Dendrobium huoshanense seedling domestication method

Abstract

The invention discloses a dendrobium huoshanense seedling domestication method. The dendrobium huoshanense seedling domestication method comprises the following steps of greenhouse construction, seedling bed frame construction, planting medium preparation, planting matrix preparation, planting medium and planting matrix pretreatment, seedling planting, seedling growth and seedling pulling aftertreatment. The dendrobium huoshanense seedling domestication method has the advantages that the water content is high, the water holding capacity is good, not only can water needed by normal growth of dendrobium huoshanense be provided, but also it can be guaranteed that roots of the dendrobium huoshanense cannot be rotten due to too much water, and therefore the dendrobium huoshanense seedling domestication cycle is greatly shortened; the dendrobium huoshanense seedling domestication cycle is shortened by a half, and therefore seedlings are short in buffer time and high in growth speed after being cultivated; in addition, usage of a cultivation matrix is reduced in the cultivation process, recycling of the medium is achieved in the cultivation process, and therefore both the cost and destruction of the ecological environment are reduced; furthermore, if the seedlings are transplanted after being directly domesticated through the method, the survival rate can reach up to 100%.

Description

technical field [0001] The invention relates to the technical field of planting and cultivation of dendrobium, in particular to a method for domesticating seedlings of dendrobium huoshanense. Background technique [0002] Dendrobium is a perennial herb of the family Orchidaceae. Huoshan Dendrobium, commonly known as "Mihu", is mainly distributed in Huoshan in the southwest of Anhui. Because of its alkaloids, crude polysaccharides, amino acids, trace elements and other components, it has the functions of strengthening kidney and essence, thickening stomach, inhibiting tumor cells, lowering blood sugar, It has been regarded as the first of the nine "immortal herbs" for its effects of enhancing immunity and relieving physical fatigue. [0003] For a long time, due to the harsh growth conditions of Dendrobium Huoshanense and people's over-harvesting, this species has been on the verge of extinction. Many companies and scientific research institutes have achieved species conser...

AI Technical Summary

Problems solved by technology

So far, the sales of Dendrobium seedlings mainly include tissue-cultured seedlings and domesticated seedlings. Tissue-cultured seedlings are seedlings obtained through tissue culture. The surviving seedlings have high transplanting survival rate, simple management, and low cultivation risk; among them, the substrate for the domestication of seedlings in the existing technology is mainly bark

[0004] The existing Huoshanense Dendrobium seedling domestication facilities are the same as the Huoshanense Dendrobium cultivation facilities, requiring bark substrate and cultivation facilities, wherein the bark substrate will be emptied every time the seedlings are domesticated, which cannot be reused, the cost is too high, and causes The shortage of bark resources causes serious waste; in addition, using bark as the domestication substrate of Dendrobium huoshanense seedlings takes a long period of domestication: the water content of bark is not easy to control, the water storage capacity is poor, and the surface of the seedlings is dry after planting. Generally, it will take 15 days to take root, and it will take about a month to germinate. Under the condition of suitable temperature and humidity, it will take at least about 3 months for the roots and buds to grow completely; root rot phenomenon
