我国植烟土壤修复的研究进展

Research Progress on Tobacco Planting Soil Restoration in China

土壤是植物生长重要的生态因素之一,土壤质量的好坏直接影响烟株的生长发育。土壤的不合理使用可导致植烟土壤出现一系列质量问题。近年来对植烟土壤的修复研究取得了一些成效。介绍了翻压绿肥、添加生物炭、秸秆还田、使用微生物肥料以及其他改良措施对植烟土壤的修复状况,分析论述了其对土壤的理化性状、土壤养分、土壤微生物多样性以及酶活性等的影响,结合近年来植烟土壤修复的现状分析了存在的问题,并提出了增加植烟土壤改良物质的研究深度以及应用现代生物技术的建议,以期为植烟土壤修复的进一步研究提供思路。

Soil is one of the important ecological factors for plant growth.Soil quality has a direct influence on the growth and development of tobacco.Due to the unreasonably using of land,a series of prolems appeared in tobacco soil,some achievements have been made on the research of tobacco soil remediation in recent years.This paper introduced the green manure,biological activated carbon,reusing of crop straws,microbial fertilizer and other improvement measures to tobacco soil repair status,and mainly analyzed from the soil physical and chemical properties,soil nutrients,soil microbial diversity and enzyme activities.Combining with the improvement of tobacco soil conditions in recent years,this paper analyzed the existing problems,and put forward some suggestions for future research,for example,reseach depth of soil improvement materials and application of modern biotechnology,hoping to provide research approaches for the remediation of tobacco soil in the next step.
