The branches and leaves of orchids are long, dark green and brightly colored. They have a high ornamental value. Potted plants can decorate the environment and arrange various commercial spaces. They can also be used in conjunction with other flowers to build all kinds of flower beds. After the flower branches are cut, the vases are bottled with water. It can be maintained for several weeks and is a high-grade flower arrangement material. In order to understand the influence of the plant growth environment, the effects of light and temperature on the growth and flowering time of wild Chunlan and Cymbidium were studied under light and temperature conditions.
Xiaolongshan Forest Region is located in the transitional zone between the southern edge of the warm temperate zone and the northern subtropical zone. The natural conditions are superior, the climate is humid, species are abundant, and wild orchid resources are abundant, especially the wild Chunlan and Cymbidium are widely distributed in the forest. Two kinds of wild orchids were placed in four greenhouse light incubators with temperatures of 8, 12, 16, and 20°C respectively, and 10 pots of each species in greenhouses of different temperatures were placed in natural light and shading (50% shading). Under the conditions of the shading net), spray water twice a day to maintain the appropriate humidity. Observed records in the plant flower bud growth, flowering time and flowering period.
The growth of the two wild orchids showed an increasing trend both before and after flowering, which was greater after flowering. Before flowering at 12°C, Chunlan treatment had some significant differences between 12°C and 16°C. From the observation of the growing habit of wild orchids in the light incubator, it can be known that the flowering time in Xiaolongshan forest area is about 4-5 months, and the average temperature in this period is 11-18°C.
Illumination is indeed also a very important environmental factor for the growth of plants. Before and after flowering, the light intensity of the light incubator exhibited an increase in the wild orchids, whereas the increase in the influence of the hazel orchid was significantly greater than that of the shaded part after flowering, but the growth rate and influence of both were different in the light incubator. There is no obvious difference between them.
