Plant Protection Drone Spraying Guide

In September, the cotton harvest is just around the corner. The last chemical agent before the harvest is to apply the defoliant to the cotton. The cotton defoliant mainly plays the role of defoliating and accelerating the ripening. , The lower part is evenly covered with medicine.

As an auxiliary spraying machine, the plant protection drone is very suitable for removing chemicals from cotton. It is an intelligent spraying machine. The flight speed/spraying flow/distance from the crop surface can be controlled by software, which is better than manual spraying. The spraying uniformity of the controlled machine is better, and the drone has a breakpoint battery life function to prevent re-spraying and missed spraying of the potion.

• Spraying mu dosage

According to the concentration of the defoliant deployment, the spraying amount of the drone can be up to 10L/min. This spraying amount can also be designed. According to the requirements of different dosages, different concentrations can be prepared, and the amount of spraying per mu will also be different.

• Working height

The operating height refers to the height of the vegetation surface in the drone. In the selection of the height, the spray uniformity and droplet penetration should be considered comprehensively. Increasing the height is conducive to the improvement of spray uniformity but will reduce the droplet penetration. The height should be lowered appropriately under the premise of avoiding spray leakage.

• Operating speed

The flight speed directly affects the droplet penetration. For contact agents, a relatively low operating speed should be selected to obtain better droplet penetration and deposition in the middle and lower parts.

• Line spacing

The spraying distance of the drone at a height of 2 meters is 8.6 meters, but the spraying edge will be thinner than the spraying agent, and it will be affected by the wind, so the spraying distance of the drone is generally set at about 7-8 meters , in order to ensure the uniformity of spraying.
