AI Technical Summary
Technical Problem
Existing chemical agricultural fertilizers lead to pesticide residues, soil and environmental pollution, and the use of nitrogen fertilizers leads to excessive nitrates and nitrites, threatening health and the environment.
Method used
The compound liquid fertilizer process is adopted, including the proportion of compound amino acid powder, chitosan, carotenoids, ascorbic acid and potassium sorbate. By degrading chitosan and mixing the finished product, it is sterilized and packaged to form a safe liquid fertilizer.
Benefits of technology
Enhance crop disease resistance, increase yield and quality, reduce environmental pollution, and adjust disease resistance and stress resistance.
