Cultivation method of dendrobium candidum

Abstract

The invention relates to a cultivation method of dendrobium candidum, comprising the following steps of: paving the ground: levelling a land, and then sequentially paving a quicklime powder layer, a gardening ground cloth, a gravel layer and a shading net layer from bottom to top; forming rectangular land; building a shed; selecting the specifications of species and germchits: selecting seed sources in Zhejiang and domesticated seedlings obtained by domesticating tissue culture seedlings transplanted out of bottles for more than one year; and culturing. In the invention, the layers of multiple-layer ground pavements are not mutually influenced, the gravel layer can be used as a water filtering layer to provide a good root growth environment for the dendrobium candidum, and the multiple-layer ground pavements also physically obstruct insect pest sources from underground to a peripheral space with a matched insect prevention measures together, thereby not only saving the cost by reducing the use amount of pesticides, but also greatly enhancing the edible safety of the dendrobium candidum. The cultivation method of the dendrobium candidum creates an optimal environment for the growthof the dendrobium candidum from roots and the ground aiming at the artificial cultivation of a rare and endangered traditional Chinese medicinal material, i.e. the dendrobium candidum, and is used for carrying out pest control by adopting a full-physical method, thereby effectively reducing the generation of plant diseases and insect pests and realizing the safe and efficient cultivation.

Description

technical field [0001] The invention belongs to the technical field of cultivation of traditional Chinese medicinal materials, and in particular relates to a cultivation method of dendrobium officinale. Background technique [0002] Since artificial cultivation was reported in 1990, the artificial cultivation methods of Dendrobium officinale have all been planted in protected land (with greenhouse facilities). There are mainly two methods: the ground in the greenhouse is laid with substrate to make a border and then planted directly; . Both of these two cultivation methods have their disadvantages: direct planting in greenhouses is likely to cause insect damage, especially underground pests and molluscs such as snails and slugs. In some mountainous areas, there are also ants. Once pests occur, chemical agents cannot completely eradicate them. Candidum candidum has pesticide residues while affecting the yield; direct planting can also cause poor drainage, cause root rot of D...

Problems solved by technology

Both of these two cultivation methods have their disadvantages: direct planting in greenhouses is likely to cause insect damage, especially underground pests and molluscs such as snails and slugs. In some mountainous areas, there are also ants. Once pests occur, chemical agents cannot completely eradicate them. Candidum candidum has pesticide residues while affecting the yield; direct planting can also cause poor drainage, cause rotten roots of Dendrobium candidum and induce disease; it is difficult to completely replace the substrate after a long period of direct planting, which is likely to cause continuous cropping-induced diseases

Greenhouse seedbed overhead container cultivation is extremely expensive, and the volume of the container limits the growth of Dendrobium officinale, resulting in relatively low input and output

Under the existing cultivation methods, the quality and food safety of artificially cultivated Dendrobium officinale cannot be guaranteed, and the production efficiency is low, which restricts the development of the entire industry
