本文首次报道了利用沸石矿粉改良苏打盐碱土的试验结果。试验证明,沸石能吸附盐碱土中的Na~+、SO_4~(2-)等离子,施用沸石可以降低土壤pH值和碱化度,改善土壤结构状况,并能提高土壤交换量,使土壤向有利于作物生长的方向发展。供试作物在改良盐碱土上均获得了较大幅度的增产。研究的结果为苏打盐碱土的改良提供了新的物料和途径。
This paper reports for the first time the use of zeolite ore soda saline soil test results. It has been proved that zeolite can adsorb Na ~ +, SO_4 ~ (2-) ions in saline-alkali soil. The application of zeolite can reduce the pH value and alkalization degree of soil, improve the structure of soil and increase the amount of soil exchange, Conducive to the direction of crop growth. The tested crops in the improved saline-alkali soil have been more substantial yield. The results of the study provided new materials and ways for the improvement of soda-tar soils.
