Problems solved by technology

[0005] At present, most of the water-soluble fertilizers on the market are mixed with simple ingredients, or added with humic acid. There is no water-soluble fertilizer prepared by combining amino acids with humic acid, and the preparation of solid water-soluble fertilizer has poor solubility and is easy to agglomerate, which greatly reduces the water-soluble fertilizer. effective utilization of

Abstract

The invention belongs to the technical field of crops fertilizer, and particularly relates to a water-soluble fertilizer for planting yam. The water-soluble fertilizer is prepared from, by weight, humic acid extracting solution, composite amino acid extracting solution, ammonium nitrogen, water-soluble phosphorus, water-soluble potassium, urea nitrogen, nitrate nitrogen, iron vitriol, water-soluble magnesium, zinc sulphate, manganese oxide, chelating agent, and blue copperas. The fertilizer takes waste leather as raw material; through technical screening, the best technique for producing composite amino acid extracting fluid is acquired, thus the content of the amino acid is up to 20.00%, the pH value of the product is 5-7, the insoluble matter content in the water is 0.15%, and the maximum dissolving amount in 100ml water is up to 57.5g. Therefore, the product safety and stability are greatly guaranteed.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, and in particular relates to a water-soluble fertilizer for planting yams and a preparation method thereof. Background technique [0002] my country is a large agricultural country with a large population. In order to increase food production, one of the effective means is to use fertilization. At present, fertilization in the world is mainly based on chemical fertilizers. However, due to long-term excessive or unreasonable application of chemical fertilizers, the proportion of nutrients in the soil is out of balance, resulting in soil compaction, reducing the utilization rate of fertilizers and the quality of agricultural products, and the use of chemical fertilizers Production and application will cause air and water pollution, causing great damage to the environment. [0003] Humic acid is a macromolecular organic substance that exists widely in nature. The basic structure is an arom...
