摘　　要：绿竹是一种优良笋竹两用丛生竹种,针对绿竹林存在土壤铅含量超标污染竹笋的风险,开展土壤有效态铅对绿竹笋材生长的影响研究。结果表明,土壤有效态铅对绿竹笋生长影响明显,土壤有效态Pb含量在15.0 mg·kg^(-1)<Pb≤20.0 mg·kg^(-1)时笋产量最高,并且最大单体重和最大单体直径均最大。土壤有效态Pb含量在超过20.0 mg·kg^(-1)对绿竹笋生长具有明显的影响,高浓度土壤有效态Pb含量,对绿竹笋产量与品质的提高构成威胁。Bambusa oldhamii Munro is an excellent shoot bamboo species,in order to explore the enrichment ability of understory vegetation of B.oldhamii forest to heavy metals and screening the main heavy metal enrichment plants.The research results indicated that soil available plumbum has a significant impact on the shoots growth.When the content was between 15.0 to 20.0 mg·kg^(-1),the highest yield of bamboo shoots was achieved,and the maximum individual weight and diameter was both the largest,which was most conducive to the growth of shoots.When soil available Pb 20.0 mg·kg^(-1)has a significant impact on the growth of green bamboo shoots,means high concentrations of soil available Pb content pose a threat to the improvement of yield and quality of B.oldhamii shoots.
