毛竹纯林留养阔叶树后土壤理化性质的研究

Effect of remain broad-leaved trees in Phyllostachys heterocycla forest on physical and chemical properties of the soil

对闽侯县荆溪镇仁洲村毛竹纯林留养阔叶树林与毛竹纯林的土壤理化性质的分析研究结果表明:毛竹留养阔叶树后,土壤容重、毛管持水量、总孔隙度及非毛管孔隙度等物理性状都得到了改良;林地土壤有机质含量增加,土壤全氮、水解氮及有效磷等养分指标普遍比毛竹纯林土壤高。由此可知毛竹留养阔叶树能更好的培肥土壤,提高林分水源涵养力,改善土壤的理化性质。

This article analyses effects of pure Phyllostachys heterocycla stand remain the broadleaf forest and pure Phyllostachys heterocycla stand on soil physical and chemical properties of the Renzhou village, Jingxi town, Minhou County, Fujian province , The result shows that ： after pure Phyllostachys heterocycla stand remain the broad - leaved trees, the soil pore -formed improved, such as soil volume weight , total porosity, noncapillary porosity , capillary porosity , soil aeration and rate of porosity have been improved and the amount of organic nutrients such as total nitrogen content, hydrolysis nitrogen and fast - acting phospohorus are generally higher than these on the soil of pure Phyllostachys heterocycla stand. So, pure Phyllostachys heterocycla stand remain thebroad - leaved trees play an important role in improving the soil＇s properties and enhance the role of soil raising buffer capacity of acidification,
