广西香花油茶：“花果同枝”孕育产业新篇

Core Viewpoint - The Guangxi oil tea industry is experiencing significant growth, driven by innovative research and development, with a focus on high-quality varieties and sustainable practices [1][2]. Group 1: Industry Development - Guangxi is a major oil tea production area in China, implementing the "Double Thousand" plan to promote high-quality development in the oil tea industry [1]. - In 2024, the total production of fresh oil tea fruit in Guangxi is expected to reach 2.753 million tons, with tea oil production at 176,400 tons, both showing significant year-on-year growth [1]. - The area under oil tea cultivation in Guangxi has surpassed 10.5 million acres, with a comprehensive output value of approximately 63 billion yuan, benefiting over 1.5 million farmers [4]. Group 2: Research and Innovation - Since 2005, Guangxi Academy of Forestry has collaborated with various institutions to develop new oil tea varieties, significantly enriching local genetic resources [2]. - The "Xianghua" oil tea variety, developed in Guangxi, exhibits strong resistance, fast growth, high oil content, and stable yields, with an average oil content of 10%, which is 3%-5% higher than ordinary varieties [1][2]. - The "Y" series and "An" series of oil tea varieties have been created to enhance fruit size and yield, with the latter expected to expand suitable planting areas northward [2]. Group 3: Technological Advancements - The "high grafting" technique using "Xianghua" oil tea as a scion has shown effectiveness, with yields reaching 300 kg per acre by the third year after grafting [4]. - A portable small vibrating harvester developed by Guangxi University of Science and Technology and Guangxi Academy of Forestry has achieved a 95% fruit harvesting rate for certain varieties, reducing costs and increasing efficiency [4]. Group 4: Economic Impact - The oil tea industry has significantly increased farmers' incomes, with one couple managing 79 acres of oil tea trees earning 306,300 yuan from tea seed sales in 2021 [4]. - The high content of beneficial components like squalene in "Xianghua" oil tea has led local companies to develop skincare and cosmetic products, further enhancing the industry's value [4].
