Liquid fertilizer production method

Abstract

The invention belongs to the technical field of agriculture and particularly relates to a fertilizer production method. According to the liquid fertilizer production method provided by the invention,a manner of extracting biomass charcoal by adopting wood vinegar is innovatively adopted, and the purification and nutrient enrichment process of the wood vinegar is completed in one step. By utilizing the biomass charcoal, suspended solids, tar, unstable materials and the like in the wood vinegar can be adsorbed, and the chromaticity of the wood vinegar is reduced. More remarkably, when the biomass charcoal is directly extracted by utilizing the wood vinegar, small molecular weight water-soluble organic aromatics and other substances favorable for plant growth in the biomass charcoal can be extracted, soluble humic acid composition in the wood vinegar is improved, and enrichment of nutrients in the wood vinegar is reached.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a fertilizer production method. Background technique [0002] How to efficiently utilize agricultural waste has always been a research hotspot in agricultural technology. Taking straw as an example, the earliest way to utilize straw is to return it to the field. There are two traditional methods of returning straw to the field, namely crushing the straw and returning it directly to the field, and burning the straw on the spot to make plant ash and then returning it to the field. However, direct smashing of straw and returning it to the field will easily lead to problems of diseases and insect pests; and burning the straw on the spot and returning it to the field will not cause problems of diseases and insect pests, but open-air burning will cause waste of organic matter in the straw, and a large amount of thick smoke will be generated during the burning process. ...
