摘要
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。
A series of tests was conducted for five years to go further into the technology of raising per unit yield and improving seed quality in Zhejiang Chinese fir seed orchards. Investigations were conducted in these primary seed orchards on its management and adminstration level,and its year yield variation.And the biological and environmental factors were also monitored and collected systematically that would influence the production of Chinese fir seed orchards. The high seed yield technology was thus formed based on above mentioned work. The paper reaveled that the tree parents selection and dispose,and the site selection were the base for high seed yield and superior quality in Chinese fir seed orchard,that the cultivation of stock plants and artificial supplementary pollination were the key factors,and that the fertilization,tree density management,control of insect and disease etc. were the promise of seed production.
