Growth behavior of Phyllostachys nigra var. henonis （Bambusoideae） in Central China

在华中的 Shennongjia 国家自然保护区，竹子上的母鸡的营养生长行为(Phyllostachys nigra var。henonis (米特福德) Stapf。前 Rendle ) 从射击招募被学习到灰煤杆建立。在 5 月，从地面出现的竹子射击完成了 2.7 射击 m~ 的平均密度(-2) 在 16 天的发芽阶段期间。然而，大约 32% 新射击回来在成熟前死了。虫害，凋谢的死亡和 rodentpredation 分别地为 57% 全部的射击死亡， 29% 和 14% 负责。从 Mayto 6 月，射击达到了 400 ± 23 厘米在 34 天的高度生长阶段期间，与一个奶妈从 1 ～ 56 厘米的竖琴似的变化。在从 6 月散布阶段到 8 月的分支期间展开的所有分支和叶子。射击生产是断然与承受灰煤杆的密度有关，但是否定地到植物层的范围和高度。

In the Shennongjia National Nature Reserve of Central China, the vegetative growth behavior of henon bamboo （Phyllostachys nigra var. henonis （Mitford） Stapf. ex Rendle） was studied from shoot recruitment to culm establishment. In May, bamboo shoots emerg- ing from the ground achieved an average density of 2.7 shoots m^-2 during the sprouting phase of 16 days. However, about 32% of the new shoots died back before maturity. Insect damage, withering death and rodent predation were responsible for 57%, 29 % and 14% of the total shoot mortality, respectively. From May to June, the shoots attained 400 ± 23 cm during the height growth phase of 34 days, with a daily rate varying from 1 to 56 cm. All branches and leaves unfolded during the branch spreading phase from June to August. Shoot production was positively related to the density of standing culms, but negatively to both coverage and height of herb layers.
