Abstract

The invention discloses a duckweed stereoscopic culturing apparatus mainly comprising duckweed culturing box bodies and a stereoscopic culturing rack. The duckweed culturing box bodies are placed on the stereoscopic culturing rack. Compared with a common culturing apparatus, culturing efficiency can be improved by more than two times by the use of the stereoscopic culturing apparatus; besides, the duckweed stereoscopic culturing apparatus is simply structured; and due to great stereoscopic expansion space and high spatial utilization rate, duckweeds can be cultured on a large scale, so whole output of the duckweed can be improved.

Description

technical field [0001] The invention relates to the field of biology, in particular to a three-dimensional culture device for duckweed. Background technique [0002] Duckweed is the general name of Lemnaceae plants. It is the smallest flowering plant in the world. It has 5 genera and 37 species. It grows fast and can reproduce one generation in 16 hours under ideal conditions. Its biological The yield of duckweed is 28 times that of corn; the content of duckweed starch is high, and the starch content of some duckweed varieties can reach 75% under certain conditions. Duckweed starch is easily converted into ethanol. 6.42?103 liters / ha, its ethanol yield is 50% higher than that of corn; in addition, the content of duckweed cellulose (~10%) and lignin (~2%) is low, and its pretreatment in the process of bioethanol production is more Simple. Based on the above points, duckweed is considered to be one of the most promising strategic raw materials for future biomass liquid fuels...
