莲花岛四面环水，身处阳澄湖的怀抱之中，这一项目的生态拦截系统是项目的另一大亮点，也是守 护阳澄湖水质的关键防线。为拦截面源污染，项目团队创新性地修建了生态沟渠，加高了田埂，在梅雨 或暴雨等天气时，加高的田埂能减少60%以上的排水量，有效避免了雨水裹挟养分直接排入河湖。而S 形设计的生态沟渠则像一道"净化长廊"。"沟渠中精心筛选的这些植物对氮磷吸附能力极强，水流缓慢 流经时，这些植物会高效吸收水中的污染物。"李庆魁说，经过净化塘的静置沉淀后，尾水中的氮磷含 量显著降低，出水水质已接近外河水平。 记者了解到，该项目集成了品种改良、土壤修复、休耕轮作、病虫草害绿色防控、绿色加工等多项 技术，形成了一套成熟的绿色生态水稻栽培体系，不仅实现了水稻高质高效生产，更践行了"生产、生 态、生活、生命"的农业理念。市农科院相关负责人介绍，目前该项目已取得显著成效，未来将继续完 善并推动这套绿色生态水稻栽培技术体系惠及更多地区，让更多稻田实现"既产好米，又护碧水"，走向 更加可持续的绿色发展之路。 眼下相城区莲花岛满目金黄，20亩"试验田"随风翻涌稻浪。更引人注目的是，田边蜿蜒伸展的S形 生态沟渠中，美人蕉、梭鱼草等花卉正灿烂绽 ...
