Optimal Combinations of Plant Growth Regulators and Water-Soluble Fertilizers
1.Diethyl aminoethyl hexanoate(DA-6) + Macronutrient Water-Soluble Fertilizer:
Fertigate with 10–15g of 98% DA-6 technical powder per mu (approx. 667 m²) combined with a balanced or high-potassium water-soluble fertilizer. Leaves turn a deep green within 3–5 days, with effects lasting over 20 days; the combination remains effective even in low temperatures, significantly enhancing root development and the rate of fruit expansion.
2. Brassinosteroid + Amino Acid Water-Soluble Fertilizer:
Foliar spray using a 1,500-fold dilution of 0.01% brassinosteroid combined with an 800-fold dilution of amino acid water-soluble fertilizer. This rapidly replenishes small-molecule organic nitrogen and trace elements while comprehensively activating the crop's drought, cold, and salinity-alkalinity resistance; it is particularly effective for post-disaster recovery and strengthening seedlings.
3. Sodium Nitrophenolate(Atonik) + Humic Acid Water-Soluble Fertilizer:
Fertigate with sodium nitrophenolate combined with humic acid water-soluble fertilizer to rapidly overcome crop stunting and yellowing. It simultaneously improves the rhizosphere soil environment and promotes the proliferation of fine root hairs, allowing weak or aging seedlings to recover twice as fast compared to using humic acid fertilizer alone.
4. Indole-3-butyric Acid (IBA) + High-Phosphorus Water-Soluble Fertilizer:
Apply a rooting regulator combined with high-phosphorus water-soluble fertilizer via root drenching. This doubles the effect of new root promotion, enabling crops affected by waterlogging or transplanting to produce abundant white roots within 7 days and significantly reducing seedling mortality.
