【目的】揭示覆盖栽培竹林生理生态变化机制，为现代竹林定向培育和衰退竹林生态修复技术研究提供依据。【方法】采用对比设计和相关性分析，研究覆盖0年（对照）、1年、3年、6年、9年、12年雷竹林出笋规律及其与温度的相关性。【结果】各竹林以覆盖1年竹林出笋最早，笋期最长，笋产量最高，达16633．93 kg／hm2；覆盖3年、6年、9年、12年竹林笋产量分别为：15422．97、12004．90、11652．36和10288．25 kg／hm2；对照竹林出笋最晚，笋期最短，笋产量仅8173．60 kg／hm2；各竹林出笋与气温相关性均未达到显著水平，但对照竹林与气温相关性最高，相关系数（r值）达0．866；除覆盖1年、12年竹林，各竹林出笋与地温正相关水平不显著，但 r 值均在0．650以上。【结论】覆盖能提前笋芽萌发，延长笋期，提高笋产量，但随覆盖年限加长，笋产量持续下降，这与地下茎笋芽萌发能力降低有很大关系。此时，需要创新培育技术，重点开展竹林生态修复技术研究，以促进实现竹林可持续经营。

[Objective]The aim of the study was to revealed eco-physiological response mechanisms of mulching cultivation bamboo forest and to provided a basic evidence for modern directive breed-ing and ecological rehabilitation technology of bamboo forests.[Method]Contrasting design and correlation analysis were used in this study to explore shooting law and its correlation with tem-perature of mulching 0 year (control),1 year,3 years,6 years,9 years,12 years P .prevernalis forests.[Results]In all bamboo forests,the shooting time was earliest in mulching 1 year forest. Its shooting duration was longest and shoots yield was highest (16 633.93 kg/hm2 ).The shoots yield in 3,6,9 and 12 years forests were,respectively,15 422.97,12 004.90,11 652.36 and 10 288.25 kg/hm2 .The shooting time of was latest and shooting duration was shortest in the con-trol forest.Its shoots yield was lowest and only 8 173.60 kg/hm2 .All shooting of bamboo forests had no significant correlation with air temperature.However,control forest had the most signifi-cant correlation with air temperature and the correlation coefficient (r)reached 0.866.Except for 1 year and 12 years bamboo forests,shooting had no significant positive correlation with ground temperature but all r values were higher than 0.650.[Conclusion]Ground mulching advanced shooting time,prolonged shooting duration and increased shoots quantity.However,following the increase of mulching periods,the shoots yield decreased.This might be caused by shooting a-bility of bamboo rhizome.In this case,it was necessary to innovate cultivation technology.Mean-while,ecological restoration technology of degraded bamboo forest will needed for sustainable management of bamboo forest.
