(1) Replenish water and moisturize in time: check the moisture every 10 ~ 15 days. If the water is insufficient, uncover half of the plastic film and irrigate it to keep it alive. At the same time, spraying 1 ~ 2 times of 1.8% sodium nitrate or seaweed nutrient solution after planting can promote callus formation and root growth, and improve the survival rate of seedlings.

(2) Fixing the stem: before germination, fixing the stem at a height of 25-40 cm above the joint according to the seedling thickness. It is required that there must be 3-5 full buds under the incision. After the stem is fixed, it can reduce water evaporation, promote short branches and prevent "demoulding"

(3) Bud removal: After the seedlings survive and germinate, the buds below the mating interface should be erased at any time, and the extra buds left on the seedlings as planned should also be erased, which is beneficial to the growth of new shoots and the expansion of crown.
