Embodiment Construction
[0045] The technical solution of the present invention will be further described in detail in conjunction with the accompanying drawings and embodiments.
[0046] figure 1 A schematic flow chart of the facility lettuce disease early warning method in this embodiment is shown, as figure 1As shown, a kind of facility lettuce disease early warning method provided by the present embodiment comprises:
[0047] S1, obtaining temperature parameters and humidity parameters within a preset time period in the lettuce planting environment of the facility;
[0048] S2, judging whether the current temperature value in the temperature parameter and the current humidity value in the humidity parameter meet the instant warning condition, and if so, perform an instant warning;
[0049] S3. Calculate the hourly average temperature and hourly average humidity for each hour within the preset time period according to the temperature parameter and the humidity parameter, and judge whether all the...

The invention relates to the technical field of vegetable disease prevention, in particular to a greenhouse lettuce disease early warning method and device. According to the greenhouse lettuce disease early warning method and device provided by the invention, the infestation time is determined in different environments according to an environmental temperature-humidity threshold on which lettuce diseases tend to occur and different pathogens based on a plant disease triangle principle, and early warning includes timely early warning, time integration early warning and short-term early warning. A better effect is achieved in comparison to a single early warning method, the influences of pathogens on the lettuce at the contact period, invasion period, incubation period and disease period can be comprehensively considered respectively, and early warning results are more reliable. Meanwhile, peasant households can understand and grasp conveniently, and convenience is brought to popularization and application.
Description
technical field [0001] The invention relates to the technical field of vegetable disease prevention and control, in particular to an early warning method and device for facility lettuce disease. Background technique [0002] The occurrence of vegetable physiological diseases is related to the adverse environment and the infection of pathogenic organisms. Only the cooperation of pathogenic organisms, host plants and certain environmental conditions can cause diseases, which is the so-called "disease triangle". The three are interdependent and indispensable. , the change of any one of these factors will affect the other two factors. Based on the research on the relationship between vegetables, pathogens and the environment, the establishment of an early warning system for vegetable diseases in facilities can effectively prevent and prevent the occurrence of diseases, ensure the healthy growth of vegetables in facilities, and at the same time guide farmers to take corresponding...
