One, windy and rainy days should not take skin: windy weather, dry climate, eucommia trees, a large number of water evaporation, then take skin cells easy to die. On rainy days, the rain flushes the trunk directly. After the cells are immersed in water, they are prone to necrosis and difficult to re-split. Second, dry days should not be skin: Because the drought supply of eucommia tree water supply is insufficient, the roots from the soil to absorb the water and inorganic salts and other nutrients decreased, growth is not strong, reduced viability, skin and xylem is not easy to separate. Third, weak trees, saplings, old trees should not be skin: Because such trees do not grow vigorously, photosynthesis capacity is reduced, the organization is not well-developed, the nutrients absorbed can not meet their own needs, in case of trauma will die. Fourth, after rain or watering should not immediately take skin: need to stop 2 days before the skin. Due to the rain, the roots are absorbing and transporting water in large amounts, and the tissues in the plants are storing nutrients. Premature skin removal caused the dehydration of the trees by cutting off the tissue and causing the water and nutrients being transported to flow out of the rupture ducts.
