How to correctly use chemical agents to promote crop growth

The chemical immersion promotion method is a horticultural technique that uses chemical agents to induce mutations in genetic material, also known as chemical mutation induction. Take out the orchid plants that need variegation promotion, wash them clean, and after drying, immerse the roots and pseudobulbs in a 1000-fold dilution of the Japanese-made variegation promoter "Yililing" for 15 minutes, then remove and replant. Spray the diluted solution on the leaf surfaces and undersides once a week, for more than 10 consecutive times. After this treatment, those with the potential to produce line variegation can have the variegation process accelerated; for those that already have line variegation, it can not only make the line variegation brighter, but also make the variegation traits more evolved, and can also make the flower colors more brilliant, or make the flowers also have corresponding line variegation.
