玉米精确施肥系统的研究与应用

Research and Application of the Maize Precise Fertilization System

以玉米施肥为突破口,将人工智能技术与全球定位系统(GPS)和地理信息系统(GIS)技术相结合,以玉米养分平衡法数学模型为核心,采用面向对象技术,开发研制了玉米精确施肥专家系统。该系统主要解决玉米产量预测和精确施肥2大问题,最终为用户打印出包含预测产量、推荐品种、建议施肥量、效益分析情况在内的玉米精确施肥咨询单。该系统的应用可降低玉米生产成本,使农民增产增效,实现低投入高产出。

In order to study the fertilizer quantity to maize, which was influenced by production level of different areas and nutrition of soil, we developed the maize precise fertilization expert system by combining the artificial intelligence techniques, GPS and GIS, with the fertilization for break, taking the mathematics model of nutrient equilibrium as the core, and adopting the object-oriented progrmnming technology. The system mainly resolves the two problems of yield prediction and precise fertilization and ultimately print for the user the consultation sheet of maize precise fertilization, including predicted yield, variety, fertilizer quantity and the situation of benefit analysis. The practice result has showed that the application of this system could reduce cost, make present increase yield and benefit, and realize low cost but high production.
