Multifunctional water-surface soilless culture flotation device

Abstract

The invention discloses a multifunctional water-surface soilless culture flotation device. The multifunctional water-surface soilless culture flotation device comprises an upper-layer flotation framework, a lower-layer flotation framework, a culture layer, a plurality of positioning columns, a main path air supply pipe, a plurality of branch air supply pipes, micro-pore discs, a ceiling and a fishing net box, wherein the culture layer is fixed between the upper-layer flotation framework and the lower-layer flotation framework; the main path air supply pipe is arranged in front of the culture layer; one end of each branch air supply pipe is connected with the main path air supply pipe; the micro-pore discs are connected with the branch air supply pipes by hoses and are arranged under the bottom of the culture layer; the lower ends of the positioning columns are fixed under water and the upper ends of the positioning columns penetrate through the upper-layer flotation framework and the lower-layer flotation framework; the upper-layer flotation framework and the lower-layer flotation framework can move up and down along the positioning columns under the action of an external force; the ceiling is mounted above the upper-layer flotation framework and a feeding groove is formed in each side of the upper-layer flotation framework; the fishing net box is mounted under the lower-layer flotation framework and a plurality of circular-platform-shaped small holes for culturing plants are formed in the culture layer, so that aquaculture and agricultural production are integrated.

Description

【Technical field】 [0001] The invention relates to the technical field of soilless cultivation devices, in particular to the technical field of water surface soilless cultivation. 【Background technique】 [0002] Soilless cultivation uses peat or forest leaf humus, vermiculite and other light materials as the seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts the modern seedling technology of mechanized precision seeding for one-time seedling formation. The selected seedling tray is divided into compartments, one seed is planted in one compartment, and one plant is grown in one room. The root system of the mature seedlings and the substrate are intertwined with each other. Cultivated land, and nutrient solution can be configured according to needs, so the planting range can be expanded, crop growth can be accelerated, crop quality can be improved, resources and labor can be saved, but the configuration of nutrie...

Problems solved by technology

The selected seedling tray is divided into compartments, one seed is planted in one compartment, and one plant is grown in one room. The root system of the mature seedlings and the substrate are intertwined with each other. Cultivated land, and nutrient solution can be configured according to needs, so the planting range can be expanded, crop growth can be accelerated, crop quality can be improved, resources and labor can be saved, but the configuration of nutrient solution is difficult and costly, and the adaptability of crops to nutrient solution It takes time, and the water surface soilless cultivation floating device has overcome the above shortcomings, but the current water surface soilless cultivation floating device on the market can not protect the crops planted on it well, and the crops are easy to bend under the impact of rain and river water and the roots of the crops are prone to anaerobic respiration due to root hypoxia when submerged in water for a long time, causing the crops to die due to alcohol poisoning.
