Dendrobium candidum is suitable for growing in a cool, humid and ventilated environment. Born on semi-humid rocks in mountainous areas at an altitude of 1600 meters, he likes warm and humid climate and semi-cloudy and semi-sunny environment, and is not cold-resistant.
Before the tissue culture seedlings are cultivated, they should be tempered with 14~2 1 day. The specific measure is to move the tissue culture seedlings to the seedling hardening room, so that they can gradually adapt to the natural environment in an open and changeable environment, and can be planted out of the bottle when the leaves of the tissue culture seedlings are dark green.
Extended data:
The cultivation time of Dendrobium candidum is generally in spring and autumn every year, and spring is better than autumn. In Zhejiang, the best time for Dendrobium candidum cultivation is from mid-April to late June every year, during which the temperature is 12~25℃ and the air humidity is relatively high.
The survival rate of transplanted test-tube seedlings is higher and the growth time is longer after they come out of the bottle. Followed by mid-September to 10. In the meantime, it is especially necessary to do a good job in cold and antifreeze.
When planting trees, you can choose broad-leaved trees with thick bark, high water content, dense crown, herbaceous or waxy leaves and longitudinal grooves in bark (such as pueraria lobata, pear tree and camphor tree). ) as a cultivation auxiliary material; For stone planting, choose the stone with rough texture, easy moisture absorption and humus or moss attached to the surface as the planter.
When humus soil is cultivated, a high compartment with a height of 15cm is built with bricks or stones under a humid forest, humus soil, fine sand and gravel are evenly mixed and filled in the compartment, and can be planted after leveling, and a shade shed with a height of 100 ~ 120cm is built on the surface of the compartment.
