Greenhouse crop carbon dioxide generation and collection and fertilizer application system and implementing method thereof

Abstract

The invention discloses a greenhouse crop carbon dioxide generation and collection and fertilizer application system and an implementing method thereof. The system comprises a fermentation device, a compression and storage device, a mixing and preparing device and a control device. The compression and storage device is arranged between the fermentation device and the mixing and preparing device and used for compressing and storing carbon dioxide generated in the fermentation device, conveying the carbon dioxide into the mixing and preparing device for mixing and preparing when the carbon dioxide is needed for fertilizer applying so that the concentration of the carbon dioxide needed for fertilizer applying can be reached. By means of the system, pure carbon dioxide gas can be prepared andcollected; by mixing the obtained pure carbon dioxide gas with air in a gas mixing chamber according to a required ratio, the carbon dioxide gas with a proper concentration required for various stagesis provided for a greenhouse, and the concentration of carbon dioxide entering the greenhouse is suitable for meeting fertilizer applying needs. The system has the advantages of being stable in performance, high in safety, low in cost, convenient to detach and assemble, low in energy consumption and the like.

Description

Technical field [0001] The invention belongs to the field of agricultural facilities, and more specifically, relates to a carbon dioxide generation collection and fertilization system for greenhouse crops and an implementation method thereof. Background technique [0002] Greenhouses or glass greenhouses can increase the internal temperature in winter, which is conducive to accelerating the growth of crops. However, because the crops are isolated from the outside atmosphere, there will be two unfavorable factors: one is to reduce the solar transmittance, and the other is to affect the greenhouse and the outside world. Gas circulation has seriously affected the growth and development of crops. Due to insufficient ventilation in the greenhouse, it is very easy to cause the phenomenon of lack of carbonization, and then the photosynthesis of crops will slow down, affecting the growth of plants, and even causing plants to wither and die. In the actual process, the content of carbon d...
