智能变量施肥技术初步试验研究

Experimental Study on Intelligent Variable rate Fertilization

结合承担的精确农业变量施肥技术研究项目，提出了智能变量施肥技术体系和实现方法。利用美国MAPINFO公司MapInfoProfession6.0地理系信息系统，采用MapBasic语言编程，建立了施肥地理信息与决策系统；利用89C52单片机实现智能变量施肥机控制系统。试验表明，研制的智能变量施肥机能够实现精确农业信息控制自动变量施肥作业，为精确农业的进一步试验研究提供技术依据。

Based on the research of variable rate fertilization in precision agriculture,the techno-system and its realization of intelligent variable rate fertilization were put forward in this paper.On the basis of MapInfo Profession 6.0,the GIS of precision fertilization and fertilizing decision-making system were set up in MapBasic. The control system of intelligent variable rate fertilizer applicatior was carried out with singlechip 89C52.Tests indicate that the intelligent variable rate fertilizer applicator can meet the demand of info-control variable rate fertilization in precision agriculture. These results provide groundwork for further investigation of precision agriculture technology.
