气象因子对杜仲剥皮再生的影响

Influence of Meteorological Factors on the Bark Regeneration of Barked Eucommia ulmoides

根据杜仲生物学特性和生态气候特征，对气象因子影响杜仲剥皮再生进行５年多的研究和探索，得出杜仲环剥与生态气候因子关系密切，尤以降雨量、日照等因子为主导因子，具备适宜的主导气象因子的最佳时期，为５月上、中旬前后。这段时期环剥树剥面愈合率高，达８５％以上；植株成活率可达１００％；再生新皮年生长厚度可达１．

Influence of meteorological factors on the bark regeneration of barked Eucommia ulmoides were investigated for 5 years according to the biological features of E. ulmoides and ecoclimatic characteristics in Cili County. It has been found that some meteorological factors such as precipitation and length of day are the main factors to determine the optimum time of bark peeling. The period of the first twenty days of May is optimum for bark peeling. The bealing rates of the barked surface at this period were high and all the barked plant survived. Moreover, regenerated bark grew fast(over 1.5mm in thickness).
