Bottomland transverse layered ecological disturbing comprehensive oncomelania-killing-resistant method
The invention provides a bottomland transverse layered ecological disturbing comprehensive oncomelania-killing-resistant method. The method comprises the following steps that 1, a first step for blocking oncomelania with the width being 2-8 m is dug downwards in the position, close to an embankment, of the bottomland in the side direction, the two ends of the step are kept being communicated with rivers and lakes, the elevation of the bottom of the first step is lower than the local perennial lower water level, and it is ensured that the continuous waterflooding time is up to eight months every year and the depth of water is greater than or equal to 1 m; 2, oncomelania-containing soil on the surface layer of a second step is wiped out, the depth is made to exceed 15 cm, non-oncomelania soil with the thickness up to 30 cm is covered on the second step, and the second step face layer is regular and flat and forms a gradient of 5-10 degrees with the beach face; and 3, the elevation of the top face of a third step is higher than the local highest oncomelania-containing altitude traverse, and the width of the top face is added to be greater than or equal to 1 m. According to the bottomland transverse layered ecological disturbing comprehensive oncomelania-killing-resistant method, the defects of easy relapse and environmental pollution of existing drug molluscacidal and other methods are overcome, and the method has the advantages of being broad in application range, large in oncomelania treatment area, good in oncomelania-killing-resistant effect, flexible in utilization and the like.
