Side Deep Fertilization Technology and Device for Rice

Chemical fertilizer is one of important agricultural inputs.There are some problems in traditional fertilizing operation，such as high labor intensity，low fertilizer utilization efficiency，environmental pollution and so on.It has been proved by practice that the way of deeply buried fertilizer at edge of seedling root can improve above situation effectively，it is beneficial to improve rice yield and reduce planting cost.It is popularized as the main agricultural technology in China in recent years，and has great significance in ensuring stability and safety of grain production.Technical mode of side deep fertilization for rice was expounded，research status and applications of side deep fertilization devices of air blown and spiral propulsion type were introduced，and development trend was put forward.
