Temperature controlled automatic water dispenser to provide subsurface irrigation for orchard, farm amp; vineyard plants

摘要

A temperature controlled automatic water dispenser for irrigating plant roots and the like in which an increase in ambient temperature will cause the device to dispense water automatically for irrigation use. The dispensed water is conveyed through appropriate water conveying lines to a plurality of seepage nozzles which are inserted into the soil adjacent to the plant roots. Thus, the irrigation water flows from the dispenser device directly to the roots of selected plants during intervals of rising temperature. When the ambient temperature stabilizes, or whenever the temperature is falling, the device will not dispense water.
