Problems solved by technology

[0003] At present, there are still some deficiencies in the existing rice shrimp and crab breeding, for example; the existing rice shrimp and crab breeding does not organically combine shrimp and crab farming with rice planting, so that the two are mutually beneficial and symbiotic and give full play to the advantages of farmland. Productivity slows down the growth rate of shrimp and crabs, and the survival rate of shrimp and crabs is relatively average, which reduces the utilization rate of farmland management, output benefits and the effect of improving the ecological environment

Embodiment 1

[0039] The mixed ecological planting and breeding method of high-quality rice, shrimp and crab comprises a paddy field 1, the inner side of the paddy field 1 is provided with a shrimp and crab breeding ditch 3, and the inner periphery of the shrimp and crab breeding ditch 3 is provided with a rice planting area 2, so that The paddy field 1 bank is provided with shielding plate 4.

[0040] The breeding steps are as follows:

[0041] a. Select a paddy field 1 with good water quality, sufficient water volume, no pollution sources around, strong water retention capacity, convenient drainage and irrigation, and not subject to flooding, and open a shrimp and crab breeding ditch 3 inside the paddy field 1, and then fix the shielding plate 4 on the paddy field on the bank of 1;

[0042] b. After step a is completed, clean up the silt in the shrimp and crab breeding ditch 3, and after drying for 3-4 days, pour water into the paddy field 1, and then transplant aquatic plants in the shr...

Embodiment 2

[0052] Embodiment two rice shrimp and crab breeding data parameter table 3 is as follows:

[0053] Test items Survival rate growth rate rice yield Pest load Parameter index high quick excellent few

[0054] To sum up, referring to the comparison of the data in Table 1, Table 2 and Table 3, it can be concluded that the mixed ecological breeding mode of shrimp and crab rice fields can organically combine shrimp and crab farming with rice planting, so that the two can coexist mutually beneficially and give full play to the productivity of the farmland. It accelerates the growth rate of shrimp and crab, increases the survival rate of shrimp and crab during growth, improves the utilization rate and output benefit of farmland management, and provides shelter and food for shrimp and crab during the growth of rice, and the excrement produced by shrimp and crab It provides good biological fertilizer for rice growth and improves the effect of improving...

Abstract

The invention discloses a mixed ecological cultivation method of high-quality rice shrimps and crabs. According to the method, a rice field is included, a shrimp and crab breeding ditch is arranged onthe inner side of the rice field, a rice planting area is arranged on the inner periphery of the shrimp and crab breeding ditch, and baffle plates are arranged on the bank sides of the rice field. Bymeans of the mode of mixed ecological shrimp and crab cultivation in the rice field, shrimp and crab cultivation and rice planting can be organically combined to realize mutualistic symbiosis, productivity of the farmland is given full play, the growth rate of the shrimps and crabs is increased, the survival rate of the shrimps and crabs at the growth stage is increased, the utilization rate andoutput benefits of farmland management are increased, besides, shelters and food are provided for the shrimps and crabs in the rice growth process, feces produced by the shrimps and crabs provide goodbio-fertilizer for rice growth, and therefore, the ecological environment is improved.

Description

technical field [0001] The invention relates to the technical field of shrimp and crab breeding, in particular to a mixed ecological breeding method for high-quality rice shrimp and crab. Background technique [0002] Shrimp and crab are widely welcomed by people because of their delicious meat. In recent years, shrimp and crab have become an important economic breeding species in China. The market price is getting higher and higher, and the demand is increasing, thus driving the development of artificial breeding. [0003] At present, there are still some deficiencies in the existing rice shrimp and crab breeding, for example; the existing rice shrimp and crab breeding does not organically combine shrimp and crab farming with rice planting, so that the two are mutually beneficial and symbiotic and give full play to the advantages of farmland. Productivity slows down the growth rate of shrimp and crabs, and the survival rate of shrimp and crabs is relatively average, which r...
