Fluid nutrient delivery system and associated methods |
摘要 |
A method for efficiently delivering an aqueous solution to plants includes positioning a distal portion of a microporous hydrophobic tubing coated with a hydrophilic polymer adjacent a root system of a plant and channeling an aqueous solution from an inlet to the distal portion through a lumen. The tubing along the distal 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. The aqueous solution is held in a reservoir, from which it can be channeled to the hydrophilic device's inlet. A nutrient solution can also be channeled to the plant roots via additional tubing.
