摘要
[目的]进一步研究日本柳杉的生长与土体的关系,为其合理布局提供依据。[方法]选择贵州黔中地区石英砂岩、煤系砂页岩、紫色砂岩、第四纪粘土、灰质白云岩及变质砂岩栽种日本柳杉,观察其在不同岩性土体上的生长情况。[结果]日本柳杉的保存率在石英砂岩和煤系砂页岩上较高,在第四纪粘土上最低。不同岩性土体对日本柳杉的树高生长有一定的影响,随着年限的增加,影响越来越小。不同岩性土体对地径生长在生长早期存在显著差异(P<0.05),随着年限的增加,差异逐渐减小。不同岩性土体对日本柳杉的胸径生长没有产生显著差异。[结论]不同岩性土体上栽种的日本柳杉反映出不同的适应性和生长效应。
[Objective] The research aimed to further study the correlation between the growth of Cryptomeriajaponica and soil and provide basis for its reasonable distribution. [Method] The quartz sandstone, coal measure arenaeeous shale, purple sandstone, the quaternary clay, calcite dolomite and metamorphic sandstone in middle Guizhou were selected to plant C. japonica so as to observe its growth conditions in soils from different rocks, [Result] The preservation rate of C, japonica on quartz sandstone and coal measure arenaceous shale was higher, while that on the quaternary clay was lowest. Soils from different rocks had certain effects on the tree height growth of C, japonica and the effects became smaller and smaller with the increasing of the growing years. The effects of soil from different rocks on the ground diameter growth of C. japonica had significant difference in early growth stage（P〈0.05） and the difference gradually decreased with the increasing of the growing years. The effects of soils from different rocks on the growth of diameter at breast height in C. japonica had no significant difference. [Conclusion] The C. japonica planted in soils from different rocks reflected different adaptability and growth effects.
