摘要
针对当前国内智能化农业的发展现状,开发了一个集成光学传感器和数据控制器的实时自动变量施肥控制系统。该系统可以根据作物的长势实现实时变量施肥。系统利用NDVI(归一化植被指数)测定传感器实时地获取农作物生长的NDVI值,结合作物施肥的不同生长时期,达到依据作物长势实时变量施肥的目的。为此,对控制系统的设计和具体的施肥方案进行了详细的介绍。
In this paper,aiming at the current development of domestic intelligent agricultural,developed a fertilizer application system with automatic vaiables which integrated optical sensing and data controller.This system realize the real time variable rate fertilizer by the crop growth.According to the real-time value of NDVI （normalized difference vegetation index） from NDVI equipment and the different fertilization program,the real time variable rate fertilizer was realized.The control system design and specific fertilization program has been introduced in detail.
