The invention relates to a method for killing oncomelania with rape of high content of sulfuric glucoside. It comprises following steps: planting said rape with high content of sulfuric glucoside around river bench and lake where it is easy for oncomelania to grow and breed, establishing a growing belt of said rape with its length being 1- 10 meters, planting vegetable seed with its density being 5- 10 per square meter and with its distance being 0.5- 2 meter away from water, and harvesting it after germination, blooming and producing fruit. The density will be increased through rape seed 's continuous and natural growth, and the biological community with rape being main variety can be got after 1- 3 years' growth, and the oncomelania can be isolated. The ecological method for killing oncomelania can overcome the shortcomings of chemical and current biological method, and it is characterized by simple operation, reduced production cost, natural and cyclical growth all around the year, part restoration of ecological environment, and good result of plan pollution under control and landscape construction along river bench and lake. |
