| 摘要 |
This invention relates to a device for treatment of culture by moistening. This device comprises at least one practically horizontal tubular tank (3) having a slit (4) in which are clamped the upper ends (2) of flexible capillary wicks (1) adapted for resting on the vegetation. This tank (3) is intermittently fed with a pressurized liquid, such as a weed-killer. According to the invention, each inlet (5) through which pressurized liquid is intermittently fed to a tank (3) is provided with a calibrated orifice (6) acting as an atomizer for spraying liquid into the tank. Preferably, a ball valve (7) biased by a spring (9) against its seat (8) is provided for preventing the liquid from dripping into the tank (3) during interruptions of pressure. In case the upper ends (2) of the wicks (1) are so tightly clamped in the slit (4) of the tank that capillary flow would be impeded, a row of orifices (10) is provided along an edge of the slit (4 ) for allowing liquid to seep onto the wicks (1). |
