摘　　要：通过对寿竹出笋和幼竹高生长阶段的调查,研究了寿竹笋期的生长发育规律。结果表明,寿竹出笋从5月初开始,出笋盛期为5月8日到5月21日,盛期出笋数量占84.7%,出笋全部持续时间约30天。寿竹的高生长持续60天左右,高生长符合Logistic模型。引起寿竹退笋的主要原因是虫害,占退笋的比例74.7%,造成退笋的主要害虫是竹笋泉蝇。该地区寿竹整个出笋期平均成竹率仅为11.7%。Rules of shooting and height growth of Phyllostachys bambusoides f. shouzhu Yi were studied. The results showed that the shooting period was from May 6 to June 4. The period lasts 30days. The peak of shooting period was from May 8 to May 21 and the amount of shooting was accounted for 84.7%. Height growth of the bamboo was about 60 days and could be fitted with the Logistic curve. The shoot degradation of 74.7% was resulted from the Pegomyia phyUostachys Fan. The average culm rate of bamboo shoot was only 11.7% in this areas.
