Embodiment 1

[0033] 1. Artificial pollination and seed preservation

[0034] Robust and disease-free Dendrobium candidum were selected, artificially pollinated during flowering, and well-developed fruit pods were harvested 5 months after artificial pollination, dried in a cool place, and then stored at 4°C.

[0035] 2. Seedbed arrangement

[0036] Choose the seedbed of the steel frame greenhouse. The seedbed is 30m long, 1.5m wide, and 1.2m high. Spread the plastic paper on the seedbed, and fix the plastic paper around the edge of the seedbed with thin wooden strips to ensure that the seedbed can maintain a height of 2cm. water.

[0037] 3. Treatment of Live Substrate

[0038] Mix medicinal residues, coconut bran, and fermented peat soil in a volume ratio of 1:10:15, and mix the resulting mixture with carbendazim and phoxim in a volume ratio of 1000:3:3 to prepare a live broadcast substrate ; Fill the seedling cultivation tray with the live broadcast substrate, after flattening and compac...

Embodiment 2

[0046] 1. Artificial pollination and seed preservation

[0047] Robust and disease-free Dendrobium candidum were selected, artificially pollinated during flowering, and well-developed fruit pods were harvested 5 months after artificial pollination, dried in a cool place, and then stored at 0°C.

[0048] 2. Seedbed arrangement

[0049] Choose the seedbed of the steel frame greenhouse, the seedbed is 40m long, 2m wide, and 1m high, spread the plastic paper on the seedbed, and fix the plastic paper around the edge of the seedbed with thin wooden strips to ensure that the seedbed can maintain 1cm high water.

[0050] 3. Treatment of Live Substrate

[0051] Mix medicinal residues, coconut bran, and fermented peat soil in a volume ratio of 1:10:10, and mix the resulting mixture with carbendazim and phoxim in a volume ratio of 1000:3:3 to prepare a live broadcast substrate ; Fill the seedling cultivation tray with the live broadcast substrate, after flattening and compacting, place...

Embodiment 3

[0059] 1. Artificial pollination and seed preservation

[0060] Robust and disease-free Dendrobium candidum were selected, artificially pollinated during flowering, and well-developed fruit pods were harvested 4 months after artificial pollination, dried in a cool place, and then stored at 4°C.

[0061] 2. Seedbed arrangement

[0062] Choose the seedbed of the steel frame greenhouse, the seedbed is 35m long, 1.8m wide, and 0.8m high, spread the plastic paper on the seedbed, and fix the plastic paper around the edge of the seedbed with thin wooden strips to ensure that the seedbed can maintain a height of 1.5cm of water.

[0063] 3. Treatment of Live Substrate

[0064] Mix medicinal residues, coconut bran, and fermented peat soil in a volume ratio of 1:5:20, and mix the resulting mixture with carbendazim and phoxim in a volume ratio of 1000:3:3 to prepare a live broadcast substrate ; Fill the seedling cultivation tray with the live broadcast substrate, after flattening and c...

Abstract

The invention discloses a greenhouse direct-seeding reproduction method for dendrobium officinale. According to the method, dendrobium officinale capsules are used as materials, at first, special phytohormone is used for treating dendrobium officinale seeds, a specific direct-seeding matrix is selected, the emergence rate of the dendrobium officinale seeds directly sown is 80% or above, and then by selecting a specific transplanting matrix, the survival rate of transplanted dendrobium officinale seedlings is 100% nearly. The method is simple, easy to implement and low in cost, the seedlings emerge fast, the seedling emergency rate is high, transplanted plants grow fast, the whole seedling culture period is short, the method is suitable for factorized rapid reproduction and large-scale field production, the requirement for planting dendrobium officinale in a large-area and large-scale mode can be met, a new path is opened up for rapid sexual reproduction of dendrobium officinale, and the method has double significance in production and economy.

Description

technical field [0001] The invention belongs to the technical field of artificial planting of medicinal plants, and in particular relates to a greenhouse direct seeding propagation method of the endangered medicinal plant Dendrobium candidum. Background technique [0002] Dendrobium officinale Kimura et Migo is a perennial herb of the genus Dendrobium orchidaceae, mainly distributed in Yunnan, Anhui, Guizhou, Zhejiang, Jiangxi and other places, and is a rare Chinese medicinal material. Because of its functions of nourishing yin and clearing away heat, promoting body fluid and benefiting the stomach, nourishing the lungs and relieving cough, it ranks first among the "Nine Chinese Immortal Herbs" and was included in the 2015 edition of the Pharmacopoeia. Its main medicinal components are Dendrobium officinale polysaccharides, alkaloids, amino acids and other trace components. Modern pharmacology shows that Dendrobium officinale has the functions of anti-tumor, anti-oxidation,...
