摘要
采取人工施肥、补植与封山育林相结合的措施对福建长汀河田严重侵蚀红壤进行治理 (称封禁管理 ) ,对治理后的林地及对照的土壤持水性能、抗蚀性能、土壤化学性质、土壤酶活性、土壤微生物、土壤呼吸作用进行了研究 .结果表明 ,与对照相比 ,治理后土壤的持水性能和抗蚀性能有明显的改善 ,土壤养分贮量和速效性养分供应强度亦得到明显改善 ,土壤微生物总数明显增加 ,土壤水解性酶、氧化还原酶活性和土壤呼吸作用强度得到显著加强 ,但它们的绝对数值与正常的土壤相比都还较小 .表明采用封禁管理进行治理是改良严重侵蚀红壤的有效途径之一 。
Serious eroded red soil were controlled by closing of hillsides and management to facilitate afforestation in Hetian town,Changting county,Fujian,and the soil water holding ability,soil antierodibility, soil chemistry,soil enzymes,soil microbes,soil respiration of the controlled pattern and contrast were studied in 2000 The results showed that the soil water holding ability and soil antierodibility were improved obviously,the storage of soil nutrients and the intensities of various available nutrients supplies had showed pronounced improvements,the amounts of soil bacteria,fungi,actinomyces and total microbe were increased obviously,and the soil hydrolytic and the oxidation reduction enzymes and soil respiration were also strengthened evidently,demonstrating that the soil fertilities of the pattern were resumed to some degree after harness,but their absolute quantities still lower normal soil's Therefore,closing of hillsides and management to facilitate afforestation are effective to improve the fertility of red soil of serious degradation,and the eroded degraded ecosystem restoration was a very long process
