Fish, vegetable and flower symbiotic cultivation device and method

Abstract

The invention provides a fish, vegetable and flower symbiotic cultivation device and method, and relates to the technical field of fish, vegetable and flower cultivation. The device comprises a support frame, wherein a water culture barrel is arranged at the top of the support frame; a water inlet pipe is vertically inserted into the inner side of the water culture barrel, at least two water inletholes are formed in the water inlet pipe in the vertical direction, the opening directions of the water inlet holes are consistent, and the highest water inlet hole controls the water level in the water culture barrel; a siphon mechanism for removing metabolites in water is arranged in the center of the water culture barrel; the top of the siphon mechanism is as high as the highest water inlet hole; a circular ecological floating plate floats on the water surface of the water culture barrel; a floating plate central circular hole is formed in the center of the circular ecological floating plate; and the floating plate central circular hole is positioned right above the siphon mechanism. The fish, vegetable and flower symbiotic cultivation device and method are mainly used for fish, vegetable and flower symbiotic cultivation, can avoid uneven light receiving of plants, achieves closed-loop circulation, are high in space utilization rate and are suitable for scientific research, production, exhibition, households and other environments in northern areas.

Description

technical field [0001] The invention relates to the technical field of fish cauliflower cultivation, in particular to a device and method for symbiotic cultivation of fish cauliflower. Background technique [0002] As early as 1,000 years ago, there was a history of fish farming in rice fields in the Jiangsu and Zhejiang areas of our country. In 1997, Dr. James Rakocy of the University of the Virgin Islands developed a large-scale fish-vegetable symbiosis system based on deep water cultivation. The Food and Agriculture Organization of the United Nations has also promoted the small-scale fish-vegetable hydroponic system as a sustainable agricultural model to the world. my country began to promote ecological agriculture in the 1990s, and fish-vegetable hydroponic industrial farming has formed a large-scale situation. [0003] While building a large-scale production workshop and promoting the pond fish and vegetable farming model, the design and development of an independent ...

AI Technical Summary

Problems solved by technology

However, due to its high operating cost and other factors, its promotion and use are limited.

In addition, due to environmental influences, most plants are planted on square fixed floating plates, and holes are drilled according to certain specifications, resulting in uneven light reception, and the growth of plants often appears "one-sided" phenomenon, which affects the output of fish and cauliflower symbiosis systems, etc.
