Humic acid sodium: After soaking the roots with 0.5% humic acid solution for 12 hours, use 0.8% water-retaining agent to root the roots; or use 1 gram of sodium humate and 1 gram of water-retaining agent to add 1 kg of water and mix in appropriate amount of yellow. The mud is muddy and afforested. This law applies to broad-leaved forests. 5. Rooting powder: Soak the roots with a solution with a rooting powder concentration of 50 mg/kg~80 mg/kg for 0.5 to 1 hour. The survival rate after planting can reach 95%~98%.
