Soilless culture system capable of comprehensively utilizing carbon dioxide

Abstract

The invention discloses a carbon dioxide comprehensive utilization soilless culture system, which relates to the field of carbon dioxide comprehensive utilization soilless culture and comprises a bottom soilless vegetable culture pond, a first culture solution conveying pipe, a carbon dioxide main tank connecting pipe, a culture solution pipeline, a high soilless vegetable culture pond and a carbon dioxide storage and conveying system, the carbon dioxide storage and delivery system is formed by arranging a carbon dioxide main tank connecting pipe, a carbon dioxide delivery valve, a two-sample carbon gas pipeline, a carbon dioxide gas overflow hole, a carbon dioxide delivery connecting pipeline and a carbon dioxide main tank body structure on the periphery of the soilless culture pond; through the design of the bottom-layer soilless vegetable culture pond, the culture solution connecting and conveying pipeline and the high-layer soilless vegetable culture pond, the problems that according to existing soilless culture, due to the planting environment, the photosynthesis of vegetables is reduced, the photosynthesis of three-dimensional planting is reduced, the condition of the vegetables is unstable, and the occupied space is large are solved. And the input-output ratio is difficult to greatly increase.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation for comprehensive utilization of carbon dioxide, in particular to a soilless cultivation system for comprehensive utilization of carbon dioxide. Background technique [0002] Soilless culture refers to the cultivation method in which water, peat or forest humus, vermiculite and other media are used as the substrate for plant roots to fix plants, and the plant roots can directly contact the nutrient solution. It has the advantages of water saving, fertilizer saving, high yield, cleanliness, sanitation and pollution-free, avoiding continuous cropping obstacles, etc. It can be used for cultivating flowers, medicinal plants, etc. The existing soilless cultivation workplaces are usually set up in greenhouses or indoors. However, the existing soilless cultivation usually needs to occupy a large site for laying soilless planting equipment, which occupies a large area of ​​the site, and does ...
