Embodiment Construction

[0036] A preferred specific embodiment of the present invention is that after the stem segment of Dendrobium nobile becomes mature, the axillary buds at each node have the ability to form flower buds or tall buds, and the buds further develop to form flowers or be used for reproduction. If the environment is suitable, after germination, low temperature and drought treatment will form flower buds, and fertilizer water and high temperature promotion will form tall buds. In this process, 6-BA of appropriate concentration is assisted to increase the number of sprouts, control the time of bud development, and induce the buds to develop into flower buds or tall buds.

[0037] Such as figure 1 Shown, the method for controlling spring dendrobium flowering and reproduction mainly comprises the following steps:

[0038] Step 11. Promote the development of axillary buds:

[0039] Select a plant growth regulator that can promote the development of lateral buds of the plant, and spray it...

Abstract

The invention discloses a method which can control the blooming and the propagation of the spring dendrobium. Firstly, a plant growth regulator which is favorable for the growth of the side bud of the plant is selected, and is sprayed on the spring dendrobium plants by proper consistence and proper use method to accelerate the axillary bud to grow. When spraying the plant growth regulator, low temperature of 8-13 DEG C is matched; manure water, other circumstance condition, spray consistence and spray time are controlled, and then the axillary bud is induced to grow into a flower bud and then a flower. Or proper temperature and manure water are matched, and the sxillary bud is induced to grow into a high bud for propagation. The selected plant growth regulator is 6 benzyl aminopurine, the spray consistence is 100ppm to 500ppm; the spray method is leaf surface spray or irrigation. The invention can cause the gemma of the axillary bud of the spring dendrobium to sprout tidily, and can ensure the florescence to be unified, as well as can ensure the propagation efficiency to be high.

Description

technical field [0001] The invention relates to a method for cultivating plants, in particular to a method for controlling flowering and reproduction of potted flowers. Background technique [0002] Dendrobium dendrobium is one of the four major catalanths, and it is another new species of catalania after Phalaenopsis and Cymbidium. Spring Dendrobium is a plant of the genus Dendrobium in the family Orchidaceae, a perennial evergreen or deciduous epiphytic herb, the stem is called a pseudobulb, and the flesh is bamboo-shaped. The stem length is about 25-90cm depending on the variety, the leaves are alternate, and the racemes are 2-5. The flowers are large and showy, with a diameter of 6-10cm, and the flowering period is as long as 1-2 months. The growth of new shoots germinated from winter and spring to the end of summer and early autumn gradually stops, and terminal leaves appear. The enlarged internode axillary buds on the upper part may develop into flower buds or high ...
