Abstract:

（OBJECTIVE）It is positive significance to research machanical transplanting technology for late rice to solve the problem of higher cost and more labor the traditional transplanting by hand; （METHOD）We selected suitable late rice varieties by machine transplanting and carried out the experiments of the rate of nitrogen; （RESULTS）The results showed that Yongyou 6 had a suitable growing period and large panicle by machine transplanting. The grain yield was increased with more transplanting density by machine. The productive panicles were increased with more nitrogen fertilizer , but the total grains per panicle and filled grains was decreased. It is the most suitable planting method that was transplanting density of 13900 hills / 667m2 (30 cm × 16 cm) and nitrogen fertilizer rate of about 11kg per 667m2; （CONCLUSION）Yongyou 6 got higher yield in late season with machine transplanting under higher density and less nitrogen rate.
