Description

A kind of nutrient matrix and preparation method for dendrobium candidum soilless culture
Technical field
The invention belongs to officinal dendrobium stem plantation technical field, in particular it relates to a kind of for dendrobium candidum soilless culture Nutrient matrix and preparation method.
Background technology
Dendrobium candidum is one of most precious Chinese medicine in China, is classified as " Chinese nine big celestial grass " by honor（Dendrobium candidum, Tianshan Mountains Saussurea involucrata, three double ginsengs, 120 years tubers of multiflower knotweed, the Poria cocos of cycle of sixty years, desert cistanche, remote mountains ganoderma lucidum, seabed pearl, cordyceps sinensis）First of, It is known as the laudatory title of " gold in medicine ".《Chinese pharmacy dictionary》Dendrobium candidum is claimed " specially to grow the gas-liquid of lung stomach, gas-liquid rushes prosperous, kidney water It is spontaneous ", it is good at nourishing Yin and promoting production of body fluid, treats all diseases of Yin and fluid deficiency.In addition, dendrobium candidum is reinforcing stomach reg fluid medicine.《Sheng Nong's herbal classic》、 《Book on Chinese herbal medicine is new again》In it is on the books, appellation " medicine for enterogastritis, is to treat the common drug that epigastric pain, upper abdomen are gone up painful.Modern medical experiment Confirm：Dendrobium candidum has good inhibiting effect to pathogenic bacteria helicobacter pylori common in the spleen-stomach diseases, helps to treat atrophy The illness of the Helicobacter pyloris such as property gastritis, superficial gastritis, duodenal ulcer.
Dendrobium candidum uses cultivation technique without soil, is remarkably improved yield, promotes quality, reduces a variety of soil-borne diseases, only Change planting environment, expand plant application scope, there is vast potential for future development.
Matrix is the basis of soilless culture, is water, gas, the somatomedin of fertilizer that stable coordination can be provided for plant.Meanwhile Substrate culture is a kind of facility cultivation mode that popularizing area is maximum in soilless culture, it be the root system of plant is fixed on it is organic Or in inorganic matrix, by drip irrigation or the method for trickle irrigation, supply plant nutrient.Root system of plant is directly to contact with matrix , and moisture, nutrient are absorbed from matrix, so, the quality of matrix physicochemical property directly determines the good of vegetation growth state It is bad.
Therefore, researching and developing a kind of matrix for dendrobium candidum soilless culture turns into the heat of technical field of crop cultivation research and development Point.
