Abstract

The invention relates to a chelated trace element organic fertilizer and a production method thereof. The production method comprises preparing raw materials, preparing a chelated trace element solution, preparing a borax solution, preparing a spray agent, pelletizing, drying and sieving. Due to the adoption of the chelated trace element organic fertilizer, trace elements generally lacked in soil in China are replenished specifically, and the trace elements have high effectiveness. Weathered coal humic acid can be used for improving soil culture fertility, enhancing the product quality, and improving the stress tolerance such as drought resistance, cold resistance, salinity tolerance and the like of crops. The method disclosed by the invention has the characteristics of simple production technical process, wide raw material source, easiness for operating, low cost and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizers. More specifically, the present invention relates to a chelated trace element organic fertilizer, and also relates to a production method of the chelated trace element organic fertilizer. 【Background technique】 [0002] Traditional organic fertilizers are produced from livestock and poultry manure and crop stalks. Since the mid-1980s, Western developed countries such as the United States, Japan, and Australia have begun to pay attention to the research and application of organic fertilizers. Most of the organic fertilizer production in Western European countries mainly deals with municipal solid waste and animal manure, adding agricultural and sideline product waste such as straw, bagasse, and even sawdust to facilitate fermentation, and rarely uses pure plant materials. They mainly research the technology of industrialized treatment of livestock and poultry manure, including rapid fermenta...
