摘要
大面积水稻栽培仍以育苗移(抛)栽为主,两熟区水稻茬后直播栽培技术,采取免(少)耕旱种湿管和专用物质谷草败、粒粒饱进行调控,其立针现青后生长迅猛,有效分蘖期大幅缩短,而有效穗显著增加,结实率明显提高。水稻茬后直播栽培比育苗移(抛)栽更易实现节水、减污、省工、增效的目的。
In the area of two crops per annual, the direct rice seeding techniques with zero （minimum） tillage, dry seeding, wet management, weed killer Gucaobai and growth regulator Lilibao were used after rape/wheat to promote the rapid growth, shorten the effective tillering stage,increase effective spikes and seed percentage. Direct rice seeding could reduce water consumption, decrease pollution and increase efficiency.
