Problems solved by technology

Such matrix materials and proportions have defects such as poor air permeability and low humidity, which cannot meet the requirements of high humidity. Usually, it is necessary to use spraying to make the environment and matrix meet the humidity standard
However, excessive spraying increases the humidity of the overall environment in the greenhouse, which leads to serious breeding of diseases and insect pests and accelerates the aging of greenhouse facilities

Abstract

The invention discloses a cultivation substrate for dendrobium officinale. The cultivation substrate contains the ingredients in parts by weight: 1-8 parts of pine barks, 1-8 parts of sphagnum moss and 1-8 parts of bamboo charcoal. According to the cultivation substrate, the sphagnum moss has good water retention property and air permeability; the bamboo charcoal brings air permeability and attached weak acidity into full play; and the pine barks are filled and can play a role in fixing the dendrobium officinale. According to the cultivation substrate, the requirements of the dendrobium officinale on characteristics, i.e., air permeability and water retention property of the substrate are met, and problems that diseases and insect pests are propagated, the aging of greenhouse facilities is accelerated, and the like caused by the increase of internal overall ambient humidity of a greenhouse can also be avoided. In addition, the characteristic requirements that Orchidaceae plants like weak acidity are also met.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a cultivation substrate and a preparation method of dendrobium officinale. Background technique [0002] Dendrobium officinale is a perennial herbaceous plant of the genus Dendrobium in the family Orchidaceae. The wild Dendrobium candidum grows in a unique environment and has very strict requirements on the climate. It grows epiphytically on tree trunks or under forests. Because there is no stable and sufficient nutrient supply, there is no endosperm, the growth is slow, and the survival rate is extremely low. With the development of tissue culture technology, artificial cultivation of Dendrobium officinale becomes possible. The growth requirement of Dendrobium officinale is a warm, humid, ventilated and drained environment, so when artificially cultivating Dendrobium officinale, the choice of cultivation medium is very important. [0003] At present, the matrix materia...
