In agricultural production, the use of pesticides is indispensable, but the application of pesticides can be improved to reduce the amount of pesticides used to achieve the full use of pesticides and reduce the pollution of pesticides. The following technologies can significantly reduce the amount of pesticides used, can save 50% to 95% of pesticides, and significantly reduce or substantially eliminate the possibility of pesticide spraying on non-target plants.
Pellet application
For water-soluble pesticides used in paddy fields, pelletized pesticide application techniques can be used. The pellets can be spread evenly on the farmland, and the work efficiency can be increased by more than ten times. There is no drift of pesticides and no pollution to neighboring crops.
Recycling spray
The conventional sprayer equipment was redesigned and reconstructed. A drug recovery device was installed on the opposite side of the sprayer. The liquids collected on target plants that had not been deposited were pumped back to the liquid tank for recycling, which could significantly increase the effective use of pesticides. rate.
Low spray
The application amount on the unit area is constant, and the pesticide solution is slightly diluted, and the water consumption is equivalent to 1/5 to 1/10 of the conventional spray technology. This technology improves operational efficiency and is widely used in greenhouses and mountain areas.
Electrostatic spray
Through the electrostatic high-voltage generating device, the droplet sprayed on the method of spraying, the amount of liquid droplets deposited on the surface of the blade significantly increased, the effective utilization of pesticides can be increased to 90%.
Drug roller application
It is mainly used for the absorption of herbicides. The medicinal liquid seeps out from the surface of the medicine roll through the medicine roll (a kind of wiper made of foam material that can absorb the liquid medicine), and only needs to contact the leaf on the upper part of the weeds. It will 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 pesticides will inevitably lead to certain residues. Saving pesticide use will minimize this problem. This is an effective method.
