Fertilizers play a vital role in agriculture.The fertilization machinery is the basic implement for rational application of fertilizer.It was analyzed the principle and development of application machinery for solid fertilizer(centrifugal disc spreader,blade type spreader,hammer distributor fertilization machines),liquid fertilizer,variable rate application and fertigation.It is pointed out that the large scale,intelligence machines are the developing direction of the international fertilizer machinery.Development of fertilizer applicators in China was also analyzed.The common machines for fertilizers were the spreaders.Seeding and fertilizing machines in China were developing in recent years.Disc type seeding and fertilizing machines for wheat and corn seeding and fertilizing machine were the two main types.In recent years,fertigation was developing very fast in China.Because of high dispersion and high strength development,the utilization of mechanical fertilization is difficult for small scale management,and the technical transformation rate is lower.According to the developing trends of Chinas agriculture,to improve the fertilizer utilization rate,reduce the loss of the nutrients,the development of fertilization machines will be focus on deep application,topdressing fertilization,variable rate application,nearing root application and liquid fertilizer and so on.
