Embodiment Construction

[0024] Figure 1 ~ Figure 3 Combined with a fermentation device for carbon dioxide fertilization in greenhouses, it includes a base assembly 1, the base assembly 1 is composed of an umbrella grid 11 and 4 supports 12, and the 4 supports 12 are evenly and symmetrically arranged on the umbrella grid 11 the lower end. The umbrella-shaped grid 11 is composed of several grid bars 111 and is shaped like an umbrella surface, so the circular bottom of the umbrella-shaped grid 11 is hollow. The grid bar 111 can be made of materials such as steel bars, wooden bars and bamboo poles. The gap between two adjacent grid bars 111 is 8-10 cm, and the gap refers to the largest gap between the two grid bars 111 . In actual use, the diameter of the bottom of the umbrella grid 11 is adjusted accordingly according to the area of ​​the greenhouse and the number of fermentation devices placed in the greenhouse.

Abstract

The present invention discloses one kind of fermentor for applying CO2 fertilizer in greenhouse. The fermentor includes one pedestal assembly, one barrel on the pedestal assembly, one thermometer set inside the barrel, and one gas absorbing assembly for sealing the cavity of the barrel on the barrel. The fermentor of the present invention is matched with the method in the patent of ZL 200410024965.0, and has high CO2 gas yield and capacity of avoiding the poisoning of NH3 and one harmful gases generated during fermentation on crop.

Description

technical field [0001] The invention relates to a fermentation device, in particular to a fermentation device for carbon dioxide fertilization in greenhouses by fermenting agricultural organic waste. Background technique [0002] The inventor once applied for the invention patent of "method of fertilizing carbon dioxide in greenhouses by fermenting agricultural organic waste" on June 4, 2004, and it was authorized on March 15, 2006, with the patent number: ZL200410024965.0. This method has achieved satisfactory results after 3 years of field demonstration experiments. This method can maintain greenhouse CO2 around the clock 2 Concentration above 500μl / L, after 3 weeks of treatment, the yield of most leafy vegetables can be increased by more than 80%, and the quality of vegetables can be significantly improved; it can be put on the market 1 week earlier than the control greenhouse, and the fermentation residue can be used to solve the soil degradation of the greenhouse ques...
