摘要： A crop protection device that is designed to cover a number of citrus fruit trees during periods of cold weather. The device is a heated canopy system that is made from a lightweight, high strength fabric that is supported by a number of ground-mounted frame members. The ends of the fabric are attached to one another by a drawstring, which is wound through a series of eyelets on the fabric. The device also includes a heater and blower unit that continuously blows hot air within the confines of the fabric after the fabric has been mounted over at least one citrus plant.
