Application of Vehicle-borne Spore Catchers in Monitoring and Prevention of Larval Alzheimer's Disease
The prevention and control of forest pests and diseases is an important part of the development of forestry ecology. To do this work, it is crucial to carry out pest and disease monitoring as soon as possible. For example, in the critical period of disease prevention and control, vehicle-borne spore traps and other monitoring instruments are used to timely conduct spore capture monitoring of larch caving organisms, which can help plant protection personnel to accurately and timely master the spores of larch falling-off disease in forest areas. The law of occurrence and the prosperous period of dispersal were taken, and preventive measures were taken in due course to minimize the hazards of larch falling sickness. Larix caducity is one of the most important diseases in forestry production. It is more common in natural forests and artificial forests. The disease occurs once a year, with ascospores being the main source of infection. If we do not seize the optimal timing of prevention and control of the disease, not only the cost of prevention will greatly increase, but it will also cause serious irreparable damage to forestry production. Therefore, according to the characteristics of the incidence of larch cavalcade, we use vehicle-borne spore traps to strengthen the monitoring of spores of larch caving. This is to grasp the dynamics of larch conditions, formulate scientific control programs, and improve the control effect of larch caving. An important step. The vehicle-borne spore catcher is a small, portable spore catcher type that can be placed on bicycles, motorcycles, and vehicle carriers for exercise monitoring. Due to the characteristics of large area of ​​forestry and complex diseases, the use of vehicle-borne spore traps for flow monitoring can compensate for the lack of monitoring of fixed spore traps and greatly increase the monitoring effect. The application of vehicle-borne spore traps in the monitoring and prevention of larch cavalage disease provides scientific and effective prevention and control data for prevention and control. Plant protection personnel use the vehicle-borne spore catcher to automatically capture and collect spores scattered in the air. Then the replaced slides are brought back to the room for identification in the microscope, and observations, collections, records, summaries, etc., are performed to capture spores. When it reaches 100/cm, it means that prevention work needs to be carried out immediately.
