Abstract

The invention discloses the technical field of crops and aquaculture, and provides a rice and crayfish co-cropping planting and breeding method. The rice and crayfish co-cropping planting and breeding method comprises the five steps of rice field transformation, water body treatment, rice planting, breeding management and rice and crayfish harvesting. In the planting and breeding process, water in a circular ditch is changed every five days, it is guaranteed that water flow in the circular ditch is fresh and sufficient in oxygen, the flowability of the water flow in the circular ditch is guaranteed, and the situation of smelly water is avoided; on the third day after water changing, disinfectant chlorine dioxide composed of chlorine dioxide, calcium peroxide and Chinese herbal medicine insecticidal water is spread into the circular ditch to effectively sterilize the water in the circular ditch, the calcium peroxide slowly releases oxygen when being spread into the water, so that the oxygen content of the water flow in the circular ditch is effectively increased, growth of crayfishes is facilitated, and the frequency of changing the water flow in the circular ditch is reduced.

Description

technical field [0001] The invention relates to the technical field of crops and aquaculture, in particular to a rice and shrimp co-cultivation method. Background technique [0002] Ecological planting and breeding is an inevitable trend in the development of agricultural industrialization. Its characteristics are based on the principle of symbiosis and complementarity between planting and breeding animals and plants, using the material circulation system in nature, and through corresponding planting and breeding techniques and management measures, animals and plants can be cultivated in a certain way. Space and area grow together to achieve the purpose of maintaining ecological balance and improving breeding efficiency. [0003] Crayfish are delicious and nutritious, and are deeply loved by people. They are currently the main species of shrimp breeding. In recent years, due to the sharp increase in market demand, the natural resources of crayfish have decreased sharply, an...
