脱硫废弃物施用对盆栽油葵碱化土壤微生物多样性的影响
Effect ofAppling Desulphurization Byproducts on Microbial Diversity in Alkaline Soil Under Potted-sunflower
摘要
Abstract
A sunflower pot experiment was conducted in Qianjin Farm of Pingluo County in Ningxia to study the effects of desulfurizatiun byproducts on the functional diversity of soil microbial communities in alkaline soil by Biolog Eeo-plate technology. The results showed that applying dasulfurization byproducts decreased soil pH by 0.06 - 0.29, decrease soil total salt content by 0.72 - 1.35 g/kg, significantly increased soil microbial activity and carbon source utilization level of microbial community; Carbohydrates, carboxylic acid, polymer and amino acid could be used as carbon sources in a higher level while amine and phenolic compounds in a lower level. However, only the proper applying amount of desulfurization byproducts could significantly increase soil microbial functional diversity, 2.5 - 7.5 g/kg of desulfurization byproducts was the reasonable amount in this study in improving soil physical and chemical properties as well as microbial activity under the irrigation conditions.关键词
