Problems solved by technology

[0003] However, most of the hybrid orchid varieties cultivated at present are varieties selected after hybridization of Cymbidium and Jianlan and Molan, and Cymbidium is an important type of temperate ground orchids, which has excellent ornamental properties and strong fragrance, while Due to the inconsistency in flowering time with varieties such as Cymbidium, there is currently no Cymbidium hybrid orchid variety bred.

Embodiment 1

[0023] 1. The hybrid orchid 'Korean Peach Blossom' is used as the female parent and the Cymbidium is used as the male parent to carry out hybridization, and the hybrid offspring are sown aseptically;

[0024] a. Cultivation of female parent material: Select the hybrid orchid variety 'Korea Peach Blossom' as the female parent, plant mature plants that have grown for 4-5 years in the greenhouse, control vegetative growth in winter and spring, and use flowers with low nitrogen, high phosphorus and potassium Irrigate Duoduo No. 2 nutrient solution once a week, properly control the temperature in the early stage, and increase the temperature in the later stage to promote flowering in March-April;

[0025] b. Cultivation of the male parent material: select the perennial Cymbidium as the female parent, and promote Cymbidium to bloom in March-April through N, P, K nutrition, light and temperature control;

[0026] c. Hybrid pollination: quickly separate the pollen from the male parent...

Abstract

A culture method of cymbidium hybrid orchids is characterized by comprising steps of greenhouse culture and blooming regulation of parent cymbidium hybrid, hybrid orchids and cymbidium materials: a) culture of a female parent material; b) culture of a male parent material; c) hybrid pollination; d) ovary and seed development; e) sterile sowing and the like. The method is used for culturing good hybrid orchid offspring materials with characteristics of cymbidium; different from existing cymbidium hybrid and other cymbidium sinense hybrid orchids, cymbidium ensifolium hybrid orchids and the like in the aspect of morphological characteristics, growth characteristics, stress resistance and the like, the cymbidium hybrid orchids have excellent properties of the cymbidium, and the variety type of the cymbidium hybrid orchids can be enriched.

Description

technical field [0001] The invention belongs to the field of plant breeding, and in particular relates to a method for creating a hybrid orchid of the genus Orchid. Background technique [0002] Cymbidium Hybrid is a hybrid of some large-flowered epiphytic species in the Orchidaceae. Cymbidium Hybrid has a history of more than 100 years, and their parents are mainly large-flowered The tropical epiphytic orchids often have to go through repeated hybridization to form valuable varieties, and they are one of the highest-selling western orchids in the world. Although Cymbidium has bright colors, long flowering period, and high ornamental value, it is very popular among orchid lovers all over the world, but because most of Cymbidium has no fragrance, its ornamental properties can still be improved. The orchid family is rich in species, with about 68-70 species. In addition to tropical epiphytic species, there are also a large number of temperate ground species, such as Chunlan,...
