Novel column-shaped three-dimensional cultivation method and device for medical dendrobium

Abstract

The invention provides a novel column-shaped three-dimensional cultivation method and device for medical dendrobium. The method is characterized by comprising the following steps of making a cultivation device serving as an auxiliary article in a hollow column-shaped body structure; filling a cultivation medium in the interior cavity of the hollow column-shaped body, wherein the hollow column-shaped body is at least 0.5 m in height and at least 8 cm in diameter, the external surface of the hollow column-shaped body is uniformly provided with seedling planting areas, and a cultivation medium composition mainly comprises the following raw materials in parts by volume: 5-15 parts of barks, 10-30 parts of saw dust and 3-10 parts of vermiculite; selecting healthily-growing seedlings to be hardened and then washing the hardened seedlings during cultivating and transplanting the dendrobium seedlings; and after sterilizing by using 800-1000 times of liquid carbendazim, transplanting the seedlings in different plant bunches according to the seedling planting areas, wherein row spaces of the transplanted plants are 4-6 cm*10-15 cm. Compared with the prior art, the cultivation method provided by the invention is very suitable for growth habits of the wild medical dendrobium; and the medical dendrobium cultivated by using the invention has the advantages of easiness for material obtaining, low cost, long service life, good water retention and fertilizer securing effects, high planting density, land utilization rate capable of being increased by 6-7 times, high and stable yield, good product quality and convenience for management.

Description

(1) Technical field [0001] The invention relates to a technique for planting traditional Chinese medicinal materials, in particular to a new columnar three-dimensional cultivation method and a cultivation device for medicinal Dendrobium officinalis. (two), background technology [0002] Dendrobium (Dendrobium) is one of the largest genus of Orchidaceae. Dendrobium plants are subtropical epiphytes. Most of them grow in subtropical regions with high humidity and deep mountain forests with sufficient scattered light, and they grow epiphytes on tree trunks or branches. , or grow in the crevices or troughs of mountain rocks in the forest. Dendrobium is a commonly used precious Chinese medicinal material with high medicinal value. It has the functions of enhancing immunity, strengthening yin and replenishing essence, promoting body fluid and nourishing stomach, moistening lung and relieving cough. There are dozens of varieties of Dendrobium, among which Dendrobium candidum and De...

Problems solved by technology

Through years of exploration, the artificial planting bases of Dendrobium have been successively established in various places. The conventional cultivation method is still: planting in the borderland of a large field shed, or erecting a flat planting bed for cultivation. Problems such as low rate and low output

Although some places also adopt other methods: that is, the cultivation method that can imitate the biological characteristics of wild Dendrobium as far as possible, such as: some adopt to tie the Dendrobium seedlings to be wrapped around the trunk, and some adopt to plant the Dendrobium seedlings in solid wall holes or use elevated The medium method of cultivating soil in horizontal grooves is to tie Dendrobium seedlings around the trunk. This method mainly has problems such as slow growth and low survival rate. It is also difficult for farmers to have forest tree trunks that are suitable for the growth of Dendrobium seedlings and have high humidity. To achieve the purpose of high yield, the cultivation method of planting Dendrobium seedlings in solid wall holes or in elevated horizontal groove culture soil has problems such as high cost of facilities and low utilization rate, and the planting effect of high and stable yield is more difficult to idealize

[0004] To sum up, in the current conventional cultivation methods, there are mainly problems such as low site and facility utilization in field facility planar cultivation, and three-dimensional cultivation technology is limited by site facilities with tree trunks, or high cost of site facilities, slow growth and low utilization rate, etc. , and complex field management (watering, topdressing, weeding, adjusting shading, pruning and turning, pest control) and other issues
