specific Embodiment approach 1
[0016] Specific implementation mode one: In this implementation mode, the method for transforming the abandoned fishpond in the soda saline-alkali land into a cattail wetland is carried out according to the following steps:
[0017] 1. Desalination of abandoned fish ponds and micro-landscape modification: Drain the abandoned fish ponds to be transformed into cattail wetlands, remove weeds, inject fresh water into the abandoned fish ponds, and turn the soil with a tiller at the same time to reduce the salt content of the soil Drain the water in the fish pond after 0.47%; then harrow the field with a rotary tiller;
[0018] 2. Collection and processing of cattail rhizomes: select strong cattails with strong reproductive ability, dig out the underground rhizomes of cattails, remove the top leaves, and then immerse the roots of cattails in water;
[0019] 3. Transplanting cattail rhizomes: Inject fresh water into the modified fish pond in step 1, the water depth is 1-5cm, and then...
specific Embodiment approach 2
[0026] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in Step 1, the depth of the rotary cultivator harrowing the field is 15-20 cm. Other steps and parameters are the same as those in Embodiment 1.
specific Embodiment approach 3
[0027] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the row spacing and plant spacing of transplanting cattail rhizomes in step 3 are 10-20 cm, and the depth of entry into the soil is 5-8 cm. Other steps and parameters are the same as those in Embodiment 1.
