Abstract

The invention discloses a biological activated carbon fertilizer for reducing nutrient loss. The biological activated carbon fertilizer is prepared from the following materials in parts by weight: 60-80 parts of biological activated carbon, 20-40 parts of a compound fertilizer, 10-20 parts of fermentation liquor, and 15-25 parts of an additive. The biological activated carbon fertilizer takes a crop straw as a material component, the used crop straw is low in cost and easy to get, is subjected to dehydration and deoxygenation, and is crushed into a biological activated carbon powder through a high temperature carbonization method, the carbonization effect is good, the carbon content is more than 25%, the carbonization rate of the straw is effectively improved, the rate of a finished product of the carbon fertilizer is high, the application effect is good, a heavy metal in the soil is passivated, and the activity of microorganisms in the soil is improved. The biological activated carbon fertilizer has a larger specific surface area, and the content of organic matters in the soil is increased; as a low-cost non-chemical fertilizer, the product guarantees the yield in organic agriculture and green agriculture, and a preparation method is simple, controllable and easy to implement.

Description

technical field [0001] The invention relates to the fields of high-value comprehensive utilization of biomass resources and environmental pollution control, in particular to a biochar fertilizer for reducing nutrient loss. 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 e...
