摘要
为了解不同经营方式对4类竹林土壤理化性质的影响,采样分析了湖州市毛竹材用林、笋用林、早竹林和杂竹林土壤的理化性质。结果表明:容重、总孔隙度、非毛管孔隙度、有机质、全氮和全磷6项指标存在显著差异,杂竹林和材用林优于早竹林和笋用林。其中笋用林的容重最大(1.40 t.m-3),总孔隙度最小(46.97%)。有机质和全氮含量以杂竹林最高,依次为杂竹林>材用林>早竹林>笋用林,全磷含量依次为杂竹林>早竹林>材用林>笋用林。4类竹林土壤全K、水解氮、速效磷及土壤酸度状况均无明显不同。
In order to find out the effect of different management patterns on soil properties,the physical and chemical properties of soil under 4 types of bamboo-shoot forests in Huzhou were analyzed.The results showed that the soil physical properties and organic matter,total N,total P of small diameter bamboo forest and bamboo-timber forest were more excellent than that of Phyllostachys praecox forest and bamboo-shoot forest.The highest bulk density(1.40 t·m-3) and the lowest total porosity(46.97%) were found in t...
