为了探索水稻塑盘旱育秧抛植和旱育秧栽培技术对双季稻生育期的影响，在黄山区和黟县两地进行了试验示范。结果表明，抛秧和旱秧栽培对早、晚稻生育进程都有影响，尤其对双季晚稻生育期影响较大，双晚同等条件下比水育秧栽插全生育期推迟４－１２天。 In order to explore the effects of paddy-plastic cultivation of dry cultivation seedlings and cultivation techniques of drought-tolerant rice on the growth period of double cropping rice, experiments and demonstrations were conducted in Huangshan District and Juxian County. The results showed that throwing seedlings and drought-seedling cultivation had an impact on the growth of early and late rice, especially on the growth period of double-season late rice. Compared with the double-late nights, the growth period was delayed 4-12 days than that of aquaculture.
