Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with specific embodiments.

[0021] Substrate preparation: wood processing plant leftovers and broken bark are mixed, crushed and then exposed to the sun, sprayed with 0.6% potassium permanganate for disinfection, sprayed with 120 times aqueous solution of EM bacteria original dew and stirred evenly, stacked, and covered with film for 8 days. Level the land, cover with a film, pour the fermented substrate, and form a seedbed with a width of 1.3m and a height of 13cm, and set it aside. Build a 3m-high plastic greenhouse with a shading net covering 70% of the shading rate on the roof, and install sprinkler irrigation and temperature and humidity control equipment.

[0022] Plant wild seedlings of Dendrobium officinale in the seedbed matrix with a density of 100 plants / m 2 , carry out normal water and fertilizer management and pest control. If the wild seedlings are weak, they can be soaked in 90mg / L ...

Abstract

The invention relates to a protecting and artificial feeding method for wild dendrobium candidum stock seeds. The method comprises the following steps of: (1) clearing up a seedbed and establishing a greenhouse; (2) cultivating and managing wild seedlings; (3) promoting flowering and fruiting; (4) performing tissue culture and raising seedlings; (5) exercising the tissue culture seedlings; (6) cultivating and managing the tissue culture seedlings; and (7) forming seedlings. The matrix is a mixture of sawdust and broken bark and is formed by spraying 120 times aqueous solution of EM bacteria stock dew, stirring uniformly, stacking, covering a film and fermenting; and in artificial pollination, lycopodium spores with an amount which is 4 to 6 times of pollen quantity is added into the collected pollen, and flower buds are sprayed by using a powder blower. The method has the beneficial effects that: the basic hereditary characters of the formed seedlings are close to those of the wild seedlings and stable; the survival rate of the formed seedlings is high and can reach 95 percent, and the fruiting rate can reach 40 percent; and the seedlings suffer from little pest and disease damage in the whole growth period, are grown regularly, and are high in growth speed and high in yield.

Description

1. Technical field [0001] The invention relates to a method for protecting and artificially cultivating wild dendrobium officinale original species. 2. Background technology [0002] Dendrobium is a herbaceous plant belonging to the family Aerial Orchidaceae. It is a traditional precious Chinese medicine in my country. It has been recorded in ancient Chinese medicine classics "Shen Nong's Materia Medica" and "Compendium of Materia Medica". There are hundreds of varieties, among which Dendrobium officinale is the best among many Dendrobium. Dendrobium candidum is called Tiepi Fengdou (dragon head and phoenix tail) after removing fibrous roots and drying. Physicians of all dynasties have highly praised it and regarded it as "the fairy product in medicine". The Taoist classic "Dian Cang" lists Tiepi Fengdou, Tianshan Snow Lotus, Sanliang Ginseng, Cordyceps sinensis, submarine pearls, and century-old Shouwu as the nine "immortal grasses" in China. Because of the very special a...
