摘　　要：以粽巴箬竹、髯毛箬竹和美丽箬竹为研究对象,调查分析其高生长和发笋规律,探讨土壤温湿度对高生长的影响,旨在为箬竹栽培、经营提供理论参考。结果表明:3种箬竹的萌发生长期大约在3月上旬至6月中旬,一般需80~90 d完成高生长;3种箬竹的高生长均呈“慢-快-慢”的变化趋势,高度日生长量呈波动性变化,约在出土后20 d左右开始迅速增加,在出土41 d左右达到峰值,在出土81 d后基本稳定;土壤温湿度日变化不是影响箬竹幼竹高生长的主要环境因子。研究结果揭示了三种箬竹幼竹的萌发生长规律,为箬竹丰产经营提供了参考。The rhythm of height growth and shoot germination of Indocalamus herklotsii,I.barbatus,and I.decorus were investigated and analyzed,and the effect of soil temperature and humidity to height growth was discussed in the study,in order to provide theoretical reference for the cultivation and management of Indocalamus species.The results showed that the germination period of the three kinds of Indocalamus was from early March to mid-June,and the high growth was generally completed in 80 to 90 days.The height growth of the three species Indocalamus showed a slow-fast-slow change trend,and the daily height growth showed a fluctuating change.They began to grow rapidly about 20 days after the excavation,and the daily growth reached its peak on the 41~(st) day after the excavation,and the high growth was basically stable after 81 days.At the same time,the study found that the change of daily temperature and humidity in soil were not the main environmental factors affecting the growth of bamboo larvae.The study carried out the germination and growth rhythm of juvenile individuals of three Indocalamus species and provided references for the high-yield management of Indocalamus.
