Low-volume spraying technology means that the application amount per unit area is constant, and the pesticide solution is slightly diluted, and the water consumption is equivalent to 1/5-1/10 of the conventional spray technology. This technology improves operational efficiency and is widely used in greenhouses and mountain areas. Electrostatic spray technology through the high-voltage static electricity generating device, so that spray droplets with the method of spraying, liquid droplets deposited on the surface of the leaf significantly increased the amount of pesticides can be effective utilization increased to 90%. Pelletizing application technology For the water-soluble pesticides used in paddy field, the pelletized pesticide application technology can be adopted. The pellets can be spread evenly in the farmland, and the work efficiency is improved by more than ten times without pesticide drift and pollution. Adjacent crops. The recirculation spray technology re-engineers the conventional sprayer equipment. A drug recovery device is installed on the opposite side of the sprayer. The drug solution that has not been deposited on the target plant is collected and then pumped back to the drug tank for recycling. The pesticide is greatly improved. Effective utilization. The drug roller coating technology is mainly used for the use of systemic herbicides. The drug solution seeps through the drug roller (a wiper roller made of a foam material capable of absorbing the drug solution) and leaks from the surface of the drug roller. The upper leaves of the grass can work. This method can almost completely apply the agent on the surface of the target plant, and no spillage or dripping of the solution occurs. The use of computer technology The United States has used computer control systems for orchard sprayers. The system uses ultrasonic sensors to determine the status of fruit trees. The computer control system automatically adjusts pesticide spray characteristics based on changes in the shape of fruit trees. This technology greatly improves the effective utilization of pesticides and represents the direction of the use of pesticides. The above technologies can greatly reduce the amount of pesticides, and can save 50%-95% of pesticides, and can significantly reduce or substantially eliminate the possibility of pesticide spraying on non-target plants, thereby significantly reducing environmental pollution.
