Tech-driven sugarcane farming boosts yields, cuts costs in Guangxi_我的网站

一 |       香港8月14日电（黄茜恬）由国家行政学院香港同学会、香港特区政府公务人员联会、中国国家行政学院（香港）工商专业同学会及香港经济智库联合主办的香港特区立法会议员北京研修心得分享会14日在香港举行。  据介绍，7月19日至25日，特区立法会全体议员赴京展开为期一周的国家事务研修考察。    (ECNS) -- At the "Sweet Light" modern sugarcane industrial park in Quli Town, Fusui County, in Chongzuo, south China's Guangxi Zhuang Autonomous Region, sugarcane varieties including Guitang 44, Yunzhe 081609, Guitang 76, Zhongtang 3, and Zhongfu 1 are thriving, with most stalks standing more than three meters tall.    The park rotates several varieties and plants them in separate zones to keep yields stable and the fields ecologically resilient.        Yang Xue, who has worked in the sugarcane industry for eight years and now runs an agritech company, has watched the shift from farming by experience to farming by data. Virus-free seedlings and the cultivation methods that go with them can extend ratoon cropping from three years to about five, he said, with germination rates reaching 95%. "In Chongzuo, per-hectare sugarcane yield used to be around 60 metric tonnes. With new varieties, improved cultivation methods, and planting models, yields have now risen to 72 metric tonnes," he said.    To manage the park's 333 hectares of contiguous fields, Yang's team has installed a smart irrigation system that combines water, fertilizer, and pesticide application. It can be run from a computer or a mobile app, with irrigation timing, flow, and volume set precisely. One worker can now cover more than 67 hectares.    The system has since been upgraded to a dual-pipe design, Yang said, allowing water, fertilizer, and pesticides to be applied together and accurately. Annual electricity costs have fallen from 1,200 yuan (about $168) per hectare to 750 yuan (about $105). Four workers can now fertilize 40 hectares in a day, work that previously took 30 workers to cover less than seven hectares.        Mechanized harvesting has cut costs as well. Cutting and loading by hand costs more than 16,500 yuan per hectare, based on a yield of 105 metric tons per hectare and a rate of 160 yuan per metric ton. With machine harvesting, farmers receive a state subsidy of about 3,000 yuan per hectare and pay only 750 to 1,200 yuan for the service. The park also returns chopped stalks to the fields, saving another 450 to 600 yuan per hectare in fertilizer.    The Chinese Academy of Tropical Agricultural Sciences (CATAS) has been working with the Guangxi Academy of Agricultural Sciences and other institutions on variety improvement, seedling propagation, pest control, green cultivation, and mechanical harvesting.    Wu Qibin, a researcher at the Sugarcane Research Center of CATAS's Institute of Tropical Bioscience and Biotechnology, said Guangxi is China's core sugarcane-producing region, with more than 800,000 hectares under cultivation and over 60% of national sugar output. The industry is now pursuing two main goals, he said: breeding high-quality varieties suited to machine harvesting, and developing specialized machinery matched to those varieties.    (By Tang Yuxian)                    。这是香港回归祖国以来，特区立法会全体议员首次赴京参加此类研修考察活动。研修内容涵盖国家安全、国际关系、国家“十五五”规划、基层治理等重大课题，并实地走访新质生产力、人工智能等前沿领域。  香港特区政府公务人员联会副主席赖震晖在分享会上致辞时表示，议员们以开放的胸怀、求知的热忱，走进国家治理的核心课堂，深入了解国家发展大局。研修成果的价值在于分享、转化与应用，希望通过议员们的亲身讲述，让更多市民感受到国家发展的最新脉搏。  港区全国人大代表、特区立法会议员陈振英分享时说，本次研修所积累的知识与视野，将成为他日后履职的行动指南。香港的首个五年规划应优先纳入本地核心优势产业，以及让市民有获得感的政策措施。  香港工会联合会会长、特区立法会议员吴秋北分享时表示，国家“十五五”规划是一个有机整体，香港必须读懂背后的战略意图，找准定位，将独特优势转化为发展动能。  特区立法会议员陈祖光说，香港要全面对标国家“十五五”规划，在科技创新、金融国际化和制度型开放等领域积极作为，发挥“超级联系人”作用。  特区立法会议员陈宗彝表示，香港应以“南金融、北创科”为双引擎，把握国家“十五五”机遇，以香港所长服务国家所需。
