Plant protection system

摘要

A plant protection system which utilizes a housing and a heat source is disclosed. In one embodiment, the invention includes a truncated cone shaped housing which is positioned on the ground so as to surround the tree or other plant. The heat source may, for example, include a water pipe and spray emitter located within the housing to provide water in spray form near ground level adjacent the tree. A deep well may be used as the water source, thus providing water at a temperature higher than the ambient temperature. As the warm water spray rises within the housing, heat is transferred to the interior of the housing. An extension having side walls in the form of an inverted cone may be secured to the upper end of the housing to provide a further heating effect. Any of various designs and constructions for the housing and the extension may be employed. The heating means may also be provided from any of various sources and materials.
