Embodiment 1

[0031] A kind of method adopting hydrophilic polyurethane foam to plant dendrobium officinale, specifically comprises the following steps:

[0032] (1) Greenhouse construction: The greenhouse is 10m wide, 4m high, and 25m long. A layer of shading net with a shading degree of 70% is laid 1m above the top of the greenhouse, and a layer of shading net with a shading degree of 70% is laid 2.5m above the ground in the greenhouse. shade net.

[0033] (2) Cultivation substrate preparation: select 10cm thick hydrophilic polyurethane foam as the cultivation substrate, after the hydrophilic polyurethane foam is cut and opened for planting, soak for 1 hour with nutrient solution, and then place it on the tray of the seedbed, the seedbed is Flat type, the tray is pre-padded with a layer of 5cm thick pine bark. The pine bark is first crushed into small pieces, and after high-temperature distillation, it is sterilized with 0.3% potassium permanganate solution to control the water content t...

A layer of shading net with a shading degree of 75% is laid 1.5m above the top of the greenhouse, and a layer of shading net with a shading degree of 75% is laid 2.5m above the ground in the greenhouse. % shade net.

[0046] (2) Cultivation substrate preparation: use 11cm thick hydrophilic polyurethane foam as the cultivation substrate. After the hydrophilic polyurethane foam is cut and the planting holes are opened, it is soaked in nutrient solution for 1.5 hours, and then placed on the tray of the seedbed. It is a flat type, and the tray is pre-padded with a layer of 5cm thick pine bark. The pine bark is first crushed into small pieces, and after high-temperature distillation, it is sterilized with 0.3% potassium permanganate solution to control the ...

Embodiment 3

[0057] A kind of method adopting hydrophilic polyurethane foam to plant dendrobium officinale, specifically comprises the following steps:

[0058] (1) Greenhouse construction: the greenhouse is 12m wide, 6m high, and 35m long. A layer of shading net with a shading degree of 80% is laid 2m above the top of the greenhouse, and a layer of shading net with a shading degree of 80% is laid 3m above the ground in the greenhouse. Shade net.

[0059] (2) Cultivation substrate preparation: select 12cm thick hydrophilic polyurethane foam as the cultivation substrate. After the hydrophilic polyurethane foam is cut and opened for planting, it is soaked in nutrient solution for 2 hours, and then placed on the tray of the seedbed. The seedbed is Flat type, the tray is pre-padded with a layer of 6cm thick pine bark. The pine bark is first crushed into small pieces, and after high-temperature distillation, it is sterilized with 0.3% potassium permanganate solution to control the water conten...

Abstract

The invention discloses a method for planting dendrobium candidum by adopting hydrophilic polyurethane foam. The method comprises the steps: constructing a dendrobium candidum planting greenhouse; preparing a culture medium; transplanting tissue culture seedlings; carrying out water and fertilizer management; harvesting and the like. By adopting hydrophilic polyurethane foam as the culture medium, the problem that the culture medium has poor air permeability and poor water retention at the root position in a fixed planting process of the dendrobium candidum tissue culture seedlings is solved; meanwhile, the dendrobium candidum is cultured by using a selenium-containing nutrient solution, so that the selenium content of the dendrobium candidum is improved and the economical value of the dendrobium candidum is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for planting dendrobium officinale by using hydrophilic polyurethane foam. Background technique [0002] Dendrobium candidum, also known as black knot grass, is a perennial epiphytic herb of the genus Dendrobium orchidaceae. It is named for its iron-green skin. It is a precious wild medicinal plant and belongs to the second-class national key protected plant. "First, it is called "the giant panda in the medicine world" by the international medicinal plant community. Modern medical research shows that the main components of Dendrobium officinale are Dendrobium polysaccharides, Dendrobine, Dendrobium phenol, Dendrobium amine, amino acids, and special phenanthrene and bibenzyl anticancer ingredients. Its functions are mainly manifested in the effects of nourishing yin and clearing heat, nourishing the stomach and promoting body fluid, nourishing ...
