【摘要】 用常规方法对东江流域红苞木Rhololeia championii×枫香Liquidambar formosana混交林、稠木Lithocarpusthalassica×红锥Castanopsis hystrix混交林、荷木Schima superba×稠木混交林、格木Erythroploeum fordii×红苞木混交林、樟树Cinnamomum camphora×马占相思Acacia mangium混交林和米老排Mytilaria laosensis×枫香混交林造林后2年的土壤肥力变化进行了分析.结果表明,6种林分中,红苞木×枫香混交林的有机质和养分最丰富.6种林分的土壤酸性均有所减弱,降幅2.22%~9.85%.除个别林分外,其余林分土壤有机质和养分含量均有减少,最大降幅达74.12%.更多还原

【Abstract】 Changes of soil fertility for two years was analyzed by conventional methods in mixed young stands of Rhololeia championii × Liquidambar formosana,Lithocarpus thalassica × Castanopsis hystrix,Schima superba × Lithocarpus thalassica,Erythroploeum fordii × Rhodoleia championii,Cinnamomum camphora × Acacia mangium and Mytilaria laosensis ×Liquidambar formosana.The results showed that the soil fertility of mixed young stands of Rhololeia championii × Liquidambar formosana was highest among six mixed stands.Soil acidity decreased in all stands,the range of fall was from 2.22% to 9.85%.Except for individual stand,the contents of organic matter and nutrients decreased,the maximum range of fall was 74.12%.更多还原
