Problems solved by technology

In the cultivation process of Dendrobium officinale, in order to remove diseases such as germs, pests and insect eggs in the soil and the substrate, a large amount of insecticides and fungicides need to be used. This method not only increases the cost of planting, but also uses a large amount of Chemical preparations will pollute the soil and the environment. Long-term and large-scale use of chemical preparations will easily form residues in the body of Dendrobium candidum, which will affect the quality of Dendrobium candidum

Embodiment

[0044] The experiment was carried out in Yixiang Town, Simao District, Pu'er City, Yunnan Province, and the promotional cultivation area was 400 mu. Planting began in 2008, and harvesting began in 2010. It has been harvested continuously for 5 years, with an average yield of 1,200 kg of fresh Dendrobium candidum per mu. Based on the market price of fresh Dendrobium officinale of 600 yuan / kg in 2010, the output value per mu is 720,000 yuan. The specific planting process is as follows:

[0045] (1) Select the planting place

[0046] Select a relatively humid (soil moisture content greater than 15%) site in an area with an annual average temperature greater than 16°C, an annual average air relative humidity greater than 17%, and an annual average rainfall greater than 1000 mm as the planting site for Dendrobium candidum;

[0047] (2) Soil preparation

[0048] a. Plowing: Choose to use a machine plow on a sunny day, and the plowed soil will be fully exposed to the sun to kill s...

Abstract

The invention discloses a normalized cultivation method for field cultivation of dendrobium officinale, and aims at providing a normalized cultivation method for field cultivation of dendrobium officinale which is high in product quality. The method comprises the first step of planting field selection, the second step of soil preparation, the third step of plastic tunnel build, the fourth step of matrix treatment, the fifth step of matrix laying, the sixth step of transplanting, the seventh step of field management and the eighth step of harvesting. The normalized cultivation method for the field cultivation of the dendrobium officinale is not only suitable for promotion cultivation in flat areas and gentle slope zones, but also suitable for the promotion cultivation in mountainous areas and hilly zones which are good in natural ecological environment. The influence of terrains on the cultivation method is small, the adaptability is strong, the cultivation method is suitable for promotion of artificial normalization and large-scale cultivation of the dendrobium officinale, the produced dendrobium officinale can meet the requirements of markets, and products with high quality can be provided for the markets.

Description

technical field [0001] The invention relates to the technical field of dendrobium candidum planting, in particular to a standardized cultivation method for ground planting of dendrobium candidum. Background technique [0002] Dendrobium officinale Kimura et Migo, also known as black knot grass and Yunnan iron bark, is a perennial epiphytic herb of Orchidaceae, and its dried stems are used as medicine. It is the ultimate product in traditional Chinese medicine for nourishing yin, tonifying deficiency and nourishing the five internal organs. It is commonly known as "life-saving celestial grass" among the people. As early as the end of the Western Han Dynasty, "Shen Nong's Materia Medica" recorded Dendrobium candidum as a top grade: "mainly in the injury, eliminates numbness, lowers qi, nourishes the five viscera due to fatigue and emaciation, strengthens yin, and thickens the stomach after long-term use." The "Tao Zang" in the Kaiyuan period of the Tang Dynasty called Dendrob...
