塔山屯镇“棚”勃发展_我的网站

Long Bamboo, a company based in East China's Fujian Province, developed the technique that preserves the bamboo's tough outer layer and allows different parts with different densities of the material to be used according to their properties, improving its overall performance.
In the past, the outer skin of bamboo was often treated as leftover material and eventually burned into low-value bamboo charcoal.
According to a company release in February, bamboo-based composites now make up more than 25 percent of the entire drone, while its fuselage skin is made entirely from the company's own high-performance bamboo composite material.
The bamboo-based material also offers a major cost advantage, costing only about one-quarter to one-tenth as much as aviation-grade carbon fiber. After the drone is retired, the material can naturally degrade, allowing it to effectively "come from nature and return to nature."
The team spent four years building data models, upgrading equipment and refining the material. The resulting drone has a wingspan of more than 2.5 meters but weighs only about 7 kilograms, and has already completed multiple test flights, according to CCTV News.
Bamboo was traditionally used mainly in products such as tableware and furniture. Now, however, the material is finding its way into a wider range of industrial applications. Bamboo fiber is being used in automobile interiors, while bamboo-based materials are also being explored as possible substitutes for plastics, glass fiber and carbon fiber in some applications.
China has the world's largest bamboo resource base, with about 7.56 million hectares of bamboo forests nationwide. The country also ranks among the world leaders in bamboo resources, bamboo cultivation technologies and the development and utilization of bamboo materials, per CCTV News.

。 《日报》全媒体记者 张宝程 6月4日一大早，刘明与爱人找来帮手，来到自家的大棚内采摘茄子。看着架上果实累累，大伙笑容满面、干劲儿十足。“这种蔬菜既高产，下果期又长，从根部摘到顶部，能挺八九个月，真是种植户的‘摇钱树’。” 作为地道的绥中县塔山屯镇丁家村人，不到40岁的刘明聪明肯干。几年前，看到同村人利用国家好政策、当地政府大力扶持、区位优势的东风建大棚发展设施农业，他也建起了一座长150米、宽10米的钢架高质量大棚。
B | 经过学习，加上他与爱人起早贪黑精心侍弄，大棚里的茄子茁壮成长。 “我家大棚规格较高，设施完备。
C | 管理经营到位的话，一年产值10万余元，去除人工等各种费用，纯利润能达到8万元。
D | 同村有些规格一般的大棚，年纯利润也在6万余元。”刘明说。 塔山屯镇建大棚种植蔬菜有30余年历史，从最初的几座、几十座、几百座，发展到目前2550座。
E | 主要集中在丁家村、潘家村、许家村、西王村等4个村子，涉及1000余户4000多口人。
F | 绥中县农业农村局统计显示，该镇的大棚规模，在绥中县20余个乡镇名列前茅，主要种植茄子、辣椒、西红柿等蔬菜。 据塔山屯镇镇长孙雪介绍，由于蔬菜的质量、价格在市场有较强的竞争力，多远销北京、上海、武汉等城市。
G | 种植户销售大都采用合作社或利用自己的人脉资源及农村经纪人模式。种植户在技术、资金、销售等方面遇到困难，镇政府第一时间予以指导、帮扶。
H | 棚菜经济是塔山屯镇支柱产业，据粗略统计，2023年年产值近3亿元，年利润近2亿元。一直以来，镇政府科学谋划、有效实施、积极引导，朝着农业产业规模化、高质量发展的方向前行。孙雪说，镇政府将给种植户提供最暖心的服务、最细心的沟通、最舒心的环境，让他们心无旁骛专心生产、扩大经营，让塔山屯镇的棚菜经济“棚”勃发展。
