(2) seed soaking

Seed elutriation-impurity removal-soaking in warm water at 55℃/soaking in clean water at 20-30℃ for 0/0 min 12 hr-draining.

(3) accelerating germination

Scatter the soaked seeds evenly in the seedling tray with cultivation substrate at the bottom, and sow about 800g per square meter. 20 ~ 25℃, accelerate germination, pay attention to moisturizing, and germinate for 2 ~ 3 days. Keep the environment and breeding facilities clean and pollution-free.

(4) culture

After 3 days, put the seedling tray on the cultivation rack and see the light. The temperature is 20 ~ 25℃, spraying water 3 ~ 4 times a day, and harvesting for 8 ~ 10 days.

(5) Harvest

Cotyledons are completely expanded, plant height 10 cm, buds are green, and hypocotyls are turquoise. Pull up the sprouts together with the substrate, then cut off the roots and substrate with scissors, which can be packaged and sold in plastic bags or fast food boxes.
