2. Fruit tree growth: before the fruit trees bloom, spray fruit-setting agents to improve the fruit-setting rate and increase fruit tree yield; one week after the flowers fall, spray pesticides to prevent pests and diseases and reduce the possibility of their occurrence; during the fruit enlargement period, spray Zhuangguodiling once, which can thicken the fruit stalk a little and also increase the amount of nutrients transported.
Characteristics of pests and diseases: for example, to control whiteflies (which fly away at the slightest touch), spray in the morning when the dew has not yet dried; to control flower thrips, spray in the morning when the flowers open; to control leaf thrips, spray in the evening or at night, etc. Diseases usually spread through rainwater.
