rust hazard to a minimum. From this prevention and control strategy, it can be seen that for the prevention and control of wheat stripe rust, it is generally adopted to prepare early and prevent it in time. According to the plant protection policy of “prevention first, comprehensive preventionâ€, prevention is very important. The spore trapping instrument is used for real-time monitoring of spores of stripe rust, which can timely grasp the development trend of the disease and comprehensively monitor and warn the wheat stripe rust. The application of spore trapping instrument in the prevention and control of modern agricultural diseases provides data support for the staff of the plant protection station to understand the occurrence of spore diseases in a timely manner, so that it can better and more accurately formulate disease prevention and control measures to help better carry out agricultural production. Work to reduce agricultural losses due to pathogenic diseases. Reusable pet pads are a type of absorbent pad that can be used to
protect floors, furniture, and bedding from pet accidents. These pads
are designed to be washable and reusable, making them a cost-effective
and eco-friendly alternative to disposable pads. They come in various
sizes and materials, such as cotton, microfiber, and waterproof layers,
to suit different needs and preferences. Reusable pet pads are also a
great option for pet owners who are trying to reduce waste and minimize
their environmental footprint. Reusable Pet Pads,Washable Waterproof Pet Pee Pad,Washable Pet Urine Pad,Washable Puppy Training Pads Honghu Danielle Sanitary Material Co., Ltd. , https://www.daniellecn.com
2. Fixed spore trapping instrument: This kind of instrument can be fixed in the reporting area to observe the spore type and quantity in a specific area.
3. Portable spore trapping device: The instrument is small, portable and easy to move, and can monitor spores in the area wherever it is.
