The Technical Research For Both CO₂ Enriching And Temperature Rising In Greenhouse By Liquefied Petroleum Gas

Owing to the carbon dioxide concentration (CO2) lower in the daytime it doesn't meet the demand of plants growing which causes the drop of photosynthesis action in aspect of the plants and results in the plants' output reducing. In order to solve the problems above, we developed to design the technique and standby equipment of LPG greenhouse CO2 enriching and temperature rising. The standby equipment provides the proper CO2 concentration to increase the luxuriate photosynthesis action for plants, reaching to the effect of increasing output and quality.This paper is to illustrate the safety and necessity of the technique application, to sum up the best CO2 concentration and best time and to analyze the temperature distribution of standby facilities based on the results of study, experiments, analysis and mathematics calculation. Comparing with other techniques economically, an advancement and a pragmatism of the technique mentioned above have been determined. We also prove the utility effect of the technique through the contrast test.
