    • PROBLEM TO BE SOLVED: To solve such problems that although it has been considered that in an artificial forest typified by a cedar forest or a Japanese cypress forest, forest functions can be restored by reducing the stand density therein through forest maintenance operations such as thinning, and pruning so as to assure an adequate light intensity in the forest, an artificial forest with an excessive planting density is kept at a low light intensity over a long period of time and therefore has a number of sites where the vegetation has not been recovered due to the marked progress of soil acidification; and in a strongly acidic site having special soil such as acidic sulfate soil where the soil pH significantly decreases, the improvement of the soil environment cannot be anticipated as long as the site is left untreated. SOLUTION: An acidity alleviation technique using converter slag includes, in a site to be treated, where the soil has been strongly acid due to a marked decrease in the soil pH, spraying soil dressing prepared by blending converter slag produced in making steel with an organic material or the like to the soil surface of the site to be treated using a vegetation base material-spraying machine to improve the structure of the soil which has been dysfunctional due to the marked decrease in the soil pH.

    • 要解决的问题:为了解决这样的问题,尽管已经认为在以雪松森林或日本柏树为代表的人造森林中,通过森林维护操作等来降低其中的站立密度可以恢复森林功能 为了保证森林中光照强度的变化,修剪,修剪,植被密度过大的人造林长时间保持在较低的光照强度,因此有很多植被没有 由于土壤酸化的显着进展而得到回收; 并且在土壤pH显着降低的酸性硫酸盐土壤等特殊土壤的强酸性位点,只要不进行处理,就不能预期土壤环境的改善。 解决方案:使用转炉渣的酸度缓解技术包括在待处理的地点,由于土壤pH值明显降低,土壤已经呈强酸性,通过混合在制钢中生产的转炉渣制备的喷涂土壤 使用植物基材喷涂机将待处理部位的土壤表面上的有机材料等改善由于土壤pH值显着降低而已经功能失调的土壤结构。 版权所有(C)2011,JPO&INPIT
