Active modified soil fertilizer and preparation method thereof

Abstract

The invention provides an active modified soil fertilizer comprising the following components by weight: 3-8 parts of surfactant, 1-4 parts of probiotics, 2-10 parts of biological active enzyme, 1-5 parts of protein composition, 2-4 parts of mineral and 2-8 parts of seaweed. The probiotics are a combination of at least two of bacillus licheniformis, bacillus subtilis, pichia pastoris, chromatium okenii and streptomyces verticillatus, and the effective viable count of each is 3*109-2.00*109/mL. The probiotics are added to facilitate circulation of nutrients, and the mixed bacteria not only promote each other, but also promote the absorption of minerals, protein substances and the other nutrients, and can generally improve the composition of soil microflora, enhance the crop rhizospheric microbial activity, enhance the capability to dissolve phosphorus and release potassium, effectively increase the content of effective N, P and K in the soil and improve the soil fertility. At the same time, biological active enzymes and seaweed are added to further increase the content of organic matters and improve the capability to resist pests and diseases.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to an activity-improving soil fertilizer and a preparation method thereof. Background technique [0002] Soil improvement is aimed at the poor texture and structure of the soil, and corresponding measures are taken to improve soil properties and soil fertility. Soil improvement and restoration agent is an important application of soil improvement. However, the soil remediation and improvement agents currently on the market have many defects: one is that the raw materials used contain artificially synthesized polymer compounds, which are not easy to decompose in the soil and remain for a long time, which has potential safety hazards; Soils, such as acidic and alkaline soils, have no effective targets for heavy metal pollution and nutrient deficiencies, resulting in low efficiency of improvement and restoration, or even counterproductive effects; third, the long cycle and high cost...

Problems solved by technology

However, the soil remediation and improvement agents currently on the market have many defects: one is that the raw materials used contain artificially synthesized polymer compounds, which are not easy to decompose in the soil and remain for a long time, which has potential safety hazards; Soils, such as acidic and alkaline soils, have no effective targets for heavy metal pollution and lack of nutrients, resulting in low efficiency of improvement and restoration, or even counterproductive effects; third, the cycle of soil improvement is long and the cost is high, so it cannot be applied on a large scale

At present, there are microbial soil improvers that improve soil function, soil effective microbial content and biological activity, but the formula is relatively complicated and the cost is high
