This 8-year research, promotion and application project selected elite strains of high-oil Melaleuca alternifolia, and carried out systematic research on tissue culture and rapid propagation, cultivation, processing and utilization of these elite strains. Aiming at the key technical bottlenecks in the industrialization of Melaleuca alternifolia, a complete industrialization system was established, covering elite individual selection, tissue culture rapid propagation, efficient cultivation, high-purity 4-terpineol processing and application, and product development. The technology has reliable performance, strong operability and practicability, and has extremely high application value. Innovations have been made in elite individual selection, tissue culture industrialization, supporting efficient cultivation technologies, high-purity 4-terpineol extraction processes and product applications, and the achievements have reached the leading level in domestic similar research. The promotion and application of the achievements have promoted the rapid development of Melaleuca alternifolia planting and deep processing industries. 1. Selection of elite high-oil Melaleuca alternifolia strains: 21 elite strains with high biomass and high oil content were selected. Their essential oil quality indicators (test report: 4-terpineol content 46.0%, 1,8-cineole content 3%) exceed the international "tea tree oil" standard (ISO 4730-2004). The biomass gain of elite strain branches and leaves was 1.83 times, and the oil content gain was 1.29 times, with significant selection gain effect. 2. Tissue culture industrialization technology for high-oil elite strains: A unique medium formula for tissue culture industrialization of high-oil elite strains was developed, and a technical system for tissue culture industrialization of 12 elite strains was established. The problems of browning, yellowing and death of elite strain tissue culture seedlings were solved, and the tissue culture efficiency was improved. The subculture multiplication rate was increased to 5.3, the rooting rate and transplanting survival rate of tissue culture seedlings both reached over 95%, and the high-oil elite traits of tissue culture seedlings did not mutate. 3. Construction of high-oil scion orchard and rapid cutting propagation technology: A technical system for scion orchard construction and tender branch cutting rapid propagation of tissue culture seedlings was proposed, including planting density of elite strain tissue culture seedlings and height of stem cutting for sprouting promotion. The cutting rooting rate was increased from 78% to 97.5%, improving rapid propagation efficiency and reducing seedling cost. 4. Efficient cultivation technology for high-oil elite strains: Through comparative experiments between tissue culture seedlings and cutting seedlings of high-oil strains, an efficient cultivation and supporting technical model was proposed, including optimal planting density, fertilization measures, harvesting time and harvesting method for tissue culture seedlings. The average branch and leaf yield reached 3.0 tons/mu·year, and a 1050-mu demonstration base for high-yield and efficient cultivation of tissue culture seedlings was established. 5. One-step high-yield extraction of high-purity 4-terpineol and processing utilization: Using special rectification equipment and equipment passivation technology, through processes such as acid removal and addition of retention agents, the "tea tree oil" extraction and processing technology was optimized, improving the yield and quality of essential oil. The one-step extraction rate of 4-terpineol reached 85%, the total extraction rate was 96%, and the purity reached 99.7%, exceeding export standards and Fujian Provincial local standards. Taking high-purity 4-terpineol as the main raw material, 16 new products including pollution-free natural herbicides, fungistatic creams and other medicinal, daily chemical and biopharmaceutical products were developed. 6. Authorized patents, standard formulation and published papers: 5 national invention patents and 4 design patents were authorized. 1 Fujian Provincial local standard "4-terpineol (tea tree oil type)" and 2 new product enterprise standards were formulated, and 7 academic papers were published.
