| 摘 要： | 对不同经营密度和造林营林措施的巨尾桉林分林地的土壤化学性质、土壤酶活性、土壤结构和孔隙组成研究 ,表明合理经营密度以及采取合理的造林和营林措施的巨尾桉林分林地具有良好的培肥土壤能力 ,表现为提高土壤有机质、 N、 P、 K以及各种土壤酶活性 ;土壤团聚体、结构破坏率和土壤孔隙度均比对照好 ,尤其是密度 1 32 5株· hm-2的巨尾桉林分表现更为突出

| Abstract: | The soil chemical properties,soil enzyme activity,soil structure and soil pore components in hybrid of Eucalyptus Grandis×Eucalyptus urophylla plantation with different silvicultural density were investigated and compared The results showed that hybrid of Eucalyptus Grandis×E.urophylla stands with reasonable silvicultural density could enhance soil fertility,including the quantity of soil organic substances,the content of N,P and K,and the soil enzyme activity.Compared with the uncultivated land,the soil aggregate,structure damage rate and soil porosity in different stands were better,and the stands whose densities were 1 325 trees hm -2 were best. |
