Abstract

The invention discloses a molybdenum-modified charcoal fertilizer. The molybdenum-modified charcoal fertilizer is prepared from, by weight, 70-80 parts of agriculture and forestry byproducts, 30-40 parts of human and animal excreta, 10-20 parts of an additive and 10-20 parts of an activating agent. According to the molybdenum-modified charcoal fertilizer, charcoal has a large specific surface area, and the content of organic substances of soil is improved; human and animal excreta and agriculture and forestry byproducts serve as the main raw materials, and the molybdenum-modified charcoal fertilizer contains richer nitrogen, phosphate, potassium and microelements compared with charcoal fertilizer obtained by only using agriculture and forestry byproducts as the raw material. As low-cost non-chemical fertilizer, the product can guarantee the yield of organic agriculture and green agriculture, a preparing method is simple, controllable and easy to implement, the molybdenum-modified charcoal fertilizer has higher adsorption performance and higher fertilizer efficiency compared with traditional charcoal fertilizer while human and animal excreta and biomass are effectively treated, and the molybdenum-modified charcoal fertilizer can replace chemical fertilizer to be applied within a certain range and has industrial popularization prospects and remarkable economic benefits, environmental benefits and social benefits.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a molybdenum modified 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 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 compaction. ...
