Problems solved by technology

[0005] The technical problem that the present invention mainly solves is: for traditional acidic soil conditioner not only makes the nutrient elements such as Ca, Mg, P in the soil run off, and makes the solubility of various metals and heavy metal compounds in the soil improve, has increased the heavy metal element to the environment. Harm, resulting in continuous deterioration of land quality defects, the invention provides a preparation method of biomass carbon-based acidic soil conditioner, the invention firstly utilizes livestock and poultry manure, sawdust, soil rhizobia, etc. to ferment to obtain soil nutrient base , and then ball mill dolomite and fly ash to make composite stone powder, then mix with soil nutrient base, and transplant pea plants to cultivate and grow, activate the nutrients in the soil during the growth of pea plants, and then heat the pea plants Decompose into biochar, mix it with cultivated soil powder after activation, and transfer it to a granulator to make granules, and make a biochar-based acidic soil conditioner after packaging and sealing. The biochar-based acidic soil conditioner prepared by the present invention Acidic soil conditioners can break soil compaction, loosen soil, improve soil air permeability, improve soil, water retention and drought resistance, enhance crop resistance, increase crop yield, improve the quality of agricultural products, restore the original ecology of crops, and greatly improve the survival of tree planting rate and agricultural output

Abstract

The invention relates to a preparation method of a biomass charcoal based acid soil regulator, and belongs to the technical field of a soil regulator. The preparation method disclosed by the invention comprises the steps of: firstly, carrying out fermentation by utilizing livestock manure, wood flour, soil rhizobium and the like to obtain a soil nutrient medium; then carrying out ball milling on dolomite, coal ash and the like to prepare composite stone powder; then mixing the composite stone powder with the soil nutrient medium, and transplanting pea plants to carry out culture growth; activating nutritional ingredients in soil by utilizing the growing process of the pea plants; then carrying out pyrolysis on the pea plants to prepare biomass charcoal; after activating the biomass charcoal, mixing the biomass charcoal with culture soil powder, and transferring a mixture into a granulator to prepare particles; after carrying out packaging and bagging, obtaining the biomass charcoal based acid soil regulator. The soil regulator prepared by the preparation method disclosed by the invention can break soil hardening, loosen the soil and improve gas permeability of the soil, has functions of improving the soil, storing water for drought resistance, reinforcing disease resistance of crops, improving yield of the crops, improving quality of agricultural products and recovering the original ecology of the crops, and greatly improves a planting survival rate and yield of the agricultural products.

Description

technical field [0001] The invention relates to a preparation method of a biomass carbon-based acidic soil conditioner, belonging to the technical field of soil conditioners. Background technique [0002] Soil is the most basic means of production for human beings and the material basis for human survival. In our country, land resources are not only very limited, but also a considerable proportion of soils have obstacle factors due to soil-forming factors or human factors, including erosion, poor texture, poor structure or arability, salinity, acidification, toxic substance pollution, There are bad soil layers in the soil that hinder the growth of plant roots, too much or insufficient soil moisture, low fertility or imbalance of nutrients, etc. Typically, these barrier soils are difficult to use, but in recent years amending them with soil conditioners has shown better results. [0003] Biochar is a solid product of high-temperature pyrolysis of biomass, which has many spe...
