Rice and fish comprehensive planting and breeding internal circulation system and using method

Abstract

The invention discloses a rice and fish comprehensive planting and breeding internal circulation system and a using method. A ditch and an aquaculture system are arranged in a rice field, so that water circulates between the rice field and the aquaculture system, and compared with an existing rice and fish symbiosis mode, the system has the advantages that planting and breeding are relatively managed in a partitioned mode, mutual restriction is avoided, advantage complementation is achieved, aquatic products are more convenient to feed, manage and catch, mechanized harvesting of rice is also facilitated, water can be lifted to the irrigation ditch from the aquaculture system, and after the water for irrigating the rice field passes through a backflow ditch, the water is lifted to the aquaculture system from the backflow ditch through water lifting equipment to be circulated, the water forms circulation between the rice field and the aquaculture system, when the system is applied to a hilly land, the defects that the land of the hilly land is uneven, and circulating water is difficult to arrange on a large scale are overcome, and proper-scale operation of the hilly land is convenient to achieve.

Description

technical field [0001] The invention relates to the technical field of rice-fishing comprehensive planting and breeding, in particular to an internal circulation system and a method of use of rice-fishing comprehensive planting and breeding. Background technique [0002] Rice field fish farming in my country has been recorded since the Han Dynasty more than 2,000 years ago. It is mainly concentrated in southern rice planting areas such as Zhejiang. Fish are raised in rice fields, and rice and fish are symbiotic and mutually beneficial. At present, most of the existing rice-fishing farming models are symbiotic models of rice and aquatic products, that is, while rice is planted in paddy fields, aquatic products are intertwined. Feeding, management and fishing are not convenient for rice harvesting, and the efficiency of rice harvesting is low, and mechanized operations cannot be implemented, which is not conducive to popularization. Contents of the invention [0003] The pu...
