Problems solved by technology

[0003] The substrate for cultivating Dendrobium prepared by the prior art method also has defects in air permeability, fertilizer retention and water retention, and the cost is relatively high. In addition, the nitrogen, phosphorus and potassium fertilizers required for the growth period of Dendrobium are compared. Insufficient, and there is no filter layer to regulate the water content of the substrate in cultivation, and discharge excess water and nutrient solution. The harvesting period is generally only 2-3 years

Abstract

The invention discloses a dendrobium nobile culture substrate material. The dendrobium nobile culture substrate material is composed of three layers, and the three layers refer to the fertilizer substrate layer, the gravel layer and the filtering layer which is laid between the fertilizer substrate layer and the gravel layer; the fertilizer substrate layer is located on the topmost layer and is formed by mixing 20-50% of wood flour, 10-30% of bark, 5-10% of sawdust, 5-10% of brick granules, 5-10% of sphagna, 5-10% of corn straw and 20-30% of decomposed organic fertilizer; the decomposed organic fertilizer is formed by mixing cow dung, chicken manure, plant ash and sheep manure. The invention further discloses a preparation method of the dendrobium nobile culture substrate material. The dendrobium nobile culture substrate material has the advantages of being excellent in air permeability, fertilizer retention capacity and water-retaining property, low in cost and capable of providing N-P-K organic fertilizer required by the growth of dendrobium nobile, and the harvest period is shortened to about a year and a half.

Description

technical field [0001] The invention relates to the field of dendrobium substrates, in particular to a dendrobium substrate material and a preparation method thereof. Background technique [0002] Dendrobium, one of the Orchidaceae plants, is mainly distributed in tropical and subtropical Asia, Australia and Pacific Islands, and most of our country is distributed in Southwest, South China, Taiwan and other places. The main varieties of Dendrobium are Dendrobium officinale, Dendrobium nobile, Dendrobium dendrobii, Dendrobium drumstick and so on. It can be used as medicine, and has curative effects on the human body such as dispelling deficiency heat, benefiting essence and strengthening yin. Dendrobium candidum is a traditional and precious traditional Chinese medicinal material in my country. Among them, Dendrobium candidum has the functions of nourishing yin and nourishing stomach, moistening lung and relieving cough, anti-cancer and prolonging life, etc. Dendrobium nobile...
