How to prevent pests from pollution-free tea?

How to prevent pests from pollution-free tea? Please guide the methods of non-pollution pest control of tea: first, intercropping other tree species in the remaining corner of the slope around the tea garden, properly planting some trees such as ginkgo biloba and persimmon (planting Eucalyptus grandis is strictly forbidden), improve the microclimate of the tea garden, increase biodiversity, and reduce the occurrence of tea plant diseases and pests. Plant about 15 trees per mu, no more than 20. Second, the installation of solar energy insecticidal lights make use of the phototaxis of pests, install solar energy insecticidal lamps to trap and kill the adults of tea pests such as tea inchworm and tea caterpillar, and reduce the number of eggs to reduce the base number of pests. A solar energy insecticidal lamp can prevent and control about 50 mu of tea garden pests. Third, the yellow armyworm board is inserted into 20 yellow armyworm boards per mu to attract adults of winged aphids, black whitefly and scale insects, small green leafhoppers and other pests. The lower edge of the yellow board should be about 10 cm higher than the tea canopy surface, and the board surface is perpendicular to the sidewalk. Fourth, release predatory mites in the tea garden, release predatory mites to feed on harmful mites, and control the damage. 15 days before the predator mites were released, the base number of harmful mites was reduced by spraying eco-environmental pesticides, and 20 bags of predator mites were put per mu, cut open and hung under the cover of tea trees. After releasing mites, insecticides and acaricides are no longer used. Fifth, use sex attractant traps to trap and kill adults of tea inchworm, tea caterpillar, tea caterpillar and other tea pests. Each set of sex attractants was used to control pests in 1 mu of tea garden. Click to get more tea planting techniques click to get more flower planting techniques
