施用石灰改良酸性土壤的研究进展

摘 要：世界上酸性土壤分布广泛，危害严重。施用石灰是一项传统而有效的酸性土壤改良措施，可以中和土壤酸度，改善土壤的物理、化学和生物学性质，从而提高土壤养分有效性，降低Al和其它重金属对作物的毒害，提高作物的产量和品质。本文综述了施用石灰改良酸性土壤研究的一些新近进展，并讨论了施用石灰过程中应注意的几个问题。

Advance on study of liming on acid soils

Abstract: It’s a serious issue that acid soils are widely distributed in the world. Liming is an traditional and effective method to amend acid soils. It enhances the physical, chemical and biological properties of soil through its direct effect on the amelioration of soil acidity and its indirect effect on the mobilization of some soil nutrients, reduces Al and other heavy metals toxic to crop growth, and improves crop yield and quality. Some recent progress on liming was briefly reviewed and some suggestions were provided at the end of the article.
