Problems solved by technology

In the prior art, light cultivation is generally used, and the rooted seedlings are cultivated in the cultivation room for 3.5 to 4 months after taking root, then transplanted out of the bottle to the domestication greenhouse, and can be planted in the field through shading and hardening for about 2 months. The rate is not high, about 60%, and the growth cycle is long, and the production cost is high

Embodiment 1

[0017] Dendrobium officinale buds that have been multiplied and cultivated to a height of more than 3 cm are inoculated onto the MS rooting medium and cultivated in the culture room for 30 days until the seedlings take root to obtain rooted bottle seedlings; the conditions for culturing in the culture room are light for 8 hours / Day, light intensity 2000Lux, cultivation temperature 25°C. Then carry out low-light cultivation, transfer the rooted bottle seedlings from the cultivation room to the sunshine greenhouse, and cultivate them for 30 days at a temperature of 25°C and a light intensity of 8000 Lux until the root system of the seedlings grows, the leaves turn green, the height of the seedlings is 5 cm and the growth rate is 6-8. piece of leaf. Then carry out strong light cultivation, and cultivate for 20 days at a temperature of 28° C. and a light intensity of 10,000 Lux. When the seedlings are 7 to 8 cm in height and have 8 to 10 leaves, they can be planted out of the bot...

Embodiment 2

[0019] Dendrobium officinale buds that have been multiplied and cultivated to a height of more than 3 cm are inoculated onto the MS rooting medium and cultivated in the culture room for 30 days until the seedlings take root to obtain rooted bottle seedlings; the conditions for culturing in the culture room are light for 8 hours / Day, light intensity 1000Lux, culture temperature 22 ℃. Then carry out weak light cultivation, transfer the rooted bottle seedlings from the cultivation room to the sunshine greenhouse, and cultivate them for 30 days at a temperature of 22°C and a light intensity of 5000 Lux until the root system of the seedlings grows and the leaves turn green. piece of leaf. Then carry out strong light cultivation, and cultivate for 20 days at a temperature of 25° C. and a light intensity of 8000 Lux. When the seedlings are 7-8 cm in height and have 8-10 leaves, they can be planted out of the bottle.

Embodiment 3

[0021] Dendrobium officinale buds that have been multiplied and cultivated to a height of more than 3 cm are inoculated onto the MS rooting medium and cultivated in the culture room for 30 days until the seedlings take root to obtain rooted bottle seedlings; the conditions for culturing in the culture room are light for 8 hours / Day, light intensity 3000Lux, culture temperature 28 ℃. Then carry out low-light cultivation, transfer the rooted bottle seedlings from the cultivation room to the sunshine greenhouse, and cultivate them for 30 days at a temperature of 26°C and a light intensity of 6000 Lux until the root system of the seedlings grows, the leaves turn green, the height of the seedlings is 5 cm and the growth rate is 6-8. piece of leaf. Then carry out strong light cultivation, and cultivate for 20 days at a temperature of 26° C. and a light intensity of 12000 Lux. When the seedlings are 7-8 cm in height and have 8-10 leaves, they can be planted out of the bottle.

Abstract

The invention relates to a sunshine strong seedling method for dendrobium candidum and belongs to the technical field of the dendrobium cultivation. The method includes the steps of rooting culture, week light culture and strong light culture. The sunshine strong seedling method for dendrobium candidum has the advantages that the rooting duration of a test-tube plantlet of the dendrobium candidum is shortened by adjustment of natural light; the quality of the seedlings is greatly improved, the seedlings are strong and trim with strong roots; and after direction plant, the planting survival rate of the seedling is high and reaches over 95%, and the seedlings sprout early.

Description

technical field [0001] The invention belongs to the technical field of artificial cultivation of dendrobium, and in particular relates to a method for growing seedlings of dendrobium candidum in sunlight. Background technique [0002] The quality of Dendrobium officinale tube seedlings has a great influence on its transplanting survival rate and later growth. Therefore, test-tube seedlings are very important in the domestication of strong seedlings in the later stage. In the prior art, light cultivation is generally used, and the rooted seedlings are cultivated in the cultivation room for 3.5 to 4 months after taking root, then transplanted out of the bottle to the domestication greenhouse, and can be planted in the field through shading and hardening for about 2 months. The rate is not high, about 60%, and the growth cycle is long, and the production cost is high. Therefore, how to improve the survival rate of seedling quality and planting seedlings, shortening the growth...
