Method for additionally applying carbon dioxide air fertilizer to warm-house booth through agricultural organic waste fermentation

Abstract

The invention discloses a method for additionally applying a carbon dioxide air fertilizer to a warm-house booth through agricultural organic waste fermentation. The method comprises the following steps of: uniformly adding microorganism fermentation species in an amount of 0.3 percent of the weight of a fermentation substrate into the fermentation substrate, wherein the mixture of crop straw and animal manure is taken as the substrate, and the ratio of C to N in the substrate is 40 / 1; putting the mixture into a simple fermentation barrel; directly fermenting in the warmhouse booth to release the carbon dioxide air fertilizer; after fermenting for about 3 weeks, taking a part of fermentation waste residues out of the bottom of the simple fermentation barrel; adding a part of new substrate and species from top of the sample fermentation barrel; and keeping the concentration of the carbon dioxide air fertilizer in the warm-house booth at least at 800 mumL / L. Organic waste causing severe pollution on the ecological environment is subjected to reasonable carbon cycle, so that the pollution of the organic waste on the ecological environment can be avoided, and the practical production problems of severe lack of CO2 in warm-house booth cultivation, soil deterioration and the like are solved, the pollution is avoided, C and N resources are utilized fully, and the economic benefit and social effect are remarkable.

Description

technical field [0001] The invention belongs to the technical field of facility vegetable production, and in particular relates to a method for adding carbon dioxide gas fertilizer to greenhouses by fermenting agricultural organic waste. Background technique [0002] Adding carbon dioxide gas to the crops planted in the greenhouse can promote the photosynthesis of the crops, increase the yield of the crops, and improve the quality of the products. The carbon dioxide gas applied as fertilizer to the greenhouse can be released directly with dry ice or compressed carbon dioxide in steel cylinders, or it can be obtained from the flue gas of burning carbonaceous substances, but the most convenient, cheapest and most commonly used method is to use directly Strong acid and solution containing ammonium bicarbonate reaction to the system. The cost of releasing carbon dioxide with compressed carbon dioxide packed in dry ice or steel cylinders is relatively high, and the carbon monoxi...

Problems solved by technology

However, it is found in the application that this method takes 4-5 days to reach the fermentation temperature of 50°C when the temperature in the greenhouse is low, and the design of the fermentation device is relatively complicated, the cost is high, and sulfuric acid is still used in the gas absorption component , farmers are not easy to buy and there is danger, which affects the popularization and application of this invention
