Abstract: In order to explore the effects of different harvesting methods in main crop on growth and yield of regenerated rice,rice variety “Huanghuazhan” was used as experiment material,and main crop was harvested by machine and labor with stubble height 20 cm,40 cm,60 cm respectively in 2017. The results showed that whether machine-harvested or hand-harvested, the growth duration of regenerated rice with same stubble height was same. Ranging from 20 cm to 40 cm of stubble height, the growth period of regenerated rice with low stubble height was more later than that of regenerated rice with high stubble height. Regenerated rice with stubble height of 40 cm had better yield. The yield of regenerated rice with height of 40 cm by hand-harvested in main crop was the highest, up to 4 881.5 kg/hm2.

Key words: harvesting methods of main crop, regenerated rice, growth, yield
