Abstract

The invention relates to a production method of a slow-release fertilizer and particularly relates to a synchronous slow-release humic acid fertilizer and a production method thereof. The synchronous slow-release humic acid fertilizer comprises the following raw materials in parts by weight: 36-42 parts of urea, 7-12 parts of monoammonium phosphate, 7-12 parts of potassium hydroxide, 26-32 parts of humic acid, 6-10 parts of sodium hydroxide and 0.5-3 parts of trace elements. By using the synchronous slow-release humic acid fertilizer, a slow-release effect synchronous with a fertilizer demand curve of crops is achieved, the quality of soil can also be improved, the stress resistance of the crops is improved, and the quality of a fruit is improved.

Description

technical field [0001] The invention relates to a production method of a slow-release fertilizer, in particular to a humic acid synchronous slow-release fertilizer and a production method thereof. Background technique [0002] Slow-release fertilizers are also called slow-release fertilizers or controlled-release fertilizers. The compounds containing nutrients in the fertilizers release slowly in the soil or the nutrient release speed can be controlled to a certain extent for the continuous absorption and utilization of crops. Humic acid and nitrogen, phosphorus, and Humic acid fertilizers made by combining potassium and other elements (for example: neutralizing humic acid with ammonia can be used to make ammonium humate fertilizers), which can increase fertilizer efficiency, improve soil, stimulate crop growth, and improve the quality of agricultural products. Traditional high-tower technology For the compound fertilizer produced, the utilization rate of nitrogen fertilizer...
