Effects of salinealkaline soil conditioner on the growth of maize and the improvement of soil were studied using pot experiment.The salinealkaline soil conditioner was made of furfural residue,humicacidurea and other ingredients.The results showed that compared with chemical fertilizer treatment,for the salinealkaline soil conditioner treatments,the maize biomass increased by 1.86% to 48.56%;Chlorophyll content increased by 2.60% to 4.77%,plant nitrogen,phosphorus and potassium uptake increased by 3.51% to 64.2%.Soil organic matter content increased by 12.77% to 14.28%,the soil nitrogen,phosphorus and potassium content increased by 0.70% to 9.46%.Soil moisture content increased by 11.29% to 11.36%,soil pH fell 0.03.Soil EC25 reduced by 15.8% to 20.10%.All this suggested that salinealkaline soil conditioner promoted the growth of maize,enhanced the photosynthetic capacity of maize leaves.
