土壤改良剂研究现状及其在南方旱坡地的应用前景

Current situation and outlook of research and application of soil modifiers on slope cropland in South China

综述了土壤改良剂的研发概况以及土壤改良剂的分类、机理、应用效果及使用技术,并分析了土壤改良剂在南方旱坡耕地上的应用前景,指出施用土壤改良剂可明显改善南方旱坡耕地普遍存在的酸、毒、瘠、漏、板、蚀等多种障碍因素,可望成为提高旱坡耕地生产力的重要手段。

This paper reviewed the current research progress, as wen as the classification, mechanism, application techniques and application effects of soil modifiers, Meanwhile, it also discussed the prospect of their utilization on slope cropland in South China. It have been evident that soil modifiers were able to improve various constraints such as acidity, toxicity, infertile, leaking, hardness and erosion, which commonly exist on slope cropland in South China. It is expected that adoption of soil modifiers should be one of the effective approaches for enhancing the productivity of slope cropland.
