四川水稻丰产科技工程主推技术模式及应用效果

Main Technology Models and Its Application Effect of Science and Technology Project for High Yielding in Sichuan

针对四川水稻生产突出问题,通过品种优化和综合技术配套集成,分区构建了＂四川盆地麦（油）茬杂交中稻优质高产栽培技术模式＂、＂盆地丘陵杂交中稻抗逆稳产栽培技术模式＂、＂两熟制稻田水稻轻简高效生产技术模式＂三大主推技术模式,在项目区应用效果显著。超高产攻关田平均产量11 733.6 kg/hm2,连续3年超过11 550 kg/hm2的目标产量,并创造了12 802.65 kg/hm2的成都平原高产纪录。2004~2008年,项目核心区、示范区、辐射区累计新增稻谷223 840万kg,新增产值35.61亿元,节支13.83亿元,新增效益49.44亿元。

In view of the prominent question of rice production in Sichuan,by the varieties optimization and the supporting integration of comprehensive technology,three major technology models were constructed based on regions as ＇hybrid rice after wheat（rape） for quality and high-yield cultivation technology model in Sichuan basin,hybrid rice for resilience and stable-yield cultivation techniques model in Sichuan basin and hills and simple and highly efficient technology model for rice production in double-cropping paddy.The main technology models were applied in the project area.The average output was 11 733.6 kg/hm2 more than the target output of 11 550 kg/hm2 for three consecutive years,and created a high-yield record as 12 802.65 kg/hm2 in Chengdu plain.In 2004-2008,the core areas,demonstration areas and radiation areas of the project,accumulated additional 2 238 400 tons of rice,added value of 3.561 billion yuan,saved 1.383 billion yuan,added benefits 4.944 billion yuan were gained.
