The Dendrobium officinale Kimura et Migo has a high demand on planting matrix, while its tissue culture seeding has much more demands on planting matrix. To find out a seeding exercise matrix to enhance the survival rate of tissue culture seeding of Dendrobium officinale Kimura et Migo more efficiently, this article carries out a screening test of greenhouse seeding exercise matrix material for tissue culture seeding of Dendrobium officinale Kimura et Migo. The test adopts full random test design, mainly for screening test of five matrix materials, namely pine bark, camphor tree bark, fern root, peanut shell and longan bark. Compare the impact of prepared seeding exercise matrix on the survival rate and growth trend (including plant height, growth rate and bud growth rate). The test result shows that: The seeding exercise matrix prepared by fern root is the most efficient, and the survival rate, plant height, growth rate and bud growth rate have achieved 100%, 4.5cm, 43.67% and 54.33% respectively. The main reason may be that the seeding exercise matrix C prepared by fern root is fairly loose and has a great water permeability, which is conducive to the growth of Dendrobium officinale Kimura et Migo.
Key words: Dendrobium officinale Kimura et Migo / tissue culture seeding / seeding exercise matrix / screening test
