How to apply carbon dioxide fertilizer in the greenhouse? Method for releasing carbon dioxide fertilizer in greenhouse cultivation

How to apply carbon dioxide fertilizer in greenhouse cultivation? There are many methods for applying carbon dioxide fertilizer in greenhouse cultivation, such as the application of "dry ice" method, the application of organic fertilizer method, soil pellet gas fertilizer, cylinder method, etc., but these methods have their own shortcomings, the specific contents are as follows.

1. Cast the "dry ice" method: that is, release solid carbon dioxide. The solid carbon dioxide is sublimated in the shed and turned into gaseous carbon dioxide for absorption; advantages: simple operation, easy control, and sufficient gas volume; disadvantages: high cost, poor safety, strict storage and transportation conditions (requires refrigerated transportation and storage).

2, cylinder method: mainly using the tail gas of the brewing industry, the carbon dioxide is purified and collected into the cylinder, can be directly applied in the greenhouse; advantages: gas purity, gas volume; shortcomings: one-time investment, transportation inconvenience.

3. Adding organic fertilizer method: by adding organic fertilizer, using microbial fermentation to produce carbon dioxide; advantages: raw materials can be taken locally, and the cost is low; disadvantages: slow gas production, uncontrollable gas volume, easy to produce harmful gases such as ammonia.

4, combustion method: mainly burning natural gas, liquefied gas, biogas, honeycomb coal and other fuels to produce carbon dioxide gas; advantages: large gas supply, easy to operate; disadvantages: large infrastructure investment, difficult to control gas volume, easy to produce carbon monoxide, sulfur dioxide Harmful gases are harmful to the growth of vegetables.

5, chemical method: the use of carbonate and acid in the plastic barrel reaction to produce carbon dioxide: advantages: low cost, fast gas production; Disadvantages: the operation method is not easy to master, improper operation can cause damage to people and crops, poor safety.

6. Soil granules and gas fertilizers: The products include: “double micro”, carbon dioxide granule gas fertilizer, etc., which is a kind of biogas fertilizer obtained by using microbial resources and using industrial microbial fermentation technology. After being applied to the soil, it can produce carbon dioxide gas. Advantages: safe and reliable, easy to use, no need for energy and accessories, no special equipment, small application, convenient storage and transportation, no toxicity, no pollution to the environment, and can also improve the soil; disadvantages: soil Maintain a certain humidity.
