Description
Technical Field
The invention belongs to the technical field of ecology, and relates to a method for performing carbon sequestration on plant materials by utilizing a natural low-temperature environment.
Background
With the background that the trend of global warming is becoming more and more significant, research on carbon sequestration technology is gradually rising worldwide and is rapidly developing. Carbon sequestration refers to the reduction of CO by storing carbon after it is harvested2And (4) discharge to the atmosphere. To date, radicalsCarbon sequestration technologies under various scenarios based on various principles are emerging, but many technical approaches remain to be explored.
Green plant pair CO2Is considered a natural, economical carbon sequestration process, whereas, in the natural ecosystem, CO is absorbed and assimilated by plants2In fact, it is a temporary sequestration and not a permanent fixation, because the trapped carbon is returned to the atmosphere by the action of the decomposer, only the time course of return is prolonged and the rate is slowed down. Thus, the photosynthetic carbon sequestration by green plants is only the first step in carbon sequestration, and long-term or persistent carbon sequestration approaches need to be further explored.
Under some natural conditions, relatively idle low-temperature environments (such as high-altitude and high-altitude areas, deep underground and deep underwater low-artificially-used low-temperature environments) naturally exist. If the low-temperature environment can be fully utilized to carry out carbon sequestration on plant materials, the method can become a technical approach with lower cost and wide prospect.
Disclosure of Invention
The invention provides a method for carrying out carbon sequestration on plant materials by utilizing a natural low-temperature environment, which comprises the following steps:
step 1: naturally drying the obtained plant material to be stored for a long time or artificially drying the plant material by a common method until the plant material has a safe water content (the safe water content needs to be determined by a conventional method for detecting the safe water content according to different plant materials), and then sterilizing and disinfecting the plant material by a conventional method.
Step 2: when the plant material subjected to the step 1 is irregular in shape and/or difficult to remould by a common conventional machine due to material or density, or when the space of the storage container is wasted in the process of loading the plant material into the storage container, the plant material needs to be processed and modified so as to fully utilize the space of the storage container when the plant material is loaded into the storage container.
The method for processing and modifying the plant material mainly comprises the following steps of compressing the plant material to increase the density of the plant material as much as possible: the shape of the plant material is subjected to regularization treatment (regularization treatment means that the shape of irregular plant material is changed into a regular shape so as to be convenient for storage and save space), so that the space of a storage container can be fully utilized when the plant material is loaded into the storage container; or crushing the different plant materials into small particles, so that the space of the storage container can be fully utilized when the plant materials are loaded into the storage container; after the plant material after processing and modification is loaded into the storage container, further space compression is still needed to ensure that the plant material is kept regular as much as possible in the storage container and the space is saved.

For example, in high latitude areas, the frozen layer with extremely low human utilization degree is below the frozen layer, namely the deep underground environment; in the middle and low latitude areas, the underground layer with low artificial utilization degree can be called as deep underground environment.
The deep underwater environment is not provided with a determined division standard and needs to be determined according to different regions, different human utilization degrees and different environmental parameter conditions.
