Problems solved by technology

[0003] However, there is currently a problem regarding the impact of soil animals on soil greenhouse gas emissions: in field surveys, it is difficult to specifically clarify the effect of a certain group of soil animals on soil greenhouse gases, and the common method of collecting gas in the field is static chamber It is difficult to control the specific temperature and humidity, so it is difficult to elucidate the mechanism of action of soil animals on soil greenhouse gas emissions

specific Embodiment approach 1

[0019] Specific embodiment one: a kind of method of the indoor control experiment greenhouse gas collection based on soil animal and soil greenhouse gas relation research of the present embodiment, it is carried out according to the following steps:

[0020] 1. First collect 0cm-10cm surface soil in the area to be collected, and then pass through a 2mm sieve to remove plant residues, stones and large soil animals; cultivate at 65-70°C for 20-24 hours, and let it dry naturally for use;

[0021] 2. Weigh the air-dried soil in step 1 and put it into a jar, then add distilled water to reach 60% to 70% of the field water holding capacity; Cultivate in a wet incubator for 3 to 5 days;

[0022] 3. During the cultivation of soil samples in step 2, collect plants in the field; sterilize the collected plants with an autoclave, cut them into small pieces, and obtain the dry body of the living plant, then mix it with air-dried soil, and then add distilled water to reach 60 % to 70% of th...

specific Embodiment approach 2

[0025] Embodiment 2: This embodiment differs from Embodiment 1 in that: in step 2, the culture condition is 15° C. and the humidity is 16%. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0026] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the field water holding capacity in step 2 and step 3 is 65%. Others are the same as in the first embodiment.

Abstract

The invention discloses a method for interiorly controlling acquisition of experiment greenhouse gas based on soil animal and soil greenhouse gas relationship study, relating to a greenhouse gas acquisition method and aiming at solving the problems that currently, certain soil animals are difficult to determine the action on the soil greenhouse gas. The method comprises the following steps: acquiring a soil sample for airing and culturing, acquiring plant and treating and then mixing with aired soil, adding soil animals for culturing, and acquiring the gas. According to the method, under interior control experiments, the influence of specific soil animal population on the soil greenhouse gas emission provides a new method for correctly evaluating the influence of the soil animals on the emission characteristics of the soil greenhouse gas under global weather change background and accurately evaluating the gas emission quantity and the like; fertilizer application, addition of different species of animals and addition of different plant types can be conducted during treatment, and the multiple simulation functions of the soil utilization mode change can be solved; and the tools are simple, the operation is easy and the effects are obvious.

Description

technical field [0001] The invention relates to the field of soil ecology and specifically designs a method for studying the influence of soil animals on soil greenhouse gas emissions. Background technique [0002] Since the industrial revolution, the concentration of atmospheric greenhouse gases has increased sharply, and the global climate change caused by it has become the focus of attention at home and abroad. Soils are important sources and sinks of greenhouse gases, globally responsible for approximately 20% of CO 2 and 67% of N 2 O emissions come from soil. Although soil greenhouse gas emissions are small, they can significantly affect and change the global carbon and nitrogen balance and cycle, and the emission process involves multiple complex biological processes; for example, soil CO 2 Respiration from soil invertebrates, soil microbes and plant roots, N 2 O is mainly produced by soil nitrifying and denitrifying microorganisms. Studies have proved that soil a...
