Liquid fertilizer containing amino acids, zinc and selenium, and preparation method of liquid fertilizer

Abstract

The invention belongs to the field of agricultural fertilizer, and in particular relates to liquid fertilizer containing amino acids, zinc and selenium, and a preparation method of the liquid fertilizer. The liquid fertilizer is easily absorbed by crops, the quality of agricultural products is greatly improved, and conditions for producing functional foods are achieved. The liquid fertilizer containing the amino acids, the zinc and the selenium is prepared from the following components: more than or equal to 120-150g / L of the amino acids, more than or equal to 12g / L of zinc element and more than or equal to 80-100g / L of the selenium; the liquid fertilizer is prepared by the certain preparation method.

Description

1. Technical field [0001] The invention belongs to the field of agricultural fertilizers, in particular to a liquid fertilizer containing amino acid zinc and selenium and a preparation method thereof. 2. Background technology: [0002] At present, the chemical industry has solved the problem of food and clothing. However, the production and application of various fertilizers have been increasing, which has played an important role in promoting the development of agricultural production. However, with the continuous increase in the amount of chemical fertilizer application, the shortcomings of its application have become increasingly prominent, mainly in the following aspects: [0003] 1. Increased fertilization cost due to high input and low output. At present, the utilization rate of nitrogen fertilizer in my country's chemical fertilizer field is only 15-40%, the utilization rate of phosphorus fertilizer is only 10-20%, and the utilization rate of potassium fertilizer is ...

AI Technical Summary

Problems solved by technology

[0004] 2. Poor environmental protection, resulting in serious soil compaction

Excessive use of chemical fertilizers will deteriorate the physical and chemical properties of the soil, block the soil voids, destroy the soil aggregate structure, and cause the imbalance of soil nutrients, compaction, pollution and decline in fertility

At the same time, excessive application of chemical fertilizers can also lead to groundwater pollution and air pollution, which is also a threat to human health.

[0005] 3. The low quality of crops directly threatens the safety of human life

[0006] The quality of crops currently produced is unsatisfactory, pesticide residues exceed the standard, chemical fertilizers are excessively applied and the utilization rate is low, vegetable nitrate accumulation is serious, heavy metal pollution, pathogenic microorganism pollution, etc. occur from time to time, which have become serious obstacles restricting crop production.
