Fish, vegetable and flower symbiosis device and method

Abstract

The invention provides a fish, vegetable and flower symbiosis device and method, and relates to the technical field of fish, vegetable and flower symbiosis. The fish, vegetable and flower symbiosis device comprises a hydroponic barrel, wherein a water inlet pipe is vertically inserted and arranged into the inner side edge of the hydroponic barrel; a first water inlet hole and at least one second water inlet hole are formed in the water inlet pipe in the vertical direction; the first water inlet hole is positioned above the second water inlet hole; the opening directions of the first water inlet hole and the second water inlet hole are consistent; the first water inlet hole controls the water level in the hydroponic barrel; a siphon mechanism for discharging metabolites in water is arrangedin the center of the hydroponic barrel; the top of the siphon mechanism is as high as the first water inlet hole; a round ecological floating plate floats on the water surface in the hydroponic barrel; a floating plate center round hole is formed in the center of the round ecological floating plate; and the floating plate center round hole is positioned right above the siphon mechanism. The fish,vegetable and flower symbiosis device is mainly used for the field of fish, vegetable and flower symbiotic cultivation; nonuniform light receiving of plants can be avoided; and the yield of cultivated plants is effectively stabilized.

Description

technical field [0001] The invention relates to the technical field of fish cauliflower symbiosis, in particular to a fish cauliflower symbiosis device and method. 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 large-scale fish-vegetable production workshops and promoting the pond fish-vegetable farming model, the design and development of independent miniature fami...

Problems solved by technology

[0004] However, family aquaponics system products are affected by factors such as large initial investment and high operating costs, which limit their promotion and use

In addition, in the existing symbiosis system, the phenomenon of uneven biomass growth of hydroponic plants occurs in most of the plants planted, and the plant growth often appears "one-sided" phenomenon, which affects the yield and ornamental effect of the fish cauliflower symbiosis system
