Problems solved by technology

Scholars at home and abroad have conducted many studies on the decomposing of Dendrobium officinale, but mainly focused on tissue culture and rapid propagation, cultivation methods, identification of medicinal materials, and analysis of chemical components. less research
[0004] Dendrobium candidum is widely planted in Yunnan, Guangxi, Zhejiang, Anhui and other places. Many scholars at home and abroad have done a lot of research on the cultivation, reproduction and genetic diversity of Dendrobium candidum in Zhejiang, Guangzhou and other places. However, for high latitude areas (such as Weifang, Shandong Province) is less researched, in order to promote the widespread planting of Dendrobium candidum in high latitude areas and improve the quality of Dendrobium candidum in high latitude areas, it is necessary to propose a cultivation method suitable for high latitude Dendrobium candidum

Embodiment 1

[0024] A cultivation method suitable for high-latitude dendrobium officinale comprises the steps:

[0025] Step 1, material selection: select the seedlings of Dendrobium candidum grown in the wild, and carry out explant culture, cultivate flower buds or leaf buds, and carry out the propagation and cultivation of sterile lines with flower buds or leaf buds;

[0026] Step 2, base selection: the cultivation site of Dendrobium officinale is selected at 36°78' north latitude, and a solar greenhouse is built, a grid frame is erected, and a black sunshade net is covered with a shading rate of 70%;

[0027] Step 3. Substrate production: use pine bark and pine cone particles as the substrate material, and crush the pine bark and pine cone particles into corn grain-sized granules or fine blocks, soak in water for 7 days, dry them, steam sterilize, and maintain at 90°C more than one hour;

[0028] Step 4: Planting and cultivation: Transplant in May, fill the substrate evenly into the 32...

Abstract

The invention discloses a cultivation method suitable for high latitude dendrobium officinale. The method comprises the steps of material selection, base field selection, base material fabrication, field planting and cultivation, spraying and watering, weeding and topdressing and pest control. The cultivation method is simple and reasonable in step, the cultivated dendrobium officinale is high in survival rate, the open shed type management is adopted, ventilation and air permeability of a cultivation environment are guaranteed, natural factors of a high latitude region such as sufficient sunlight and appropriate temperature and humidity are utilized, the dendrobium officinale is cultivated in the high latitude region in China, compared with the prior art, the content of polysaccharides, the content of chlorophyll a, the content of chlorophyll b, the content of the element Cu and content of the element Zn in the cultivated dendrobium officinale are all increased obviously, the dendrobium officinale quality is improved, high medicinal value and high edible value of the dendrobium officinale are guaranteed, meanwhile, dendrobium officinale plantation in the high latitude region of China is promoted, and economic development is boosted.

Description

technical field [0001] The invention relates to the technical field of dendrobium candidum cultivation, in particular to a cultivation method suitable for high-latitude dendrobium candidum. Background technique [0002] Dendrobium officinale is a perennial epiphytic herb of Orchidaceae. It is sweet in taste and slightly cold in nature. Medicinal materials are mainly distributed in Anhui, Zhejiang, Fujian and other places in China. [0003] The polysaccharide content and nutrient element content of Dendrobium candidum are important quality traits of Dendrobium candidum. In order to survive, plants adapt to changes in the surrounding environment by changing their intrinsic or extrinsic characteristics in different ways. Therefore, different ecological factors, especially latitude, temperature, humidity, etc., will have a certain impact on the quality and physiological indicators of plants. Scholars at home and abroad have conducted many studies on the decomposing of Dendrob...
