Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 4,   Pages 455-461 doi: 10.15302/J-FASE-2018232

Abstract:

Prewetting process can reduce the contact angle between the droplet and the leaf blade, so that thedroplet can more easily wet and spread, thereby increasing the quantity of deposition.The results revealed that with no prewetting, droplet deposition quantity decreased with increasing leafAfter prewetting, the mean droplet deposition quantity on plots B, C and D increased by 39.8%, 9.7% andIt was also found that the mean droplet deposition quantity in each leaf blade angle range increased
