Zusammenfassung: | The present invention relates to an irrigation and fertigation system. A turbidity sensor is installed between a discharge pipe and a first branched pipe, and turbidity of ground water flowing in from a well by means of a feed pump is measured at the discharge pipe, and when the value of the measured turbidity exceeds a reference turbidity value for ground water, a conversion valve (30) is activated downward to drain the ground water, and when not exceeded, a conversion valve (26) is activated upward to allow the ground water to flow through to a distribution pipe, thereby preventing small spray holes of a drip pipe from becoming blocked. A transparent pipe is provided to one side of the discharge pipe (22) to allow turbidity of the ground water to be visually determined, and when the water discharged from the feed pump is confirmed via the transparent pipe to be mixed sandy water in which sand is mixed in, the conversion valve (30) is activated downward to drain the ground water, and when no grains of sand are seen via the transparent pipe in the ground water discharged from the feed pump, the conversion valve (26) is activated upward to allow the ground water to flow through to the distribution pipe, thereby preventing small spray holes of the drip pipe from becoming blocked. A liquid fertilizer feed pump is installed to one side of a liquid fertilizer inflow pipe to facilitate smooth supply of liquid fertilizer thereinto, regardless of whether a liquid fertilizer supply tank is at the same level as or lower than the irrigation and fertigation system.
La présente invention concerne un système d'irrigation et de fertigation. Un capteur de turbidité est installé entre un tuyau d'évacuation et un premier tuyau ramifié, et la turbidité de l'eau souterraine s'écoulant à partir d'un puits au moyen d'une pompe d'alimentation est mesurée au niveau du tuyau d'évacuation, et lorsque la valeur de la turbidité mesurée dépasse une valeur de turbidité de référence pour l'eau souterraine, une soupape de conversion (30) est activée vers le bas pour évacuer l'eau souterraine, et lorsqu'elle n'est pas dépassée, une soupape de conversion (26) est activée vers le haut pour permettre à l'eau souterraine de s'écouler dans un tuyau de distribution, empêchant ainsi l'obstruction de petits trous de pulvérisation d'un tuyau d'égouttement. Un tuyau transparent est disposé sur un côté du tuyau d'évacuation (22) pour permettre à la turbidité de l'eau souterraine d'être visuellement |
