Liquid fertilizer containing humic acid

Abstract

The invention discloses a liquid fertilizer containing humic acid. The liquid fertilizer comprises a liquid raw material A which has the pH of 7.0-7.5 and contains soluble organic matters or humic acid, a raw material B containing urea, potassium dihydrogen phosphate, potassium sulfate or potassium chloride, and an anion type polyacrylamide raw material C which is completely dissolved with water to form a jelly and has the pH of 7.0-7.5; the component B is added into the component A and is stirred to be dissolved; then the pH value is adjusted to 7.0-7.5 by ammonia water; then the component C is added and is mixed uniformly; and the water is added until the volume is one cubic meter. The liquid fertilizer has the functions of folding water and fertilizer and also has the function of loosening soil; the liquid fertilizer is convenient to use and is suitable for a pipeline; the liquid fertilizer can provide one more treatment measure for waste liquid treatment of food factories and the wastes are changed into valuable things; a production process is simple and the source of the raw materials is convenient; the utilization rate of the fertilizer is high and the costs of the fertilizer and the manpower are reduced; and after the fertilizer is applied, crops have high yield, good quality and good taste.

Description

【Technical Field】 [0001] The invention relates to a liquid fertilizer containing humic acid, which belongs to the technical field of chemical fertilizers. 【Background technique】 [0002] Liquid fertilizer can be divided into two types: solid and liquid. They are finally dissolved in liquid and adjusted to a certain concentration before use. It is indeed economical when combined with modern irrigation equipment such as drip irrigation and spraying. Although the current liquid fertilizer is easy to use and effective, but the fertilizer nutrient loss is also large, causing excessive waste, lack of functional diversity, and no function of retaining water, fertilizer, and soil. How to change this In the current situation, many technicians have made improvements in market operation. [0003] For the irrigation and use of fertilizer, if the water retention function can be achieved, then the irrigation will be relatively reduced, which can directly reduce the waste of fertilizer. If the n...

Problems solved by technology

[0004] Humic acid-containing liquid fertilizer has been a mature product after a long period of market operation, but it is insufficient in terms of function enhancement, and the functional diversity has not been highlighted. If it is combined with other fertilizers such as chemical fertilizers Taking it into consideration and improving it will be a good research direction and will also achieve good application results
