Problems solved by technology

[0003] The existing co-culture of shrimp and rice has a relatively simple breeding method, which is purely a combination of the two and does not solve various problems in the breeding process. Therefore, the breeding efficiency is greatly limited

Embodiment 1

[0016] Paddy field finishing: select the paddy field where crayfish are raised, and excavate a "one" type shrimp ditch along the outer edge of the field ridge. The ditch is 1 meter deep, 4 meters wide, and the slope ratio is 1:1.5. The field ridge is 0.6-0.8 meters higher than the field surface. The top is 2-3 meters wide, and evacuation nets are set up on the ridge; the shrimp ditch and rice field are freeze-dried, aired and sterilized, and water is poured into the breeding field with a water surface height of 6-8cm; according to the amount of 30% of the water surface area of ​​the rice and shrimp breeding ditch, 10-15 days before the shrimp species are put in, in the said shrimp breeding ditch, transplant scallops, duckweed and spirulina, wherein scallops account for 30% of the total number of aquatic plants, duckweeds account for 40%, and spirulina accounts for 30%. %;

Abstract

The invention discloses a rice and cray synergetic ecological breeding method. Soil is loosened and insect pests are removed for rice by breeding crays. According to the characteristic of rice absorbing nutritional elements in a water body and a shading action, the breeding water body is purified, habituating and concealing places are also provided for the crays, a good growth environment is created for the crays, and the quality of the cray breeding product is improved. The metabolic products of the crays and feces of the crays increase organic fertilizers for production of rice in the comingyear, so that rich organic fertilizers can be provided for growth of rice. Dosages of chemical fertilizers and pesticides are reduced in the rice planting process to promote growth. Meanwhile, the space of the rice paddy is utilized effectively. In the water quality keeping aspect, organic components in soil and feeds are decomposed to ammonia, so that the ammonia and nitrogen content in the water body is increased. The water quality is easy to eutrophicate. The crays bred are quick to grow and order in specification, and normal production of rice is not affected, and one rice paddy is dual-purpose, so that the income is increased greatly.

Description

technical field [0001] The invention relates to the field of rice and aquaculture comprehensive cultivation, in particular to a method for ecological cultivation of rice and shrimp. Background technique [0002] Crayfish, also known as Procambarus clarkii, is native to North America and was brought into my country from Japan in the 1930s, where it has been in a spontaneous wild state for a long time. Crayfish has swept the country with its unique food culture and consumption patterns. It has grown from the field to the big stage of the urban economy and has become an important aquaculture species in my country's freshwater aquaculture. Its rapid development is unstoppable. Agriculture is the foundation of national economic development. In recent years, with the development of science and technology and policy innovation, my country's agricultural economic benefits have continued to increase. However, the excessive pursuit of economic benefits has greatly increased the amoun...
