以提高云杉种子园良种产量及分类经营满足当前社会对云杉(Picea asperata Mast.)良种的需求、实现云杉种质资源遗传多样性的保存。通过3年的调查研究表明:去劣疏伐、土壤管理及树体管理是云杉种子园的促进良种产量的重要措施、分类经营可以提高森林生产经营收益、节约种质保存成本、促进云杉遗传多样性的保存。
In order to improve the seed production and classification of spruce seed orchard management to meet the current social needs of the good seed of Picea asperata Mast., To achieve conservation of genetic diversity of spruce germplasm resources. Through 3 years of investigation and study, it is shown that removing poor thinning, soil management and tree management are important measures to promote seed yield of spruce seed orchard. Classified management can improve the income of forest production and management, save germplasm conservation cost and promote spruce Conservation of genetic diversity.
