Experimental Study on Intelligent Variable rate Fertilization
Zhang Yong-zhi · Journal of Agricultural Mechanization Research · 2003
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.
