不同耕深下高碳基土壤修复肥对土壤保育和烟叶品质的影响
Effects of high carbon-based soil remediation fertilizers on soil conservation and tobacco quality at different tillage depths
摘要
Abstract
[Purpose]To explore the effects of high carbon-based soil remediation fertilizer on tobac-cotic soil conservation and tobacco leaf quality under different topsoil depths,and to provide theo-retical reference for tobaccotic soil conservation and high-quality tobacco leaf production.[Meth-ods]Tobacco-growing soil was used as the object.Field experiments were conducted with four treatment:tillage depth of 20 cm+conventional fertilization(CK),tillage depth of 20 cm+900 kg·hm-2 high carbon-based soil remediation fertilizer+conventional fertilization(T1),tillage depth of 40 cm+conventional fertilization(T2)and tillage depth of 40 cm+900 kg·hm-2 high carbon-based soil remediation fertilizer+conventional fertilization(T3).The effect of different treatments on soil conservation and tobacco leaf quality were evaluated.[Results]Compared with CK,the application of high carbon base soil repair fertilizer significantly increased the soil pH,total nitrogen,total carbon,available phosphorus,available potassium and organic matter con-tents by 16.41％,26.45％,37.96％,13.49％ and 38.13％,respectively.Under deep plough-ing conditions,the application of high carbon-based soil repair fertilizer increased the α diversity of soil bacteria and the richness of bacterial community,significantly increased the Shannon index,ACE index and Chao index of bacterial community,and decreased Simpson index.The relative abundance of Firmicutes and Acidobacteriota was also increased by applying high carbon-based soil remediation fertilizer.In terms of tobacco quality,the combined application of high carbon base soil repair fertilizer under deep ploughing conditions improved the physical indexes of cured tobacco,and significantly increased the content of total sugar,reducing sugar,potassium,ratio of two sugars and total neutral aroma substances in cured tobacco by 7.45％,31.23％,15.39％,11.25％and 32.04％,respectively.[Conclusion]The application of high carbon-based soil remediation fertilizer under deep tillage conditions can improve the physicochemical proper-ties and bacterial community structure of tobacco-growing soil,coordinate the chemical composi-tion of tobacco leaves,increase the content of neutral aroma substances in tobacco leaves,and ultimately improve tobacco leaf quality.关键词
