Pay attention to fertilization and pest control in summer tea gardens

Prevention and control of pests and diseases In July, tea garden pests mainly include false green leafhopper, black thorn powder, wax mites and tea mites, which should be prevented early. Wax mites, black thorn mites, and false green leaf mites are all sucking pests. The method of administration is similar. The pollution-free tea garden can be controlled by phoxim, imidacloprid and acetamiprid. In the organic tea garden, the false green leaf green leaf can be picked in batches. When the temperature is suitable, it can be controlled with Beauveria bassiana. The white fungus preparation, rotenone and matrine can be used to control black thorn. For the prevention and control of tea mites, the pollution-free tea garden uses bifenthrin, cypermethrin, deltamethrin, diflubenzuron, etc. The organic tea garden uses light to trap adult worms, and can also spray rotenone and matrine.

Fertilization This year, the drought lasted for a long time, and the tea garden lacked water and lacked fertilizer, which caused the new shoots of tea trees to be significantly shorter than in previous years. In recent days, the rainfall is concentrated and the rainfall is large. After the fertilizer is applied, it is easily drained by the rainwater. The rainwater should be fertilized according to the weather forecast and the rain garden should be applied a small amount until the plum is released. Pay attention to temperature changes to prevent improper rooting and burning of leaves.
