摘　　要：应用“正态分布标准差分类法”划分钟萼木苗木不同生长类型并进行造林效果研究。结果表明,钟萼木苗木不同生长类型与杉木行带混交造林后,第一、二年在混交效应不明显的立地生境下,相邻生长类型树高年生长量差异相对较小,相隔一个生长类型以上,高年生长量都表现极显著差异,H6、H7生长类型的高年生长量大,对立地生境适应能力好,平均值及2个标准差以内生长类型是该树种群体生长状况的代表,年高生长量较低。该树种造林后第三年,平均值及2个标准差以内生长类型高年生长量在40~60 cm间,H7生长类型个体年高生长量达2.0 m以上。个体高生长表明,H7生长类型3年生高生长达4.0 m以上,其他生长类型3年生高生长在1.0~3.0 m,研究不同生长类型对造林生境的适应能力,为该树种人工培育与保护提供理论参考。The perennial results of artificial forestation was studied with the different growth-types of seedling of Bretschneidera sinensis Hems L. by“the standard deviation classification method of normal distribution” in this paper. The results indicated that the annual growth difference of height of adjacent growth-type was smaller and the difference of annual growth of height over one growth-type were significant after artificial forestation of B. sinensis Hems L. mixing with Cunninghamia lanceolata using the model of row and band under the condition of non-significant of mixing-effect from 1 to 2 years, The annual growth of height of H6 growth-type and H7 growth-type were high and the adaptive capacity were better for growth environment, these growth-types of average and within 2-standard deviation were regarded as growth representation of the tree that the annual growth of height was lower. The annual growth of height of these growth-types of average and within 2-standard deviation were from 40 cm to 60 cm and the annual growth of height of H7 growth-type was over 200 cm after artificial forestation of three-years. The height growth of individual indicated that height-growth of H7 growth-type of 3-years was over 4.0 meter and the height-growth of another growth-types of 3-years were from 1.0 to 3.0 meter and the study of adaptive capacity of the different growth-type for growth environment will provide the theory reference for artificial forestation and protection..
