specific Embodiment approach 1
[0021] Specific embodiment one: the method for taking the peat column core of peatland in winter in this embodiment is carried out according to the following steps:
[0022] 1. The peat core collection time is set in the early winter season, and the freezing depth of the peat surface is 5-15cm;
[0023] 2. Along the cross-section of the peatland, use the probe rod to detect the thickness of the peat above the permafrost layer of the peatland (you can judge the length of the probe rod when touching the bottom of the peat and feedback the hard touch), and select the peat at the corresponding depth according to the research purpose as a sample point;
[0024] 3. Plane off the frozen ice layer on the peat surface of the sample point, select a 20cm×20cm square area as the pre-sampling area, cut vertically downwards along the square sideline with a saw, until the permafrost layer, after sawing all four sides, get a 20cm ×20cm×h peat core;
[0025] 4. Dig a deep pit larger than 20c...
specific Embodiment approach 2
[0029] Embodiment 2: This embodiment differs from Embodiment 1 in Step 1 when the freezing depth of the peat surface layer is 10 cm. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0030] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in step 3, an iron pick is used to plan off the frozen ice layer on the peat surface of the sample point. Others are the same as those in the first or second embodiment.
