Problems solved by technology

[0004] Due to the low natural reproduction rate of Dendrobium officinale, the seedlings used in large-scale production are all tissue culture seedlings. The traditional method of epiphytic cultivation of Dendrobium officinale is to plant Dendrobium officinale seedlings directly on the cliff, and Dendrobium officinale seedlings are adapted to The ability to cultivate high temperature, drought and other harsh environments on cliff walls is weak, which leads to low survival rate of Dendrobium officinale seedlings cultivated on cliff walls, reduces the yield and economic benefits of Dendrobium officinale cultivated on cliff walls, and limits the development of the epiphytic cultivation of Dendrobium candidum on cliff walls.

Embodiment 1

[0024] 1) Planting site preparation: choose a cliff with an altitude of 300 meters, sit north to south and east 10 degrees, with a slope of 90 degrees, and a relatively flat slope as the planting site for Dendrobium candidum; In the well-shaped way, nails are used to fix the wooden strips on the cliff surface. The wooden strips used for fixing are 2m long and 3cm thick.

[0025] 2) Planting of Selaginella: In November, select Selaginella whose main stem is more than 3cm long, use the wooden strips on the cliff as supports, attach the soil-bearing root system of Selaginella to the cliff, and place it on a wooden frame and In the gap between the wooden frame and the cliff, the horizontal distance between the selaginellas is 30cm; after the planting, the water is replenished by spraying, and the water is sprayed every 2 days, and the water is not sprayed on cloudy and rainy days until the leaves of the selaginella are stretched and the selaginella survives.

Embodiment 2

[0030] 1) Preparation of the planting site: Choose a cliff with an altitude of 300 meters, facing south and east 30 degrees, with a slope of 70 degrees, and a relatively flat slope as the planting site for Dendrobium candidum; In a well-shaped way, nails are used to fix the wooden strips on the cliff surface. The wooden strips used for fixing are 2.5m long and 2.5cm thick.

[0031] 2) Planting of Selaginella: In November, select Selaginella with a main stem longer than 3cm, attach the root system of Selaginella to the cliff, and place it in the wooden frame and the gap between the wooden frame and the cliff. The horizontal distance between them is 35cm; after planting, spray water to replenish water, spray water once every 2 days, and do not spray water on rainy days until the leaves of Selaginella are stretched and Selaginella survives.

[0032] 3) Preparation before planting of Dendrobium candidum: After the new branches of Dendrobium candidum are capped in winter, in the mi...

Abstract

The invention relates to a method of using Selaginella tamariscina as epiphytic object to cultivate Dendrobium officinale on cliff faces and belongs to the technical field of cultivation of Dendrobiumofficinale. The method comprises: planting the epiphytic object, Selaginella tamariscina, to a cliff face; planting Dendrobium officinale epiphytically to main stems of Selaginella tamariscina. The parts of Dendrobium officinale, such as leaves and main stems, are utilized to provide supporting, shading, water holding, water repelling, nutrition and the like for Dendrobium officinale; the commonadverse factors, such as high temperature, drought, and excessive damp, in the cliff-face epiphytic cultivation of Selaginella tamariscina are overcome; the survival rate and yield of Dendrobium officinale under wild-like cultivation on cliff faces are significantly increased; good quality of Dendrobium officinale under wild-like cultivation on cliff faces is maintained.

Description

technical field [0001] The invention relates to the technical field of cultivation methods of Dendrobium candidum, in particular to a method for growing Dendrobium candidum on cliff walls by using Selaginella as an epiphyte. Background technique [0002] Dendrobium officinale (Dendrobium officinale), also known as black knot grass, is a perennial epiphytic herb of the Orchidaceae family (Orchidaceae). Since Dendrobium officinale is an orchid plant, its seeds are small and do not contain endosperm. It needs to symbiosis with fungi to germinate, and its natural reproduction rate is low. As early as 1987, Dendrobium officinale was included in the "National Key Protected Wild Medicinal Species List". Since the 21st century, breakthroughs in key artificial breeding technologies such as seed production, tissue culture, and facility cultivation of Dendrobium candidum have led to strong growth in the efficient planting and industrial development of Dendrobium candidum. [0003] The...
