Abstract

The effects of the application of different soil conditioners (biochar produced by corn straw and sludge, FGD-gypsum and its compounds) on soil structure were studied by pot experiment with saline soil in Baotou city west, Inner Mongolia autonomous region. The results showed that separate application of biochar can significantly improve the soil nutrient content, although corn can largely absorb soil nutrients with the corn growth, soil nutrient was still higher nutrient content than without any processing of saline soil. Separately applied FGD-gypsum has significant effect on the lowering soil alkalinity and salinity, soil pH is on the decline after application of desulfurization gypsum (0 to 80 d), pH decreased by 0.74 units, and the FGD-gypsum has good desalting, soluble salt content in soil after planting corn was reduced by 22.55%,25.60%,33.74%,44.07% and 45.41%, respectively. Its compounds can reduce saline soil salinity and increase the content of nutrients in the soil, and has a promoting effect on maize growth and biomass.
