陕西省主要农作物病虫害计算机管理系统（SCDPM）

SCDPM是陕西省小麦、玉米、粟、棉花、油菜病虫害的计算机管理系统，是为植保推广人员设计的。当用户输入简单初始数据后，即可直接获得未来病虫为害程度和何时应采取的防治措施。共包括1个主程序15个子程序，占用15K，外加数据贮存。经过三年验证后，现已开始投入生产试用。

SCDPM-COMPUTER BASED CROP PEST AND DISEASE MANAGEMENT SYSTEM IN SHAANXI PROVINCE,CHINA

This paper reports a simplified computerized pest and disease management system for wheat, maize, millet, cotton and rapeseed crops in Shaanxi province (Shaanxi Crop Disease and Pest Management System), hoping to furnish some useful tools to the extension personnel in the field of plant protection.The pests and diseases concerned are wheat midge, wireworm, wheat gibberella, oriental army worm, greasy cutworm, cotton aphid, carmine spider mite, millet stem borer, meadowy moth and rapeseed virus. Inputs are densities and growth stages of pests, diseases, their natural enemies and the corresponding host plants, and the current and forthcoming meteorological conditions. Outputs are given as predictions of future scale of diseases and pests and optimal measures at the recommended time. It includes one main routine and fifteen subroutines occupying 15K, not including the data bank. In the 3 years of experiment, validation results are promising and risk rates are below 10 percent.
