Solar energy geothermal heating system for agricultural greenhouse planting

Abstract

The invention discloses a solar energy geothermal heating system for agricultural greenhouse planting. The solar energy geothermal heating system for the agricultural greenhouse planting comprises a pre-buried electric heated tube, a greenhouse body and a solar energy photovoltaic plate. A nutrition soil layer is paved on the bottom of the greenhouse body. The pre-buried electric heated tube is paved on the bottom of the nutrition soil layer. A plurality of temperature sensors is pre-buried in the nutrition soil layer above the pre-buried electric heated tube. The temperature sensors are connected with a controller. The pre-buried electric heated tube is electrically connected with the controller. The controller is connected with an accumulator. The accumulator is connected with the solar energy photovoltaic plate. The controller is connected to an electric supply power grid. The nutrition soil layer in the greenhouse body is heated by the pre-buried electric heated tube, the continuous heat supply to the soil is guaranteed, the temperature stabilization is ensured, and the solar energy geothermal heating system is good for planting crops in the greenhouse body. Even in cold winter, the situation of freezing the root of the crops cannot be generated. Compared with the traditional mode of heating the air to improve the temperature in the greenhouse body, the mode of the solar energy geothermal heating system for heating the nutrition soil layer is capable of guaranteeing the survival and growth of the crops better.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a solar geothermal heating system for agricultural greenhouse planting. Background technique [0002] Due to the large temperature difference between the north and the south of our country and the cold winter, in order to improve the survival rate of crops and ensure their normal production, people generally use greenhouses for planting. At present, when planting in greenhouses, the method of heating air is usually used to realize greenhouse planting, but this heating method can not only ensure that the crops above the soil layer are not affected by low temperature frostbite, but it does not have a good heating effect on the roots of crops in the soil layer . Therefore, it often occurs that the roots of crops are damaged by freezing. Therefore, existing agricultural greenhouses need to be improved. Contents of the invention [0003] The object of the present in...
