桉树原料林基地土壤肥力评价与施肥策略

通过对广西理文公司在梧州市的四个植林区的实地调查研究和土壤样品分析,结果表明:调查地的土壤深厚、疏松,以强酸性砖红壤或红壤为主,碱解氮含量属中上水平,有机质、全氮、全磷、全钾和有效锌含量属中等水平,速效钾、代换性钙、有效铜和有效硼含量处于贫瘠状况,速效磷和代换性镁含量处于极贫状况。该地区地理气候和土壤立地条件比较适宜桉树的生长发育和桉树原料林的发展;推广应用测土配方科学施肥和营养诊断平衡施肥技术,确保桉树林地持续、稳定、健康发展。

Soil Fertility Evaluation and Fertilization Tactics of Eucalyptus Raw Material Forest Bases

The nutrient and fertility of soil samples were studied from four Forest Regions of Lee&Man Forestry Technology Limited in Wuzhou City.The results showed that the land solids were loose and thick soil layer mainly with strong acid latosol or red soil,rich in available nitrogen,but lack of available phosphorus and exchangeable magnesium.Contents of organic matter,total nitrogen,total phosphorus,total potassium,available boron belonged to moderate level.On the other hand,contents of available potassium,exchan...
