土壤调理剂的研究和应用进展

综述了土壤调理剂的研究和应用进展。土壤调理剂目前尚无统一定义,且存在不同的分类方法,其主要功能包括改良土壤质地与结构、提高土壤保水供水能力、调节土壤酸碱度、改良盐碱土、改善土壤的养分供应状况、修复重金属污染土壤等。在土壤改良过程中,针对不同土壤障碍问题有针对性地选择土壤调理剂将达到较好的改良效果。然而,土壤调理剂在推广应用中也暴露出一系列问题,包括潜在的环境风险、功能定位和认识问题、产品质量良莠不齐、包装标识混乱等,因此亟待建立一套完善的土壤调理剂科学评价体系。

Advance in research and application of soil conditioner

This paper reviewed the progress in research and application of soil conditioner.There was no uniform definition of soil conditioner at present,but there were several different classification methods.The main functions of soil conditioner included improving soil texture and structure,improving water retention and water supply ability of soil,regulating soil pH value,treatment of alkali saline soil,improving soil nutrient supply,remediation of heavy metals pollution soil,etc.In soil improvement process,the appropriate conditioner would be chosen according to the different soil obstacle problem to the good improvement effect.However,soil conditioner application also exposed a series of problems,including the potential environmental risk problem,product function orientation and awareness problem,product quality problem,packaging and marking the problem such as the disorder,finally pointed out that a scientific evaluation system of soil conditioner should be established urgently.
