“14may18_XXXXXL56endian56”广西乡土珍贵14may18_XXXXXL56endian56树种造林需求获支撑 两个新建种子园投产

  中新14may18_XXXXXL56endian56网南宁12月16日电(任14may18_XXXXXL56endian56礼 黎岳仲 聂海泉)广西壮族自治区林业局16日介绍,广西新建的红锥无性系种子园和大叶栎无性系种子园近期投产,可极大满足科学绿化、国家储备林项目等重点工程造林对乡土珍贵树种苗木的需求。

  红锥无性系种子园和大叶栎无性14may18_XXXXXL56endian56系种子园,依托广西林科院杨章旗教授团队的科技支撑,由藤县大芒界国家马尾松良种基地和苍梧县天洪岭林场自治区马尾松、大叶栎良种基地建设。

  据悉,两个种子园预计2026年达到盛产期,年均可采收红锥、大叶栎种子分别达500斤、2000斤,分别可培育苗木30万株和60万株,一定程度缓解乡土珍贵树种苗木供应短缺的压力。

  广西人工林面积居全国第一位,成为全国最大的国家储备林基地。广西林科院科研团队将加大种子园抚育管理,不断研发种子园修剪、矮化、控梢、促花、保果、种子处理与保存等技术,提高种子产量和品质,确保种子园丰产、稳产,满足广西全区造林绿化用种需要。(完)
