马尾松一代无性系种子园营建与丰产技术研究

本研究历经“六五”选优,“七五”建园与“八五”投产,长达工5年之久的科学研究与生产实践,比较系统地阐述了马尾松一代无性系种子园的营建、管理与种子丰产技术。“八五”期间种子园开始生产种子,产量逐年上升,1995年大面积平均每公顷产量为9.375kg,最高小区平均每公顷产量达27.825kg,属于马尾松投产初期高产种子园之列。种子园混系种子质量优异,5年生子代林材积增益比对照大41.4％。种子园的建成与投产,可为速丰林建设提供优质良种。

Study on Establishment and Production Techniques of The First-Generation Clonal seed Orchards of Masson Pine (Pinus massoniana)

Through 15 years research and application, which included Plus-tree selection of masson pine in the 6th 5 - year Plan, seed orchard establishment in the 7th 5 - year Plan and seed production in the 8th 5 - year Plan, resulted a set of techniques for establishment and management of seed orchard and seed production. The orchard began to produce masson pine seeds in the 8th 5 - year Plan. The yield increased year by year with 9.375kg/hm~2 of average yield, 27.825kg/hm~2 of the polt with the highest output in 1995, which matched highyielding Masson pine seed orchard in the initial phase. The quality of mixed family seeds was excellent. The stem volume of 5 - year forest from seed orchad progeny was 41.4% more than the control.
