Description
Technical field
The present invention relates to field of plant cultivation, the flower induction method of specifically a kind of nobile-type dendrobium seedling.
Background technique
Dendrobium is the general name of orchid family (Orchidaceae) Dendrobium (Dendrobium Sw) plant, belongs to perennial and grows nonparasitically upon another plant
Herbaceous plant is one of four cattleyas ornamental greatly, has important ornamental value.Dendrobium can divide according to the difference of flowering time
For nobile-type dendrobium and autumn dendrobium nobile, the general nobile-type dendrobium natural florescence, inflorescence was extracted out by middle and upper part internode or top axil in 3~May,
Each pseudobulb is bloomed 10~25, the single inflorescence flower number of some types 25~40, and greatly, pattern is abundant for flower amount, the florescence
It is long, and there is fragrance, it is deeply loved by the public.The important hand that seedling is nobile-type dendrobium seedling breeding is obtained by aseptic seeding
Section, this method have it is with short production cycle, output of seedling is big, breed the advantages that high-efficient, to production and breeding research have important meaning
Justice.Inventor has carried out nobile-type dendrobium artificial breeding by aseptic seeding, and seed is sprouted and seedling cultivation all achieves success, part
Seedling has been bloomed.But a year limit for length it has also been found that seedling is bloomed simultaneously, blooms irregular, and pseudobulb of blossoming is on the low side, with batch seed
Seedling blooms that the time limit used is different and the florescence of fraction plant falls in problem outside the nature florescence, so that nobile-type dendrobium is educated
Kind cycle stretch-out, ornamental value reduce, and production is managed and protected cost and significantly improved, and seriously constrain the development of dendrobium industry.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of flower induction side of nobile-type dendrobium seedling
Method, the method combined using hormone induction, temperature and nutrition regulation are solved nobile-type dendrobium seedling and bloomed a year limit for length, bloomed not
The problems mentioned above in the background art such as consistent.
To achieve the above object, the invention provides the following technical scheme:
A kind of flower induction method of nobile-type dendrobium seedling, comprising the following steps:
(1) seedling breeding: October picks nobile-type dendrobium capsule, by aseptic seeding, cultivates through 7 Ge Yue illumination culturing room
