Three-dimensional planting and breeding method for rice, fish and ducks

Abstract

The invention discloses a three-dimensional planting and breeding method for rice, fishes and ducks. According to the three-dimensional planting and breeding method for the rice, the fishes and the ducks, a fishpond is arranged on the downstream of a water inlet, a duck shed is arranged on a water outlet, aquatic plants are planted in ditches, the situation that the ducks pollute breeding water when moving in the rice field is avoided, the duck releasing time and the duck collecting time are controlled, the activity space of the fishes and the ducks is separated, and friendly symbiosis of the fishes and the ducks is achieved, unbalance of an ecological system is avoided; sagittaria sagittifolia is planted in the ditch to provide a place for daytime activities of the fishes and can also be used as feed of the fishes, the sagittaria sagittifolia is planted on the side, close to the rice field, of the annular ditch to prevent duck manure and the ducks in the rice field from entering the breeding water, and hornwort is planted at the bottom of the ditch to provide food for the fishes, purify the water and keep good water quality conditions, the water body enrichment phenomenon is avoided.

Description

technical field [0001] The invention relates to the technical field of ecological planting and breeding, in particular to a method for three-dimensional planting and breeding of rice, fish and ducks. Background technique [0002] The rice-fish-duck symbiosis system is a long-term developing agricultural ecosystem in southern China. This system does not use chemical pesticides in the process of planting and breeding, which has a significant protective effect on the surrounding ecological environment and makes full use of land resources. The traditional agricultural model that experts are determined to preserve is of great significance to the production of healthy and safe green food. [0003] Chinese patent CN109526810A "A Method for Co-cultivation of Rice, Fish and Duck" includes seven steps of field improvement, water disinfection, rice cultivation, fish and duck stocking, field management, harvesting and straw returning to the field, through fine management of time, space ...

AI Technical Summary

Problems solved by technology

[0005] However, the current rice-fish-duck symbiosis system still has the following problems: First, water pollution. Although the weeds and insects that grow in the rice fields provide ducks with natural animal and plant feed, in order to ensure that ducks have sufficient nutrition, they still need to be supplemented. Feeding supplementary feed, the area of ​​the paddy field is large, and feeding supplementary feed will easily cause water pollution; the second is high-density farming, the organic matter in the water consumes a lot of nutrients, the amount of dissolved oxygen is small, the decomposition of anaerobic bacteria increases, and the ammonia nitrogen content in the water The proportion of nutrient salts in the water is unbalanced, which leads to the deterioration of water quality. The large-scale use of drugs and water quality improvers not only increases the cost, but also affects the quality of aquaculture products. Moreover, high-density farming tends to produce too much duck manure and fish, resulting in The eutrophication of the water body will cause fish to die easily due to lack of oxygen, and will also cause harmful microorganisms and germs to multiply in the water; third, the unreasonable proportion of fish and ducks will cause the imbalance of the ecosystem, and will also lead to the deterioration of the water quality, indirectly causing Various diseases of fish and ducks
