Embodiment 1

[0066] Six flat rectangular paddy fields with good ecological environment and no pollution sources in Quanjiao County, Anhui Province were selected, with an aspect ratio of 2:1, and each paddy field was about 20 mu.

[0067] (1) Construct rice, shrimp and soft-shelled turtle co-cultivation area, crayfish fry breeding area, and Chinese soft-shelled turtle temporary breeding area, and separate each area with mesh to realize the diversification of rice field functions

[0068] The space-time distribution combination of rice, shrimp and soft-shelled turtle co-cropping paddy fields, in different spaces at the same time, or in different time periods in the same space, realizes that the same paddy field can meet the different needs of the growth of rice, shrimp and soft-shelled turtles. In the area where rice, shrimp and soft-shelled turtles are co-cultivated, from March to June, crayfish farming is mainly used; from June to July, rice seedling planting and rice management are mainly ...

Embodiment 2

[0083] Six flat rectangular paddy fields with good ecological environment and no pollution sources were selected in Huoqiu area, Anhui Province, with an aspect ratio of 2:1, and each paddy field was about 25 mu.

[0084] (1) Construct rice, shrimp and soft-shelled turtle co-cultivation area, crayfish fry breeding area, and Chinese soft-shelled turtle temporary breeding area, and separate each area with mesh to realize the diversification of rice field functions

[0085] The space-time distribution combination of rice, shrimp and soft-shelled turtle co-cropping paddy fields, in different spaces at the same time, or in different time periods in the same space, realizes that the same paddy field can meet the different needs of the growth of rice, shrimp and soft-shelled turtles. In the area where rice, shrimp and soft-shelled turtles are co-cultivated, from March to June, crayfish farming is mainly used; from June to July, rice seedling planting and rice management are mainly used...

Embodiment 3

[0100] Six flat rectangular paddy fields with good ecological environment and no pollution sources were selected in Dingyuan, Anhui Province, with a length-to-width ratio of 2:1, and each paddy field was about 30 mu.

[0101] (1) Construct rice, shrimp and soft-shelled turtle co-cultivation area, crayfish fry breeding area, and Chinese soft-shelled turtle temporary breeding area, and separate each area with mesh to realize the diversification of rice field functions

[0102] The space-time distribution combination of rice, shrimp and soft-shelled turtle co-cropping paddy fields, in different spaces at the same time, or in different time periods in the same space, realizes that the same paddy field can meet the different needs of the growth of rice, shrimp and soft-shelled turtles.

Abstract

The invention provides a method for ecologically breeding rice, crayfishes and turtles in a rice field and directionally breeding the crayfishes. By utilizing a biological characteristic that Chinesesoftshell turtles like eating the crayfishes according the chance of collaboration of the same time and same space, the residual crayfishes in the rice field are cleared, so that mating and reproduction of the crayfishes in the same rice field are prevented. On the other hand, allopatric crayfish parents are selected again, so that the directional optimized breeding of the crayfishes is realized.The method specifically comprises a method for directionally breeding the crayfishes, a method for ecologically breeding the rice, the crayfishes and the turtles, a method for producing crayfish feeds, a method for producing Chinese softshell turtle feeds and a method for producing Chinese softshell turtle baits. By implementing the method provided by the invention, the quality of the crayfishes and the Chinese softshell turtles can be improved, and high-quality rice is harvested, so that the mu production value is increased.

Description

technical field [0001] The invention relates to paddy field cultivation of crayfish and Chinese soft-shelled turtle, specifically including a method for directional breeding of crayfish, a method for ecological breeding of rice shrimp and soft-shelled turtle, a method for making crayfish feed, a method for making feed for Chinese soft-shelled turtle, and a method for making bait for soft-shelled soft-shelled turtle. field of farming technology. Background technique [0002] Crayfish belong to the phylum Arthropoda, Crustacea, Crawfishidae, and the genus Procambarus, also known as crayfish. It is loved by people and is the main species of shrimp farming at present. In recent years, due to the increase in market demand, the natural resources of crayfish have decreased sharply, and the price has gradually increased. The scale of farming crayfish in rice fields is expanding day by day, but due to the special biological characteristics of crayfish, it is easy to form inbreeding...
