速生丰产林培育理论与技术探讨

Discussion on theory and technology of cultivation of fast-growing and high-yield plantation in China

探讨了速生丰产林的界定与内涵;浅析了速生丰产林定向、速生、丰产、优质、稳定、高效6大培育目标的指示性意义;提出我国速生丰产林培育技术途径可主要体现为5大控制、3大管理,即遗传控制、苗木质量控制、立地控制、密度控制、轮伐期控制与植被管理、水肥管理、目标树管理。

The definition and implication of fast-growing and high-yield plantation was discussed. The specific meanings of six cultivation targets of fast-growing and high-yield plantation in China, including directive, fast- growing, high-yield, high-quality, stable and high-efficiency, were analyzed. It was directed that the cultivation technology ways of fast-growing and high-yield plantation in China could be embodied in five control technologies and three management technologies. The five control technologies mean genetic control, seedling-quality control, site control, density control and rotation control. The three management technologies mean vegetation management, water and fertilizer management and target tree management.
