种子园能提供遗传品质得到一定程度改良的种子。据子代测定结果表明,现阶段杉木种子园遗传增益达15%左右。目前人们已认识到采用种子园良种,是促进杉木速生丰产重要措施。因此,促进种子生产达到高产、稳定是当前杉木种子园经营管理急待解决的问题。本场为我省林木良种繁育重点基地之一。 Seed orchards can provide seeds of improved genetic quality to some extent. Progeny results show that the current stage of Chinese fir seed genetic gain of about 15%. At present, people have realized that the use of seed orchard seed is an important measure to promote fast-growing Chinese fir. Therefore, to promote seed production to achieve high yield and stability is currently the urgent need for the management of Chinese fir seed orchard.
