The researches of sprayers work‘s quality for soil herbicides

For spraying of soil herbicides are particularly suitable hydraulic deflector, universal and globular slotted flat, and a pneumatic injector (air) slotted flat sprays. You can use and slotted twin, and spray with a hollow cone spray. The latest product to spray soil herbicides are special pre-emergence flat spray nozzles Lechler PRE-130-05 with a horizontal spray. The aim of the study was to determine the influence of type of spray pressure and the spray height for uniformity transverse distribution of soil herbicides. It is established that the width of the strip, spray all investigated nozzles depends on the operating pressure and the height of the spray, but in different degrees. Throughput of all investigated nozzles of the operating pressure varies in direct proportion. Theoretical calculation of the coefficient of variation of the transverse distribution of the spray pairs of all investigated sprayers, shows a very uniform distributionVytauto Didžiojo universitetasŽemės ūkio akademij
