摘　　要：盐碱土是全球耕地的重要组成部分,由于土壤含盐量、碱化度的增加,土壤的理化结构变差、保水保肥能力降低。改良盐碱土是促进土壤利用、提高土壤农业生产能力及土壤综合效益的重要方法之一。木醋液作为富含有机酸类物质的改良剂在盐碱土改良方面具有独特优势,关于木醋液直接作用于作物来影响作物产量、品质的研究较多,但是对土壤尤其是盐碱土改良作用系统研究较少。本文通过综合分析近年来木醋液在盐碱土理化性质、养分利用、碳氮循环和微生物作用方面的研究进展,总结了木醋液在盐碱地改良中的潜在作用机制,并对木醋液在盐碱地的研究、应用前景进行展望,以期为木醋液资源回收利用和盐碱地的生态治理提供思路。Saline-alkali soil is an important part of cultivated land in the world.Due to the increase of soil salt content and alkalinity,the physical and chemical structure of soil becomes worse and the ability of water and fertilizer conservation decreases.Improving saline-alkali soil is one of the important methods to promote soil utilization,improve soil agricultural production capacity and soil comprehensive benefits.As a modifier,which riches in organic acids,wood vinegar has unique advantages in the improvement of saline-alkali soil.There are many studies on the direct effect of wood vinegar on crops to affect crop yield and quality,but there are few systematic studies on the improvement of soil,especially saline-alkali soil.By comprehensively analyzing the research progress of wood vinegar in the physical and chemical properties,nutrient utilization,carbon and nitrogen cycle and microbial action of saline-alkali soil in recent years,this paper summarizes the potential mechanism of wood vinegar in the improvement of saline-alkali soil,and prospects the research and application prospect of wood vinegar in saline-alkali soil,in order to provide ideas for the recycling of wood vinegar resources and the ecological management of saline-alkali soil.
