Ecological cultivation method for dendrobe

Abstract

The invention discloses an ecological cultivation method for dendrobe. The method comprises the following steps of stone selection and processing; land processing; fertilizer selection; seedling selection; cultivation; field management; wild environment growth. On the basis of growth characteristics of dendrobe, porous stone where wild Dendrobium officinale grows is selected, a layer of rice water is brushed on the surface of the stone, a small amount of water soluble fertilizer is scattered, land is sterilized, processed and placed at a clean river bank tree shade, natural growth is performed under the natural environment, the basic survival environment suitable for wild Dendrobium officinale growth is built, a dragon tree extract is added into the water soluble fertilizer, the dragon tree enhances the crop anti-bacteria and anti-adversity ability, the insect resistance, disease resistance, drought resistance, cold resistance, waterlogging resistance, dry hot wind resistance, salt and alkali resistance and continuous cropping resistance are improved so as to ensure the plant survival and final yield, the operation method is simple, the number of plant diseases and insect pests is small, the produced dendrobe and actual wild products hardly have no difference in medicinal value, and the method is suitable for large-scale popularization.

Description

Technical field [0001] The invention relates to the technical field of dendrobium cultivation, in particular to a dendrobium ecological cultivation method. Background technique [0002] Dendrobium is a traditional and precious Chinese medicinal material in my country, which has been recorded in the Chinese pharmacopoeia. The original plant of the traditional Chinese medicine Dendrobium is a perennial herb of the orchid family Dendrobium. Dendrobium is one of the relatively large genus of Orchidaceae. There are about 1,000 species in the world. There are 74 species and 2 varieties of Dendrobium in my country, of which more than 50 species are in commercial circulation. Among them, Dendrobium officinale is the most precious, the best quality of all Dendrobium. Dendrobium officinale is an endangered species, it is a second-level national key protected plant, and it is a rare and precious Chinese medicinal material. The ancient nobles called Dendrobium officinale as "zicaranda fai...

Problems solved by technology

[0003] Because the seeds of Dendrobium candidum are difficult to collect, the seed germination rate is low, and the seed propagation takes a long time to raise seedlings, which greatly increases the cultivation cost of Dendrobium candidum, which is not conducive to the artificial large-scale cultivation of Dendrobium candidum

Therefore, in the current artificial cultivation, the propagation mainly relies on division propagation and cutting propagation, but this method has a low propagation coefficient, is not economical, and limits the yield potential of Dendrobium candidum, which is inconvenient for planting management and promotion, thus inhibiting the expansion of cultivation area
