Factors Affecting Droplet Loss behind Canopies with Air-Assisted Sprayers Used for Fruit Trees
نویسندگان
چکیده
Air-assisted sprayers are widely employed in orchards, but inappropriate spray parameters can lead to large droplet losses, pesticide waste, and environmental pollution. To investigate the factors affecting loss of an air-assisted sprayer behind canopies, a two-factor, five-level full experiment was conducted actual orchard, where two were power gradient foliage area volume density (FAVD). In addition, location sampling point also considered data analysis, including horizontal distance, forward height. The results show that all significantly affected coverage (p-value < 0.01). showed increase then decrease with increasing gradient, maximum measured at P3 (forward speed: 0.49 m/s, pressure: 0.30 MPa, flow rate: 7.13 L/min) or P4 0.58 0.35 8.44 L/min). effect FAVD on had obvious regularity, this regularity did not change gradient. At different positions great differences. gradually decreases distance height, while distance. This study provides reference for reduce loss, support subsequent research precision spraying based FAVD.

but also improves the uniformity of the spray pattern. Turbulence chamber nozzles are available in a turbo flood tip and now in the turbo flat-fan design. The turbo flatfan design shows great improvements in pattern uniformity when compared to the extended range flat-fan and other drift reduction flat-fan designs. In addition, the turbo flat-fan has significantly reduced the percentage of drift...
متن کاملPreharvest factors affecting physiological disorders of fruit
Development of disorders during postharvest ripening and storage of fruit depends on a range of preharvest factors. The most obvious of these is maturity of fruit at harvest. However, a number of other factors may be just as important in ripening-related disorders and in determining how fruit respond to low temperatures or other imposed postharvest conditions. Fruiting position on the tree and ...
