Problems solved by technology

Xiong Huawei reported in "Study on the Ecological Model of Rice Loach Comprehensive Planting and Breeding" (China Fisheries, 2017(7): 91-92) that loach was intercultured in rice planting fields, but the snail was not cultured. The reason may be that the snail artificial breeding technology has not been popularized

Embodiment 1

[0028] A method for ecological planting and breeding of snail, rice and loach co-cropped suitable for Guangxi area, comprising the following steps:

[0029] 1. Selection of planting ponds: The snail ecological breeding test field in Ligao Town, Liuzhou, Guangxi was selected as the experimental planting ponds, with an area of ​​667m2 for each planting pond 2 , aspect ratio 3:2. The water source is underground river water, clean and pollution-free, with a water temperature of 20°C all year round. The surrounding environment is quiet, leeward and sunny, not dry in case of drought, not flooded in case of waterlogging.

[0030] 2. Preparations before planting

[0031]2.1 Reconstruction of the breeding pond: Dig a ring ditch with a width of 1m and a depth of 0.5m along the inner side of the field ridge, and dig a longitudinal ditch with a width of 1m and a depth of 0.5m every 5m in the pond, and the two ends are connected to the ring ditch, which is convenient for feeding and dryi...

Embodiment 2

[0045] Contrast experiment: the comparison of comprehensive benefits between the ecological breeding of snails, rice and loach and the single culture of ring-edged snails:

[0046] 1. Experimental breeding pond and control breeding pond

[0047] 1.1 The experimental planting pond is the same as in Example 1.

[0048] 1.2 The control breeding pond is also the snail ecological breeding test field in Ligao Town, Liuzhou, Guangxi, next to the experimental breeding pond, and the area, water source, disinfection, fattening and other preliminary preparations are the same as the experimental breeding pond. The difference: there are no rings and longitudinal grooves in the culture pond, and the culture mode is the current main culture mode in the local area, that is, intensive culture of a single ring snail. The specific breeding patterns are shown in Table 1.

[0049] 2. Statistics and Analysis

[0050] The total output, average yield per mu, output value, etc. were calculated for ...

Abstract

The invention discloses an ecological planting and breeding method suitable for co-cultivation of snails, rice and loach in Guangxi area, that is, rice is planted in the snail culture pond and part of the loach is reared, and the rice is used to create a good habitat environment for the snails and loach , and purify the breeding water to reduce the occurrence of diseases; use loach to feed on large-scale bait that cannot be used by snails, and prey on the harmful organisms of rice to reduce the use of pesticides; use the remaining bait and excreted feces of snails and loach to replace rice topdressing, Reduce the use of chemical fertilizers and reduce production costs. The invention utilizes the symbiosis of snails, rice and loach to recycle the materials, improves the comprehensive income of snail culture, not only can provide high-quality raw materials of snails for "Liuzhou snail powder", but also avoids eutrophication of cultured water. The present invention adopts the ecological planting mode of snail-loach rice co-cultivation, and compared with the traditional mode of single-cultivation of snails in ponds, the profit per mu of ponds is increased by 2172 yuan, the profit rate is increased by more than 76%, and the economic benefits are remarkable.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an ecological planting and breeding method suitable for co-cultivation of snails, rice and loach in Guangxi. Background technique [0002] Ringed snails, commonly known as snails, stone snails, etc., are the most important and characteristic raw materials of the famous local snack "Liuzhou snail noodles", which directly affect the flavor and nutrition of snail noodles. In recent years, "Liuzhou snail powder" has been popularized nationwide, which has led to a sharp increase in the demand for snails as the main ingredient. In order to solve this problem, since 2018, artificial breeding of snails has been carried out in Guangxi, especially The Liuzhou region gradually spread it, but the main breeding mode is to use low-yield fields to carry out intensive cultivation of a single snail. The remaining feed and excreted feces during the breeding process continuously ent...
