[0002] In view of the reality that the facility cultivation in China is still in small farmers scattered operation, small scale, poor technical conditions, researchers have also developed and used more than a dozen methods to increase the CO2 concentration of vegetable greenhouse, but either unstable gas supply, or the process is complicated, or the cost is too high to accept. The most simple is the method of producing CO2 by the reaction of ammonium bicarbonate (NH4HCO3) and dilute sulfuric acid (dilute H2SO4). Even this method has very obvious defects:

[0003] First, special reaction device and concentrated sulfuric acid need to be purchased, and the cost required for each mu of seasonal vegetables is at least 600 yuan or more, and dilute sulfuric acid solution needs to be prepared every day to react with ammonium bicarbonate, which is complicated and labor-intensive.

[0004] Second, if the CO2 gas fertilizer required for one mu of greenhouse for seasonal vegetables is about several dozen kilograms of concentrated sulfuric acid, and even if the professional technicians use concentrated sulfuric acid very carefully, it is obviously too dangerous for farmers with low cultural level to store and use concentrated sulfuric acid, and the feasibility is smaller if used in large areas. INVENTION CONTENTS

[0022] Compared with the prior art, the utility model has the advantages that:

[0023] This new device for generating CO2 fertilizer through aerobic fermentation of agricultural waste has excellent ventilation due to its suspended bottom and air connection. This effectively improves the ventilation level of the device, promotes the complete decomposition of organic waste, and enables aerobic fermentation and decomposition of agricultural waste. Aerobic decomposition allows agricultural waste to be completely decomposed, releasing more CO2 gas to provide CO2 fertilizer for greenhouse vegetables.

[0024] Furthermore, the fermentation and decomposition of agricultural waste raises the internal temperature of the device. As the hot air rises, it also draws air into the device from the bottom, ensuring an aerobic fermentation state inside the device. This allows the organic waste to be completely decomposed, releasing more CO2 gas while reducing the generation of harmful reducing gases.

[0025] Specifically, the device uses aerobic fermentation of agricultural waste to produce CO2. It is not only simple to operate and has a simple structure, but also saves production costs, avoids the dangers of using concentrated sulfuric acid, increases safety, and is more practical and suitable for large-scale agricultural use.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0034] First, it's important to clarify that nature is constantly cycling carbon. CO2 in the air is converted into organic matter through plant photosynthesis, and this organic matter is then fermented and decomposed by microorganisms, releasing CO2 back into the atmosphere. Every year, vast amounts of agricultural waste (plant stalks, livestock manure, etc.) urgently need to be treated in rural areas of my country. The aerobic fermentation of this agricultural waste releases a significant amount of CO2 gas. If this CO2 can be utilized in greenhouse vegetable production, the CO2 fertilizer problem can be completely solved. Furthermore, the fermentation process releases trace amounts of gases such as NH3, which dissolve in the dew on vegetable leaves in the greenhouse, forming a foliar fertilizer ideally absorbed by plants. After fermentation, insect eggs and pathogens in the agricultural waste are killed, and the fermented raw materials become a hygienic and safe high-quality organic fertilizer for greenhouse vegetables. Applying this fertilizer in greenhouses can effectively improve soil fertility, increase vegetable yields, and improve crop quality.

[0035] Therefore, this utility model embodiment provides a brand-new CO2 fertilizer generating device, that is, a new device that uses aerobic fermentation of agricultural waste to generate CO2 fertilizer, in order to provide the CO2 gas fertilizer required for greenhouse vegetable production.

[0036] Example:

[0037] Please see Figures 1-4 A novel device for generating CO2 fertilizer through aerobic fermentation of agricultural waste includes multiple insert rods 1 arranged in a circle around the same center point; at least four insert rods 1 are provided, and the multiple insert rods 1 are arranged in a circle with a geometric structure, which can be a regular polygon or other geometric shapes.

[0038] A vent plate 3 is fixedly connected to the inner side of the bottom end of the insertion rod 1. Multiple vent plates 3 are fixedly connected to the insertion rod 1 at one end, and the other ends are not intersected. The non-intersecting arrangement facilitates the movement of the insertion rod 1, making the structure of the insertion rod 1 not fixed.

[0039] A grate 2 is fixedly connected to the inner side of the upper middle end of the insertion rod 1. The grate 2 is a grate with expansion and contraction functions.

[0040] The upper outer side of the insertion rod 1 is fixedly covered with a sleeve 4, which is a sealing material such as plastic film.

[0041] Furthermore, in this embodiment, the grate 2 includes a fixing sleeve 201, a slide bar 202, and an elastic button 203;

[0042] One end of the slide rod 202 is fixed to the inner side wall of the insertion rod 1, and the other end is inserted into the inside of the fixing sleeve 201. At the same time, the other end of the slide rod 202 is fixedly snapped into the fixing sleeve 201 by the elastic button 203. One end of multiple fixing sleeves 201 is slidably connected to the slide rod 202, and the other end is arranged in a cross pattern. Multiple fixing sleeves 201 are located at the same height, and multiple insertion rods 1 are also located at the same height. The slide rod 202, in conjunction with the elastic button 203, performs multi-level telescopic adjustment within the fixing sleeve 201, thereby enabling the grate 2 to have expansion and contraction functions, so that the diameter of the overall device can be large or small.

[0043] Furthermore, in this embodiment, the breathable plate 3 includes a cut plate 301 and a connecting hole 302;

[0044] The cutting plate 301 is hollow inside, and one end of it is fixed to the inner side wall of the insertion rod 1; multiple connecting holes 302 are opened on the cutting back to communicate with its interior; the cutting surface of the cutting plate 301 is set downward, which makes it easier to cut the soil and facilitates the installation of the whole device.

[0045] Furthermore, in this embodiment, the insert rod 1 has a through hole 101 inside. The through hole 101 is connected to the connecting hole 302 through the inside of the cutting plate 301. Through the connection between the through hole 101 and the connecting hole 302, when the fermentation object is placed on top of the grate 2, the device can be exposed to air at the bottom, which facilitates the reaction.

[0046] Furthermore, in another embodiment, based on the above embodiment, the insertion rod 1 is segmented and telescopically extended by the rubber head bolt 5 and the inner sleeve telescopic rod 501. Both ends of the inner sleeve telescopic rod 501 are inserted into the through holes 101 of the insertion rod 1 in the upper and lower directions. One end of the inner sleeve telescopic rod 501 is fixed to the upper insertion rod 1, and the other end is threadedly connected to the insertion rod 1 by the rubber head bolt 5, locking it in the lower insertion rod 1. The inner sleeve telescopic rod 501 is hollow.

[0047] Specifically, when using it, first dig a hole in the soil inside the greenhouse so that the insertion rod 1 is inserted into the edge of the hole, the ventilation board 3 is supported at the bottom of the hole, the grate 2 is located at the opening of the hole, and the upper end of the insertion rod 1 is fixedly covered with a film 4, which is a plastic film or other sealing material.

[0048] Then cut 10 kg of dry straw into pieces about 20 cm long, mix it with about 30 kg of wet pig manure (moisture content 60-70%), and add water to make the moisture content of the mixture reach 60-70% (grab a handful of the mixture without draining the water, and when you clench your fist, water will drip out from between your fingers, at which point you can judge that its moisture content is 60-70%).

[0049] The mixture is then filled into grate 2 of the device to begin aerobic fermentation. The filling material should not be packed too tightly to avoid affecting aeration.

[0050] After the filling is completed, cover it with a layer of sponge, which will not affect the gas flow and can also keep it warm;

[0051] In addition, soaking the sponge in some dilute acid can absorb some NH3 and other gases, thus preventing the hazards caused by excessive NH3 concentration inside the greenhouse.

[0052] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural, procedural, or functional transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
