摘要
从出笋、退笋、高生长规律3个方面对黄条金刚竹的生长发育规律进行了系统的观察,结果表明:黄条金刚竹的出笋历期31d左右,在出笋后第8~9d进入出笋高峰期,约占出笋总数的76.8%;退笋期主要集中在初期和末期;在前期-盛期-末期出笋所长成的竹子,其胸径和竹高均呈下降趋势;幼竹高生长呈“S”形曲线,整个过程表现出“慢-快-慢”的特点,Logistic回归方程能较好的模拟黄条金刚竹的生长过程。
Observation was implemented on the growth regularities such as shooting, degrading and height growth of Pleioblastus kongosanensis f. aureostriatus. The result showed that the shooting period was approximately 31 days, and high peak yield was 8-9 days after the start, which occupied about 76.8% of the total shoot yield. Degrading shoot occurred at the earlier and terminal shooting period. Earlier shoot had higher D.B.H. and height of bamboo. Young bamboo height growth showed Logistic equation "S", with the characteristic of "slow-fast-slow". The Logistic equation could simulated the growth ofP. kongosanensis f aureostriatus.
