潮州茶园“生态加减法”：“茶草共生”模式激活茶产业绿色转型新路径

Core Viewpoint - The article discusses the "tea-grass symbiosis" model in Chaozhou, which promotes the green transformation of the tea industry by integrating the cultivation of broad-leaved moneywort with tea plants, leading to ecological and economic benefits for farmers [3][4][26]. Group 1: Ecological Benefits - The "tea-grass symbiosis" model addresses the issue of weed control in tea gardens, creating a win-win situation for ecological enhancement and farmer income [3][4]. - The broad-leaved moneywort can suppress weeds by up to 80%, reducing the reliance on chemical herbicides [11][12]. - The root nodules of broad-leaved moneywort can provide nitrogen equivalent to an annual application of 15% nitrogen fertilizer per acre, while also increasing soil organic matter by 5% annually [14]. Group 2: Economic Benefits - Farmers can save approximately 800 yuan per acre on weed control costs and 300 yuan per acre on soil loosening due to the presence of broad-leaved moneywort [20]. - The use of broad-leaved moneywort leads to a 20% reduction in chemical fertilizer usage, improving the quality of tea leaves [22][23]. - The model has resulted in increased tea quality, with award-winning tea produced from gardens using this method [23]. Group 3: Implementation and Expansion - As of August 2025, the area under the "tea-grass symbiosis" model has reached 4,941 acres, covering 14 tea-producing towns [5]. - The goal is to expand the model to over 6,000 acres by 2025, with interest from other tea-producing provinces such as Fujian, Sichuan, and Yunnan [31][28]. - The model is seen as a replicable ecological solution for green transformation in southern hilly tea regions [26].
