Abstract

The invention relates to an azolla wet-culture oxygen supply device, comprising a base and a cultivating bedstead arranged on the base. The device is characterized in that the cultivating bedstead is internally provided with multiple layers of azolla moistening cultivation disks, light sources are arranged on each layer of cultivation disk, one side of the cultivation disk is provided with a culture solution water inlet branch pipe connected with a culture solution storage tank through a water inlet manifold, the other side of the cultivation disk is connected with a water return manifold communicated with the culture solution storage tank for forming a circular culture solution supplying loop. The device has simple structure, convenient operation and reasonable structure function, and can effectively ensure the wet-culture cultivation of the azolla and the conduction of oxygen supply experiments.

Description

technical field [0001] The invention relates to a cultivating device, in particular to an oxygen supply device for wet cultivation of red duckweed. Background technique [0002] Hongping, scientific name Manjianghong ( Azolla ), is an aquatic fern, usually more aquatic. Hongping has a high growth and reproduction rate, and photosynthesis releases O 2 Strong capacity, high edible biomass yield and rich nutrients (rich in protein, mineral elements and essential amino acids for humans), especially Hongping is suitable as a salad vegetable, can be multi-layered and moist, green per unit space With a large area, it is expected to be used as a biological component of a space-controlled ecological life support system (CELSS) to provide O 2 and fresh vegetables, which absorb CO 2 role. Therefore, Hongping can be used as an oxygen provider for space manned oxygen supply. In order to study the feasibility of the oxygen supply and wet culture of Hongping, and provide test equipme...
