Rice and shrimp co-culture planting-breeding method

Abstract

The invention relates to a rice and shrimp co-culture planting-breeding method. The rice and shrimp co-culture planting-breeding method comprises the following steps: 1) rice field transformation; 2)water body disinfection; 3) young shrimp stocking; 4) Bacillus subtilis pouring; 5) rice cultivation; 6) rice and shrimp management; and 7) rice and shrimp harvesting. According to the invention, through pouring of the Bacillus subtilis into a water body in an annular gully, the Bacillus subtilis has strong inhibition effect on harmful microorganisms like vibrios, colibacillus and baculovirus in aquatic products, so the occurrence of diseases and pests of shrimps can be effectively prevented; the Bacillus subtilis also can consume harmful substances like ammonia nitrogen and nitrogen nitrite in a water body, so the water body is purified, and the dissolved oxygen content of the water body is improved; and by utilization of a water-flooding method, pesticide-free prevention and treatment ofdiseases and pests of rice are realized, so no influence on growth and development of the shrimps is caused, and the yield and quality of the rice and the shrimps are improved. The method provided bythe invention realizes zero use of a chemical fertilizer and a pesticide; and an agricultural product produced by using the method provided by the invention is healthy, reliable, ecological and environmentally-friendly.

Description

technical field [0001] The invention relates to an agricultural crop and an aquaculture method, in particular to a method for growing rice and shrimp together. Background technique [0002] The rice and shrimp breeding system is to transform the rice field through engineering, and to raise a certain number of shrimp in the rice field reasonably, so as to realize "planting rice on the surface of the field, raising shrimp in the water body, shrimp manure field, and rice and shrimp symbiosis". On the one hand, the rice and shrimp breeding system uses shrimps to feed on rice field Cordyceps, turning it into organic fertilizer, reducing the use of pesticides and fertilizers; building ecological ditches in rice fields, storing rainfall, reducing farmland emissions, controlling resource pollution, and regulating field water and fertilizer heat, and promote high-quality and high-yield rice. On the other hand, the rich food source and good ecological environment of the paddy fields ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a feasible solution to the problems existing in the existing rice and shrimp breeding system, by putting Bacillus subtilis in the water body of the ring ditch, consuming harmful substances such as ammonia nitrogen and nitrite nitrogen in the water body, purifying Water body, increase dissolved oxygen in water body
