Abstract

The invention relate to a dendrobium officinale planting method. The method comprises the following steps of greenhouse building, culture substrate preparation, transplanting, watering, fertilization, pest and disease damage control, temperature and humidity control and harvesting. By means of the planting method, dendrobium officinale is not likely to get ill or be gnawed by pests, the polysaccharide content of the dendrobium officinale can reach 30% or above, and the content of predominant amino acid and microelements of zinc, copper, magnesium, potassium, calcium, iron, manganese and the like are higher than that of wild dendrodium. By adopting the method for planting, the survival rate of the dendrobium officinale can reach 96% or above, the incidence rate of the pest and disease damage is obviously deceased, harvesting within 18 months can be achieved, the content of various nutrient components of the dendrobium is high, and the medicinal effect can achieve the effect of the wild dendrodium.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to a planting method of dendrobium officinale. Background technique [0002] Dendrobium officinale, also known as black knot grass, is the stem of Dendrobium officinale Kimura et Migo, a perennial epiphytic herb of the genus Dendrobium orchidaceae. It is named for its iron-green skin and is a precious wild medicinal plant. Born on the semi-shady rocks in the mountains at an altitude of 1600 meters, it likes warm and humid climates and semi-shady and semi-yang environments, and is not cold-resistant. Generally, they can withstand low temperatures of ~5°C. Dendrobium can be divided into dozens of species such as yellow grass, nobile, horsewhip, etc. Dendrobium candidum is the best product of Dendrobium. Dendrobium candidum has unique medicinal value. Its stems are used as medicine. According to the "Chinese Pharmacopoeia", Dendrobium has the effects of nourishing ...
