If intercropping with crops, it can be combined with crop weeding. Eucommia ulmoides young forest is closed, clearing the forest and ploughing once every summer to promote the growth of young trees. After Eucommia ulmoides becomes a forest, you can clear the forest once a year without ploughing. Before the beginning of winter, soil should be cultivated in the rhizosphere of young trees to protect against cold.
2. Topdressing:

Every spring is the peak growth period of Eucommia ulmoides. 1500 kg of barnyard manure and 50 kg of cake fertilizer are applied per mu, and radiant ditches are opened in the rhizosphere of the plant. During the vigorous growth period of Eucommia ulmoides in summer, the second topdressing was carried out. 2000 kg of barnyard manure, 50 kg of calcium superphosphate and 200 kg of plant ash were applied per mu. Phosphorus and potash fertilizer can also be used for extra-root topdressing. Irrigation and drainage: Eucommia ulmoides should be watered frequently after planting to keep the cave soil moist in order to survive. During the vigorous growth season in summer, it should be watered in time in case of drought, otherwise it will affect the growth of Eucommia ulmoides. In case of rainy season, stagnant water should be eliminated in time to prevent waterlogging.

The lateral branches of the lower part of the crown are properly cut off every winter to promote the thick and straight growth of the trunk and increase the dry bark yield. Cut off drooping branches, disease and insect branches and dead branches to make the crown ventilated and transparent. Combined with ramet propagation, the root tiller seedlings were separated from the mother plants and planted in the colonization site with roots to promote the healthy growth of the mother plants.
