Abstract

The invention relates to the technical field of adding carbon dioxide to greenhouse crops in protected agriculture, in particular to a fermentation type carbon dioxide generation device for greenhouse crops. The device comprises a fermentation tank and a gas outlet duct. Crop stems to be fermented are filled in the fermentation tank, and a water spraying system used for spraying and resupplying water to the crop stems to be fermented in the fermentation tank is arranged on the fermentation tank. The gas outlet duct is connected with the fermentation tank and used for delivering carbon dioxide generated in the fermentation tank. The crop stems are used as raw materials, and are subjected to harmless composting treatment at natural high temperature in a greenhouse so as to generate carbon dioxide, and accordingly, agricultural wastes are recovered. Further, the device is convenient to operate, is low-cost by utilizing the raw materials wide in source, and is suitable for farmers. In addition, composting speed of the stems is increased on favorable conditions of temperature and light in the greenhouse, the link of crushing the stems is avoided, and the composted stems can be returned to fields directly, so that high-efficiency utilization of resources and energy saving and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of adding carbon dioxide to greenhouse crops in facility agriculture, in particular to a fermentation carbon dioxide generating device. Background technique [0002] Photosynthesis is the basic feature of the life activities of green plants and the material and energy basis for the growth and development of cultivated crops. The crop absorbs water and inorganic salts through the root system, and uses carbon dioxide (CO2) in the air 2 ) undergoes photosynthesis to produce organic matter under the irradiation of sunlight. 85% of the dry matter of crop straw is sugar and other carbohydrates, and most of the carbon comes from CO in the air 2 , so it is the main carbon source for plant photosynthesis, CO in the air 2 The concentration directly affects the photosynthesis efficiency of crops. [0003] CO in the facility 2 The diurnal variation range of the concentration was significantly higher than that in th...
