4种地被观赏竹的笋期生长特性比较

对黄条金刚竹、菲白竹、鹅毛竹、铺地竹的发笋、退笋和高生长等生物学特性做了比较,结果表明:4个竹种在发笋和退笋数量上都呈现"少-多-少"的趋势,发笋数:铺地竹＞菲白竹＞鹅毛竹＞黄条金刚竹;退笋数:鹅毛竹＞铺地竹＞菲白竹＞黄条金刚竹;成竹率:菲白竹＞铺地竹＞黄条金刚竹＞鹅毛竹.所有竹种的高生长都呈现"慢-快-慢"的趋势,其生长曲线呈"S"型.高度:黄条金刚竹＞鹅毛竹＞菲白竹＞铺地竹.

Comparasion on the Growth Characteristics of Four Ornamental Bamboo Species

The biological characteristics of bamboo shoot,recessional bamboo shoot and height-growth of Pleioblastus kongosanensis f.aureo-striatus, Pleioblastus fortunei,Shibataea chinensis and Pleioblastus argenteostriatus had been studied in this article. Four bamboo species showed the same law of "less-more-less" on the quantity of bamboo shoot and recessional bamboo shoot.The quantity order of bamboo shoot was Pleioblastus argenteostriatus>Pleioblastus fortunei>Shibataea chinensis>Pleioblastus kongosanensis f.aureo-striatus;The quantity order of recessional bamboo shoot was Pleioblastus shibataea chinensis>Pleioblastus argenteostriatus>Pleioblastus fortunei>Pleioblastus kongosanensis f.aureo-striatus;The order for the rate of growing bamboo shoot was Pleioblastus fortunei>Pleioblastus argenteostriatus>Pleioblastus kongosanensis f.aureo-striatus>Shibataea chinensis.The growing of all the bamboo species showed the condition of "slow-quick-slow"with a growing curve of S shape.The order of height growth was Pleioblastus kongosanensis f.aureo-striatus>Shibataea chinensis>Pleioblastus fortunei>Pleioblastus argenteostriatus.
