摘　　要：对扒晒和施肥因素影响下的绿竹出笋规律进行了研究,结果发现:扒晒能使竹丛提前9 d出笋,并提前半个月左右进入出笋高峰期,同时它对笋目萌发数量的增加也具一定作用,单纯扒晒处理笋目萌发数量比对照增加将近1倍;扒晒和施肥对提早出笋、延长笋期及出笋高峰期,提高笋产量具有协同促进作用,扒晒施肥样地笋期最长,笋产量达98.76 kg/100m2;单因素作用条件下,施肥比扒晒对笋产量的影响要大,是提高笋产量的必要措施,同时施肥能够维持或增加新竹胸径,对新竹成竹质量具有重要作用。Shooting of Dendrocalamopsis oldhmni affected by sunning root-ball and fertilization has been studied. The results showed that the shooting time of sunning root-ball clumps was 9 clays earlier than the non-sunning root-ball clumps; that shooting peak came half a month in advance, and shoots quantity was also in creased. The shoots number of sunning root-ball clumps was increased by one times in contrast with that of the controlled. Sunning root-ball and fertilization had synergistic effects on shooting early, prolonging shooting time, improving shoots yield and so on. The shooting time of sunning root-ball and fertilization plot was longest, and its shoots yield was about 98. 76 kg/100m^2. Under the effect of single factor on shoots yield, the influence of fertilization was greater than that of sunning root-ball, and it was the necessary step for improving shoots yield. Meanwhile, fertilization could keep or increase the DBH （diameter at breast height） of new bamboos, and it was very important to new bamboos quality.
