The techniques of saving water，reducing alkalinity and enhancing soil fertility in heavily saline-alkaline areas in Ningxia were developed to solve practical problems including equal emphasis on saline and alkali in soil，shortage of freshwater resources，and difficulties in the growth of crops in arid areas.Four organic materials including organic fertilizer，maize straw，furfural residue，and biochar were selected for combination with desulfurization gypsum.The treatment without any improved materials was used as a control.A series of bucket cultivation experiments were conducted in Huinong District，Ningxia to study the effects of gypsum irrigation with slightly salty water droplets combined with organic materials on the properties of alkaline and saline in soil and the growth of maize.The results showed that the application of gypsum increased the content of exchangeable calcium in the soil，significantly decreased the conductivity and pH in soil，with a decrease in conductivity of 28.3%-57.9%.The content of total nitrogen，alkali hydrolyzed nitrogen，available potassium，and organic carbon in the soil was significantly decreased，but the conductivity in soil increased and the content of available phosphorus decreased in the following spring.The combination of gypsum and organic fertilizer with 0.56% furfural residue or biochar further decreased the electrical conductivity in soil and increased the content of exchangeable calcium，maintaining the content of total nitrogen and available potassium in soil，significantly increasing the content of organic carbon，alkali hydrolyzed nitrogen，and available phosphorus in soil.The addition of 0.56% furfural residue combined with gypsum and organic fertilizer significantly mitigated the salinity and alkalinity in soil in the following year，while significantly increasing the content of organic carbon，total nitrogen，available phosphorus，and the cation exchange capacity in soil to significantly increase the plant height，stem diameter of maize，ultimately increasing the biomass of maize.It is indicated that the economic benefit of furfural residue is better than that of biochar，therefore，the combination of desulfurization gypsum combined with organic fertilizer and furfural residue is suitable for improving the alkalized solonchaks soil.
