摘要
观察了大径紫竹、一年紫、二年紫和三年紫等4种紫竹(Phyllostachys nigra)栽培类型的出笋和成竹过程,比较了它们的出笋和高生长规律。结果表明:紫竹4种栽培类型笋期为20～30天,其中大径紫竹出笋最早;高生长曲线基本为S形,高生长量与温度呈极显著相关。
Shooting and growth of four cultivars of Phyllostachys nigra （large-diameter,one-year-old,two-year-old and three-year-old Ph. nigra） were observed to compare their shooting and height growth rhythm. The results showed that the shoot periods of four cultivars ranged from 20 to 30 days,while the large-diameter Ph. nigra shoot earlier than the other cultivars. The height growth of four cultivars followed the Sigmoid Curve,and the height growth volume was significantly correlated with air temperature.
