Heating device and method

Abstract

The embodiment of the invention provides a heating device and a method. The heating device is used for heating frozen earth around tree roots in a soil ball of a tree, wherein the soil ball of the tree is positioned in a tree hole. The device comprises an electrode which is paved around the soil ball of the tree in the tree hole; the part of the electrode bended and extended from the lower side of the soil ball of the tree penetrates into a spool, and a power supply can electrify the electrode through the upper end of the part, so that the electrode generates heat. According to the embodiment of the invention, the tree roots relatively quickly absorb water in a frozen earth layer while growth of the tree roots is not facilitated as soil is anoxic as a result of excessive melt water after the frozen earth layer is unfrozen.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of garden planting, in particular to a heating device and method. Background technique [0002] In garden planning and landscaping, in the northern part of China, in winter, when the temperature drops below 0°C, the moist soil freezes, and the trees are dormant at this time. Until spring, the temperature begins to rise slowly, and the newly moved large The upper part of the tree starts to move slowly and needs to absorb a lot of water, but at this time the underground soil layer is thawing slowly, and the roots of the tree cannot absorb water for a long time in the permafrost layer, and the evaporation of the tree is greater than the supply, which can easily cause the death of the tree. [0003] In the traditional way of pouring thawed water on the surface, if the thawed water is poured too much, the newly thawed soil will be deprived of oxygen due to excessive water, which is not c...
