Embodiment 1

[0029] The present embodiment provides a schematic view of a set of vegetable greenhouse irrigation carburizing temperature in one of; the following steps:

[0030] Activate the cooling unit 8 circulating water bath, provided the cooling water temperature 3 ℃; cooling water temperature reaches the set temperature, the cooling chamber is opened hydrate water inlet control valve 78, the cooling water filled into the cavity 74, the entire cooling chamber the temperature was maintained at 3 ℃; hydrate formation chamber opens into the water control valve, the water reservoir by the pump chamber into the hydrate formation, the water is completed, close the water control valve, the control valve is open gas injection, injecting carbon dioxide into hydrate formation chamber so that the pressure chamber is maintained at a hydrate 4.0MPa, constant voltage hydrate;

[0031] After completion of gas injection, starting 75 stirring, stirring may provide more physical disturbance of hydrate form...

Abstract

The invention relates to the technical field of agricultural production, in particular to a vegetable greenhouse and method integrating carbon-increasing and temperature-controlled irrigation; mainly including a hydrate generation system, a vegetable greenhouse and a control system; utilizing the endothermic effect of carbon dioxide hydrate decomposition process and hydration carbon dioxide and water produced by decomposition. The invention provides a vegetable greenhouse technology capable of simultaneously controlling temperature, increasing carbon and irrigating at one time. The new greenhouse technology provided by the present invention can integrate the three requirements of increasing carbon dioxide, temperature control, and irrigation in traditional vegetable greenhouses, greatly simplifying the greenhouse operation process, reducing production costs, and can also be used to control the concentration of carbon dioxide while increasing the concentration of carbon dioxide. Greenhouse temperature is conducive to the accumulation of nutrients in vegetables and improves the quality of vegetables.

Description

Technical field [0001] The present invention belongs to the field of agricultural production, and particularly relates to a method for vegetable greenhouse temperature set by a carbon in one of the irrigation. Background technique [0002] With the improvement of living standards, demand for fresh vegetables also grew sharply, especially in-season vegetables; therefore, the demand for vegetable greenhouses is gradually increasing. Vegetable greenhouse cultivation apparatus is an analog of vegetable growth, due to the greenhouse vegetables to ensure a certain temperature in the greenhouse plant growth requirements, it is required to maintain a sealed state in a greenhouse plant growth, which leads to the air in the greenhouse with the outside can not be for circulation, while plant growth requires a lot of carbon dioxide gas will continue to consume carbon dioxide in the greenhouse; Once the concentration of carbon dioxide to reduce greenhouse, plant photosynthesis will be limited...
