Embodiment 1

[0029] This embodiment provides a schematic diagram of a vegetable greenhouse integrating carbon-increasing and temperature-controlled irrigation; the steps are as follows:

[0030] Start the cooling circulating water bath machine 8, and set the cooling water temperature at 3°C; after the cooling water temperature reaches the set temperature, open the cooling water inlet control valve 78 in the hydrate formation chamber, fill the cavity 74 with cooling water, and turn the entire cooling chamber The temperature is maintained at 3°C; open the water inlet control valve of the hydrate formation chamber, and the water in the reservoir enters the hydrate formation chamber through the water pump. After the water injection is completed, close the water inlet control valve, open the gas injection control valve, and inject carbon dioxide into the hydrate formation chamber. chamber, so that the pressure in the hydrate generation chamber is maintained at 4.0MPa, and the hydrate is generate...

Abstract

The invention relates to a vegetable greenhouse with integrated functions of carbon increasing, temperature controlling and irrigation and a method thereof. The vegetable greenhouse mainly comprises ahydrate generation system, a vegetable greenhouse and a control system; endothermic effect of a carbon dioxide hydrate decomposition process and carbon dioxide and water generated by hydrate decomposition are utilized. The invention provides a vegetable greenhouse technique capable of simultaneously controlling temperature, increasing carbon and irrigating at a time. According to the novel greenhouse technique provided by the invention, the three requirements of the traditional vegetable greenhouse on carbon dioxide increasing, temperature control and irrigation can be integrated; therefore,the greenhouse operation process is greatly simplified, the production cost is reduced, the carbon dioxide concentration is raised, the greenhouse temperature can be controlled, and the accumulation of nutrient substances in vegetables is facilitated so that the vegetable quality is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a vegetable greenhouse and a method integrating carbon-increasing and temperature-controlled irrigation. Background technique [0002] With the improvement of living standards, the demand for fresh vegetables has also increased sharply, especially off-season vegetables; therefore, the demand for vegetable greenhouses has gradually increased. The vegetable greenhouse is a planting equipment that simulates the growth of vegetables. Since the temperature in the vegetable greenhouse must meet certain plant growth requirements, it is required that the greenhouse be kept in a sealed state during the plant growth process, which causes the air in the greenhouse to be unable to communicate with the outside world. For circulation, and plant growth requires a large amount of carbon dioxide gas, which will continuously consume carbon dioxide in the greenhouse; onc...
