Embodiment 1
[0027] The present embodiment provides a kind of preparation method of special fertilizer for tea tree germination, comprising:
[0028] Take biochar, industrial ammonia and humic acid, stir and mix to prepare a mixed slurry; put the obtained slurry in a reaction kettle, and pass CO 2 . The suspension obtained by the reaction is subjected to solid-liquid separation, and the solid is dried to obtain the special fertilizer for tea tree germination.
Embodiment 2
[0030] The present embodiment provides a kind of preparation method of special fertilizer for tea tree germination, comprising:
[0031] Take biochar, ammonia water and humic acid, stir and mix, and prepare a mixed slurry; put the obtained slurry in a reaction kettle, and pass CO 2 , and add humic acid every 1min. After the reaction is completed, centrifugal separation is carried out, and the obtained solid is dried to obtain a special fertilizer for tea tree germination.
Embodiment 3
[0033] The present embodiment provides a kind of preparation method of special fertilizer for tea tree germination, comprising:
[0034] The biomass is carbonized at 450-530°C under oxygen-limited conditions to obtain pyrolysis gas and biomass charcoal. Combustion pyrolysis gas, collecting combustion flue gas; the heat generated by combustion can be used as a heat source for biomass carbonization.
[0035] The biochar obtained by carbonization is pulverized, and 10kg is stirred and mixed with 5kg ammonia water and 1kg humic acid to prepare a mixed slurry; Flue gas, react, and add humic acid 0.5kg every 2min until the end of the reaction.
[0036] The suspension obtained by the reaction is subjected to solid-liquid separation, and the solid is dried to obtain the special fertilizer for tea tree germination.

Abstract
The invention belongs to the technical field of fertilizers, and particularly relates to a preparation method of a special fertilizer for tea tree germination. The preparation method of the special fertilizer for the tea tree germination comprises the steps of: firstly preparing a mixed slurry of biomass carbon, ammonia water and humic acid, and then introducing CO2 or a gas containing CO2, separating products, drying, and obtaining the special fertilizer for the tea tree germination. The application is different from the direct mixing of biomass carbon and ammonium hydrogen carbonate, adoptsthe biomass carbon with a surface rich in acidic functional groups as a crystal nucleus/carrier, and prepares a biomass carbon-based compound fertilizer through a physical chemical adsorption-chemicalreaction method. That is, the special fertilizer is obtained by reacting NH3+CO2+H2O on the inner and outer surfaces of pores of the biomass carbon, and organic combination with the biomass carbon and humic acid ensures the comprehensive utilization of nitrogen, and has a significant effect on the spring germination of tea trees; and the special fertilizer has high stability, achieves an effect of sustained release, overcomes the shortcomings of a traditional carbon ammonium fertilizer easy to decompose and volatilize, and effectively improves the utilization rate of the fertilizer.
Description
technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a method for preparing a special fertilizer for tea tree germination. Background technique [0002] In recent decades, the output and quality of tea in my country have been greatly improved, and the renewal of fertilization technology has played an irreplaceable role. Tea trees are perennial crops, and the yield and quality of tea are closely related to the organic matter, total nitrogen, available N, P, and K in the soil where tea trees are planted. Organic fertilizer is a full-priced fertilizer with a variety of nutritional elements. The application of organic fertilizer in tea gardens can improve soil physical and chemical properties, balance soil nutrients, improve fertilizer utilization efficiency, and promote the growth of tea trees, thereby improving the yield and quality of tea. In addition to the base fertilizer, tea trees generally need topdressing, esp...
