If the rice applicator experiences drift during spraying, don't worry, because drift is still necessary in order for the mist or Fengli to accurately reach the rice. Therefore, it is necessary to understand the impact of drift:

What factors will affect the drift effect of rice applicators?

1. The effect of wind speed on drift.

The farther the nozzle is from the target, the more severe the phenomenon of drift.

3. Increasing the walking speed can lead to upward airflow, which forms a vortex behind the spray and rolls up small droplets to form drift.

When the temperature is above 25 ° C and the relative humidity is low, the evaporation factor will exacerbate the drift of small droplets.

5. The spray pressure is proportional to the drift.

After understanding the above factors causing drift, corresponding measures can be taken to effectively control this phenomenon, such as reducing the spray pressure to obtain larger droplets, selecting anti drift nozzles, reducing the height of the spray bar, slowing down the walking speed, and increasing the air flow auxiliary conveying mechanism.

However, people can also take advantage of the phenomenon of drift. Generally, spray is divided into two categories: targeted spray and drift spray. The use of drift spray can often reach the distance and area that targeted spray cannot reach. However, such spray must be carried out within a controllable range, otherwise it may cause harm or pollution and cause legal problems.

Within a controllable range, such as grasslands and vast farmland, natural wind or powerful fans can be used for blowing, which can greatly improve work efficiency and quickly control diseases, pests, and weeds.

The fan blowing technology can be used to drift spray the crown of orchards, forest belts and other trees. The air current carries small droplets into the crown, and the branches and leaves turn under the action of the air current, thus increasing the attachment rate of droplets. In addition, for tall trees and huge crowns, drifting spray can be regarded as a way to get twice the result with half the effort.

The phenomenon of droplet drift, like anything else, has two sides. It can be utilized and controlled according to our needs to achieve our goal of protecting crops.
