Ecological method for controlling apple snails in rice field through tea seed cakes and full-process two-section system for raising ducks in rice field

Abstract

The invention discloses an ecological method for controlling apple snails in a rice field through tea seed cakes and a full-process two-section system for raising ducks in the rice field. The method comprises the following steps of spreading 45-55 kg, preferably 50kg, of tea seed cakes per mu in a period before planting and after plowing; using a nylon net with the height of 0.8-1.2 m, preferably1 m, for circumventing the rice field to provide convenience for breeding ducks and controlling the migration of apple snails and yellow weasels from the outside; 10 days after planting, putting the first batch of rice field ducks into the rice field on a sunny day and utilizing the ducks to swallow eggs of apple snails and young snails on ridges, weeds and rice plants, wherein large snails migrated into the rice field are eliminated by the ducks with the growth of the ducks; after heading of rice, removing the first batch of stocking ducks from the rice field to prevent the large ducks from damaging ears, wherein the second batch of ducks are required to be hatched at the end of tillering of the rice, and the second batch of ducks are put into the rice field after a heading stage to continue to swallow eggs of apple snails and small snails. The method not only can obviously reduce the snail control cost and increase the economic benefit, but also ensures that the ducks and the rice which are raised by the rice field are not contaminated by pesticide and herbicides and are safer.

Description

technical field [0001] The invention relates to an ecological method for systematically controlling apple snails in paddy fields in the whole process of raising ducks in paddy fields by using tea seed cakes and two-stage duck raising. Background technique [0002] Apple snail is a new pest, and its morphological characteristics and shell appearance are similar to those of field snails. It has a spiral shell, the color varies with the environment and the age of the snail, it is shiny and has several thin longitudinal lines, and the head and abdomen protrude when crawling. The head has 2 pairs of antennae, the front antennae are short, the rear antennae are long, and there is an eye outside the base of the rear antennae. There is a thick lung suction pipe on the left side of the spirochete. Adult shells are thick, shell height is 7cm, young shells are thin, the suture line of the shells sinks into shallow grooves, and the navel of the shells is deep and wide. Shellfish herm...

Problems solved by technology

[0020] (1) Ineffective killing of Honda overwintering snails;

[0021] (2) There is no blocking and controlling the reproduction of apple snails that migrate to rice fields after transplanting;

[0022] (3) Ineffective control and killing of apple snails outside rice fields;

[0023] (4) The shell after death will not be reduced and will harm people
