    摘要:

    采用营造大叶相思水土保持林和种植荔枝、龙眼、杨梅等果树的措施治理严重退化赤红壤,对不同治理措施及对照的土壤抗蚀性研究,结果表明:采用不同生物措施治理后土壤抗蚀性大小顺序为:27年生杨梅(T23);6年生大叶相思(T12)、28年生的荔枝(T21)、龙眼(T22)和6年生荔枝(T11)。采用受蚀性指数EVA、土壤有机质、结构体破坏率、大于1mm水稳性团粒含量以及侵蚀率,能较好地表征赤红壤抗蚀性。在果园中引进以豆科为主植被覆盖地表,是提高严重退化赤红壤治理与合理开发综合效益重要措施之一。

    Abstract:

    The measures of afforesting soil and water conservation forest of Acacia auricalaformis and cultivating fruit trees of Iitchi chinensis, Euphoria longana,Myrica rubra were took to control soil erosion on the lateritic red soils of serious deterioration area. Antierodibility under different treatments and controls were studied, the results showed that the order of the soil antierodibility followed: Myrica rubra of 27 year-old(T23);Acacia auricalaformis of 6 years-old (T12), Iitchi chinensis and Euphoria longana of 28 year-old (T21,T22); Litchi chinensis of 6 year-old (T11). Index of erodibility (FVA), organic matter;>1mm water-stable aggregate composition, rate of structure deterioration, and erosion raito could be used to indicate the lateritic red soil antierodibility in this area. To introduce legume into orchard for increasing coverage is one of the effective measures to enable the combined effect of harness and development in seriously deteriorated lateritic red soil.
