AI Technical Summary

Technical Problem

Existing hydroponic cultivation methods face inefficiencies in nutrient and water use due to excessive root system development, leading to unnecessary resource consumption and potential environmental pollution from fertilizer runoff.

Method used

A method for hydroponic cultivation that involves reducing the root mass of plants by cutting or treating the roots, followed by cultivating the plants in a nutrient solution to balance above-ground and below-ground tissue ratios, utilizing solid culture media like urethane, and adjusting nutrient solutions for optimal growth.

Benefits of technology

This approach enhances nutrient utilization efficiency and reduces resource requirements while maintaining above-ground plant productivity, as demonstrated by improved dry weight ratios and reduced underground tissue.
