Dendrobium candidum planting method

Abstract

The invention discloses a dendrobium candidum planting method. The method comprises the steps that A, hollow bricks are placed on a mulching film; B, flowerpots are placed on the hollow bricks, and matrix is a product obtained by mixing and processing pine bark, soybean straws and wheat straws with the proportion of 4-6 to 1.2-1.5 to 1; C, field planting is conducted; D, watering is conducted; E fertilizer is applied, and the applied fertilizer is ecological organic fertilizer obtained by mixing and processing sheep manure, bean pulp and sheep manure leavening agents with the weight ratio of 900-1100 to 15-20 to 1; F, disease and pest control is conducted, and prevention and cure of leaf surfaces are conducted by spraying bactericide monthly; G, temperature and humidity control is conducted, and it is guaranteed that the temperature in a greenhouse is kept at 18-22 DEG C during daytime and 15-20 DEG C at night and the humidity in the greenhouse is kept at 60%-80%. By means of the method, dendrobium candidum is less susceptible to diseases, the polysaccharide content of the obtained dendrobium candidum can reach 29% or more, and the content of amino acid and microelements of the obtained dendrobium candidum is higher than that of wild dendrobium candidum.

Description

technical field [0001] The invention relates to a planting method, in particular to a planting method of dendrobium officinale, belonging to the technical field of plant cultivation. Background technique [0002] Dendrobium is a perennial epiphytic herb of the Orchidaceae Dendrobium genus Dendrobium, and is a traditionally commonly used precious Chinese medicinal material in my country. As early as in "Shen Nong's Materia Medica" and "Compendium of Materia Medica", it was listed as a top-grade medicinal material. Dendrobium is used as medicine with stems, containing various alkaloids such as dendrobine, dendrobium amine, dendrobine, and dendrobium; it is sweet and light in taste, slightly cold in nature; it has the effects of nourishing yin and nourishing stomach, clearing heat and promoting body fluid, mainly for the digestive system, respiratory system, Diseases such as cardiovascular and ophthalmology have obvious therapeutic effects. Modern medicine has proved that Den...

Problems solved by technology

Due to the special growth conditions and distribution limitations of wild Dendrobium candidum, and after long-term excavation, the natural resources are on the verge of exhaustion, and the domestic market is in short supply. Therefore, in recent years, many researchers have continued to explore the tissue culture and artificial planting of Dendrobium candidum. Although some achievements have been made, there are still problems such as low survival rate, slow growth, low yield, and insufficient nutritional components of Dendrobium in short-term harvesting during the transplanting process of tissue culture seedlings, which seriously restrict the industrialization and large-scale development of Dendrobium.

[0004] Although artificial planting has made a great contribution to the output of Dendrobium nodrobii, because the dendrobium nodrobium grows fast, so the harvest is also fast, the main active ingredient content of the obtained Dendrobium candidum is much reduced, and its medicinal effect is also lower than that of wild dendrobium.
