杉木矮化型高产种子园建园技术

Techniques for Establishing the Dwarfed High-yield Seed Orchard of Cunninghamia Lanceolata

为实现杉木种子园丰产稳产的目标,方便种子园球果采摘,笔者经过多年探索形成一套“矮化型果园式”杉木种子园建园技术体系。本文从无性系嫁接苗培育、种子园营建、截顶矮化、刻伤促萌、整形拉枝、抚育管理、辅助授粉等方面详细介绍了该类型种子园建园技术,以期提高种子园产量及品质,为杉木种子园科学经营提供参考。

To achieve the goal of establishing a high-and-stable yield seed orchard of Cunninghamia Lanceolata with convenient harvest of cones,a technical system for establishing the dwarfed high-yield seed orchard of Cunninghamia Lanceolata was developed through years of exploration.In this paper,a detailed introduction was made to the techniques for this type of seed orchard from such aspects as cultivating clone graftings,building a seed orchard,cutting the treetop and dwarfing,making scars to promote sprouting,shaping the branches,tending managing and supplementarily pollinating,so as to improve the yield and quality of the seed orchard and provide reference for scientific management of the seed orchard.
