Embodiment Construction

[0082] In the following examples, the raw materials for preparing the nutrient solution were purchased from Beijing Lanyi Chemical Products Co., Ltd. Dendrobium officinale seedlings are from Zhejiang Fenghe Biotechnology Co., Ltd.

[0083] 1. Composition of nutrient solution

[0084] The nutrient solution takes N, P, K, Ca, and Mg as the main proportion of a large number of elements to carry out the following mass ratio:

[0085] N3 area: N: P: K: Ca: Mg = 3: 1: 1: 1.5: 1

[0086] N5 area: N: P: K: Ca: Mg = 5: 1: 1: 2.5: 1

[0087] K2 area: N: P: K: Ca: Mg = 3: 2: 2: 1.5: 1

[0088] K4 area: N: P: K: Ca: Mg = 5: 4: 4: 2.5: 1

[0089] CK zone: N: P: K: Ca: Mg = 5: 1: 1: 2.5: 1

[0090] Other trace elements are configured with Fe:B:Mn:Zn:Cu:Mo=2:0.2:0.2:0.02:0.01:0.005 mass ratio.

[0091] The composition of the specific nutrient solution is shown in Table 1.

Abstract

The invention discloses a cultivation method of dendrobium officinale and a special nutrient solution thereof. The nutrient solution is composed of solutes and a solvent. The solvent is water, and the solutes include an N source, a P source, a K source, a Ca source, a Mg source, a Fe source, a B source, an Mn source, a Zn source, a Cu source and a Mo source, wherein the mass ratio of N element, P element, K element, Ca element and Mg element in the N source, the P source, the K source, the Ca source, the Mg source is (3-5): (1-4): (1-4): (1.5-2.5): 1. According to the cultivation method of the dendrobium officinale, solid culture can be performed under suitable artificial light or natural light, growth and development of the dendrobium officinale can be promoted, production cycle can be shortened, and yield and quality of the dendrobium officinale can be improved finally. Therefore, the cultivation method of the dendrobium officinale and the special nutrient solution thereof have broad application prospects.

Description

technical field [0001] The invention relates to a method for cultivating dendrobium officinale and a special nutrient solution thereof. Background technique [0002] Dendrobium officinale Kimura et Migo is a traditional precious Chinese herbal medicine, ranking first among the nine immortal grasses in China. It has the effects of nourishing yin and clearing heat, promoting body fluid and benefiting stomach, moistening lung and relieving cough, nourishing five internal organs and consumptive fatigue, etc., and has obvious effects in improving human immunity, anti-aging, inhibiting tumors, improving symptoms of diabetes and atrophic gastritis. [0003] Due to the deteriorating ecological environment and the predatory excavation of medicinal farmers, the wild resources of Dendrobium officinale are on the verge of exhaustion. In 1987, it was listed as a key second-level protected wild rare medicinal species by the state. At present, the market demand of Dendrobium officinale at...
