Problems solved by technology

At present, there are many types of cultivation substrates for Dendrobium officinale. The growth of Dendrobium officinale on ordinary substrates is average, and it is easy to get some diseases and insect pests. It needs to be controlled by applying chemical fertilizers and pesticides in the later stage.

Embodiment 1-1

[0026] Embodiment 1-1: basic matrix preparation method:

[0027] 1. Preparation of rotten organic matter: After mixing pine wood chips and pine sawdust evenly, stack them in the open air for several days, then water them to make them soak, then cover them tightly with plastic film, and stack them for 3 months to half a year. Its rotten. After this treatment, because it has been exposed to the sun, and the high temperature generated by the fermented organic matter itself after covering with plastic film, it has a very good fumigation effect on the substrate. In this way, the organic matter can be decomposed to a high degree, loose and even.

[0028] 2. Mixing of substrate raw materials: uniformly mix the decomposed organic matter, vermiculite and peat at a volume ratio of 2:1:1 to obtain the basic substrate.

Embodiment 1-2

[0029] Embodiment 1-2: basic matrix preparation method:

[0030] 1. Preparation of rotten organic matter: After mixing pine wood chips and pine sawdust evenly, stack them in the open air for several days, then water them to make them soak, then cover them tightly with plastic film, and stack them for 3 months to half a year. Its rotten. After this treatment, because it has been exposed to the sun, and the high temperature generated by the fermented organic matter itself after covering with plastic film, it has a very good fumigation effect on the substrate. In this way, the organic matter can be decomposed to a high degree, loose and even.

[0031] 2. Mixing of substrate raw materials: uniformly mix the decomposed organic matter, vermiculite and peat at a volume ratio of 5:1:1 to obtain the basic substrate.

Embodiment 1-3

[0032] Embodiment 1-3: basic matrix preparation method:

[0033] 1. Preparation of rotten organic matter: After mixing pine wood chips and pine sawdust evenly, stack them in the open air for several days, then water them to make them soak, then cover them tightly with plastic film, and stack them for 3 months to half a year. Its rotten. After this treatment, because it has been exposed to the sun, and the high temperature generated by the fermented organic matter itself after covering with plastic film, it has a very good fumigation effect on the substrate. In this way, the organic matter can be decomposed to a high degree, loose and even.

[0034] 2. Mixing of substrate raw materials: uniformly mix the decomposed organic matter, vermiculite and peat at a volume ratio of 1:5:5 to obtain the basic substrate.

Abstract

The invention discloses a dendrobium officinale cultivation substrate and a preparation method of the dendrobium officinale cultivation substrate. The substrate is prepared from pine sawdust, pine saw powder, peat, vermiculite and pestalotiopsis mycorrhizal fungi. The preparation method comprises the following steps of (1) preparing decomposed organic matters by means of uniformly mixing the pine sawdust and the pine saw powder, stacking the mixture outdoors for a few days, watering the mixture to wet completely, tightly covering the mixture with a plastic film, stacking for three months or half a year, and thoroughly decomposing the mixture; (2) mixing substrate materials by means of uniformly mixing the decomposed organic matters, the vermiculite and the peat according to a volume ratio of 5:1:1 to 1:5:5; (3) adding the pestalotiopsis mycorrhizal fungi into the prepared basic substrate. The substrate disclosed by the invention not only has the advantages of good air permeability, high water-retaining property, low cost and the like, but also has the effect of promoting the growth of dendrobium officinale seedlings.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a dendrobium candidum cultivation substrate and a preparation method thereof. Background technique [0002] As a well-known traditional medicinal material in China, Dendrobium officinale has the functions of nourishing yin and nourishing the stomach, nourishing the lungs and relieving cough, clearing away heat and improving eyesight. In addition, it can also enhance human immunity, eliminate tumors, and inhibit cancer. As early as "Compendium of Materia Medica", Dendrobium candidum was listed as medicinal, and it was listed as top grade in "Shen Nong's Materia Medica". Shouwu, Shenshan Ganoderma lucidum, and Cordyceps sinensis are listed as the "Nine Great Immortal Grasses of China", and Dendrobium candidum is the first among the "Nine Great Immortal Grasses". Because Dendrobium candidum is very rare and precious, in recent years, the artificial cultivation industry of D...
