Abstract

The invention relates to a method for preparing a fertility-increasing and detoxifying type acidic soil conditioner, and belongs to the technical field of acidic soil treatment. The method comprises the following steps: mildewing biomass wastes pig manure and mushroom bran which are used as raw materials, charring the mildewed raw materials to obtain high-porosity biomass charcoal, oxidizing the biomass charcoal with concentrated sulfuric acid and potassium permanganate, performing blending fermentation on the oxidized biomass charcoal and grape skins and ginger skins containing amino acids and flavonoids, performing microbial degradation to degrade the amino acids and flavonoids in order to produce a large number of free carboxyl and carbonyl groups, introducing the carboxyl and carbonylgroups to the surface of the charcoal under the self-crosslinking action of microorganisms to obtain a fermentation product, performing mixing impregnation on the fermentation product and a sodium alginate solution, concentrating the obtained solution, freeze-drying the concentrated solution, and crushing the freeze-dried concentrated solution to obtain the fertility-increasing and detoxifying type acidic soil conditioner. The fertility-increasing and detoxifying type acidic soil conditioner has the advantages of increase of the pH value of the soil, alleviation of aluminum toxicity, improvement of the fertility of the soil, and broad application prospect.

Description

technical field [0001] The invention relates to a preparation method of a fertilizer-enhancing and detoxifying acidic soil amendment, belonging to the technical field of acidic soil treatment. Background technique [0002] Various chemical and biochemical reactions exist in the soil, resulting in different acid-base characteristics of the soil. The acidic soil in our country is mainly distributed in tropical and subtropical regions. Due to the high temperature and rainy seasons in these regions, the weathering and leaching of the soil are strong, the iron and aluminum oxides are obviously enriched, the soil base saturation is low, and the pH is generally in the The range of 4.5-6.0. [0003] Acidification occurs with soil weathering and pedogenesis. Under rainy natural conditions, the amount of precipitation greatly exceeds the amount of evaporation, and the leaching effect in the soil is very strong, which makes the base ions in the soil solution easily move down with the...
