In order to improve rice fertilizer utilization and reduce pollution, a field test was conducted to study the effects of fertilizer application rate of synchronized side-deep fertilization technology on yield and fertilizer use efficiency of machine-transplanted rice, using N Liangyou 1998 and Wanxiangyouhuazhan as materials. The results showed that the synchronized side-deep fertilization technology could increase the number of tillers, grain yield and fertilizer use efficiency. The combination treatment with reduce 20% of tillering fertilizer and synchronized side-deep fertilization technology was the best. Compared with the wind feeding method, the screw side deep fertilization method has better effect.
Key words: rice; machine-transplanted seedling; side deep fertilization
