AI Technical Summary
Current laver farming suffers from problems such as low fertilization efficiency, severe nutrient loss, and difficulty in precise nutrient supply. Traditional soaking and spraying methods cannot meet the demand for large-scale, high-efficiency laver yield increases.
During the drying and dewy period of laver, drone spraying technology is used in combination with diluted humic acid solution and phosphorus nutrient solution. The pretreatment of wetting activates the cell absorption channels, enabling precise fertilization and avoiding dilution and waste of nutrient solution.
It enables large-scale, labor-saving, and efficient fertilization, significantly improving the yield and quality of seaweed, reducing labor costs, and increasing fertilizer utilization.
