湖州市材用笋用毛竹林土壤理化性质比较分析

Physical and chemical property difference in soil under bamboo-shoot and bamboo-timber forests in Huzhou

为了解毛竹林不同利用方式对土壤性质的影响 ,采样分析了湖州市材用、笋用毛竹林土壤的理化性质。结果表明 :材用竹林土壤有机质和水解氮含量明显高于笋用竹林 ,差异达极显著水平。材用竹林土壤体积质量较笋用竹林小 ,而土壤总孔隙度较笋用竹林大 ,其差异也均达极显著水平。 2类竹林土壤全氮、全磷、全钾含量及土壤酸度状况均无明显不同。表5参 1

In order to find out the influences of different land use of Phyllostachys pubescens on properties of soil,physical and chemical properties of soil under bamboo shoot forest and bamboo timber forest in Huzhou are analyzed.The findings show that the contents of organic matter and hydrolgsable nitrogen in the soil under bamboo timber forest are higher than those under bamboo shoot forest,the differences between those two kinds of soil being significant( P <0 01).Soil under bamboo timber forest has lower volume density and bigger porosity,the difference being significant( P <0 01).There is no apparent discrepancy in total N,total P,total K and acidity between soil under bamboo shoot forest and bamboo timber forest.
