以攸县、资兴、靖州、江华杉木种子园为主要研究对象，对长期积累的无性系开花结实监测资料进行系统研究。结果表明，不同年份、不同园地、园内不同小气候，不同种源、不同无性系花期和结实差异显著，光照、水肥条件是影响种子园结实的主导环境因子。该研究对指导湖南省杉木种子园的建设具有现实意义。 Taking Youxian, Zixing, Jingzhou and Jianghua Fir Seed Orchards as the main research objects, the long-term accumulation of clonal flowering and fruiting monitoring data was systematically studied. The results showed that there were significant differences in florescence and seed setting in different years, different fields, different microclimates, different provenances and different clones in different years. The light, water and fertilizer conditions were the dominant environmental factors affecting the seed orchard growth. This research has practical significance to guide the construction of Chinese fir seed orchard in Hunan.
