-2s
-1between, the light application time of every day can be 1 ~ 24 hour.
Preferably, cultivate casing in ground floor duckweed and light conducting cylinder is set, can cultivate for second layer duckweed and supplementary light is provided.
Preferably, this duckweed stereo cultivation apparatus also comprises water storage box and water pump, providing duckweed culture fluid, duckweed culture fluid can be made to use in duckweed stereo cultivation apparatus inner loop for cultivating casing for three layers of duckweed.
Duckweed stereo cultivation apparatus of the present invention, cultivates the high-efficient culture achieving duckweed by the duckweeds of three layers, compared with cultivating with shallow pond duckweed conventional at present, duckweed stereo cultivation apparatus of the present invention has the following advantages and beneficial effect;
(1) the present invention makes full use of the floating water surface growth of duckweed and low light level adaptability growth characteristics, and exploitation duckweed stereoscopic culture, the more shallow pond of stereo cultivation apparatus involved in the present invention is cultivated, and culture efficiency improves more than twice.In addition, duckweed culture apparatus structure of the present invention is simple, and expands space high with space availability ratio because having higher three-dimensional, so this device to be used for the pilot scale culture of duckweed, significantly can improve the overall yield of duckweed;
(2) light source source of the present invention has two: lamp and LED light source, ground floor duckweed is cultivated and adopts lamp, the second layer utilizes scattered light and light conducting cylinder leaded light, third layer mainly relies on scattered light and LED light source, two light sources make full use of, and can realize the maximization of unit are duckweed yield of biomass;
(3) wavelength of LED light source used herein, light intensity and light application time are controlled, can adapt to the growth requirement of different duckweed, thus can reach best culture effect;
(4) the present invention is with water circulation system, can realize recycling of water.
