Solar supplying geotherm greenhouse gravity drip irrigation system

Abstract

The invention relates to a solar supplying geotherm greenhouse gravity drip irrigation system. The solar supplying geotherm greenhouse gravity drip irrigation system comprises a greenhouse which is provided with a greenhouse wall. The solar supplying geotherm greenhouse gravity drip irrigation system is characterized by further comprising a solar thermal collector and a buried pipeline, wherein the buried pipeline is connected with a drip irrigation tape. The solar thermal collector is fixed on the top of the greenhouse. A water delivering pipe is installed on the top of the solar thermal collector and a water outlet pipe is installed at the bottom of the solar thermal collector. A water tank and a water inlet pipe are respectively connected with the water delivering pipe. The tail end of the water outlet pipe is connected with the water tank. A frame and a main pipe are respectively installed on the bottom of the water tank. The main pipe is connected with the buried pipe. The drip irrigation tape is directly connected with the buried pipe through a locking nut. The solar supplying geotherm greenhouse gravity drip irrigation system utilizes a solar energy system to heat water in the water tank and the hot water is leaded into underground through the buried pipe. Soil is heated through the heat exchanged of the soil and the buried pipe. Thus, soil temperature is increased and the requirements of crop root systems are met. Energy is saved and the purpose that crop is high in yield is achieved.

Description

technical field [0001] The invention relates to a greenhouse soil heating system, in particular to a greenhouse gravity drip irrigation system for solar energy supplying geothermal heat. Background technique [0002] Greenhouse is a building specially used for crop cultivation and growth, which can protect plants from climate, temperature or mosquitoes, so that crops can grow quickly. At the same time, the popularization and application of solar greenhouses is an important symbol of modern agriculture. It gets rid of the constraints of natural climate conditions in traditional agriculture, greatly increases the output, and ensures a balanced supply of vegetables throughout the year. Most of the solar greenhouses in China are distributed in areas north of 35° north latitude. In late autumn, winter and early spring, the climate is cold and the ground temperature is very low, which makes it difficult to meet the requirements of crop growth. The reason is that plant growth is n...
