水稻是孟加拉国、印度和缅甸最重要的粮食作物,研究中国超级杂交稻对孟印缅地区的水稻增产潜力,对于保障孟中印缅经济走廊的粮食安全与区域可持续发展具有重要的现实意义。在全面收集孟印缅地区气候、土壤、田间管理信息和农业统计数据的基础上,结合中国籼型杂交稻F优498和丰两优4号的品种信息和区试数据,通过EPIC模型模拟了1996-2005年雨季孟印缅3国在不同情景下的超级稻生产潜力,并分析了孟印缅地区主要胁迫因子对超级稻单产潜力的影响。研究表明：（1）中国超级杂交稻在孟印缅地区2000年的灌溉和施肥水平下单产潜力为10.22 t/ha,在充分灌溉且合理施肥的水平下单产潜力为11.33 t/ha。（2）孟印...

In this study, information is collected from statistics on the weather, soils, field management and agriculture in the Bangladesh, India and Myanmar (BIM) region. Crop growth parameters within the EPIC (Environmental Policy Integrated Climate) model are calibrated using cultivar data and regional experimental records of indica hybrid rice Fyou498 and Fengliangyou4 in China. Potential yields of rice are then simulated in the BIM region from 1996 to 2005. The effects of local irrigation and fertilization levels on super hybrid rice yield are exam...
