Problems solved by technology

"Xinglin Killing Molluscs", using a variety of snail-killing plants to artificially build ecological forests, is a new method of mollusc control in recent years, but there are still many problems, that is, how to grow these kinds of plants faster and better a difficult problem

Embodiment 1

[0015] Put the fresh high glucosinolate rapeseed plants into a 0.1×0.1 meter isolation zone and place them near the end of a long slot, put 100 live snails in the slot, and put a small amount of niclosamide at a distance of 3 meters from the snails as a Repellant, after 24 hours of observation, no snails were found to cross the high glucosinolate rape isolation zone and enter the other end, and the oncomelania basically stayed about 0.5 meters away from the high glucosinolate rape isolation zone.

Embodiment 2

[0017] In the experimental field, a 1-meter rape barrier was planted around a 5×5-meter pond. The peak growth season in May is also the oncomelania breeding season. Take 1000 snails and put them into the pond. After a month of observation, no snails were seen to climb out of the bank over the growth zone of high glucosinolate rapeseed.

Abstract

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.

Description

technical field [0001] The invention relates to a method for killing oncomelania, in particular to the construction and method of an ecological system for killing oncomelania with high glucosinolate rapeseed. Background technique [0002] Oncomelania hupensis is the only intermediate host of schistosomiasis and an indispensable link in the transmission of schistosomiasis. After the miracidium of schistosomiasis invades the snail, it can develop into a mother spore, which multiplies thousands of times in the snail, and continuously produces The cercariae are in the water or the moist soil surface, and even infect humans and other animals. This cycle has contributed to the spread and spread of schistosomiasis. At present, the molluscicide effect is good, and the most widely used chemical molluscicides are high-efficiency sodium pentachlorophenate (pentachlorophen 01) screened out in 1955 and niclosamidum (niclosamidum), which appeared in the early 1960s. It is used in many cou...
