有机肥对玉溪植烟土壤有机质组分和微生物群落结构的影响
Effects of Organic Fertilizer on Organic Matter Composition and Microbial Community Structure of Tobacco-Growing Soil in Yuxi
摘要
Abstract
In order to further clarify the effects of increased application of organic fertilizer on the microecological environment of tobacco-growing soil and its internal interaction,a field experiment was conducted to apply organic fertilizer(0,3 000,6 000 and 12 000 kg·hm-2).The effects on composition,physicochemical properties and microbial community characteristics of soil organic matter were studied.The results showed that increased application of organic fertilizer significantly increased pH,organic matter and available nutrient contents of tobacco-growing soil.With the increase of organic fertilizer application amount,the contents of soil particulate organic matter,water-soluble organic carbon,microbial biomass carbon and nitrogen and light organic matter showed increasing trend,which organic matter content increased by 7%～28%,available potassium content increased by 10%～61%,microbial biomass carbon increased by 14%～20%and microbial biomass nitrogen increased more than 24%.The ACE indexes of bacteria and fungi in tobacco-planting soil were increased with the application of organic fertilizer.And the relative abundances of beneficial bacteria such as Proteobacteria,Basidiomycetes,Cladosporium and Pseudomonas in soil were increased obviously.The relative abundances of Bryobacter and Haliangium decreased significantly,and were negatively correlated with active organic matter.In conclusion,the application of organic fertilizer stimulated the growth and propagation of soil microbial community,increased the active organic matter component of tobacco planting soil,and improved soil physical and chemical properties.关键词
