Abstract

The invention discloses a soil acid conditioner and a preparation method thereof. The preparation method comprises the following steps that a first step S1, pre-treatment of flyash is conducted; a second step S2, the pre-treated flyash is mixed with straw powder and calcium lignosulfonate to obtain a mixture, the mixture is added into a lime water solution, and subjected to be stirred, mixed, anddried to obtain a material A; a third step S3, edible mushroom dregs are mixed with lime water and a fast-rotting agent to obtain a material B; a forth step S4, the material B is mixed with the material A, and activated sludge, bentonite, calcium magnesium phosphate, lime nitrogen, zinc sulfate are added to obtain a mixture; and a fifth step S5, the mixture is granulated and dried to obtain the soil acid conditioner. According to the soil acid conditioner, by adding the flyash and the straw powder which are subjected to alkaline treatment, the soil acidity of soil can be improved, the acid-base balance of the soil is adjusted, the problems such as soil hardening and nutrient loss are solved, the soil acid conditioner can further provide rich nutrients for crop production, the growth of crops is promoted, and the yield is increased.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a soil acid conditioner and a preparation method thereof. Background technique [0002] Acidic soil refers to the lack of alkali metals and alkaline earth metals in the soil and a large amount of adsorption of H + The soil with a pH<7 is mainly caused by carbonic acid in the rain, metabolites of microorganisms and plant roots, organic acids produced during the decomposition of organic matter, sulfuric acid produced by the oxidation of ferrous sulfide, and the decomposition of chemical fertilizers. Once the soil forms an acidic environment, it will not only cause poor growth and quality degradation of crops, but also lead to the loss of cations in the soil, resulting in the lack of nutrients such as potassium, calcium, magnesium, molybdenum, boron, and the activation of toxic heavy metal elements, affecting the activity of soil microorganisms. [0003] At present, there ...
