百亿甘薯成就「中国第一甜县」A sweet-potato chain, and a county’s second sweetness
在雷州半岛北部那片温热肥沃的赭红色土地上，藏着「中国第一甜县」——湛江遂溪。这个称号曾经来自甘蔗产业，而今，遂溪人把这份甜蜜从地上延伸到了地下——作为全国冬薯种植大县，甘薯正成为「甜蜜事业」的新主角。
On the warm red earth at the north of the Leizhou Peninsula is Suixi, long called China’s sweetest county. The name once belonged to sugar cane. People here have carried that sweetness underground. As a major winter-potato county, sweet potato is the new lead.
依托热带北缘的光热资源和富含硒、磷、铁等微量元素的火山红土，这里种出的甘薯口感香甜、品质出众。也正是这份天然的品质优势，让小小甘薯发展成了实实在在的富民产业——全产业链产值突破百亿元，稳稳带动10万农户增收致富。
Light and heat at the tropical edge, and a volcanic soil with selenium, phosphorus, and iron, grow a potato that is fragrant and sweet. That quality turned a small crop into an industry: the full chain is worth more than RMB 10 billion, and it raises income for 100,000 households.
规模与品质Scale, and the plant that carries it
种甘薯这件事，遂溪琢磨出了一套自己的打法。
Suixi has worked out its own way of growing it.
我国冬春季鲜薯上市量极少，遂溪正好把这一「空白期」成功转化为自身发展的「黄金档期」。自2019年起，当地陆续有农户尝试冬季种薯并取得成效。为进一步放大优势，遂溪制定印发了《遂溪县甘薯产业提升行动实施方案（2024—2026年）》及土地流转财政奖补方案，连片流转土地80万亩，全面推广「冬种春收」模式，将北方薯区的休耕空档转变为遂溪甘薯的上市窗口。通过「公司+基地+农户」等共建模式，全县已催生近2000家新型农业经营主体投身甘薯产业，其中种植面积500亩以上的大户近80家。以北坡镇为例，该镇甘薯种植规模预计达5.5万亩，总产量13.75万吨，产值约6.88亿元，拥有甘薯种植大户76户，集群效应日益凸显。
Fresh potato is scarce on the market in winter and spring. Suixi turned that gap into its own season. From 2019, households tried winter planting and it worked. The county then issued a 2024–2026 upgrading plan and a subsidy for land transfer, moved 800,000 mu into contiguous blocks, and pushed a winter-plant, spring-harvest model — the north’s fallow months became Suixi’s selling window. Company, base, and household together have brought nearly 2,000 new operators into the crop, close to 80 of them above 500 mu. Beipo alone expects 55,000 mu, 137,500 tonnes, about RMB 688 million, and 76 large growers.
光有规模还不够，得有「好苗子」。遂溪建成全省首家脱毒甘薯苗生产基地，构建起「组培实验室+智能温室+种苗基地」三级育苗体系。目前全县年产高品质薯苗约5亿株，病毒携带率低于1%，带动甘薯亩均产能突破5000斤、增长30%以上。脱毒薯苗不仅满足了本地需求，更远销河南、河北、安徽、新疆等全国23个省份。
Scale is not enough without clean seed. Suixi built Guangdong’s first virus-free seedling base, in three steps: a tissue-culture lab, a smart greenhouse, and a nursery. The county produces about 500 million good seedlings a year, with virus carriage under 1 percent. Yield per mu has passed 2,500 kilograms, up more than 30 percent. The seedlings also go to 23 provinces, including Henan, Hebei, Anhui, and Xinjiang.
品种也在不断更新。过去「普薯32号」（西瓜红）一统天下，如今广薯、济薯、湛薯系列及丝滑、人参薯等特色品种百花齐放。湛江市农业科学研究院选育的「湛薯12」凭借香甜粉糯的口感和高达81%的大中薯率，兼具中抗薯瘟病特性，在鲜食型甘薯中脱颖而出。高端品牌「火山红薯」则打出「海鲜鱼肽蛋白精准滴灌」的独特种植理念，不仅获评「全国名特优新农产品」，还入选「粤字号农业品牌」「广东十大名薯」等目录。
The variety list has opened up. Pushu 32, the watermelon-red, once had the field. Now Guangshu, Jishu, Zhanshu, and others share it. Zhanshu 12, bred by the city academy, is fragrant, floury, and sticky, with 81 percent large and medium tubers, and moderate resistance to bacterial wilt. The higher brand Huoshan sweet potato uses a drip of seafood peptide protein. It is on the national list of notable farm products, and on Guangdong brand lists.
从卖鲜薯到做加工From a fresh tuber to a processed one
种得好是第一步，卖得好、效益高才算真本事。
Growing it well is the first step. Selling it, and keeping the value, is the real test.
遂溪的做法是：鲜薯、加工、出口三条腿走路。广东佳淳农业科技有限公司引进世界领先的红薯专用分选与包装设备，采用高温抑芽、快速糖化、光学分选等先进技术。公司还建有大型红薯冷藏保鲜设施，预冷处理能力达300多万吨，冷库贮藏能力达6万立方米。2025年，企业「火山红薯」年销量突破2万吨，销售额达2.5亿元，直接带动当地农户年增收6000多万元。
Suixi walks on three legs: fresh tubers, processing, and export. Guangdong Jiachun brought in sorting and packing built for sweet potato, with heat to hold sprouting, fast sweetening, and optical grading. Its pre-cooling capacity is more than 3 million tonnes and cold storage 60,000 cubic metres. In 2025 Huoshan sweet potato sold more than 20,000 tonnes, RMB 250 million, and added more than RMB 60 million a year to local household income.
深加工领域的拓展同样可圈可点。以优质薯泥为基础原料，遂溪开发出炭烤红薯、火山薯片、火山薯泥冰淇淋、烤薯拿铁、厚芋泥奶茶等市场爆款产品，深受年轻消费者青睐。全县同步建成年加工甘薯30万吨的淀粉厂和2万吨的粉丝加工厂，并正积极推动甘薯预制食品、美容护肤品、饲料、酿酒等多元化发展，构建「藤—薯—渣」全链绿色生产体系。
Processing has its own list: roasted potato, chips, an ice cream and a latte made from the mash, and a thick taro-style tea. The county has a starch plant for 300,000 tonnes a year and a noodle plant for 20,000 tonnes, and it is pushing prepared food, skincare, feed, and wine, on a vine–tuber–residue cycle.
市场拓展方面，遂溪借助电商平台和直播带货持续打开销路。凭借「中国甘薯之乡」「全国绿色食品原料（甘薯）标准化生产基地」「国家现代农业（甘薯）产业园」「全国农业全产业链典型县」四项国字号荣誉，线上年销售额已突破4.6亿元。海外市场同样表现亮眼，2025年湛江海关监管出口红薯货值超1400万元，产品远销加拿大、荷兰及东南亚等国家和地区。
Ecommerce and livestreams keep opening sales. Four national titles — home of Chinese sweet potato, a national green-food raw-material base, a national modern-agriculture park, and a model county for a full farm chain — sit behind online sales above RMB 460 million a year. In 2025 exports supervised by Zhanjiang customs exceeded RMB 14 million, to Canada, the Netherlands, and Southeast Asia.
从种苗繁育、标准化种植到精深加工、电商销售，遂溪甘薯已形成完整产业链条。「遂溪番薯」入选全国名特优新农产品名录，「下六番薯」获评国家地理标志保护产品。曾经填饱肚子的「粗粮」，如今成了千家万户实打实的「致富薯」。
From seedlings and standard planting to processing and online sales, the chain is in place. Suixi sweet potato is on the national list of notable products, and Xialiu sweet potato is a national geographical indication. A grain that once only filled a stomach is now what raises a household.
9月22日至24日，第一届湛江热带农产品促消费活动将在湛江奥体中心举行。甘薯将和菠萝、荔枝、红橙等一起亮相——这颗曾经不起眼的薯，如今已经有底气站在聚光灯下，向全国采购商和消费者展示湛江的产业实力。
From 22 to 24 September the fair was to open at the Olympic centre. Sweet potato was to stand with pineapple, lychee, and red orange — a tuber that once drew no notice, now able to face buyers from across the country.
