Method for producing soil improvement material using wood crude fiber and fulvic acid or humic acid

摘要

Task It is known that organic acid components such as acetic acid are produced by explosive treatment of wood chips and organic acid components lower the pH of woody crude fiber so that when used as soil improvement material, Which makes it difficult to improve soil improvement performance.SOLUTION: Produced by immersing an undecomposed organic matter of trees, grasses, vegetable scraps or deciduous litter in an appropriate amount in pyroligneous acid or bamboo vinegar, which is a very strongly acidic organic acid produced in the process of producing charcoal and curing for a long time At least one fulvic acid or humic acid selected from the group of fulvic acid or humic acid, fulvic acid or humic acid extracted from humus soil, and fulvic acid or humic acid extracted from sedimentary earth at the bottom of the water, In the explosion treatment step S2 in which wood chips made of wood waste are subjected to explosive treatment to obtain wood crude fibers, they are added.BACKGROUND OF THE INVENTION
