Abstract

The invention relates to a greenhouse soil temperature adjusting pipeline and device. The greenhouse soil temperature adjusting pipeline comprises support rings, support ribs and dense mesh cloth; thesupport rings are distributed at equal intervals, the support ribs are bundled outside the support rings at equal intervals, and the dense mesh cloth wraps the support ribs. The greenhouse soil temperature adjusting device comprises the temperature adjusting pipeline, an outlet of the temperature adjusting pipeline extends out of a soil layer, an inlet of the temperature adjusting pipeline is connected with an air inlet pipe, two air inlets are formed in the air inlet pipe, one air inlet is formed between two layers of heat preservation film of a greenhouse, the other air inlet is formed in the greenhouse, a switching valve is arranged between the two air inlets, and an electric heating section is arranged on the air inlet pipe. According to the greenhouse soil temperature adjusting pipeline and device, high-temperature air naturally formed in the indoor top space and an electric heating device are utilized to provide a heat source, and then hot air is introduced into a heating pipeline in soil through a pipeline fan. By comprehensively utilizing the functions of equipment of adjusting the air inlets, the wind speed and the heating power, the purpose of maintaining soil temperature is achieved.

Description

technical field [0001] The invention relates to a soil temperature regulating device, in particular to a greenhouse soil temperature regulating device. Background technique [0002] In the northern regions of my country, especially in the cold regions of Northeast China, the soil temperature in winter greenhouses is lower than the root growth temperature requirements of melons, fruits and vegetables. It is difficult to grow fruits and vegetables, and the cost of soil warming is high. In order to solve this problem, the applicant has previously proposed some patent applications on greenhouses (for example: application number CN201510984365.7, title "a greenhouse without heating facilities"; application number CN201610158642.3, title "a natural Heating greenhouses", etc.), using double-layer skeleton double-layer plastic film, built-in insulation quilts and other means to improve the insulation effect of the greenhouse. However, the improvement of the greenhouse alone cannot ...
