近日，广东四会罗源镇引进的"旱优78"节水抗旱稻迎来丰收。 与传统水稻相比，节水抗旱稻能节水50%，减少甲烷排放90%。 这一品种，由华南农业大学 节水抗旱稻绿色产业研究院院长、上海市农业生物基因中心首席科学家罗利军带队成功研发。 一直以来，以"超级稻"为代表的高产路线有力保障了国家粮食安全。而罗利军团队另辟蹊径， 从节水抗旱角度出发，把旱稻的节水、抗旱、易种三个特性整合到水稻当中，育成新型稻作类 型，冲破了撂荒地、新改地、山坡地等传统水稻种植"禁区"，为复垦地粮食生产提供全新解决 方案。 基于其环保特性， 团队还向全世界提出水稻"蓝色革命"观点， 即通过创新培育节水抗旱稻， 实现旱种旱管的稻作生产模式，使水稻生产摆脱对水的过度依赖，大幅减少稻田温室气体排 放，促进水稻生产向"资源节约、环境友好"的绿色可持续生产方式转型。 凭借着这股"钝感力"，节水抗旱稻如今已种遍我国大江南北。截至目前，这颗良种累计种植面 积超过3000万亩，覆盖长江上游、中下游稻区以及华南稻区，甚至在云南海拔2000米的地区 都能种植。 更令人振奋的是，这一源自中国的创新品种已进入20多个共建"一带一路"国家，在肯尼亚、马 达加斯加、多哥 ...
