摘要

PPROBLEM TO BE SOLVED: To provide a soil-improving material in the improvement of an acidic sulfate soil, improving the acidity of the soil by accompanying with progress of its oxidation also so as not to inhibit the germination or growth of plants. PSOLUTION: This soil-improving material is obtained by forming an artificial zeolite by performing a hydrothermal reaction of incineration ash with an aqueous solution of sodium hydroxide and ion-exchanging the artificial zeolite with a prescribed cation for reducing the content of sodium ion to 6 wt.%, preferably to 2 wt.%. The acidic sulfate soil is improved by adding water to the soil-improving material to make slurry and spraying the slurry on the surface of the acidic sulfate soil. Further, the acidic sulfate soil is improved by mixing the soil-improving material with a growth base material and spraying the growth base material on the surface of the acidic sulfate soil.

要解决的问题：提供一种用于改良酸性硫酸盐土壤的改良土壤的材料，通过伴随其氧化的进行来提高土壤的酸度，从而不抑制植物的发芽或生长。

解决方案：该土壤改良材料是通过以下方法形成的：人造沸石，其方法是将焚烧灰分与氢氧化钠水溶液进行水热反应，然后将人造沸石与规定的阳离子进行离子交换以减少钠离子的含量。至6重量％，优选至2重量％。通过向土壤改良材料中添加水以制成浆液并将浆液喷洒到酸性硫酸盐土壤的表面，可以改善酸性硫酸盐土壤。此外，通过将土壤改良剂与生长基础材料混合并将生长基础材料喷涂在酸性硫酸盐表面上来改善酸性硫酸盐土壤。
