摘要

Application of organic waste to saline alkaline soils is considered to be a good practice for soil remediation.The effects of applying different organic amendments (e.g.,cattle dung,vermicompost,biofertilizer) and earthworm inoculations (Eisenia fetida) on saline soils and cotton growth were investigated during 1 year of cotton cultivation.Compared to the control (applied with inorganic NPK fertilizer),applying organic amendments improved soil physicochemical properties.Biofertilizer application improved available nutrient content,reduced short-term soil electrical conductivity,and produced the highest cotton yield,whereas cattle dung and vermicompost applications resulted in higher soil organic matter content.Application of organic amendments significantly increased soil microbial biomass carbon during the flowering period,which sharply declined at harvest.This was especially true for the biofertilizer treatment,which also exhibited lower nematode abundance compared with the other organic materials.Earthworm inoculation following cattle dung application failed to significantly change soil physicochemical properties when compared to the treatments without earthworm inoculation.Results suggest that biofertilizer application to saline soil would improve soil nutrient status in the short-term,whereas cattle dung application would improve soil organic matter content and increase soil organism abundance to a greater extent.However,different strategies might be required for long-term saline soil remediation.
