Abstract

The invention relates to a preparation method of a biomass carbon fertilizer, which comprises the following three steps of: 1) air-drying and crushing a biomass raw material; 2) putting the biomass raw material obtained in the step 1) into modifier solution with a concentration of 1-10 percent to soak for 8-24 hours, and drying at a temperature of 80-100 DEG C; and 3) pre-oxidizing the biomass raw material dried in the step 2) in a box type furnace for 0.5-2 hours at a temperature of 245 DEG C, then carbonizing for 0.5-4 hours at a temperature of 250-650 DEG C and under the anoxic and anaerobic conditions, grinding and sieving with a 10-100-mesh sieve to prepare the biomass carbon fertilizer. A use method of the biomass carbon fertilizer comprises the following three steps of: 1, applying the prepared biomass carbon fertilizer in farmland soil according to the 100-1000 kilograms / hectare; 2, ploughing 0-30 centimeters of soil on a surface layer in the fertilized farmland soil, so that the biomass carbon fertilizer is uniformly mixed with the soil; and 3, planting crops in the soil applied with the biomass carbon fertilizer to obtain a higher-quality crop product.

Description

technical field [0001] The invention relates to a preparation and use method of a biomass carbon fertilizer, which is related to the preparation and use of a biomass carbon fertilizer for agricultural soil improvement, and belongs to the technical field of chemical fertilizer manufacturing. Background technique [0002] Straw usually refers to the remaining part of wheat, rice, corn, potato, oilseed, cotton, sugarcane and other crops after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in organic matter and nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and other nutrients, and is a renewable biological resource with multiple uses. As a large agricultural country, our country is rich in straw resources. The annual crop straw resources account for nearly half of my country's biomass energy resources. The traditional methods of dealing with straw in rural areas make a considerable part of the straw reso...
