王伟在察看稻谷品质。\n\n一粒种子，能改变什么？答案，写在八月的四川田野里：金色稻浪从南到北翻起，玉米陆续收割归仓，又是一季好“丰”景。然而，极端天气频袭，消费需求迭变，曾经熟悉的老品种正加速退出，一茬又一茬的新品种陆续登场，一场“品种革命”正在田垄间上演。种子是农业的“芯片”。今年是“十五五”开局之年，种业振兴行动由“五年见成效”迈向“十年实现重大突破”的关键一年。即日起，四川农村日报全媒体推出《天府问“芯”》系列报道。我们走进测产一线和观摩现场，在田埂间寻找答案：种植户为什么换种？育种专家凭什么坚持？种业企业如何破局？敬请关注。\n□四川农村日报全媒体记者 徐灿红 文\u002F图\n\n 8月15日，乐山市夹江县黄土镇，夹江县正旭粮食专业合作社的稻田里一片金黄。几台收割机在烈日下轰鸣穿梭，合作社负责人王伟来到烘干仓库，看着不断堆高的稻谷，嘴角不自觉地上扬。\n\n 当天，乐山市农业农村局组织专家组，对四川省农业科学院水稻高粱研究所和四川金色绿丹种业有限公司在此实施的中熟优质稻“泸香优8136”百亩示范片进行现场测产验收。\n\n遭遇高温天气\n\n结实率仍超80%\n\n “说实话，测产前我心里真没底。”王伟指着测产田块说，“这片地土壤层薄，加之今年遭遇极端天气，我原本对产量不抱什么期望。”今年，他种了1500亩水稻，其中“泸香优8136”试种了100亩。\n\n 王伟口中的“极端天气”，是指7月初以来反复出现的35℃以上的高温。\n\n “你看看，有没有干瘪的？”四川省农业科学院水稻高粱研究所副研究员曹应江钻进稻田，随手扯下一穗稻谷向记者展示。稻穗上很难找到一粒干瘪的谷粒。\n\n “一般水稻抽穗扬花期，连续两天35℃以上高温就会造成损伤；灌浆期遇高温，又会导致逼熟。”曹应江介绍，在今年这样的高温天气下，对照品种的结实率仅65%左右，而“泸香优 8136”的结实率在80%以上。\n\n 测产数据让所有人心服口服。经过专家组现场随机选取3块代表性田块进行全田机收测产，折合干谷平均亩产达767.92公斤。\n\n冒险创新筛选\n\n仅保住两三株种苗\n\n 这个品种凭什么扛住反复高温？曹应江道出背后秘密：“它是在泸州筛选出来的，本身就是耐热品种。在区试中，比对照品种增产 10%以上。”\n\n 谈及选育历程，曹应江打开了话匣子。\n\n 故事要从 2003 年说起。那一年，曹应江的团队在常规筛选基础上，创新采取了种子去壳的方式，“这样能优中选优，挑出外形与品质俱佳的种子。”但去壳后的种子，发芽率降低。次年播种后遭遇骤冷天气，播下的材料仅存活了几株。科研人员小心翼翼地采用枝梗授粉，保住了这些珍贵的材料。这几株矮壮、早熟的幼苗，成了日后“泸香优”系列品种选育的“火种”——“泸香618A”。\n\n 2008 年，“泸香 618A”与“泸恢8258”配组育成的“泸香658”通过审定。2024年，曹应江的团队进一步利用“泸香618A”与“德恢5136”配组，育成“泸香优8136”。\n\n “母本‘泸香 618A’决定了品种的大部分的品质和早熟特性，‘泸香优 8136’的食味品质可媲美‘野香优’；父本‘德恢 5136’则让品种产量更高、品质更优。”曹应江说。\n\n提前一周成熟\n\n解决茬口衔接难题\n\n 除耐高温外，“泸香优8136”141天的全生育期让种植户更为心动——比普通水稻148天左右的生育期提前了整整一周。“别小看这一周。”曹应江给记者算了一笔时间账，“收完水稻，种植户可以马上抢种泽泻，茬口衔接丝毫不紧张。”\n\n 夹江是四川最早收稻谷的产区之一，目前已收获七八成。在夹江，“水稻+泽泻”的稻药轮作模式已经十分成熟：大春种粮保安全，小春种药材要效益。正旭粮食专业合作社早在 2015 年就引进专业烘干设备，烘干的泽泻品质更高，有药企稳定收购。\n\n 然而，茬口衔接一直是悬在种植户头上的难题。“水稻提前一周收，泽泻就能提前一周种。抢出来的时间就是抢出来的效益。”王伟说，泽泻行情对上市时间比较敏感，更早上市能更从容应对市场变化。\n\n 让他更惊喜的是，这个品种的米质与效益。王伟算了一笔细账：“泸香优8136”比以前种的品种每亩多收一成以上，因米质优，每吨还能多卖50至60元。\n\n “产量这么高，明年要扩大种植规模。”他笑着说。不远处，泽泻育苗田块已备好。再过几天，这片刚完成测产的稻田，将迎来新一轮播种。","四川农村日报","2026-08-25T01:00:00Z",{"impact":88,"substance":18,"depth":137,"authority":13,"freshness":250,"relevant":21,"comment":251},5,"报道了耐高温水稻新品种的测产成果，具有省级农业科技进展价值，信息具体且含背景分析，但时效性稍差。",[253],{"name":247,"url":244},[28,27,255,256,257],"水稻高粱所","泸香优8136","高温耐受",{"code":102,"slug":259,"name":260,"path":261,"parent_code":8},"field-crops","大田作物","\u002Ftopic\u002Ffield-crops",[],{"status":264,"locked":14,"version":35,"method":36,"evidence":265},"partial",{"candidates":266,"agricultural_evidence":44,"reason":288},[267,272,278,284],{"code":212,"score":268,"supported":44,"title":269,"abstract":270,"tags":271},11,[214],[214],[],{"code":273,"score":268,"supported":44,"title":274,"abstract":276,"tags":277},"A5",[275],"高粱",[275],[],{"code":279,"score":50,"supported":44,"title":280,"abstract":281,"tags":283},"F1",[],[282],"种业",[],{"code":40,"score":21,"supported":14,"title":285,"abstract":286,"tags":287},[],[],[27],"一级领域明确，二级方向需要细分",[290,291],"四川省农科院
