中新社湖南隆回11月7日电 (向一鹏 陈斌)7日，在湖南隆回县羊古坳镇湖南生物机电职业技术学院再生稻高产攻关基地，湖南省作物协会组织专家测产显示，该基地再生稻再生季亩产560.8公斤，加上头季亩产877.4公斤，周年亩产达1438.2公斤，刷新中国再生稻高产纪录。
据悉，羊古坳以前长期作为袁隆平院士的超级稻高产攻关示范基地，屡创高产纪录。“经过4年攻关，终于实现了再生稻周年亩产从1300公斤向1400公斤的跨越。”该片再生稻田间管理团队负责人王化永说。
再生稻周年亩产要实现突破，关键在于如何减少头季收获时的机械压损率和品种问题。
“普通农户种植再生稻头季收割的机械压损率高达35%，导致再生季平均亩产约200公斤。” 湖南生物机电职业技术学院副院长刘登魁表示，今年羊古坳基地减压损的农艺措施实现重大改进，将机械压损率降到5%以下。“水肥管理是降低压损率的关键，尤其是晒田环节。”
刘登魁介绍，羊古坳基地种植品种甬优4949具有高产、再生季出芽率高、抗性好等特点，结合适早播种、合理密植、病虫害高效防控等组合技术，产量有保证。
上述测产专家组组长青先国表示，目前湖南再生稻种植面积约300万亩，若将羊古坳这套再生稻高产技术推广开来，普通农民种植再生稻周年亩产可达1000公斤左右。(完)
