诏安县双季稻高产优化集成技术

摘要

福建省诏安县2006—2010年建立＂稻稻薯三熟高产技术研究＂示范片,获得显著增产增收,双季年产量突破1 200 kg/667m2。介绍了双季稻推广双季杂交稻、适期播栽、壮秧密植、定量施肥、合理管水、调控三组叶片和防控病虫草等优化集成技术。%The demonstration fields of rice-rice-potato three-cropping high-yielding cultivation techniques were established at Zhaoan county in 2006-2010 and both achieved significant increase in yield and economic income. Grain yield of double cropping rice surpassed 1200 kg/667m2 per year. The optimum integration technology of double cropping rice was introduced including extending double hybrid rice, suitable sowing and transplanting, fostering robust seedling, rational planting density, quantitative application fertilizer, scientific water management, regulating growth of three-group functional leaves and pest and grass control.
