王玥明 通讯员 李霖昊 元喆翰）闽赣边界一条田埂，一侧是福建光泽县寨里镇山头村，另一侧是江西贵溪市樟坪畲族乡西排村。\n\n省级科技特派员、[福建省](http:\u002F\u002Fwww.hxnews.com\u002Fnews\u002Ffj\u002F)农科院数字农业研究所副研究员黄献光蹲在田埂上，拨开一丛稻桩。脚下这片700亩再生稻田，头季刚收完，干谷亩产近750公斤，创下光泽县再生稻种植近6年来最佳成绩。\n\n福建省人大代表、浦城闽越山水米业有限公司董事长钟安森喜出望外：“头季这个产量，成本基本回来了，二茬收的就是利润。”但他清楚，这场高山稻田的“极限试验”才刚开篇。\n\n黄献光解释道：“这里海拔超500米，积温先天不足，头季插、收窗口期极窄，是光泽再生稻种植条件最严苛的片区之一。今年偏偏是晚白露，凉得更快，二茬积温够不够，眼下还没底。”\n\n近年来，在山头村和西排村，闽赣五级人大代表跨省搭建联络平台，盘活两村闲置田块。贵溪市人大代表吴世军率先跨省经营，钟安森随后带着“浦城模式”进场，在两村试点优质稻、再生稻和薯稻轮作，已带动闽赣100余名村民增收。\n\n**一张桌上共议出路**\n\n早在20世纪80年代，两村就建立了边界联防机制，一起抓治安、防山火。田埂上闹点矛盾，大伙坐一起聊几句就摆平了。\n\n随着青壮年外出务工，两村先后陷入耕地撂荒、基础设施滞后的困境。再加上山高谷深、田块细碎、气候多变，同一面山坡常出现“坡头降雨坡尾晴”的小气候。山头村党支部书记龚美叶说，农历八月，别处暑气未消，此地气温就转凉，昼夜温差超10摄氏度。过去村民只种单季稻糊口，没人敢种能收两茬的再生稻。\n\n2018年，光泽县在山头村试点“三变”改革（资源变资产、资金变股金、农民变股民），县、镇两级以“拨改投”注入资金，两村将路沟渠坝、零散耕地等折资入股，联合吴世军所在的贵溪大三元实业集团，组建福建绿兴惠民生态农业有限公司。小田并大田，规模化经营的权属关系就此理顺。\n\n但此后，稻田产量平平，效益后劲不足，销路主要靠政府和高校帮扶，没能真正闯入市场。\n\n今年3月，寨里镇人大主席团赴江西贵溪开展跨省人大代表协作对接。座谈会上，全国人大代表、樟坪畲族乡党委书记雷燕琴率先将走访收集的民意摆上桌面：“两村撂荒地怎么治？过去两地虽有往来，但都是零敲碎打，缺系统、缺支撑。要想真正抱团发展，还得两地人大牵头，拧成一股绳干。”\n\n钟安森接过话头：“浦城是福建粮仓，其种粮模式若能落地边界，既能夯实福建粮食安全底盘，也能为跨省产业联动作出探索。”\n\n共识很快达成。两省五级人大代表走上田头，围绕边界农文旅融合示范带建设实地踏勘。这片难种的田里，从此多了一群“编外农民”。\n\n**浦城团队跨界出省**\n\n合作意向敲定后，钟安森第一次到两村高标田施工现场调研，随后直言“像小孩子过家家”：只有小钩机扒拉，不见一台大型推土机。田块高低差怎么处理、水渠怎么走、机耕路怎么铺，施工队全凭感觉干。\n\n他把整个施工队拉到浦城的几个高标田示范基地，实地看什么叫“逢山开路、遇水搭桥”。大伙深受触动，回来后从头改起。\n\n“连片整地只是规模化经营的基础之一。”钟安森说，育种选种、田间管护、统防统治是“软件”，育秧工厂、烘干仓储、碾米加工线是“硬件”，“种、烘、碾、卖，把浦城粮食产业发展的全套成熟体系都搬来。”浦城团队随之进驻，除了种田卖米，还要负责把本地队伍带出来，把产业链扎下去。\n\n今年春耕，浦城闽越山水米业技术管理人员、种粮大户周小荣从育秧开始教起。\n\n龚美叶种了10余年地，早年尝试过引进育秧盘和插秧机。但是，两村的稻田多为半砂质土，如果直接挖来装盘，育出的秧块一抓就散，碎沙石卡住取秧口，机器经常插不下去，还得人工补插秧苗，费工费钱，后来被弃用。\n\n直到周小荣带大家配营养土，龚美叶才恍然大悟：“原来不是机器不好使，是土没配好。”\n\n周小荣接过话：“如果只是种两三百亩，漏插了用人工补一补就过去了。以后连片上千亩，你还雇人一株株补？种大田就像办工厂，每道工序都得做到位。哪道差了，效率上不去，钱就赚不到。”\n\n龚美叶想起2018年绿兴惠民公司刚起步时，300多亩优质稻爆发穗颈稻瘟，近乎绝收，光给村民兜底就赔了30多万元。“以前总是虫飞出来了才急着救，现在跟着浦城种粮大户才明白，种田要懂科学、会管理。今年我最大的收获是脑子里有了一整条线，这比学会哪项技术更要紧。”\n\n8月31日，头季稻收割收尾。最后一块田里，光泽县庆志种植农场负责人江裔军跳上收割机。周小荣站在田埂上，目光紧追割台，见江裔军要转弯，急得大喊：“直走！别回头碾稻桩！”\n\n机器一顿，江裔军探出头来。周小荣指着稻桩：“再生稻就靠它发二茬，你再压，桩就废了。”\n\n江裔军苦笑：“以前种单季稻，收割机在田里随便开，现在多压一下都心疼。”他和朋友合开的农机合作社，今年订单接不停。“忙不过来，打算把儿子从外地叫回来一起干。”\n\n**好米出山游客进村**\n\n8月下旬，再生稻头季丰收。人大代表对接粮储部门提前开仓，梳理收购政策、协调收购指标，不让丰收粮滞留在田头。跨省灌溉水源润泽田间，闽赣巡河交水协作持续深化。\n\n农事展示服务中心动工在即，用地审批、指标缺口等难题，人大代表对接自然资源部门逐项破解；电力杆线影响厂房建设与农机通行，人大代表推动电力部门现场改迁……钟安森说：“人大代表既要提好议案，也要立足本职对接资源、打通堵点，用实干履职，用成效富民。”\n\n山头村闲置的小学将改造成科特派工作站。在钟安森等人大代表的牵线下，寨里镇建起产学研合作机制，引进省农业农村厅、省农科院的专家团队，获得科技支持。\n\n钟安森认为，两村田块看似难种，却有独特优势：水土纯净，海拔高，昼夜温差大，病虫害少，米质出众。“如今大家讲究吃得好、吃得健康，优质稻米市场广阔。我们两条腿走路，再生稻稳产增效，优质稻以质取胜，让闽北好米走出深山，带动边域经济。”\n\n在人大代表们的推动下，两村的农文旅融合示范项目已启动，未来将集水稻种植、精深加工、农耕研学、田园休闲于一体。江西贵溪市青茅境景区是4A级旅游景区，常年吸引北上广等地老年康养游客，距山头村仅17分钟车程。景区客流不少，夜间业态和文旅配套却比较薄弱，寨里镇正好补上短板。“以后江西过来的游客可以白天下田体验农事，看稻作文化展示，晚上在田边看民俗表演和乡村潮牌乐队。”寨里镇人大主席黄建寿说。\n\n秋风拂过田埂，稻浪层层叠叠。这条分隔两省的田埂，如今成了两省人大代表履职的纽带，成为边界群众共富的起跑线。","福建日报
