Culture solution for dendrobium officinale

Abstract

The invention discloses a culture solution for dendrobium officinale, and belongs to the technical field of agricultural planting. The culture solution is prepared from the following raw materials inparts by weight: 0.5-0.54 part of manganese sulfate, 0.11-1.3 parts of potassium iodide, 1.1-1.15 parts of sodium bicarbonate, 0.05-0.4 part of zinc sulfate, 1.2-1.33 parts of anhydrous sodium dihydrogen phosphate, 2.5-3.3 parts of a composite mineral substance, 2.7-4.6 parts of glucose, and 5-10 parts of water. The culture solution for the dendrobium officinale provided by the invention has reasonable compatibility, can rapidly promote root growth and produce stems, can improve the contents of polysaccharide and amino acid in the dendrobium officinale, and significantly improve the survival rate of transplanting of the dendrobium officinale.

Description

technical field [0001] The invention relates to a culture solution of Dendrobium officinale, belonging to the technical field of agricultural planting. Background technique [0002] Dendrobium officinale: stems erect, cylindrical, 9-35 cm long, 2-4 mm thick, unbranched, multi-noded; leaves two rows, papery, oblong-lanceolate, margins and middle ribs often lavender . Racemes often emanate from the upper part of old stems that have fallen leaves, with 2-3 flowers; bracts dry membranous, light white, ovate, 5-7 mm long, sepals and petals yellow-green, nearly similar, oblong lanceolate, lip white, with a green or yellow callus at the base, ovate-lanceolate, slightly shorter than sepals, reflexed in the middle. Stamens yellow-green, about 3mm long, with 1 purple spot on both sides of apex; medicine cap white, long ovate-triangular, about 2.3mm long, apex subacute and 2-lobed. The flowering period is from March to June. Born on semi-shady rocks in mountains up to 1600 meters a...

Problems solved by technology

[0003] 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.
