4种观赏地被竹的生长及扩展能力比较
|
摘要
对山东东平县第二苗圃4种3年生地被竹生长进行了调查,并探讨和比较了其扩展能力差异。结果表明:4种观赏地被竹高生长排序为菲白竹>黄条金刚竹>铺地竹>鹅毛竹,地径生长的排序为鹅毛竹>铺地竹>菲白竹>黄条金刚竹,菲白竹与黄条金刚竹的高径比较大,鹅毛竹与铺地竹的高径比相对较小;单位面积株数的排序是菲白竹>铺地竹>鹅毛竹>黄条金刚竹,菲白竹和铺地竹生长较为密集,鹅毛竹和黄条金刚竹相对稀疏; 4种地被观赏竹扩展距离从大到小的排序为鹅毛竹>黄条金刚竹>铺地竹>菲白竹;不同竹种之间相遇时竞争能力不同,其排序为鹅毛竹>菲白竹>黄条金刚竹>铺地竹。
Four dwarf 3-year-old ornamental bamboo species in No. 2 Nursery of Dongping County were investigated and studied for their growth,and their differences in the expansion ability were discussed and compared. The results showed that their heights were different, which were ordered by Pleioblastus fortunei > P. kongosanensis f.aureostriaus > P. argenteostriatus > Shibataea chinensis. Their ground diameter was ordered as Sh. chinensis > P.argenteostriatus > P. fortunei > P. kongosanensis f. aureostriaus. P. fortunei and P. kongosanensis f. aureostriaus had the relatively higher ratio of height to diameter,while the ratio of S. chinensis and P. argenteostriatus was relatively lower. The per-unit densities was ordered by P. fortunei > P. argenteostriatus > S. chinensis > P.kongosanensis f. aureostriaus. P. fortunei and P. argenteostriatus grew relatively denser,while Sh. chinensis and P.kongosanensis f. aureostriaus grew relatively sparse. The extension distance of these dwarf ornamental bamboos was sequenced by Sh. chinensis > P. kongosanensis f. aureostriaus > P. argenteostriatus > P. fortune. They also had different competitiveness when growing together,with the sequence as Sh. chinensis> P. fortunei > P. kongosanensis f. aureostriaus > P. argenteostriatus.
