Abstract

The invention discloses a biomass compound fertilizer, which consists of the following effective components in parts by weight: 14-15 parts of nitrogen, 4-6 parts of phosphorus pentoxide, 4-6 parts of potassium oxide and 10-20 parts of biomass, wherein the biomass is prepared from biomass by treating under an anoxic condition at 350-500 DEG C for 30-60 seconds. The invention additionally discloses a preparation method for the biomass compound fertilizer. The preparation method has the advantages that preparation process is simple, the cost is low and the method is suitable for mass production. By applying the biomass compound fertilizer disclosed by the invention, the soil structure can be improved and the utilization ratio of the effective components is improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a biomass compound fertilizer and a preparation method thereof. Background technique [0002] The use of chemical fertilizers is helpful to the growth of crops, but long-term application of chemical fertilizers will cause soil compaction, reduce aeration, affect crop growth, and reduce fertilizer utilization. Biomass fuel is used as a fuel and a renewable energy source. The biomass produced after combustion contains the nutrients needed for plant growth. However, due to the fluffy biomass, it is inconvenient to transport and apply, and has not been fully utilized. Contents of the invention [0003] In view of this, one of the purposes of the present invention is to provide a kind of biomass compound fertilizer, which is convenient for transportation by adding biomass to chemical fertilizers, and can improve soil structure after application, improve the utilization efficiency of the ...
