Problems solved by technology

In recent years, due to the sharp 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 has been expanding. However, due to the special biological characteristics of crayfish, it is easy to form crayfish mating and breeding in the same rice field.
The greenhouse output of Chinese tortoise is increasing year by year, but the quality and quality are not good, and the market sales are weak

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...

Embodiment 2

[0056] The homemade crayfish fermentation material is prepared as follows: 12 parts of soybean meal, 8 parts of corn, 9 parts of rapeseed meal, 8 parts of potato, 4 parts of sesame cake, 4 parts of thousand-head fish meal, 4 parts of crayfish meal, 3 parts of germinated shrimp rice, japonica rice, 3 parts of southern japonica germ rice with shrimp rice, 4 parts of shrimp rice bran, 4 parts of April green soybeans planted on the ridge of shrimp rice field, 4 parts of rice and shrimp powder, 4 parts of blue crab shell powder, 4 parts of selenium-enriched broccoli, selenium-enriched 4 parts of Sophora japonica, 4 parts of river clam, 3 parts of calcium dihydrogen phosphate, 3 parts of osmanthus seed oil, 1 part of tea seed oil, mechanically stir the above ingredients evenly; prepare appropriate amount of tap water for 2-3 days, add lactic acid bacteria , Bacillus, and yeast compound preparations. Use a special sprayer to evenly spray the compound strains on the raw materials and s...

Embodiment 3

[0061] The homemade crayfish fermentation material is prepared as follows: 15 parts of soybean meal, 5 parts of corn, 5 parts of rapeseed meal, 10 parts of potato, 5 parts of sesame cake, 3 parts of thousand-head fish meal, 3 parts of crayfish meal, 5 parts of germinated shrimp rice, japonica rice, 2 parts of shrimp rice south japonica germ rice, 3 parts of shrimp rice bran, 5 parts of April green soybeans planted on the ridge of shrimp rice field, 3 parts of rice and shrimp powder, 5 parts of blue crab shell powder, 5 parts of selenium-enriched broccoli, selenium-enriched 5 parts of Sophora japonica, 5 parts of river clam, 2 parts of calcium dihydrogen phosphate, 2 parts of osmanthus seed oil, 2 parts of tea seed oil, mechanically stir the above ingredients evenly; prepare appropriate amount of tap water for 2-3 days, add lactic acid bacteria , Bacillus, and yeast compound preparations. Use a special sprayer to evenly spray the compound strains on the raw materials and stir ev...

Abstract

The invention discloses a method for ecological breeding of lobsterling and chinemys reevsii and directive breeding of lobsterling seeds. The method comprises the following steps of: S1: constructinga rice lobsterling and grass tortoise integrated culture region, a lobsterling seed rearing region and a chinemys reevsii temporary rearing region, and separating each region by meshes; S2: carrying out space-time unification in the rice lobsterling and grass tortoise integrated culture region, clearing away residual lobsterling by utilizing chinemys reevsii, and reselecting parents from differentplaces; S3: in the same space and at different time, feeding a home-made lobsterling fermented material to cultivate a crop of adult lobsterling; S4: before chinemys reevsii leaves from a greenhouse,a feeding homemade chinemys reevsii fermented material; S5: stopping feed feeding, inducing chinemys reevsii which is mildly hungry to clear away residual lobsterling in a rice field; and S6: feedingchinemys reevsii baits in the chinemys reevsii temporary rearing region, slowly reducing a water level in the rice lobsterling and grass tortoise integrated culture region and enabling chinemys reevsii to seek smell to enter the temporary rearing region. The method achieves an effect that the same rice field meets different demands for growth of rice lobsterling and grass tortoise; and the residual lobsterling in the rice field is cleared away, and directive breeding of lobsterling seeds is implemented.

Description

technical field [0001] The invention relates to the technical field of crayfish and Chinese tortoise paddy field cultivation and crayfish seed selection, in particular to a method for ecological cultivation of crayfish and Chinese tortoise and directional selection of crayfish seedlings. Background technique [0002] Crayfish belong to Arthrophyta, Crustacea, Crawfishidae, Procambarus genus, also known as crayfish, scientific name Procambarus clarkii (hereinafter collectively referred to as crayfish), its meat is delicious and nutritious, and it is deeply loved by people. It is the main species of shrimp farming at present. In recent years, due to the sharp 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 has been expanding day by day. However, due to the special biological characteristics of crayfish, it is easy to form crayfish mating and breeding in the ...
