Embodiment 1
[0038] The method for the ecological breeding of crayfish and Chinese tortoise and the directional selection of crayfish seedlings comprises the following steps:
[0039] Step 1: Construct the co-cultivation area for rice, shrimp and tortoise, the breeding area for crayfish fry, and the temporary breeding area for Chinese tortoise. Each area is separated by mesh to realize the diversification of rice field functions;
[0040] The space-time distribution combination of rice, shrimp, tortoise and 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 rice, shrimp, tortoise growth ( figure 1 Rice, shrimp, tortoise, and rice field zoning transformation diagram): In the rice, shrimp, and tortoise joint farming area, crayfish farming is the main focus from March to June; rice seedling planting and rice management are the main focus from June to July; Until October, the ric...
