The utility model provides a combined type temperature regulation pipeline structure for a vegetable greenhouse. The combined type temperature regulation pipeline structure is characterized in that a longitudinal water inlet pipe and a longitudinal water return pipe are installed on the two sides of a vegetable bed of the greenhouse respectively; a plurality of transverse bottom heat pipes are installed inside soil of the vegetable bed; the two ends of each bottom heat pipe are provided with an upward vertical heat pipe, wherein the upper end of one vertical heat pipe is communicated with the water inlet pipe, and the upper end of the other vertical heat pipe is communicated with the water return pipe; the water inlet pipe and the water return pipe are communicated with a main water inlet pipe and a main water return pipe respectively. The combined type temperature regulation pipeline structure solves the problem that deep ploughing is affected or heat energy is wasted if heating pipelines are laid underground for the vegetable greenhouse, and is quite suitable for being used in the vegetable planting greenhouse.
