Clear Garden time The best time for clearing the garden was performed twice before germination and during the inflorescence separation period. At this time, all kinds of diseases and insect pests began to gnaw and reproduce. The eggs of the diseased eggs were exposed on the branches, and the trees were not covered. The medicinal liquids could directly contact the eggs of the diseases and insects, and the control effect was good. The objects to be controlled in the Qingyuan Garden include pear lice eggs, ball worms, rot disease, and black spot disease.
