Abstract: The effects of different planting methods on super rice Yongyou12 were studied. The results showed that there were no significant differences in the whole growth period between machine transplanting and artificial transplanting under the same sowing time; the filled grains were decreased while the effective panicles were increased under machine transplanting. The machine transplanting rice had slow tillering, longer tillering period, higher peak seedling, bigger groups and lower spike rate. The yield between different planting methods was almost equal, but the machine transplanting rice had lower cost, higher economic benefits and lower labor intensity, and suitable for large-scale rice production.
