In August, the climate is characterized by high temperature, rainy weather, and low sunshine. It is necessary to strengthen pest control and pay attention to drainage and pressure greening in the rainy season. Each green or grassy plant contains 50 to 100 kg of kanamycin and 1.0 to 2.0 kg of compound fertilizer or human excreta. When the young shoots of the young trees tend to stop in the middle of August, phosphorus and potassium fertilizers may be topdressed, and 0.1-0.2 kg of compound fertilizer may be applied. In the rainy season, excessive drainage and weeding of rain can break the tree trays and clear the drainage channels, so that the affected plants can be drained in time. The method is to open the rhizome, ventilate and air-dry the roots to restore the function of the root system as soon as possible. When it is clear after rain, timely cultivating and weeding, young plants can be deep plowed, the depth of about 20 to 30 cm, in order to grow roots and thoroughly remove weeds. This stage of pest control in the rainy season is a critical period for the prevention and treatment of peach borer pests. When the rate of egg fruit reaches 0.5% to 0.8%, spraying control is performed. The commonly used pharmaceuticals include 20% chlorbenzolid 2000 times, 20% cypermethrin 3,000 times, 40% aqueous methionine emulsion or 100 times. In mid-August, the insects were removed and buried deep. Spray Bordeaux multi-fluid or bacteriocin, special control of various leaf and fruit diseases.
