摘要: [目的]为了加快紫色土工程侵蚀区的植被恢复,针对紫色土工程侵蚀区种植福建柏进行防治侵蚀技术措施和初植密度试验研究。[方法]试验采用裂区试验设计。[结果]试验结果表明:采取鱼鳞坑整地或等高线反坡整地,筑建土石坝,使用土壤稳定剂和铺放秸秆能够提高福建柏造林成活率及其生长量,以铺放秸秆效果更好。不同初植密度对福建柏林分生长状况有影响,考虑到造林成本和调整林分结构,认为株行距1.8m×1.8m,初植密度3086株/hm2更为合理。[结论]该试验总结了一套紫色土工程侵蚀区栽植福建柏的技术措施,在生态层面和森林培育层面都具有重要的意义。

Abstract: To speed up the vegetation restoration in the purplish soil engineering erosion area, the author adopted the split-plot design, and carried out an experiment on erosion preventing measures for cultivating Fokienia hodginsii in the purplish soil engineering erosion area and a study on the initial planting density. The results showed that: adopting fish-scale pit preparation or contour reverse slope soil preparation to construct the earth-rockfill dam, using soil stabilizers and laying straws could improve the afforestation survival rate and the growth of Fokienia hodginsii, in which laying straws was most effective; different initial planting densities affected the stand growth status of Fokienia hodginsii, considering the afforestation costs and the adjustment of stand structure, it was more reasonable when the planting spacing was 1.8 m×1.8 m, and the initial planting density was 3086 plants/hm2. The experiment summarizes a set of technical measures for planting Fokienia hodginsii in the purplish soil engineering erosion area, and has certain significance on ecological level or forest cultivation level.
