Method for cultivating and planting organic dendrobium candidum

Abstract

The invention discloses a method for cultivating and planting organic dendrobium candidum. Illumination is conducted on dendrobium candidum tissue culture seedlings through LED red and blue hybrid light, and control and adjustment are conducted on factors such as an illumination period and a light intensity environment of the tissue culture seedlings at different stages, so that the speed of expanding propagation of the tissue culture seedlings is fast, and the yield is high; the cultivation time of the dendrobium candidum from seeds to finished rooting seedlings is about 160 days, high quality seedlings account for over 90% of total amount of the seedlings, the time for seedling hardening is about two weeks, the survival rate of seedbed planting in a greenhouse can reach over 98%, the time for seedling hardening for the tissue culture seedlings is short, the survival rate of transplanting is high, plant diseases and insect pests are few, the acidic water quality is adopted, fertilizer is not needed, and the growing environment of the dendrobium candidum is closer to the natural environment, so that the quality of the dendrobium candidum is guaranteed, nutritional ingredients of the dendrobium candidum is close to those of wild dendrobium candidum, and the medicinal value is high.

Description

technical field [0001] The invention relates to a method for cultivating and planting organic dendrobium officinale. Background technique [0002] Dendrobium candidum is one of the most precious species in the Orchidaceae Dendrobium in my country. Because of its effects of enhancing the body's immunity, anti-tumor, anti-aging and effectively reducing liver damage, it was listed as a single blind medicinal material in the 2010 edition of "The Pharmacopoeia of the People's Republic of China". Its own reproductive rate is low, and the resources of wild Dendrobium officinale are gradually depleting. It has been listed as a rare and endangered plant under the second-level key protection by the state. Now, the artificial cultivation of Dendrobium officinale has become the main way to meet the huge market demand. Dendrobium officinale is a plant of the genus Dendrobium in the family Orchidaceae. The seeds are extremely small and have no endosperm. Under natural conditions, they n...

[0006] But, prior art is in large-scale production, when the cultivation time of Dendrobium candidum seedling from seed to rooted finished product seedling is 150 days, qualified seedling only accounts for about 50% of total seedling amount; about 80% of the amount; and it takes a long time for seedling hardening to have a transplant survival rate of more than 90%
