三台县国家柏木良种基地种子园经营管理实践
|
摘要
种子园是获得林木良种的重要基地。文中简述三台县国家柏木良种基地建设情况,对经营管理中存在的缺少经费、经营停滞不前,按生产营林模式建设、种子产量低,以"表型"性状显著的优树作为建园遗传材料,未开展遗传测定等问题进行分析;对种子园实施土壤管理、病虫害防治、留优去劣疏伐、树体管理和升级换代等集约化精细化经营管理措施效果进行总结。提出对种子园进行升级换代,加强种子调剂,完善储备制度等建议。
Seed orchard is an important base to obtain improved tree species. This paper briefly described the construction of national fine-varieties base of Cupressus funebris in Santai County, and analyzed the problems in the operation and management such as insufficient fund, stagnant operation, construction with mode of production and forest management, low seed yield, using excellent "phenotypic" trees as genetic materials, and not carrying out genetic determination. Based on the summary for the effects of intensive and fine management measures such as soil management, pest control, thinning, tree management and upgrading, some suggestions were put forward including upgrading seed orchard, strengthening seed regulation and perfecting reserve system.
