| 摘 要： | 赤红壤严重侵蚀地经不同措施治理后，土壤结构、水分状况得到改善，土壤腐殖质品质亦有所改善，土壤营养元素容量及供应强度得到明显加强，土壤微生物数量急剧增加，土壤呼吸作用和酶活性显著加强，土壤肥力处于恢复之中。其中豆科树种(大叶相思)改良土壤效果最好，单一种果措施则相对较差。引进豆科植物增加果园覆盖或敷盖是该地区侵蚀劣地治理及地力改良重要技术措施之一。

| Abstract: | By taking different harness measures the latertic red soil of serious erosion were controlled. After that, soil structure, moisture, soil humus quality were improved. Soil nutrients storage and intensity of available nutrients supplies had showed a pronounced improvements. Soil enzymes activities and soil respiration were strengthened evidently. Soil fertility was recovered. Leguminous tree was the best while plant fruit tree alone was poor for improving soil. To introduce legume into orchard to increase coverage is one of the effective measures to control the seriously deteriorated latertic red soil. |
