In order to simplify the cultivation process of wheat stubble rice and promote efficient return of wheat straw, the broadcasting before the wheat harvest and no-tillage cultivation with wheat straw mulching was studied. The results showed that the seeding time of broadcast wheat stubble rice was delayed 32 days than transplanting rice, the delayed days of each growth period decreased gradually with the development of the growth period, the delayed days of seedling stage, tillering stage, heading stage and maturity stage were 31.0 d, 24.7 d, 18.7 d and 12.7 d, respectively. The whole growth stage was shortened 19.3 d. Under broadcasting, the wheat stubble rice has no tillers spikes, compared with transplanting rice, the grains per panicle and 1 000-grain weight were increased by 3.36 grains and 0.27 g, and the yield was decreased by 1.6%. Therefore, the broadcast wheat stubble rice cultivation simplified the cultivation process, reduced the production cost and efficient utilization of wheat straw.
