Abstract In order to study the best machine-transplanted density for stable and high yield of Yongxian 634， a new early indica rice variety， a field comparative experiment with five machine transplanting density treatments was designed. The results showed that the optimum transplanting density of Yongxian 634 was 25 cm × 12 cm， the actual cutting yield is 7 983 kg/hm2， which had great potential for increasing yield.
