湖南紫鹊界梯田区森林改良土壤作用研究
- Title:
- Study on Improving Soil Properties of Forest Vegetation in Ziquejie Terrace
- 分类号:
- S714.6
- 摘要:
- 研究了湖南紫鹊界梯田区林地对土壤理化性质的影响，探讨紫鹊界梯田区森林改良土壤作用，旨在为梯田的可持续发展服务。结果表明：（1）林地表层土壤物理性黏粒（<0.01mm）含量、总孔隙度、毛管孔隙度、非毛管孔隙度、通气性、最大持水量和毛管持水量均比梯田或荒坡高，林地土壤容重较梯田或荒坡低。紫鹊界梯田区森林对土壤物理性状有明显的改良作用。（2）林地表层土壤有机质、全氮、全钾、水解氮等营养元素贮量及速效性养分供应状况亦比荒坡高。紫鹊界梯田区天然林覆盖下的土壤具有良好的自我培肥功能。湖南紫鹊界梯田区森林对土壤物理化学特性有明显的改良作用。
- Abstract:
- The influence of forest soil on the physicochemical properties of soil in the Ziquejie terrace was studied. Forest in the Ziquejie terrace for soil improvement action was discussed. The purpose is service for sustainable development of the terrace. The result showed that soil physical clay particle content, total porosity, capillary porosity, noncapillary poropsity, soil aeration, maximum water holding capacity and capillary moisture capacity were all higher than that of terrace and hillsides. Soil organic matter, total nitrogen, total nitrogen and potassium, hydrolysis nitrogen was all higher than that of hillsides. Protection forest has obvious amelioration on soil.
