Culture medium for dendrobium officinale tissue culture seedling

Abstract

The invention belongs to the technical field of plant cultivation, and provides a culture medium for a dendrobium officinale tissue culture seedling. The culture medium is prepared from, by weight, 200-300 parts of apple butter, 300-400 parts of mashed banana, 150-350 parts of white sugar, 80-105 parts of ferrous sulfate, 20-35 parts of ammonium nitrate, 30-40 parts of nitrate of potash, 5-10 parts of magnesium sulfate, 3-5 parts of monopotassium phosphate, 3-5 parts of boric acid, 5-7 parts of glycine, 1-3 parts of vitamin B1, 1-3 parts of vitamin B2, 15-20 parts of sugar amino acids, 15-20 parts of naphthylacetic acid, 100-200 parts of milk, 3.5-7 parts of brown sugar, 5.5-11 parts of eggs, 50-100 parts of lactic acid bacteria, and 1000-1500 parts of tap water. The culture medium is reasonable in collocation and comprehensive in nutrition, can quickly promote rooting and stem generation, improves contents of polysaccharide and amino acid in the dendrobium officinale, shortens the culture cycle of the dendrobium officinale, improves the survival rate of transplanting of the dendrobium officinale, and reduces cost of production.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a culture medium for dendrobium candidum tissue culture seedlings.

Problems solved by technology

[0005] At present, in the propagation system of Dendrobium candidum test-tube seedlings, the rooting medium adopts solid medium. The application of solid medium not only increases the production cost, but also easily causes root damage when taking seedlings, and reduces the survival rate of transplanting.
