腐植酸对植烟土壤的改良修复和烟叶品质影响研究进展

The Progress of Humic Acid on Conservation and Remediation of Tobacco-growing Soil and Tobacco Leaf Quality

植烟土壤状况是影响烟叶品质的重要因素,加大植烟土壤的保育,才能生产出优质烟叶。分析了腐植酸对植烟土壤酸碱度、养分、水分状况、物理特性、微生物、酶活性等的影响及对养分失衡、受污染植烟土壤的修复效果,简要总结了植烟土壤上施用腐植酸对烟叶品质的影响,提出了今后烟草上推广使用腐植酸的重点工作,可为植烟区通过腐植酸改良修复土壤提供参考。

As the regime of tobacco-growing soil is an important factor that influence the quality of tobacco, it is nec- essary to conserve of planting tobacco soil for producing high quality tobacco leaves. Based on experiment data of pH, nutrients, water status, physical properties, microorganism and enzyme activity in tobacco-growing soil, the effects of humic acid on nutrient unbalance and soil remediation were discussed. The key point of promoting the use of humic acid on tobacco was suggested to provide proper advises for tobacco-growing areas.
