When girdling Eucommia ulmoides, note the following points:
1. Girdling time. Generally, it should be carried out when the temperature is 25-30°C and the relative air humidity is 70-90%.
2. Choose Eucommia ulmoides trees that have grown for more than 10 years and are vigorous in growth (weak or poorly growing trees are not suitable for girdling) for girdling. Make the cut more than 30 cm above the ground, and the girdling length generally must not exceed 100 cm.
3. When girdling, never damage the tree's cambium.
4. Avoid peeling bark on rainy days, otherwise the wound will not heal for a long time and will become moldy, unable to form new bark, affecting bark regeneration. It is best to choose cloudy weather without rain.
5. Take protective measures for the peeled area, avoid exposure to scorching sun and rain washout, and prevent mechanical damage and touching with hands.
