Abstract

The invention provides a biomass fertilizer for improving soil and a preparation method. According to a technical proposal, the biomass fertilizer is prepared from the following raw materials by weight percentage: 65%-85% of biomass char, 10%-20% of silicon potash fertilizer, and 5%-25% of pyroligneous liquor (diluted by 100-1000 times). Specifically, the biomass char has an average particle size of 1-5mm, the silicon potash fertilizer is solid powder with an average particle size of 50-200, the pyroligneous liquor is biomass pyrolysis liquid aqueous phase with pH of 3-6, and the dilution ratio is 100-1000. The biomass fertilizer provided by the invention loosens soil, improves soil structure, enhances the soil water storage capacity, reduces soil pesticide residue, increases the soil fertilizer efficiency, raises the soil activity, improves the soil resistance to diseases, insects and bacteria, and promotes the growth of crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biomass fertilizer for improving soil and a preparation method thereof. Background technique [0002] my country has a vast territory, but the area of ​​arable land used for agricultural production is relatively small, and it has been decreasing year by year in recent years. my country is one of the countries with the largest protected area planting area in the world. In order to ensure our country's food supply, a large amount of pesticides and chemical fertilizers have to be used in the process of agricultural production, which makes soil compaction and pesticide residues common. [0003] Biomass semi-coke, wood vinegar and silicon-potassium fertilizer are by-products of rapid pyrolysis of agricultural and forestry biomass. A large amount of biomass semi-coke is produced in my country every year. At present, most of the biomass semi-coke is directly incinerated, which no...
