Abstract

The invention discloses study on a breeding and cultivation technology of a butterfly orchid variety and belongs to the field of crop cultivation. Through study on biological characters, stress resistance and molecular biology of good butterfly orchid varieties, a variety resource data base is built and an excellent resource core variety is constructed so that a variety resource for breeding is provided. Through distant hybridization and cell fusion biotechnologies, 5-10 cymbidium varieties and 5-10 butterfly orchid varieties are cultivated. Through the study on tissue culture and rapid propagation of the selected variety, and industrialization exploitation, more than 1000000 seedlings and more than 100000 finished potted flowers are cultivated. A cultivation technology regulation of cymbidium and butterfly orchid varieties is established.

Description

Butterfly orchid variety is cultivated and culture technique research

Technical field

Butterfly orchid variety is cultivated with culture technique research and is belonged to the crop cultivation field.

Background technology

Flowers are one of the world's ten large most active industries, and the world flower turnover was more than 3,000 hundred million dollars in 2010, and orchid has become the principal item of flowers.In China, along with deepening continuously of reform and opening-up, economic and social sustainable development, living standards of the people improve gradually, and are increasing to the demand of flowers, and flowers have become the central indispensable part of people's lives.Hybrid cymbidium, Moth orchid have all become the large annual flower of China ten, and a year consumption figure reaches about 250～3,000,000 basins.Hybrid cymbidium is spent many, Hua Yan with it, the graceful generous new lover who becomes people, and Moth orchid is graceful with its form, and the flower shape is peculiar, and the florescence is long, and is claimed " orchid queen ", and ornamental value is high.but present Moth orchid, the kind of hybrid cymbidium and culture technique are mainly some developed countries and the area is monopolized, the most of product of China relies on import, Japan, Korea S is maintaining the leading position aspect the hybrid cymbidium breeding always, China Taiwan is occupying a tiny space aspect the Moth orchid crossbreeding, become the maximum area of Moth orchid output maximum kind, the world, after 1998, Korea S, Japan, Taiwan etc. are successively in Yunnan Province of China, Guangdong, Shandong, Beijing, hybrid cymbidium and Moth orchid production base have been set up in the ground such as Shanghai, China's drug in some provinces has also been set up the production base of oneself, research and the production of culture technique aspect have been carried out, every average annual speed with 10% develops, but all production kinds are external and the area is controlled.Therefore, the research of carrying out hybrid cymbidium, Moth orchid rearing new variety and culture technique has great importance for the orchid industry production that promotes China.

Summary of the invention

[0003] 1, hybrid cymbidium, butterfly orchid variety germ plasm resource are collected the foundation with the resource garden.It is ornamental good both at home and abroad to collect, and the hybrid cymbidium of strong stress resistance, butterfly orchid variety resource are collected, and utilize tradition and modern biotechnology protect and preserve, and set up Germplasm Resources.

2, excellent strain seed selection.Intend adopting four kinds of modes: the one, crossbreeding after blooming, is determined suitable hybrid combination according to pattern, flower type, blade profile etc., selects improved seeds from filial generation; The 2nd, select good variation type from a large amount of group training seedlings; The 3rd, use pollen tube pathway and carry out gene breeding; The 4th, by monoploid hybridize-the anther culture mode cultivates good hybrid seed, obtain filial generation, and filter out improved seeds.

3, carry out the florescence control technical research.To hybrid cymbidium, Moth orchid, adopt that high mountain is brokenly slept, the artificial broken mode regulation florescence such as sleep, plant in good time.Study its Flowering mechanism and the required environmental condition of blooming, sum up a cover flower forcing technology.

4, carry out the control high-tech research of pot flowers.Appliable plant growth regulator and control rich water mode are found out feasible method and reagent combination.

5, group culturation rapid propagating technology research.The improved seeds such as hybrid cymbidium, Moth orchid are set up aseptic regenerating system, work out their propagation, subculture, root media, inquire into out the match technology means that it is cultivated from the bottle seedling to sun light green house.

6, top grade flower pot culture technology research.Comprise that matrix is selected, the selection of basin type, rich water quality management etc.Make that potted flower reaches variety pure, highly neat, the florescence is consistent, forms a complete potted flower production system.

The key technology that quasi-solution is determined: 1, the importing of gene and detection.2, the selection technology of hybrid strain.3, the exploration of the medium such as inoculation, differentiation.4, control flower and culture technique.

The invention target: (1) collects, preserves that hybrid cymbidium, Moth orchid ornamental value are high, strong adaptability, Resistant kind each more than 100.By the research to the biological race proterties of major clique, resistance and molecular biology aspect, set up the Germplasm Database of system, build the excellent resources Core Germplasms, for breeding provides germ plasm resource.(2) utilize the biotechnology engineerings such as distant hybridization, cytomixis, cultivate each 5～10 of hybrid cymbidium, butterfly orchid varieties.(3) carry out the tissue-culturing rapid propagation research of Cultivars, and carry out industrialization development, more than breeding seedling 1,000,000 strains, more than 100,000 strains of finished product potted flower.(4) make the cultivation technical specification of hybrid cymbidium, Moth orchid Cultivars.

Main innovate point

Problem characteristic: 1, germ plasm resource characteristic.Hybrid cymbidium, Moth orchid are important flower varieties, and genetic diversity is abundant, have purpose to collect and protection according to boreal climate condition characteristics, and the Germplasm Resources of setting up of target is arranged.2, the characteristic of Cultivars target.The one, sight, reach spend many, Hua Yan, the florescence is long, ornamental value is high.The 2nd, resistance preferably, Cultivars reaches the proterties such as Resistant, high temperature resistant, Salt And Alkali Tolerance.3, the fast numerous and culture technique characteristic of Cultivars.Carry out Cultivars method for quickly breeding and seedling technical research fast.Problem innovation: 1, select have degeneration-resistant, view and admire high new varieties, enrich germ plasm resource, realize the creative utilization of resource.2, the innovation of the evaluation criterion system of hybrid cymbidium, butterfly orchid variety is for breeding of new variety provides theoretical foundation.3, hybrid cymbidium, butterfly orchid variety resource genetic diversity Journal of Sex Research are for resource rational utilization and industrialization development provide foundation.

Embodiment

1, research method: the technology path that this research adopts production, teaching ﹠ research to combine, to collect hybrid cymbidium, the domestic and international improved seeds resource of Moth orchid as purpose, set up Germplasm Resources; By screening varieties, regional test carry out sight, resistance is carried out overall merit, filters out the new varieties that meet market demand; Utilize tradition and modern biotechnology to carry out breeding, cultivate new varieties degeneration-resistant, that sight is high; Supporting by Technical forms such as breeding cultivations, build breeding standardized production technical system.

2, technology path: collect fine individual plants such as domestic and international hybrid cymbidium, Moth orchid → set up each Genetic Diversity of Germplasm of Germplasm Resources → analysis → set up hybrid cymbidium, Moth orchid evaluation criterion and the index system → research that is cross-breeding → Select varieties comparative trial → regional test → new varieties and breed and study → build new quality product kind standard production technical system → new varieties with culture technique and promote and industrialization development.
