| Abstract:
More effective utilization of the greenhouse floor area for crop production can be achieved with a movable row cropping system which increases row spacing as the plants develop. The movable row consists of a continuous, plastic film tube 15 cm in diameter and a 0.32 cm steel cable threaded within the tube. Seedlings were transplanted into the tube which carried nutrient solution and provided an environment for the growth of their root systems. The cable was attached to a frame located at each end of the greenhouse through a roller mechanism. The roller mechanism could travel along the frame which traversed the width of the greenhouse. This provided a catenary structure, attached only at its ends, which supported the plant-growing tube above the floor and created a cropping system capable of variable row-to-row spacings. | |
