摘要
本文对光箨篌竹笋期的出笋规律、成竹规律以及竹笋的生长发育规律进行了研究。初步认为,光箨篌竹林分的母竹立竹度一般应保持在2500株/亩左右、Ⅰ～Ⅱ级母竹株数保持在40％以上时,才能保证林分的优质高产与稳产;抽枝成竹历期长短受竹笋笋级大小、出土早晚或立地环境条件的影响可相应延长或推迟2～4d左右,一般历时25d,竹笋开始抽枝成竹时的高度一般为5m左右;竹笋在生长发育高峰期明显受到气候因子的影响,尤其是对气温更为敏感。
Study on laws of shooting, bamboo setting and growth of shoot of Phyllostachys nidularia indicated that standing mother bamboo should be kept about 2500 culm/mu, mother bamboo of Ⅰ and Ⅱ class should be kept 40%. Bamboo setting from shooting endured generally 25 days, prolonged 2～4 days by the influence of shoot size, emergency time and site condition. The height of shoot which began branch sprout was about 5m, the peak of growth and development of shoot influenced evidently by climate, especilly temperature.
