Zero growth of pesticides is the direction of future development. Finding ways to improve the utilization rate of pesticides is the most direct solution. Generally, the following principles should be followed when using pesticides:
Pelletizing application
For the water-soluble agent used in paddy fields, the pelletized application technique can be used. The pellet can be evenly spread in the farmland, the work efficiency is increased by a factor of ten, and there is no pesticide drift and no pollution to adjacent crops.
Circulating spray
Redesign and renovate the conventional spray equipment, install a drug recovery device on the opposite side of the spray component, collect the liquid medicine on the target plant without deposition, and then withdraw it into the liquid tank for recycling, which can greatly improve the effective use of pesticides. rate.
Low volume spray
Refers to the constant application of the unit area, the pesticide stock solution is slightly diluted, the water consumption is equivalent to 1/5 to 1/10 of the conventional spray technology. This technology improves work efficiency and is widely used in greenhouses and mountains.
Electrostatic spray
The high-pressure electrostatic generating device enables the droplets to be electrically sprayed, and the deposition amount of the liquid droplets on the surface of the blade is remarkably increased, and the effective utilization rate of the pesticide can be increased to 90%.
Roller smear
It is mainly used for the internal absorption of herbicides. The liquid is exuded from the surface of the medicine roller by a medicine roller (a type of plaster overflow made of a foam material capable of absorbing the liquid medicine), and only needs to contact the blades of the upper part of the weeds. It works. This method can almost completely apply the agent to the surface of the target plant without causing the liquid to spill and drip.

The roller coating plate refers to a method of color on the surface of the aluminum and coated with PVDF coating and the coating plate processed into a certain structure through processing. Roll coating aluminum plate is of high-tech with rolling the processing technology of high performance,attached to the surface of the aluminum plate by PVDF, the adhesion is strong, and the color is very realistic so that the product life length is extended. The surface is smoothness, bright and uniform. The film thickness and coating surface of aluminum is thinner than film coated plate.Because of roller coated aluminum plate reflection is excellent,clean and not easy changed of color,the price is much higher.
