Abstract

The invention discloses a novel biochar fertilizer and a preparation method thereof, and belongs to the field of biomass resource recovery and utilization, wherein the raw materials comprise, by weight, 60-80 parts of agricultural and forestry by-products, 20-30 parts of human and livestock manure, 15-25 parts of a catalyst, and 8-12 parts of an activator. According to the present invention, with the novel biochar fertilizer, the micro-pores can be substantially increased so as to increase the specific surface area, well increase soil organic matters, absorb heavy metals, improve soil and increase fertility, and the reservation of nutrients and the retention of the nutrients of agricultural and forestry by-products and human and livestock manure can be easily achieved so as to increase nutrition elements such as N, P and K and various trace elements and the like; and the preparation method is simple, controllable and easy-performing, has the industrialization promotion prospect, and has significant economic benefits, environmental benefits and social benefits.

Description

technical field [0001] The invention relates to the field of recycling and utilization of biomass resources, in particular to a novel biochar fertilizer 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-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-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...
