五年中布置了多项试验，对浙江省杉木投产种子园丰产经营技术作出了进一步的研究；调查了浙江几个主要杉木一代种子园的经营管理水平及年度产量变化情况；进行了影响杉木种子园种子产量的生物因子和环境因子的系统监测和收集。在此基础上总结出杉木种子园丰产技术系列。认为建园亲本材料的选择和配置、园址的选定是种子园优质高产的基础；提高母树正冠率等树体管理、人工辅助授粉是关键；科学施肥、密度管理、病虫害防治等配套经营管理措施是种子园种子稳产高产的保证。
In the past five years, a series of experiments were arranged to further study the high yield management techniques of Chinese fir seed production in Zhejiang Province. The management level and annual output changes of several major Chinese fir seed orchards in Zhejiang Province were investigated. Systematic monitoring and collection of biological factors and environmental factors of seed yield in the park. On this basis, summed up the fir seed orchard high yield technology series. It is considered that the selection and configuration of parental materials for park construction and the selection of park sites are the basis for the high quality and high yield of seed orchard; the management of tree body such as the improvement of the parent tree’s canopy crown rate and artificial pollination is the key; and supporting management of scientific fertilization, density management, pest and disease control Management measures are seed orchard seed yield guarantee.
