Abstract

The invention discloses a biomass coke compound fertilizer and a production method thereof, which belong to the technical field of fertilizers. The fertilizer is prepared from conventional chemical fertilizer and biomass coke and is granular, wherein the biomass coke accounts for 20 to 70 percent of the total mass of the fertilizer. The biomass coke is a solid product produced by a process of cracking a biological material (such as straws and the like) at the high temperature of between 300 and 700 DEG C under the anoxic condition, and has prominent characteristics of light texture and many pores. The compound fertilizer is conventional compound fertilizer containing N, P2O5 and K2O, and the content of the total nutrients is 15 to 30 percent. The production method for the biomass coke compound fertilizer comprises the following steps of: weighing the conventional chemical fertilizer according to different nutrient content and proportion, preparing the conventional chemical fertilizer into powder, adding biomass coke granules in a mass ratio, mixing the powder and the biomass coke granules uniformly, and performing granulation, collection and drying to form the granular biomass coke compound fertilizer. The biomass coke compound fertilizer has the advantages of rich raw materials, simple technology, good effect and the like, meanwhile, has certain carbon emission reduction capacity, and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to a biomass coke compound fertilizer and a production method thereof. Background technique [0002] Compared with single-element fertilizers, compound fertilizers have the advantages of many types of nutrients, high nutrient content, less auxiliary components, good physical properties, convenient storage and transportation, and labor-saving and time-saving advantages, and are very popular among farmers. In order to improve its fertilizer efficiency, people have invented many methods, such as granulation, film coating, adding adsorbents, mixed application with organic fertilizers, etc., but these measures have disadvantages of varying degrees, such as high cost, complicated technology, unstable effect, etc. . [0003] Biomass char is the condensation product of biological materials under high temperature and anoxic conditions. It has a huge specific surface area and strong surfac...
