1. Biodiversity provides natural enemies and natural enemy resources: A variety of plants, insects and other organisms in the tea garden ecosystem provide a large number of natural enemies and natural enemy resources for tea trees. For example, some natural enemies of insects such as ladybugs and parasitic bees can control pests in tea gardens. They feed on pests and help tea plants resist pests by controlling the number of pests and spreading germs. In addition, some herbivorous insects also play a role in controlling weeds and ensuring the growth space and nutrients of tea trees.
2. Biodiversity provides ecological balance: biodiversity in tea garden ecosystem helps to maintain a relatively stable ecological balance. There are complex interactions between different organisms, which can regulate the number of pests and weeds to some extent. For example, some beneficial insects can directly prey on pests, and some herbivorous insects like to choose certain weeds as food, which helps to reduce the number of pests and weeds, thus reducing the harm of pests and weeds to tea trees.
Therefore, protecting and improving the biodiversity of tea garden ecosystem is one of the important strategies to control tea pests and weeds. By increasing plant diversity and avoiding excessive use of pesticides, the level of biodiversity can be improved, so as to better control the occurrence of tea diseases, pests and weeds.
