Abstract

The invention discloses a carbon dioxide gas fertilizer additional application controller which comprises a comparison circuit, a timing circuit, a clock circuit and an executing mechanism driving circuit. The comparison circuit and the clock circuit are electrically connected with an input side of the timing circuit, and an output side of the timing circuit is electrically connected with the executing mechanism driving circuit. The carbon dioxide gas fertilizer additional application controller has the advantages that the carbon dioxide release time can be controlled for different degrees of illumination intensity, the concentration of carbon dioxide in greenhouses can be kept, and accordingly requirements of photosynthesis of crops can be met; photosynthesis of plants is mainly carried out in periods between a half hour after sunrise and 2 o'clock in the afternoons, control is carried out by the cock circuit, carbon dioxide is released once at intervals of 60 minutes, direct-current motors can clockwise and anticlockwise rotate under the control of the executing mechanism driving circuit, and accordingly valves can be turned on and off; the carbon dioxide can be automatically quantitatively released to the greenhouses in a timing manner, 220V alternating currents or labor management can be omitted, and the carbon dioxide gas fertilizer additional application controller is convenient to mount, low in investment and quite suitable to be used by rural small-scale growers.

Description

technical field [0001] The invention relates to the technical field of agricultural facilities, in particular to a carbon dioxide gas fertilizer increasing controller. Background technique [0002] Plastic greenhouses in solar greenhouses are widely used in agricultural production. When vegetables are produced in greenhouses, the greenhouses are often kept in a closed state for heat preservation. This causes the air in the greenhouses to be relatively isolated from the outside air, and carbon dioxide cannot be replenished in time. At night, crops respire to produce a certain amount of carbon dioxide, and soil microbial activities and organic matter decomposition and fermentation release a large amount of carbon dioxide, which gradually increases the concentration of carbon dioxide in the greenhouse, and generally reaches the peak before sunrise. After sunrise, crops start photosynthesis, consume carbon dioxide, and the concentration of carbon dioxide in the shed drops sharpl...
