During flowering stage, leaf cutting, application of ＂920＂ and pollination were conducted; after pollination, bentazon with a certain concentration was sprayed to kill the male parent; and the hybrid rice was harvested mechanically. Before storage, color separation was performed to remove little remaining male parent, thereby achieving whole-process mechanization of hybrid rice seed production. This study introduced mechanized seed production of Xinhunyou No. 6 through mixed- seeding from the aspects including mechanical direct seeding, seeding raising fol- lowed by transplanting and mechanical planting.展开更多
