Embodiment Construction

[0081] 1. A specific embodiment. In the area of ​​water network, harden the ditches with snails with a snail-killing pad. Small ditches can be hardened on three sides with impermeable nut-killing pads, and large main canals and branch canals can be hardened on both sides. When hardening, it is only necessary to remove large plants and other obstacles, simply level the ground, and cover it with a nut-killing pad.

[0082] 2. A specific embodiment. For rivers, rivers, lakes, ponds, banks, rivers, etc., where the water level does not change much, if there are snails distributed, remove larger plants and obstacles, and after the ground is simply leveled, use the snail killer pad along the direction of the water level line, and in the direction of the water level line. Overlay laying. If the water level fluctuates slightly, it can be covered and laid at appropriate locations according to the distribution of oncomelania and changes in the water level.

Abstract

The invention relates to a method and a device for killing snails. By applying a. a snail killing pad for restraining plant growing and preventing snails from getting in and out of earth, b. a snail breeding ground with large water change, and a separation device, the snails are prevented from moving with water level so as to obtain a suitable breeding environment and further kill the snails; By covering the snail killing pad, the snails can not obtain necessary wet earth for living and vegetation for hiding and eating. During flood season, the separation device can prevent the snails on water side from moving with the water level and cause the snails to be drowned; during water withdrawal, the snails can not move with water level to a suitable breeding ground due to the existing of the separation device and then die. The separation device can be a separating channel, floating separating matters, as well as separating nets, separating boards or separating cloth with fixed support structures. According to different environments and snail breeding grounds, the snail killing pad and the separation device, or the snail killing pad and the separation device can be adopted for killing the snails. The snail killing pad, the floating separation device, etc. can contain drugs for killing and expulsing snail and other drugs.

Description

1. Technical field: [0001] The invention relates to a method and facility for killing snails, intermediate hosts of schistosomes. 2. Technical background: [0002] Schistosomiasis is a parasitic disease that seriously endangers people's health. In my country, oncomelania is the only intermediate host of Schistosoma japonicum. Elimination of snails can reduce or even eliminate the harm of Schistosoma japonicum to people. [0003] Oncomelanias in schistosomiasis endemic areas in mainland my country can be divided into two types according to their appearance. One is rib-shell snails, which are mainly distributed in water networks and lakes and swamps; the other is light-shell snails, which are mainly distributed in mountainous and hilly areas. Methods such as environmental modification and drug molluscicide are often used to kill snails. Environmental improvement is mainly to change the environment of the oncomelania breeding area in combination with the construction of far...
