Abstract

The invention relates to a soil improver and a preparation method thereof, belonging to the technical field of water and soil restoration. The preparation method comprises the following steps: carrying out filter-press and airing on dredged sludge, crushing, and sieving to obtain pretreated dredged sludge; airing animal dung, crushing, and sieving to obtain pretreated animal dung; carrying out ball milling on coal ash, vermiculite, diatomite and zeolite, and sieving, so as to obtain composite mountain flour; weighing the pretreated dredged sludge, the pretreated animal dung, furfural residue,the composite mountain flour, magnesium humate and calcium humate, uniformly mixing with a glucose solution, carrying out autoclaved sterilization, so as to obtain a cultured matrix; and uniformly spraying an EM fungicide to the surface of the cultured matrix, uniformly mixing, putting the mixture into a fermentation tank, covering with a layer of plastic film, stacking for fermentation, turning the stack once every 7 days, adding deionized water, controlling the water content, and after the fermentation is finished, putting the ferment into a drying tank, drying to constant weight, transferring the ferment into a crushing machine, crushing the ferment into particles, and packaging and bagging the particles, so as to obtain the soil improver.

Description

technical field [0001] The invention relates to a soil conditioner and a preparation method thereof, belonging to the technical field of water and soil restoration. Background technique [0002] Agriculture is the most basic material production activity that human beings rely on for survival, and it is the main source of food and basic living guarantee for human survival activities. The sustainability, high yield, high efficiency and high quality of agriculture have gradually become the focus of modern agriculture. As a non-renewable natural resource and means of agricultural production, soil plays a crucial role in the agricultural ecosystem, directly affects various characteristics of agriculture, and is inseparable from agricultural production. At present, agriculture, as the core strategy of my country's development, is at the center of all industries in terms of ensuring the food security and living standards of my country's 1.3 billion people. At the same time, moder...
