Embodiment 1

[0016] A preparation method of a micropowder soil conditioner, comprising the following steps: first, the raw material of the activated carbon is walnut shell powder, a certain amount of walnut shell powder is weighed and soaked in 60% KOH aqueous solution for 10 hours, and then Activate the KOH aqueous solution of walnut shell powder at 500°C with nitrogen gas for 5 hours at high temperature, then cool, wash, dry, and grind to obtain activated carbon; Chitosan, mass fraction is 10% lime, mass fraction is the described activated carbon of 20% and mass fraction is 5% microbial flora powder, surplus is water, comprises cyanobacteria, protogreen in the described microbial flora powder Bacteria, acidophilus; Then, chitosan, lime, activated carbon and water are added in the mixer successively to form a mixture, and the mixture is stirred and mixed at room temperature for 48 hours; finally, the mixture in the mixer is taken out, The mixture is put into a vacuum drying oven, dried un...

Embodiment 2

[0018] A preparation method of a micropowder soil conditioner, comprising the following steps: first, the raw material of the activated carbon is walnut shell powder, a certain amount of walnut shell powder is weighed and soaked in 40% KOH aqueous solution for 10 hours, and then Activate the KOH aqueous solution of walnut shell powder at 600°C with nitrogen gas for 3 hours at high temperature, then cool, wash, dry, and grind to obtain activated carbon; Chitosan, mass fraction are 5% lime, mass fraction are 10% described activated carbon and mass fraction are 10% microbial flora powder, the balance is water, and comprise cyanobacteria, protogreen in the described microbial flora powder Bacteria, acidophilus; Then, chitosan, lime, activated carbon and water are added in the mixer successively to form a mixture, and the mixture is stirred and mixed at room temperature for 48 hours; finally, the mixture in the mixer is taken out, The mixture is put into a vacuum drying oven, dried...

Abstract

The invention relates to a preparation method of a micro powder soil conditioner. Chitosan, lime and activated carbon are stirred and mixed to form a mixture, and then the mixture is evenly mixed with microbial flora powder to form the conditioner. Due to the fact that the activated carbon has an abundant pore structure, when the activated carbon is stirred through a material mixer, part of Ca(OH)2 can be adsorbed into a chitosan polymer, another part of the Ca(OH)2 enter into the pores of activated carbon molecules, the Ca(OH)2 entering the activated carbon can slowly infiltrate into soil from activated carbon to achieve a sustained Ca(OH)2release effect, fixing of nutrients in the soil due to excessive alkali is not caused, and the loss of the nutrients in the soil is prevented. In addition, the activated carbon can also absorb the heavy metal elements in the soil, and the problem of soil heavy metal pollution is solved. Furthermore, the microbial flora powder can degrade organic pollutants in soil and convert them into nutrients which can be absorbed by plants in growth, and conditioning of the nutrient structure of the soil is achieved.

Description

technical field [0001] The invention relates to the technical field of preparation methods of soil conditioners, in particular to a preparation method of micropowder soil conditioners. Background technique [0002] Soil is the basic means of production for human beings and the material basis for human survival. Soil pollution not only directly leads to the reduction of food production, but more importantly, pollutants will affect human health through the food chain, posing a great threat to human health. [0003] Soil conditioning is the process of taking corresponding physical, biological or chemical measures to improve soil properties, soil fertility, crop production, and the soil environment for human survival in response to the poor texture and structure of the soil. Soil conditioning mainly includes acidification soil conditioning, heavy metal pollution conditioning and soil nutrient conditioning. However, the existing soil amendments have single effects and cannot so...
