The invention discloses a method for quickly treating
wetland edge water and
soil loss by using
sonchus brachyotus, which comprises the following steps: 1) performing field exploration, and determining the bare soil area and gradient of a to-be-treated region; 2) summarizing and analyzing data, and dividing and grading a target governance area; 3) planting
sonchus brachyotus: planting
sonchus brachyotus in the target treatment area according to the determined area gradient, bare soil area and grading of the target treatment area; and 4)
continuous monitoring and timely reseeding are carried out, so that the continuity of the number of sonchus brachyotus plants in the target treatment area is ensured. According to the method disclosed by the invention, by utilizing the characteristics that root systems of the sonchus brachyotus can fix soil, reduce
erosion, absorb and accumulate
soil nutrients and improve
soil quality, the sonchus brachyotus is reasonably and densely planted at the edge of the
wetland, so that the rapid effect of treating water and
soil loss of the
wetland is realized; the method has the advantages of low cost, good effect, simplicity and convenience in operation and the like, and is suitable for rapid treatment and
recovery of water and
soil loss caused by early damage of a wetland
ecosystem.
