Embodiment 1

[0029] Embodiment 1 A kind of control method of apple snail

[0030] The control methods of apple snails include: (1) Invasion and interception: set up fence nets at the water inlet of the pond, and plant red dragon grass around the pond; (2) Trapping: set up vertical strips in the middle and around the pond with The snail-catching net of the wooden spiral channel, planted around the snail-catching net to plant the apple snail and hibiscus; (3) Preparation of oleander and hibiscus powder: 1. Dry and crush the fresh leaves of oleander in an oven at 45 ° C, and use n-hexane Extract after dissolving, then centrifuge and spin dry into powder; 2. Dry the whole hibiscus hibiscus in an oven at 45°C, pulverize it, and pass through a 30-mesh sieve; 3. Take oleander powder and hibiscus powder in a mass ratio of 2:1; ( 3) Treatment of plant secondary biomass: put 30g of oleander and hibiscus powder mixture into each low-lying place of the pond.

Embodiment 2

[0031] Embodiment 2 A kind of control method of apple snail

Abstract

The invention discloses a preventing and controlling method of ampullaria crossean. The preventing and controlling method is characterized by comprising the steps of 1, invasion interception, wherein a block is arranged at a water inlet of a water pond, and plants with a repellent effect of ampullaria crossean are planted around the water pond; 2, trapping and killing, wherein ampullaria crossean catching nets are arranged in the middle and the periphery of the water pond, and plants with the attracting effect of ampullaria crossean are planted around the ampullaria crossean catching nets; 3, plant secondary substance control, wherein a powder mixture of nerium indicum and hibiscus is thrown at the low-lying position of the water pond. According to the preventing and controlling method of ampullaria crossean, by utilizing the ecological habit of ampullaria crossean to conduct prevention and control, a better preventing and controlling effect is achieved; the plant source secondary substance is adopted to prevent and control ampullaria crossean, and the preventing and treating method is safe to the environment and other aquatic life, is an environment-friendly and efficient preventing and controlling method, and is suitable for being applied and popularized in prevention and control of ampullaria crossean.

Description

technical field [0001] The invention relates to the technical field of ecological prevention and control, in particular to a method for preventing and controlling apple snails. Background technique [0002] Apple snail (Pomacea canaliculata), also known as the big bottle snail, is native to the Amazon River Basin in South America. Apple snails were introduced to Taiwan, China in the 1970s, and were introduced to Guangdong by Brazilian Chinese in 1981. After 1984, apple snails have been widely cultivated in Guangdong. It was released into the wild due to over-farming, coupled with a bad taste. Apple snails have a strong ability to adapt to the environment and reproduce quickly, so they spread rapidly in rivers, lakes and fields; their large appetite and variety of food can damage the growth of food crops, vegetables and aquatic crops. Harmful animals in Yunnan, Zhejiang, Shanghai, Jiangsu and other places. In the vast area south of the Yangtze River, apple snails can surv...
