掺拌不同废弃物对吹填土快速脱盐后土壤性质的影响
Effects of the Industrial and Agricultural Waste on the Soil Property after Rapid Desalting of Coastal Dredger Fill
摘要
Abstract
This study aims to explore effects of the industrial and agricultural waste as a soil conditioner to improve the soil property after soil rapid desalting.10 kinds of industrial and agricultural waste were selected, including furnace ash (LHZ) , sawdust (JM) , coarse sand (CS) , mushroom rods (MGB) , carbon (NWF) , humic acid fertilizer (FZS) , straw (JG) , vinegar residue (CZ) , xylose cinder (MTCZ) and rice husk (DK) , and treatment without the industrial and agricultural waste was as control (CK).The results showed that, compared with CK, the industrial and agricultural waste could decrease the soil bulk and the pH, increase the soil capillary porosity and non-capillary porosity, and also could increase the soil penetration rate.In 10 kinds of industrial and agricultural waste, JM was better than the other wastes in decreasing the soil bulk that decreased by 40.66％ compared to CK;LHZ was better in increasing the soil capillary porosity and non-capillary porosity that increased by 1.03 mm·min-1 and 3.43 percentages compared to CK;JM was better in increasing the soil penetration rate that increased by 31.18％ compared to CK;FZS was better in decreasing the pH that decreased by 7.74％ compared to CK.In conclusion, adding the industrial and agricultural waste could effectively improve the soil property after soil rapid desalting, and it worked best with JM and LHZ to improve soil structure, and it worked best with FZS to decrease pH.关键词
