Alder fungus grows black fungus. The nutrients and water required for the growth and development of black fungus come from auricularia. Therefore, timely tree cutting is important to improve the quality of auricularia. China's territory is vast, the climate varies widely, the vegetation is complex, and there are many types of trees. The time for cutting trees cannot be unified. Generally speaking, when the leaves of the ear tree turn yellow until the ear tree is about to germinate, it is the proper time to cut the tree. Ear farmers call it "leaf yellow tree". During this period, the nutrient stored in the trunk is the most abundant, the leaves do not flow fast, the bark and xylem are tightly combined, and it is not easy to fall off when moving. In addition, if the method of cutting trees is proper, "leaving trees with yellow leaves" is also conducive to germination and regeneration of the remaining tree stumps (such as oaks) to maintain ecological balance. The cultivation of alder in shiitake mushrooms and Tremella fuciformis also requires "leaf cutting trees".
