Abstract

The invention relates to the technical field of artificial cultivation of Chinese medicinal materials, in particular to a method for preparing a planting substrate used in the artificial cultivation of a Chinese medicinal material, i.e. dendrobium officinale. Currently, the substrates used in the artificial cultivation of dendrobium officinale mainly are tree barks, saw dust, water mosses, peat soil and river sand, wherein the substrates most suitable for growth of dendrobium officinale are the water mosses, the tree barks and the saw dust. The water mosses can be used after being washed and sterilized simply, but have higher price so that the planting cost cannot be accepted by most manufacturers. Compared with the water mosses, the tree barks and the saw dust have obvious advantages on the price, but the tree barks and the saw dust need to be subjected to fermentation treatment before being used and in the fermenting process, the fermentation of the tree barks is more difficult than that of the saw dust. The method can process the saw dust more easily and solve the substrate problem in the planting process of the dendrobium.

Description

The method for preparing dendrobium officinale culture medium

Technical field

Patent application of the present invention relates to a kind of artificial cultivation technique field of traditional Chinese medicine, relates in particular to the making of plantation matrix in the artificial cultivation of traditional Chinese medicine dendrobium candidum.

Background technology

Dendrobium candidum is first of the Chinese ten immortal grass, because the natural propagation rate is low, along with the increase of market demand amount, its wild resource is owing to excessively gather, near disappearance.In order to develop this famous and precious traditional Chinese medicine, many in recent years producers are studied its artificial planting technique, yet, therefore plant the critical problem that is selected to the artificial propagation of restriction dendrobium candidum of matrix because the root system of dendrobium candidum has the dual-use function of breathing and Nutrient Absorption.

The matrix species that is used for the dendrobium candidum plantation at present is various, and the dendrobium candidum growing way on the common matrix is general, and generally uses chemical fertilizer, waits the agricultural chemicals method to promote dendrobium candidum growth and damage by disease and insect to prevent, because matrix is unreasonable, causes the yield and quality of dendrobium candidum all very undesirable.

The matrix of using in the dendrobium candidum artificial planting at present mainly contains, bark, and wood chip, sphagna, peat soil, river sand, wherein the matrix of suitable growth is sphagna, bark and wood chip.The sphagna moss can use through after simple washing and the sterilization, but therefore its price comparison height causes planting cost that most of producers can not be accepted; Bark, wood chip are compared with sphagna has remarkable advantages on price, but bark and wood chip needed to handle by fermentation before using, and the bark fermentation will be difficult to wood chip during the fermentation.

Summary of the invention:

For this rare traditional Chinese medicine of better development, our company sums up the preparation method that a cover is fit to the plantation matrix of dendrobium candidum growth in long-term dendrobium candidum planting process.

Its method can directly arrive near wood-working factory's purchase at first selecting to be used for the pine sawdust of dendrobium candidum plantation, and select larchen wood chip during purchase is best wood chip with Korean pine and larix olgensis and masson pine wherein as far as possible.

Material is prepared: the wood chip that is used to ferment must be the new wood chip of buying, and cow dung before use must be earlier through high-temperature sterilization treatment.

After the material preparation, at first the wood chip that will newly buy presses 0.5 to 2kg/m ³Ratio add 1% urea liquid, press 200L/m at last ³Ratio add clear water, adjust wood chip water content to 60%; Then the wood chip that mixes is piled heap, size must not be less than 1 cubic meter, and fermentation time is 15-30 days for the first time, and fermentation temperature is 60-70 ℃.

Need to carry out turning after fermentation is finished for the first time, and add high temperature sterilization cow dung afterwards according to 3: 1 ratio, adjusting water content is about 60% back heap heaps, carries out the fermentation of second stage.

Ferment and carry out the turning second time after 15 days, the fermentation in 15-30 days of fermenting once more can be finished.The wood chip that ferments is for coffee-like, and the urine that there is no ammonia is disturbed flavor.

Claims

1. one kind prepares the method that dendrobium candidum is planted matrix, and its feature comprises following step:

A. the selection of wood chip: the wood chip that is used for the dendrobium candidum plantation is mainly Korean pine or larix olgensis based on pine sawdust;

B. the wood chip that is used to ferment is characterized in that it must being the wood chip of new production, and pilling up time is in 1 month;

C. the pre-treatment of fermenting: the wood chip that will newly buy, by 0.5 to 2kg/m ³Ratio add 1% urea liquid, at last by (100-200) L/m ³Ratio add clear water, adjust wood chip water content to 60%;

D. the wood chip that mixes is piled heap, size must not be less than 1 cubic meter, begins fermentation for the first time after heap is good;

E. after fermenting 15 days, carry out the turning first time, add through the cow dung of super-dry sterilization according to 3: 1 volume ratios and carry out the fermentation second time, fermentation time is 1-2 month, and intercycle, row carried out turning.

F. the wood chip that ferments is for coffee-like, and the urine that there is no ammonia is disturbed flavor.

2. according to the making of claim 1 sterilization cow dung, the method for disinfection that it is characterized by cow dung is 100 ℃ of thermophilic digestions 2 hours.

3. the matrix that ferments can be directly used in the dendrobium candidum plantation, can dry under the sun as can not in time using, then pack or heap heap kept dry.
