Mountainous area field rice-fish symbiotic breeding method and field structure

Abstract

The invention discloses a mountainous area field rice-fish symbiotic breeding method and a field structure. The field structure comprises an outer ridge, a circle of inner ridge is piled up on the inner side of the outer ridge, a fish ditch is excavated between the outer ridge and the inner ridge, one or more fish inlet channels are arranged on the periphery of the inner ridge, the fish ditch and a rice planting area in the inner ridge are communicated through the fish inlet channels, and a water inlet and a water outlet are formed in the opposite angles of the fish ditch respectively. The rice-fish symbiotic breeding method is easy to operate, convenient to implement and beneficial to large-scale popularization, both fish ditch excavation and rice harvesting can be mechanically completed, and a large amount of cost can be reduced for the mountainous area. Meanwhile, the energy flow relation in rice-fish symbiotic breeding is fully utilized, that is, fishes feed on weeds, injurious insects and the like in a field, manure generated by the fishes can serve as fertilizer of the rice, fertilizer and pesticide are saved, and the weeding cost is reduced.

Description

technical field [0001] The invention relates to a rice-fish symbiotic breeding method and a field structure in a mountainous field, and belongs to the technical field of ecological aquaculture. Background technique [0002] Fish farming in rice fields has a long history in my country and is one of the main methods of freshwater fish farming in my country. Fish farming in paddy field is to use the shallow water environment of paddy field to grow fish, shrimp and other aquatic products at the same time of planting rice. It has low investment, quick effect, no pollution and good benefit, and has broad development prospects. Fish farming in rice fields is mainly rice planting, supplemented by fish farming and aquatic products. The guiding ideology of fish farming in rice fields is to increase rice production and fish harvests. Make full use of rice fields and fish and rice together. Increased rice production is a typical green, pollution-free, low-carbon agriculture. Using the...

Problems solved by technology

[0003] Under the environmental conditions in the mountainous areas of Guizhou, the area of ​​the paddy field is small, and the height of the field is different, so it is impossible to integrate or level the paddy field. The traditional rice-fish symbiosis breeding mode is time-consuming and labor-intensive to dig fish ditches and fish ponds. It is easy to collapse in the middle, the difficulty of operation increases, the cost of breeding is high, and the promotion and management are difficult; the water in the paddy field is shallow, it is difficult for fish to survive the winter, it is difficult to dry the field, and it is not easy to harvest

These problems seriously restrict the development of this industry. Therefore, in the process of rice field farming in mountainous areas, it is urgent to solve these problems and find a new model of rice-fish symbiotic farming in mountainous areas.
