Problems solved by technology

[0004] The invention aims to solve the problems in the prior art that the sphagnum moss purification bed in the degraded riverside wetland in the cold region survives the winter under conventional open-air conditions, and the spore germination rate is low and the recovery time is late, and provides a kind of overwintering for the sphagnum moss purification bed in the degraded riverside wetland in the cold region method

specific Embodiment approach 1

[0029] Specific implementation mode one: the method for overwintering the sphagnum moss purification bed of wetland along the river degraded in the cold area described in the present implementation mode, is carried out according to the following steps:

[0030] Step 1: Digging and placement

[0031] In the area 3 to 7 meters away from the waterway or water bubble in the wetland, and where there are sedges and willows distributed, use a shovel to dig out a columnar pit, and first place sedges with a thickness of 2 to 10 cm on the bottom of the pit. Then place the sphagnum moss barrel in the center of the pit, and finally fill the gap between the sphagnum moss barrel and the columnar pit with sedge; the internal water channel in the wetland is a water flow channel formed by a river crossing the wetland;

[0032] Step 2: Lay marsh willow-sex mulch

[0033] After step 1 is completed, evenly place a layer of sedge with a thickness of 1 to 2 cm on the upper part of the sphagnum mos...

specific Embodiment approach 2

[0040] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the peat moss purification bed is the peat moss barrel, which is prepared according to the following steps:

[0041] Punch holes around and at the bottom of the polyethylene bucket, and then transplant peat moss into the polyethylene bucket. The planting density of peat moss is 5-15 plants / cm 2 , that is, the preparation of the peat moss purification bed is completed. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0042] Embodiment 3: This embodiment is different from Embodiment 1 or 2 in that: in step 1, first place the sedge with a thickness of 6 cm at the bottom of the pit, and then place the peat moss barrel in the center of the pit. Others are the same as in the first or second embodiment.

Abstract

The invention discloses an overwintering method for a sphagnum purification bed of a degraded riverside wetland in a cold region, relates to an overwintering method for a sphagnum purification bed and aims to solve the problems of low spore germination rate and late recovery time when the sphagnum purification bed of the degraded riverside wetland in the cold region overwinters under the conventional outdoor condition in the prior art. According to the method, 1, a columnar pit is dug near an inner water channel or a small lake of the wetland, and a sphagnum barrel is put in the center of the columnar pit; 2, a salix brachypoda-sedge covering layer is paved at the upper part of the sphagnum barrel; 3, piles are put on the periphery of an upper opening of the columnar pit, and a wheatgrass layer is poured. By means of the method, the spore germination rate of the sphagnum purification bed after overwintering is increased, and the recovery time of sphagnum is shortened. The method is used for overwintering and recovery of the sphagnum purification bed of the degraded riverside wetland in the cold region.

Description

technical field [0001] The invention relates to a method for overwintering a peat moss purification bed. Background technique [0002] In my country, wetlands (freshwater swamps) can only be seen in floodplains, and most of them belong to protected areas. However, due to human destruction and water pollution in the lower reaches of the Songhua River, the wetlands along the river were severely damaged, and the water purification function was seriously degraded. As a "super sponge", peat moss (Sphagnum) not only has an important carbon sequestration function, but also can be used as an excellent moisturizing material and toxic chemical adsorbent. Therefore, the subject group has built a certain number and scale of peat moss purification beds or floating beds in the degraded wetlands along the lower reaches of the Songhua River, and has put them into use, which can effectively restore the damaged wetland ecosystem and efficiently remove nutrients (carbon , nitrogen, phosphoru...
