specific Embodiment approach 1
[0019] Specific implementation mode one: (see attached figure 1 ) The organic carbon mineralization cultivation device of this embodiment is composed of a biochemical cultivation pin 1, a valve 2, a rubber stopper 3, a connecting pipe 4, and a jar 5; wherein in the organic carbon mineralization cultivation device, the connecting pipe 4 penetrates the rubber stopper 3. The end of the connecting pipe 4 located at the larger side of the bottom of the rubber stopper 3 is connected to the biochemical culture pin 1 through the valve 2, and the rubber stopper 3 is covered on the mouth of the jar 5.
specific Embodiment approach 2
[0020] Specific implementation mode two: the present embodiment utilizes the method for soilless measurement of soil organic carbon mineralization rate by the organic carbon mineralization cultivation device, specifically completes according to the following steps:
[0021] 1. Take 2 sets of organic carbon mineralization cultivation devices A and B;
[0022] 2. Determination of soil moisture content. According to the moisture content, the volume ratio of dry soil mass to distilled water is 1g: 4.5~5.5mL. Weigh the soil and distilled water, add the weighed soil and distilled water to the beaker and stir it magnetically for 30 minutes, then use 2900 After centrifugation at ~3100rpm for 5min, take 5% of the supernatant by volume as the microbial inoculum; filter the remaining supernatant through a 0.45μm filter membrane to obtain a water-soluble organic carbon mother liquor;
[0023] 3. According to the volume ratio of microbial inoculum and water-soluble organic carbon mother li...
specific Embodiment approach 3
[0028] Specific embodiment three: the difference between this embodiment and specific embodiment two is that in step two, the soil and distilled water are weighed according to the volume ratio of dry soil mass to distilled water is 1g: 4.8-5.2mL. Others are the same as in the second embodiment.
