The invention discloses a
dendrobium cultivating medium. The
dendrobium cultivating medium is prepared from pinecones,
wood shavings and
saw dust in a
mixed mode, wherein the volume of the pinecones accounts for 50% to 70% of the total volume of the medium, the volume of the
wood shavings accounts for 20% to 30% of the total volume of the medium, and the volume of the
saw dust accounts for 10% to 20% of the total volume of the medium. The pinecones need to be subjected to early-stage
processing; in other words, the pinecones need to be sterilized under the blazing sun for quite a long time or through boiling at high temperature; the
wood shavings and the
saw dust must be wood shavings and saw dust of pine trees or cedars and also must be subjected to early-stage
processing. According to the
dendrobium cultivating medium, in the main raw materials, the pinecones are waste in a
pine forest area, the wood shavings and the saw dust are waste of a wood-working factory, all the raw materials can be obtained in a large-scale mode, the pinecones are not prone to rotting or generating
insect damage, the service life of the medium is prolonged, and the cost of the medium is reduced; in addition, the air permeability of the pinecones is good, the good
moisture preserving and
fertilizer preserving characteristics are achieved, after the pinecones, the wood shavings and the saw dust are mixed to be used, the
plant fixing requirement can be guaranteed, dendrobium grows robustly, the
survival rate is high, the
root system is well developed, and the yield is high.
