Use rooting regulators during seedling cultivation to develop robust root systems and significantly boost transplant survival rates

The scientific use of rooting regulators during the seedling stage effectively promotes root development and significantly boosts post-transplant survival rates, serving as a practical method to enhance quality and efficiency in seedling production.

I. Key Functions of Rooting Regulators in Seedling Production
Promotes New Root Growth: Key ingredients such as Indole-3-butyric acid (IBA) and Naphthaleneacetic acid (NAA) rapidly induce the formation of abundant fine roots and thicken the taproot, increasing total root mass by over 30%.

Accelerates Recovery: Seedling roots adapt quickly to the new soil environment after transplanting, cutting the recovery period by more than half and preventing issues like weak or stunted seedlings caused by prolonged recovery times.

Reduces Seedling Mortality:A well-developed root system significantly enhances stress resistance; mortality rates due to adverse conditions—such as drought or low temperatures—drop markedly, raising survival rates to over 90%.

II. Proper Application Methods During the Seedling Stage
Seedbed Soil Mixing: Dilute 500ml of rooting agent 10–20 times and mix it evenly into 50kg of potting soil or the soil of a 4–5 m² seedbed; sow seeds directly afterward to ensure uniform emergence without weak seedlings.

Seedling Stage Drenching:Once seedlings reach the "two-leaf, one-heart" stage, apply a 300-fold dilution of the rooting agent (5–10kg of solution per square meter of seedbed) to promote taproot elongation and thickening, as well as the proliferation of lateral roots.

Root Dipping Before Transplanting:Dip seedling roots into a 500-fold dilution of the rooting agent before planting; this directly stimulates rapid root growth after transplanting and significantly improves survival rates.
