摘  要：
为给科学合理施肥及集约经营管理毛竹林提供参考,对常宁市平衡施肥毛竹林的叶片养分含量与土地肥力及产量进行相关性研究。结果表明:土壤中影响竹叶N素含量的主要因子是有机质、速效P、活性酸、速效N、全K;对叶片中P含量的影响从高到低依次为土壤中活性酸含量、速效K含量、盐基代换量、全K含量、速效P含量、速效C a含量、速效N含量、pH值;全N、速效N、速效P、全K、活性酸与竹叶中K元素的含量较密切。通过回归分析得出了竹叶N、P、K元素含量与土壤肥力的相关模型及竹叶养分含量与竹林产量的相关模型。

摘  要：
In order to provide reference for scientific and rational fertilization and management of Phyllostachys pubescens forest,correlation of leaf nutrition and soil fertility with output of P.pubescens in Changning City was studied through balance fertilization.The results showed that N content in bamboo leaf was affected mainly by the factors,for example,organic matter,rapidly available P,activated acid,rapidly available N and total K in soil;influence from high to low on P content in bamboo leaf was activated acid content,rapidly available K content,base-exchange capacity,total K content,rapidly available P content,rapidly available Ca content,rapidly available N content and pH value in soil in order;K content in bamboo leaf had close relationship with total N,rapidly available N,rapidly available P,total K,activated acid.The model of N,P,K contents in bamboo leaf and soil fertility and the model of leaf nutrition and bamboo output were established through regression analysis.
