Problems solved by technology

But at the same time, it is also found that the seedlings have a long flowering period, irregular flowering, few flowering pseudobulbs, different flowering years of the same batch of seedlings, and the flowering period of a small number of plants falls outside the natural flowering period, which makes the breeding of Dendrobium dendrobii more difficult. The cycle is extended, the ornamental value is reduced, and the cost of production management and maintenance is significantly increased, which seriously restricts the development of the dendrobium industry.

Embodiment 1

[0018] (1) Cultivation of seedlings: in October, pluck the capsules of Dendrobium dendrobii, through aseptic sowing, and cultivate strong aseptic sowing seedlings in a 7-month light culture room, place it in a greenhouse for domestication for 15 days, and then transplant In a 32-hole hole tray, the transplanted seedlings have a plant height of 6-8 cm, a stem diameter of more than 0.4 cm, and a root number of more than 8; after 20 days, the seedlings will grow new shoots and new roots; within 7 months of transplanting, they will be at the seedling stage. The size of small seedlings is 9-12cm in plant height, 2-3 pseudobulbs; the medium seedling stage is within 2 years of transplanting, and the medium seedling size is 13-18cm in plant height, about 3-5 pseudobulbs; it can be obtained after 2 years of transplanting Dendrobium dendrobium seedlings are large seedlings, the size of the large seedlings is more than 19cm in plant height, and there are more than 5 pseudobulbs.

Abstract

The invention relates to the field of plant cultivation, in particular to a flowering induction method for dendrobium nobile seedlings. The method adopts the combination of hormone induction, temperature and nutritional regulation, the problems are solved that the flowering period of the dendrobium nobile seedlings is long, and flowering is not uniform. By adopting suitable hormone concentration,spraying frequency, spraying time and reasonable low-temperature treatment temperature and time and by utilizing the C/N ratio and beneficial components of liquid-state carbon-contained compound fertilizer, the combination of nutrition regulation is conducted to induct flowering of the dendrobium nobile seedlings, multiple pseudo bulbs of dendrobium nobile can be inducted to flower, the initial flowering period is short, the quantity of flowers is large, flowering is regular, ornamental value is high, and the new method is provided for cultivation of competitive product dendrobium nobile.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a flowering induction method for spring dendrobium seedlings. Background technique [0002] Dendrobium is the general name of Orchidaceae (Orchidaceae) Dendrobium (Dendrobium Sw) plants, is a perennial epiphytic herb, is one of the four major ornamental orchids, has important ornamental value. Dendrobium can be divided into spring Dendrobium and autumn Dendrobium according to different flowering times. Generally, the natural flowering period of spring Dendrobium is from March to May. The number of flowers in a single inflorescence is 25-40, the flower volume is huge, the flower colors are rich, the flowering period is long, and it has fragrance, which is deeply loved by the public. Obtaining seedlings by aseptic sowing is an important means of breeding Dendrobium dendrobium seedlings. This method has the advantages of short production cycle, large seedling emergence and high bre...
