Abstract

The invention discloses a biological carbon organic fertilizer and a preparation method thereof. The biological carbon organic fertilizer comprises, by weight, 32.12%-34.60% of biological carbon, 62.83%-64.12% of organic matter and 2.28%-5.05% of trace elements, and preferably biological carbon produced form flue-cured tobacco stalk. According to the invention, characteristics of the biological carbon prepared from flue-cured tobacco stalk are fully utilized to produce a novel fertilizer with a variety of effects, so as to increase the utilization rate of fertilizer, and improve the absorption and utilization of trace elements by crops. A reasonable and scientific approach for utilization of tobacco stalk is also provided to reduce the environmental pressure of planting area, has good economic benefit, social benefit and ecological benefit, and can enhance the yield and quality of crops.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a compound fertilizer. Background technique [0002] Fertilizer type, fertilization amount and ratio have a great impact on the yield and quality of food crops or economic crops. At present, the fertilizer application of food crops or economic crops in my country is unbalanced. The traditional organic and inorganic fertilizer formulations have relatively single ingredients and nutrients. They simply mix several organic substances and inorganic fertilizers, and rarely consider adding trace elements, so they cannot meet the needs of crop growth, and have little impact on the restoration of soil fertility and structural improvement. Small. [0003] Biomass carbon is a kind of highly aromatic substance obtained by carbonization and pyrolysis of biomass under anoxic or anaerobic conditions. It is translated as Biochar in China. Commonly used descriptors include biochar, biochar and biomass coke. It ...
