Method for recovering slightly degraded Calamagrostis angustifolia wetland by using farmland backwater
A wetland and leaflet technology, applied in fertilization methods, botanical equipment and methods, agriculture, etc., can solve the problems of lack of vegetation restoration techniques and methods, single and extensive technical means, and poor restoration effects, so as to improve the regional ecological environment, The effect of protecting species diversity and increasing dominance

Embodiment 1
[0015] A method for recovering slightly degraded wetlands of P. chinensis by utilizing farmland dewatering, the steps are as follows:
[0016] Step 1: Diagnosis of the degree of degradation of the wetlands of A. microphyllum. The coverage index of the dominant species in the community (Chapteria chinensis) is used to measure the degree of degradation of the wetland. The coverage of the dominant species is 50% to 70% in the wetlands of mildly degraded Cinnamomum palisana, and the coverage of the dominant species in the wetlands of moderate degeneration. In 30% to 50%, the coverage of the dominant species in the heavily degraded wetlands of A. microphyllum was 10% to 30%.
[0017] Step 2: Determine the soil nitrogen limitation factor of the degraded P. baicalensis wetland. The nitrogen limitation factor was measured by soil N:P. The specific operation method is as follows. First, measure the total nitrogen and total phosphorus content of the wetland soil (depth 0 ~ 20cm); seco...

[0029] A method for recovering slightly degraded wetlands of P. chinensis by utilizing farmland dewatering, the steps are as follows:
[0030] Step 1: Diagnosis of the degree of degradation of the wetlands of A. microphyllum. The coverage index of the dominant species in the community (Chapteria chinensis) is used to measure the degree of degradation of the wetland. The coverage of the dominant species is 50% to 70% in the wetlands of mildly degraded Cinnamomum palisana, and the coverage of the dominant species in the wetlands of moderate degeneration. In 30% to 50%, the coverage of the dominant species in the heavily degraded wetlands of A. microphyllum was 10% to 30%.
[0031] Step 2: Determine the soil nitrogen limitation factor of the degraded P. baicalensis wetland. The nitrogen limitation factor was measured by soil N:P. The specific operation method is as follows. First, measure the total nitrogen and total phosphorus content of the wetland soil (depth 0 ~ 20cm); seco...
