Embodiment 1

[0021] A cultivation substrate for raising seedlings of Dendrobium candidum, comprising the following raw materials: peat, bagasse, pine bark, carboxymethyl cellulose-montmorillonite intercalation compound, bacterial cellulose, EM inoculum, including peat, bagasse, and pine The mass ratio of bark, carboxymethyl cellulose-montmorillonite intercalation compound, bacterial cellulose, and EM bacterial agent is 30:10:10:5:1:1.

[0022] The preparation method of the carboxymethyl cellulose-montmorillonite intercalation composite is as follows: weigh 2 parts by mass of carboxymethyl cellulose and 10 parts by mass of montmorillonite to prepare 1.5% carboxymethyl fibers respectively. After mixing evenly, the nutrient solution and the montmorillonite suspension with a mass fraction of 4% are stirred and reacted for 6 hours at a temperature of 60°C and a pH of 7, then centrifuged, washed, and dried to obtain; the effective activity of EM bacteria The number of bacteria is 5×10 9 CFU / g.

Abstract

The present invention discloses a cultivation substrate for raising seedlings of dendrobium officinale. The cultivation substrate for raising seedlings of dendrobium officinale comprises the followingraw materials: peat, bagasse, pine bark, a carboxymethyl cellulose-montmorillonite intercalation compound, bacterial cellulose and a microbial inoculans; and a mass ratio of the peat, bagasse, pine bark, carboxymethyl cellulose-montmorillonite intercalation compound, bacterial cellulose and microbial inoculant is (20-40):(5-15):(5-15):(2-6):(0.5-2):(0.5-2). The present invention also discloses apreparation method of the cultivation substrate for raising seedlings of dendrobium candidum. The cultivation substrate can increase a transplanting survival rate of dendrobium candidum tissue cultureseedlings, can also promote growth and development of the seedlings, and has a good seedling raising effect.

Description

Technical field [0001] The invention relates to the technical field of Dendrobium officinale seedling raising, in particular to a cultivation substrate for Dendrobium officinale seedling raising and a preparation method thereof. Background technique [0002] Dendrobium officinale is an epiphytic herb of the orchid family. It is a traditional and precious Chinese medicine in my country with high medicinal and economic value. In recent years, with the discovery of anti-tumor, anti-aging, immunity and other health benefits of Dendrobium officinale, its market has gradually expanded and the demand for Dendrobium officinale seedlings has also increased. In order to improve the adaptability of Dendrobium officinale seedlings to greenhouse cultivation, the method of transplanting tissue culture seedlings into a cultivation substrate for domestication can be adopted. The cultivation substrate is a key link that affects the effect of domestication and nursery. At present, the cultivation...
