TL;DR: In this article, an agricultural information processing method, a device and an electronic device, which relate to the technical field of data communication, is presented. The method obtains the geographic position information of cultivated land and the hyperspectral data of crops in current cultivated land.
Abstract: The invention provides an agricultural information processing method, a device and an electronic device, which relate to the technical field of data communication. The method obtains the geographic position information of cultivated land and the hyperspectral data of crops in current cultivated land. Then, according to the geographic position information, the meteorological data corresponding to the geographic position of the cultivated land are obtained. Based on meteorological and/or hyperspectral data, service prompt information corresponding to crops is determined and generated. The invention can reduce the labor of users, reduce the risk of crop loss caused by users' inability to obtain the service prompt in time, and is also helpful to improve the work efficiency of users.

TL;DR: In this paper, a characteristic spectrum index detection system for tussock moth hazard detection comprises a spectrum data acquisition module, a data transmission module, central control module, hazard data model construction module, an alarm module, data storage module and a data display module.
Abstract: The invention belongs to the technical field of tussock moth hazard detection, and discloses a characteristic spectrum index detection system and method for tussock moth hazard detection. The characteristic spectrum index detection system for tussock moth hazard detection comprises a spectrum data acquisition module, a data transmission module, a central control module, a hazard data model construction module, a hazard judgement module, an alarm module, a data storage module and a data display module. Through the hazard data model construction module, a hazard detection model for tussock mothhazard grading can be realized to provide a solution for rapid and correct detection of tussock moth hazards; and meanwhile, through the hazard judgement module, the judgement efficiency is high, thecorrectness is high, and rapid, simple and correct recognition for the tussock moth hazards can be satisfied. Through remote sensing satellite data which can be directly obtained, plant diseases and insect pests can be assessed in a large scale, so that plenty of manpower and material resources are saved, a wide application prospect is provided, and great facilitation is provided for the social life.

TL;DR: In this article, the authors proposed a method for diagnosing crops diseases using the soil temperature/humidity information of a field where crops grow and the image information of crops, extracting image color and texture features from the collected image information, establishing an image disease model of the crops, and finding out disease types and disease control methods in a preset disease-image relationship database.
Abstract: The invention provides a method for diagnosing crops diseases. The method comprises the following steps: collecting the soil temperature/humidity information of a field where crops grow and the image information of crops, extracting image color and texture features from the collected image information of crops, establishing an image disease model of the crops, and finding out disease types and disease control methods in a preset disease-image relationship database of the image disease model and the soil temperature/humidity information. The method provided by the invention overcomes the problem that the disease profile can not be accurately described by a single image feature, improves the accuracy of crops disease diagnosis and increases the diagnosis efficiency.

TL;DR: In this article, a greenhouse lettuce disease early warning method and device is presented, where the early warning includes timely early warning, time integration early warning and short-term early warning.
Abstract: 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.
