Fluid and nutrient delivery system and associated methods |
摘要 |
<p>A system and method for efficiently delivering an aqueous solution to plants includes a microporous hydrophobic tubing coated with a hydrophilic polymer that has a delivery portion positionable adjacent a root system of a plant and a lumen for channeling an aqueous solution from an inlet to the delivery portion. The tubing along the delivery portion has a porosity adapted for permitting a flow of the aqueous solution therethrough when acted upon by a surfactant root exudate generated by the roots due to water stress. A pressure regulating device is upstream of the tubing's inlet, and a reservoir adapted for holding the aqueous solution therein is situated in fluid communication with an upstream end of the pressure regulating device. Additional tubing can be provided for channeling a nutrient solution to the plant roots.</p> |
