Embodiment 1

[0028] The fertilizer based on biochar comprises the following components, and the proportioning by weight is:

[0029] 10 parts of microbial bacteria liquid, 5 parts of shell powder, 5 parts of humic acid, 5 parts of urea, 5 parts of monoammonium phosphate, 5 parts of potassium dihydrogen phosphate, 2 parts of potassium sulfate, 2 parts of iron, and 1 part of boron.

[0030] Wherein, the microbial bacterial liquid is compounded by photosynthetic bacterial bacterial liquid and Bacillus subtilis bacterial liquid in a weight ratio of 1:3;

[0031] The preparation method of the shell powder is as follows: the shells are soaked in hydrochloric acid with a concentration of 0.6% by mass fraction for 0.5h, then washed by a spiral washing machine with a concentration of 0.4% sodium hydroxide solution for 0.1h, and washed by a spiral washing machine for 0.1h, After desalination and degreasing, it is dehydrated and dried through a drum dehydration sieve, and then enters a dryer for calc...

Abstract

The invention provides a method for preparing a fertilizer based on biomass charcoal, belonging to the field of fertilizers. According to the invention, modified shell powder and other raw materials are combined and mixed to prepare a bio-organic-inorganic compound fertilizer; the shell powder has a large specific surface area and forms a colloidal film on the surface of a fertilizer particle, andthe shell powder, together with amino acids and beneficial trace elements rich in the shell powder, constitutes a beneficial microbial culture medium for soil on the surface of the fertilizer particle to promote the mass propagation of microorganisms; at the same time, antibacterial and bactericidal abilities are obtained through loading of active nanometer titanium dioxide; and the modificationof the shell powder is catalyzed through calcination of a mixed reagent of titanium dioxide, sodium citrate and 1-(3-hydroxy-n-propyl)cyclopentanol. The fertilizer prepared in the invention realizes optimal application effect in different time periods through compounding of microbial agents with different proportions and has the advantages of promotion of crop growth, improvement of soil structureand colony groups, resistance to pests and diseases, etc.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a method for preparing fertilizers based on biochar. Background technique [0002] Fertilizer is a strategic material to ensure national food security, and it is the material basis for maintaining and improving soil fertility and realizing sustainable agricultural development. Fertilizers can be divided into organic fertilizers, inorganic fertilizers, and biological fertilizers according to their ingredients. Organic fertilizers contain a large amount of organic matter and contain a complete range of nutrients. The application of organic fertilizers increases the content of organic matter in the soil, which can improve soil physical, chemical and biological characteristics, fertilize soil fertility, and improve crop quality. However, organic fertilizers contain low nutrient concentrations. After being applied to the soil, they must be decomposed and rotted by microorganisms to release...
