Problems solved by technology

Although biochar can be used as a fertilizer, it has less microporous structure, lower specific surface area, and retains less nutrients including trace elements, so it is generally necessary to add other fertilizers when using it

Abstract

The invention provides a biochar fertilizer with high calcium content. The biochar fertilizer is prepared from the following raw materials by weight: 70 to 90 parts of a biomass raw material, 30 to 40 parts of human and animal manure and 20 to 30 parts of an additive. According to the invention, biochar has a great specific surface area and increases the content of organic matters in soil; since a mixture of the human and animal manure and biomass is used as a main raw material, the fertilizer is richer in nitrogen, phosphorus, potassium and trace elements compared with biochar fertilizer only prepared from biomass; as low-cost non-chemical fertilizer, the biochar fertilizer with high calcium content can guarantee the output of organic agriculture and green agriculture; the preparation method is simple, controllable and easy to apply; and the biochar fertilizer provided by the invention effective treats biomass and human and animal manure, has higher adsorption performance and fertilizer efficiency compared with traditional biochar fertilizer, can replace chemical fertilizer in a certain extent, and has industrial promotion prospect and substantial economic benefits, environmental benefits and social benefits.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a biochar fertilizer with high calcium content and a preparation method thereof. Background technique [0002] No matter in the fields of food crops or commercial crops, fertilization has been used for a long time to improve crop yield and quality. From the earliest application of farm organic fertilizers to the application of inorganic fertilizers, and then to the application of organic and inorganic compound fertilizers. Fertilizer type, fertilization amount and ratio have a great impact on the yield and quality of food crops or economic crops. Although traditional fertilizers, especially organic and inorganic compound fertilizers, have played a good role in increasing crop yields. However, traditional fertilizers have an unreasonable ratio of ingredients and nutrients, which can hardly restore soil fertility, improve soil structure, and even cause side effects, such as soil compactio...
