Example Embodiment

[0020] On the land of the ecological breeding farm area, the traffic road is first built in a cross shape to facilitate the transportation in the later stage, and several breeding units are built on both sides of the traffic road. Various breeding units are composed of paddy fields and back-shaped ditches (shrimp ponds). Around the paddy fields, back-shaped ditches are dug and built. The back-shaped ditches account for 8% of the total area of ​​the farming units. The bottom width is 1.5 meters, the depth is 1.8 meters, and the slope ratio is 1:1.5; a 3-meter-wide isolation zone (field ridge) is maintained between various breeding units to prevent them from being dug through during the breeding process. The traffic road is a cement road, and the field ridge is a mud-concrete road. After the winding ditch is excavated, quicklime is used for disinfection, and yellow silk grass and Elodea aquatic plants are planted in the winding ditch. At the same time, weeds must be removed. Mix...

Abstract

The invention relates to an ecological breeding method for rice-shrimp co-culture and belongs to the technical field of crops and aquaculture. The ecological breeding method achieves rice-shrimp co-culture through construction, shrimp putting, adult shrimp catching and rice planting in a co-culture ecological farm zone, does not change the usage properties of land, does not adopt drugs, does not destroy the usage situation of the land, does not pollute a water body or discharge gas and substances, and thus has no adverse effect on the natural environment. In addition, the land utilization rate is improved and a very important demonstration effect is also played on virtuous ecological circle through co-culture. The method needs perfection of a national food security guarantee system and establishment of an agricultural sustainable development long-term mechanism and has the positive significance on deepening of rural land institution reform, establishment of a novel agriculture management system and guarantee of food security.

Description

technical field [0001] The invention relates to a rice and shrimp co-cropping ecological breeding method, which belongs to the technical field of crops and aquaculture. 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. Since 2005, crayfish has been popular all over the country with its unique food culture and consumption patterns. It has stepped onto the big stage of urban economy from the field and has become an important aquaculture species in my country's freshwater aquaculture. The rapid development is unstoppable. [0003] 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 gre...
