Study on the Effect of the Use of FGD Gypsum into the Alkalization Soil to Improve Soil Property

Abstract:

Through this pot experiment of corns, the paper studied the effect of the use of FGD gypsum into the alkalization soil to improve corn output and soil property in the alkalization soil of the west of Jilin Province. The study indicated that FGD gypsum reduced effectively the PH value of the alkalization soil and improved the corn output. When the amount of FGD gypsum was 3t/667m², the growth index of planting corn, such as the plant height, root length, plant fresh weight, was the best. But when the amount of FGD gypsum was 2t/667m², the difference was not obvious. The results indicated that considering the factors of soil PH value and salt-resistance, when the amount of FGD gypsum was 2t/667m², the effect of the use of FGD gypsum of the alkalization soil in the west of Jilin Province to improve soil property was the best.
