Artificial light cultivating method of dendrobium candidum

Abstract

The invention discloses an artificial light cultivating method of dendrobium candidum. The method comprises the following steps: naturalized young plants are transplanted to a nutrition pot or a potted tray containing base material and placed in a three-dimensional cultivating shelf of an artificial light closed plant factory; wherein cultivating conditions are as follows: the illumination intensity is 60-150 mu mol.m-2.s-1; the illumination time is 9-12h.d-1, the temperature is 24-27 DEG C; the relative humidity is 65-80%; the CO2 concentration is 400-800 mu mol.m-1; and the air velocity is 0.3-0.6 m.s-1; after the young plants are transplanted, atomizing keeps the humidifying state of leaf surfaces of the young plants before 2 weeks; after two weeks, the young plants are watered; according to the principle of keeping the humidification of the base material, macroelement nutrient solution is applied every 7 to 15 days; microelement nutrient solution is applied every 25 to 35 days; bottom surface is watered every 3 to 5 days; the young plants are harvested after being cultivated for 1.5 to 2 years and every half year is a picking time. The method shortens the production period, guarantees the uniform quality of the products, and increases the yield.

Description

technical field [0001] The invention belongs to the technical field of medicinal plant cultivation, and in particular relates to an artificial light cultivation method of dendrobium officinale. Background technique [0002] Dendrobium officinale Kimura et Migo is a traditional precious Chinese medicinal material, which ranks first among the nine immortal grasses in China.

Problems solved by technology

At present, the market demand of Dendrobium officinale at home and abroad is at least nearly one million tons, but the market supply is less than 1%. Goods, become a veritable "plant gold"

However, it takes 3-4 years for this cultivation mode to enter the harvest period, and because the greenhouses / greenhouses and other facilities for Dendrobium officinale cultivation in various places control the plant growth environment extensively, it is difficult to control the quality of the medicinal herbs. The production cycle and unstable herbal quality seriously restrict the production scale and market supply of Dendrobium officinale
