Problems solved by technology

[0004] At present, orchid propagation mainly adopts branching and aseptic sowing tissue culture propagation. Orchids are mostly highly heterozygous, and seed propagation often results in the separation of offspring traits, and the probability of obtaining plants with the same phenotype as the parents is low; Branches can be propagated in both seasons, but due to their slow growth, they generally need to be divided once every 2-3 years, and the propagation coefficient of ramets is low

Embodiment 1

[0022] The pseudobulbs of Cymbidium qiubeiense K.M.Feng et H.Li in good growth state were selected for cutting propagation.

[0023] 1. Pre-treatment of pseudobulbs: pseudobulbs are born on the rhizomes of orchids in clusters ( figure 1 A), separate the pseudobulb group from the plant, pinch the pseudobulb and rotate it gently, separate from the plant, do not pull it hard, and avoid damage to the pseudobulb during the operation;

[0024] 2. Cutting the pseudobulb of the mother plant: Disinfect the single-sided blade with alcohol, then wipe it clean, cut off the top 1 / 3 of the pseudobulb from top to bottom at an angle of 45°C, and keep the rhizome connected to the bottom ( figure 1 B, C);

[0025] 3. Pseudobulb wound healing treatment: the cut pseudobulb exposes the inclined surface wound, and put it at room temperature for 1h-2h, and wait for it to heal naturally;

[0026] 4. Pseudobulb placement: Evenly place the cut pseudobulbs on the garden soil mixed with orchid rhizosph...

Abstract

The invention discloses a method for promoting early germination of lateral buds of pseudobulb of orchid. The method comprises the following steps: selecting old and active pseudobulb or pseudobulb groups of orchid, obliquely cutting off the top end of the pseudobulb by using a sterile blade, placing for 1-2 hours, naturally airing, uniformly placing the pseudobulb on field soil, paving moss mixed with orchid rhizosphere soil, providing a proper temperature and humidity environment, transplanting after lateral buds of the pseudobulb germinate and grow new roots, and achieving growth of normal orchid plants under the greenhouse condition through a conventional management method. According to the method, the top end of pseudobulb of orchid is beveled, so that the pseudobulb of orchid is in a good growth environment, and the germination time of the lateral buds of the pseudobulb of orchid can be remarkably shortened.

Description

technical field [0001] The invention relates to a method for promoting early germination of orchid pseudobulb lateral buds. The invention belongs to the fields of plant cultivation technology, garden plants and ornamental gardening. Background technique [0002] Orchid (Cymbidium ssp.) is a general term for plants belonging to the monocot class Orchidaceae. Epiphytic or ground herb, with several to many leaves, usually born on the base or lower nodes of pseudobulbs, two rows, banded or rarely oblanceolate to narrowly elliptic, the base generally has a broad sheath and surrounds the pseudobulb bulbs. The orchids in the traditional Chinese famous flowers only refer to several kinds of ground orchids distributed in the genus Orchids in China, such as Chunlan, Cymbidium, Jianlan, Molan, Hanlan, Lianpetalan and Chunjian. Chinese Orchid". Chinese orchids are very different from tropical orchids with large and colorful flowers. They have no eye-catching appearance, no huge flow...
