Description
Technical Field
The invention relates to the technical field of soil conditioners, in particular to a biomass charcoal soil conditioner containing biostimulant and a preparation method thereof.
Background
Because of the influence of factors such as the quality of the grown soil, planting mode, fertilization, climate and the like, acidic soil with about 2 hundred million hectares of area is distributed in China at present. Most acid soils have a pH of less than 5.5, and some are even lower.
The soil acidification brings the following effects on agricultural production and human life, and firstly, the soil structure is deteriorated, the cation exchange capacity and the base saturation are reduced, the soil nutrient loss is serious, and the soil is poor and affects the normal growth of plants; secondly, the activity of soil microorganisms is influenced, so that the number of the soil microorganisms is reduced, and the growth and the activity of the microorganisms are inhibited, thereby influencing the decomposition of soil organic matters and the circulation of C, N, P, S in the soil; and thirdly, the activity of toxic metal elements in the soil is improved, and the toxic metal elements enter a food chain through crops, so that the health of human bodies is harmed.
The traditional method for improving soil acidification is lime application. Although the lime relieves the acidification degree of the soil within a certain range, the lime has low mobility in the soil, the surface soil is hardened due to the long-term and excessive lime application, the available nutrients are excessively calcified and cannot be absorbed by crops, the nutrient element imbalance is caused, and the heavy metal toxicity cannot be relieved.
