A Study on the Selection and Disposition of Several High-Yield Clones from Oil-Camellia

The high-yield clones, No. 7(79-5), 3(Fu 17) and 6(80-24) as well as the fairy high-yield and dwarfish clones, No. 1(79-13) and 6(Fu 19), have been selected by means of the standard identifying experiments and productive investigations on eight clones of Oil-Camellia for ten years in Jinxian County, Jiangxi Province. It is more suitable that the clones, No.7, 3, and 2, were used as major cultivated strains and the clones,No. 1 and 6 as associated cultivated strains, after examining and evaluating synthetically every index about them. The model of the combination disp-osed, which was recommended for production, was No, 7-3-2-7-1-6, which each clone was planted into one row in order of them and in turn of the model. The oil yields of the model per ha and per year from 4-yr-old to 8-yr-old plantation can reach 169.7, 210.0, 290.3, 352.5, and 384.0kg respectively under common management, if bud-understock graftings are adopted to afforest and the spacings of 1.5m×2.0m,3330 plants per ha, are kept.
