<P>PROBLEM TO BE SOLVED: To provide a heating element burying machine reducing fuel expenses by performing direct heating of a good heat transfer efficiency through burying of heating elements, reducing labor of burying itself of heating elements, and burying heating elements according to cultivation places of cultivated plants. Ž<P>SOLUTION: This heating element burying machine includes a ditch forming instrument 1 which is attached to a ditch forming place projecting downward from soil tilled in the rear of a self-travelling tiller having a tilling blade, and advances together with the tiller to form ditches in the soil just after tilling, and a heating element supplying device 2 which continuously or intermittently supplies heating elements for warming a land from the upper side to a heating element supplying place in the rear of the ditch forming instrument 1. The heating element supplying device 2 includes a heating element holder 21 which collectively holds lengthy heating elements on the upper part, and a compaction roller 22 which rolls on soil in a place lower than the ditch forming place. The compaction roller 22 dispatches one by one, while compaction rolling, heating elements H drawn from the heating element holder 21 to the ditch forming place. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
