Chlorella cultivation facility and technology

Abstract

The invention provides a chlorella cultivation facility and relates to technologies related to chlorella cultivation. Chlorella cultivation is high in yield and controllable in quality by improving cultivation assisting facilities and regulating light and nutrients of a cultivation pond. The facility comprises a cultivation pond, a water supply system, a sun light control system and a fertilizer supply system. The water supply system comprises a water well, a water pump, a water valve, a water pipe and a fertilizer regulation pond. The fertilizer regulation pond comprises a fertilizer fermentation pond and a liquid fertilizer pond, and a filter screen is arranged between fermentation pond and the liquid fertilizer pond. The sun light control system comprises a sun canopy frame, a sun light dimming film and a sunshade net, the sun canopy frame is arranged on the surface of the cultivation pond which is provided with the sun light dimming film and the sunshade net, the height of the sun canopy frame is set to be 1-1.5m, and a water spraying device is arranged on a cross beam of the sun canopy and used for pond cooling.

Description

technical field [0001] The invention relates to a technique related to the cultivation of coccus algae, in particular to a facility for the cultivation of coccus algae and the cultivation technology thereof. Background technique [0002] The coccus described in the present invention refers to "薸沙", known as "Wolffia arrhiza", also known as "Wolffia arrhiza". It is a kind of algae, a monocotyledonous plant, and an aquatic plant of the family Duckweed. It is an elliptical or oval green granular body floating on the water surface, which can be seen in ponds or rice fields everywhere. It is an excellent and palatable bait for mainly breeding snails, fish, and fish species. It is also a good raw material for food processing. Wugenping is the smallest of the seed plants. It has no roots and no leaves. The fronds are nearly spherical, about 1.3-1.5mm long and less than 1mm wide. Its optimum growth temperature is at 20-30°C, and the water temperature begins to grow at 15°C, and si...

AI Technical Summary

Problems solved by technology

Existing cultivation largely adopts simple natural pool cultivation, or natural growth in rice fields, and its defect is that the growth environment is easily affected by temperature, nutrients and fertilizers, such as April-May, late October-to frost, the temperature is low and the algae grow slowly. From July to September, the temperature is high and 30 degrees, and the growth is slow, or death may occur
