The Buildup Of The Agricultural Disease Pest And Weed Inquiry System

The paper was built as a software according to the problem existed in the disease pest and weed identification and control the trend to the application of computer in the agricultural science. Our office staffs developed "farmland disease pest and weed information inquiry system" software in order to solved the problem of the main crop disease pest and weed identification, herbicide misapplication and agricultural control. This system, which made use of the ADO technique of Visual Basic to make the expert's knowledge into knowledge database was created by software. It has the stronger inquiry ability and a certain intelligence. Without an expert, you can still identify disease pest and weed, control disease pest and weed at the same time. Visible programming technique together with friendly windows made the operation more vivid, convenient, fast. System supported fuzzy inquiry. Knowledge database can be continuously modified and enlarged along with the knowledge renewed continuously. This system included disease identification subsystem, pest identification subsystem, weed control subsystem.The subsystem identified a disease according to the name, damage symptom and so on, preparing for weed control. The database was arising from the collection of domestic and international book, it included the content of identification of the plant, diseasing. At the same time it contained the plant classification ,plant name, damage classification, damage plant name and IPM, and contents the picture and introduction .The contents were thorough, and operation method was easy and fast.The subsystem identified a pest according to the pest contribution, damage mode, damage site and damage feature. It supplies the inquired information for controlling the pest. The database was arising from the collection of domestic and international book. The customer can freely choose the inquiry method. The system showed the related information of matching the qualification and picture of some construction and the detailed information.The system has the extending ability. It can link the sofrware "farmland weed chemical control system" in the catalogues. This system included weed identification subsystem, herbicide information subsystem, weed control subsystem. You can identify weed and control weed at the same time.
