Eco-organic breeding method with co-culture of rice and crawfishes

Abstract

The invention discloses an eco-organic breeding method with co-culture of rice and crawfishes. The method comprises the following steps: construction of a standardized breeding field, artificial breeding of earthworm baits, preparation prior to delivery of shrimp seeds, delivery of shrimp seeds, management of a culture stage, cultivation of rice and catching the crawfishes. Without changing the construction standard of the breeding field, rice varieties and shrimp varieties, chemical fertilizers are not utilized for planting rice. Nutrients come from waste reutilization during cultivation of live baits. Fermented feces and forage mixtures are utilized for cultivation of earthworms. The earthworms are utilized for breeding the crawfishes. Therefore, green and organic production of rice and crawfishes is achieved so that economic benefit and social benefit are improved.

Description

technical field [0001] The invention relates to the fields of crops and aquaculture, in particular to a method for ecologically organic farming of rice and shrimp. Background technique [0002] In crop production, rice is the most constrained crop by water and soil resources. At present, the development of the rice industry is facing severe situations such as steady growth in consumption, increased resource constraints, disastrous climate, frequent occurrence of diseases and insect pests, and low comparative benefits. In order to stabilize and increase production, chemical fertilizers and pesticides are widely used in traditional rice production. This not only brings hidden dangers to food safety, but also causes long-term accumulation of toxic substances such as organic matter and heavy metals, which can also cause soil compaction, deterioration of soil physical and chemical properties, and damage to the ecological environment. [0003] Crayfish, also known as Procambarus c...

Problems solved by technology

However, due to serious water pollution, the quality of wild crayfish has been seriously affected. In order to increase production, artificial breeding usually adds various mixed feeds, which is not conducive to improving product quality and food safety cannot be guaranteed.
