Investigation about wetting ability (surface tension) of water used for preparation of pesticide solutions | Preučevanje omočitvene sposobnosti (površinske napetosti) vode za pripravo raztopin pesticidov

GANCHEV, Donyo Hristov
英语. The investigation about surface tension of water used for preparation of pesticide solutions reveals it is quite diverse and changeable without any logical correlation towards location, time, and type of water source. Moreover, spraying with solutions with lower surface tension give bigger flow rates due to the lower resistance of fluid to the nozzles. The conducted trials show that plant surfaces with more rough texture require to be sprayed with pesticide solutions with lower surface tension. The wax content of the surfaces has no significant impact on surface tension requirement.

Raziskave glede površinske napetosti vode uporabljene za pripravo raztopin pesticidov so odkrile, da je ta zelo raznolika in, da se spreminja brez logične povezave glede na lokacijo, čas in vir vode. Škropljenje z raztopino z manjšo površinsko napetostjo daje večje pretoke zaradi manjšega upora tekočine v šobah. Izvedeni poskusi kažejo, da površine rastlin z bolj grobo teksturo zahtevajo škropljenje z raztopino pesticidov z manjšo površinsko napetostjo. Vsebnost voska na površini nima značilnega vpliva glede zahtev o površinski napetosti raztopine pesticidov.
