| Tóm tắt: | A computerized measuring system to analyse the
vector field of the air velocities in a volume surrounding the fan of air assisted sprayers usually used in tendone vineyards was designed and built.
The performance of three different sprayers was
tested: the first, a traditional air-convection sprayer,
the other two, suitably designed for treatments in tendone vineyards.
The air flow which exited through the discharge
diffusers and moving towards the target sucked air
from the surrounding environment that enlarged the
flow rate on the target.
The available flow was that which reached the vegetative and productive area, placed in a horizontal position respectively at 1.8 m and 2.0 m from the ground
plane. The pneumatic sprayer produced an air flow
clearly directed towards the top of the vines. |
