摘 要:油松具有耐干旱、抗性强等特点,是我国三北地区主要的造林树种之一。但由于油松无性繁殖的难度较大,因此,生产上多采用营建种子园的方式来繁育良种。本文从种子园的规划设计、营建技术以及营建后的管理等方面总结了油松种子园的营建管理技术。Pinus tabulaeformis has the characteristics of drought resistance and strong resistance,and is one of the main afforestation tree species in the three north regions of China.However,due to the difficulty of clonal propagation of Pinus tabulaeformis,seed orchards are often used in production to breed improved varieties.This paper summarized the construction and management technology of Pinus tabulaeformis seed orchard from the aspects of planning and design,construction technology and management after construction.
