摘　　要：在福建省明溪县胡坊镇胡坊村开展不同施肥处理(尿素、复合肥、过磷酸钙)和不施肥(CK)对方竹出笋退笋规律的研究。结果表明:施肥处理的方竹出笋数量是不施肥的3倍以上,其中施用尿素的方竹出笋数最多、出笋分布平稳,但后期退笋率高;施用复合肥的方竹出笋数量次之,出笋盛期的出笋率约70%,退笋数也以盛期为高;施用过磷酸钙的方竹出笋数量最少,出笋分布相对平缓,出笋盛期和出笋末期的退笋数量差异不大。不同施肥处理的方竹在出笋期内的退笋总数大致相同。The effects of different fertilizer treatments(urea, compound fertilizer, superphosphate) and no fertilization(CK)on the rules of bamboo shoots emergence and degeneration of Chimonobambusa quadrangularis were carried out. The results showed that the number of bamboo shoot emergence of C. qundrangularis treated with fertilizer was more than three times that of non-fertilization treatment, in which the number of bamboo shoot emergence of C. qundrangularis applied with urea was the most, and the distribution of bamboo shoots emergence was stable, but the rate of bamboo shoot degeneration was high in the later stage. The number of bamboo shoot of C. qundrangularis applied with compound fertilizer was the second, and the bamboo shoot emergence rate is about 70% in the prosperous period while the shoot degeneration was also high. The number of bamboo shoot with the application of superphosphate was the third, and the distribution of bamboo shoots was relatively smooth, and the number of bamboo shoots degeneration was no significant difference between the peak and the end of bamboo shoots. The total number of bamboo shoots degeneration among different fertilization treatments was approximately the same during the shoot emergence period.
