关于我国野生观赏树木资源选育、繁殖和培育的思考

Thoughts on Selection Breeding,Propagation and Cultivation of Wild Ornamental Tree Species in China

我国野生观赏树木资源种类丰富、分布广泛、开发利用潜力巨大。近年来针对野生观赏树木资源现状的调查研究逐渐增多,说明人们已经充分注意到乡土观赏树木资源开发和保护的重要性。目前除了少数几个传统树种外,大部分乡土观赏树种都处于原种简单利用水平,没有选育形成丰富多彩的观赏品种体系。建议在注意保护野生种质资源的前提下,开展全民选育活动,大力选择和培育特色优良观赏树木品系,同时拓宽观赏树木的视野,加强原来只是作为用材树种来培育的树种的观赏品系开发。野生观赏树木繁殖和培育技术虽然取得了一定的成绩,但是在繁殖生物学、栽培生态学、栽培理念和栽培技术体系等方面均存在很大的问题,建议学习和应用国外先进理念与技术,大力加强相关研究。

The wild ornamental trees resources are abundant and widely distributed in China with huge application po- tential Recently, the investigations on the resources of wide ornamental tree species have been on the gradual rise, which indicates that that full attention has been put on the importance to develop and protect native ornamental tree re- sources. Except of a few conventional species, most of the native ornamental tree species are now utilized at a simple level, and selected and improved ornamental lines failed to take form. It is advised to engage all walks of life in the ornamental line selection and breeding from wild tree species on the condition of well protecting the wild germplasm resources, and facilitate the development of ornamental lines of species that used to be cultivated as timber species by broadening the range of ornamental trees. Certain achievements have been made in propagation and cultivation of or- namental lines from wild ornamental species, but there are many problems in propagation biology, cultivation ecology, cultivation concept and technology. It is suggested to learn and apply advanced concept and technologies developed in other countries, and strengthen relevant research.
