Problems solved by technology

At present, tea farmers generally use chemical pesticides to prevent and control tea plant diseases and insect pests. Long-term and unreasonable use of chemical pesticides will not only destroy the ecological environment of tea gardens, cause excessive pesticide residues in tea, but also make the control of pests stronger and stronger, forming a problem in prevention and control. Vicious cycle; moreover, the tea fertilizers currently used by tea farmers generally only have the effect of promoting the growth of tea leaves, and do not have the effect of preventing pests and diseases
