油茶是我国特有的木本油料树种,遍布南方15个省(区),面积约有6000万亩。但普遍存在的一个问题是管理粗放、产量低。我国林业科研人员为此进行了长期的研究,对油茶良种选育、低产林改造、集约管理、立体种植开展了大量研究工作,已取得可喜的成果,并积累了一些比较成功的经验。江西省林科所和萍乡市林科所协作开展油茶立体栽培研究,于1986年在油茶林下间种药材--草珊瑚,提高油茶林经济效益。在萍乡市7个点计19. 6亩油茶林中间种草珊瑚,采用二节一叶或半叶的草珊瑚短穗扦插(插穗不经药剂处理),平均成
Camellia oleifera is a unique woody oil species in our country, distributed in 15 provinces (districts) in the south with an area of about 60 million mu. However, a common problem is extensive management and low output. Our forestry researchers conducted a long-term research to this end, and carried out a great deal of research work on the breeding of elite seeds of Camellia oleifera, transformation of low-yield forests, intensive management and three-dimensional planting, and achieved gratifying results and accumulated some relatively successful experiences. Forestry Branch of Jiangxi Province and Pingxiang City, Linke Institute collaborative development of three-dimensional cultivation of Camellia oleifera in 1986 in the species of herbs - grass coral, improve the economic benefits Camellia oleifera. In Pingxiang City, seven points, 19.6 acres of Camellia oleifera forest grass coral, with two or one half leaves of the grass coral short cuttings (cuttings without drug treatment), the average
