Rice field-fishpond planting and breeding compound system

Abstract

The invention relates to a rice field-fishpond planting and breeding compound system, which belongs to the technical field of comprehensive utilization of agricultural ecological aquaculture. The compound system comprises a rice field, a fishpond, a simple ecological ditch and a strengthened ecological ditch, wherein the rice field is arranged at one end of the fishpond; the strengthened ecological ditch and a water collecting tank are respectively arranged on one side of each of the fishpond and the rice field; the simple ecological ditch is formed in the rice field; a small overflow port is formed in the simple ecological ditch; the rice field is communicated with the water collecting tank by a large overflow port; the fishpond is communicated with the simple ecological ditch by a water suction pump. According to the rice field-fishpond planting and breeding compound system disclosed by the invention, the rice field planting and the fishpond breeding are organically combined by the ecological ditches, so that the fishpond breeding water is refluxed to a new circulating water planting-breeding mode after being purified by the rice field and the ecological ditch. Moreover, the problems that an existing rice-orientated planting-breeding mode with the fish breeding has rice-fish contradictions including field drying, fertilizer applying, pest controlling and the like in the production process, and is limited in yield and inconvenient for large-area popularization are solved.

Description

technical field [0001] The invention relates to a paddy field and fish pond planting and breeding complex system, which belongs to the technical field of comprehensive utilization of agricultural ecological aquaculture. Background technique [0002] Traditional paddy-fish farming is a rice-fish production method in which fish ditches and fish slides are excavated in paddy fields for fish farming. Its remarkable advantage is that fish can be raised on the water surface of rice fields, which can not only obtain fish products, but also use fish to eat pests and weeds in rice fields, excrete manure, turn soil to promote fertilizer decomposition, and create good conditions for rice growth. Increase production by about 10%. This rice-based farming model also takes fish farming into account. In the actual production process, there are contradictions between rice and fish such as shallow irrigation, drying the field, fertilizing, and pest control. At the same time, the production o...
