摘　　要：在田间和温室控制条件下,调查温度、水分和光照对小佛肚竹出笋、成竹和畸形秆率的影响。结果表明,在适宜出笋长竹的温度下,温度对丛出笋数、丛新竹数、新竹畸形秆率无影响,始出笋时间随温度的增高而提前,出笋期相对延长。水分对始出笋时间和出笋期有明显影响,丛出笋数、丛新竹数随水分供应间隔期缩短而递增,新竹畸形秆率随水分供应间隔期缩短而明显下降。始出笋时间、丛出笋数、丛新竹数、新竹畸形秆率随光照强度增大而提前或提高,而光照对出笋期无明显影响。研究说明水分、光照是影响小佛肚竹出笋成竹和畸形秆率的主要环境因素。Under the conditions of field and greenhouse, the influence of temperature, water supply and illumination on shooting, growth and abnormal culm rate was investigated. The results showed that temperature had no influence on shooting number per cluster, new culm number per cluster and abnormal culm rate under adaptive temperature. With the increase of temperature, shooting time was brought forward and shooting period was extended. Water supply had obvious influence on shooting time and shooting period. Shooting number per cluster and new culm number per cluster were increased with the water supply interval shortened, while abnormal culm rate was decreased obviously. Shooting time was brought forward, and shooting number per cluster, new culm number per cluster and abnormal culm rate were increased along with the increase of illumination, while no influence was found for illumination on shooting period. It is concluded that water supply and illumination were the principal environmental factors for shooting, growth and abnormal culm rate of Bambusa ventricosa.
