Problems solved by technology

However, due to the incomplete understanding of Dendrobium officinale plants, blindly using existing cultivation substrates, fertilizers, etc. for seedling cultivation, the quality of Dendrobium officinale obtained is very poor, which does not meet the pharmacopoeia standards, and the drug effect is very unstable. , this way of development is detrimental to both sellers and buyers

Abstract

The invention relates to the technical field of modern agricultural industry, and discloses a cultivation substrate for raising high-quality seedlings of Dendrobium candidum. Easily available naturalingredients are adopted as raw materials, and treated corn cobs have good performance of water retention and fertilizer maintenance, so that growth and development of Dendrobium candidum are promoted,and cold resistance and drought resistance of root systems are facilitated; the substrate has good water drainage properties and good air permeability so that waterlogging can be prevented, and components required by growth of Dendrobium candidum can be released continuously by modified biomass carbon which can also be used as a carrier of insecticide; furthermore, the prepared cultivation substrate has low cost and can be applied to seedling cultivation for 3-4 cycles, and after subsequent blending is conducted, the substrate can be recycled; the Dendrobium candidum seedlings cultured by theprepared cultivation substrate has a growth rate faster than the growth rate of wild Dendrobium candidum by 1.5-1.8 times, a high survival rate, low morbidity, a good growth trend and high content ofpolysaccharide are achieved, species resources and technical data are provided for selection and cultivation of high-quality high-yield Dendrobium candidum, and sustainable development and utilization of Dendrobium candidum resources can be achieved; and a technical scheme worthy of promotion and application is provided.

Description

technical field [0001] The invention belongs to the technical field of modern agricultural industry, and in particular relates to a high-quality cultivation substrate for dendrobium officinale seedling raising. Background technique [0002] Dendrobium, one of the Orchidaceae plants, is mainly distributed in tropical and subtropical Asia, Australia and Pacific Islands, and most of our country is distributed in Southwest, South China, Taiwan and other places. The main varieties of Dendrobium are Dendrobium nobile, Dendrobium dendrobii, Dendrobium drumstick and so on. It can be used as medicine, and it is called Dendrobium, which has the effects of dispelling asthenic heat, benefiting essence and strengthening yin to the human body. With the rise of the flower industry, Dendrobium has also become an ornamental plant. Dendrobium orchids are generally grown in pots. Dendrobium is known as the flower of the father because of its strong and amiable temperament. The plant of Den...
