The Design of the Variables Fertilization Test- bed

Soil is a most important resource of agricultural, fertilizers is the material base to developing ag- ricultural. One of the most important factors for the fertilized effect is fertilizer ejector. At present, putting a more and more high demand on quality of fertilize . This article mainly introduced the development of variable rate fertilization at home and abroad ,the problems and the future development directions,at the same time, made a briefly explain for the test -bed that designed for variables fertilization about struc- ture,test principle and the selection of key components and design.
