Study On The Application Of Tree Peony In Gardens

The application of Tree Peony in Chinese Gardens was studied systematically in this paper with referring to a great deal of literature and on-the-spot investigation. The content included: the application history of tree peony in Chinese ancient traditional gardens, the characteristics and forms of application in traditional and morden gardens, the influence of traditional Tree peony's culture on its' application in gardens. The effects of light intensity on the growth and florescence of Japanese, Chinese Central plain and Chinese Northwest cultivar groups was also discussed. The results were as follows:1. In ancient time, tree peonies were often planted in flowerbeds or as single specimens in clumps or masses. As one of traditional ornamental plants, it was also planted in natural space and around the buildings which could amplify the space of landscape and make harmony between the buildings and natural scenery.2. Tree peonies were applied in modern gardens with more forms than ancient time, such as in display garden, flowerbed, perennial borders, etc. It was either planted as single specimens mixed among other plants or in clumps or masses. They were also planted in rows. Tree peony's culture may be reminded by the couplets used in gardens.3. Tree peony culture was a very important part of flower culture and it took tree peony as carrier and was syneresised the literature and arts as well as the spirits and concept of human beings. People were attracted by its' natural beauty, fond of tastes of poetry and paintings which had great influence on the application of tree peony in gardens. It all shows that Tree peony culture and its application in gardens are not only supplemented but also accelerated their development each other.4. Light was one of the necessary factors for growth and development of tree peony. The effect of light relative intensity on relative number of flowers was more obvious than that on the flower size and the length of twig. The favorable light relative intensity for cultivar groups from Central plain, Japan and Northwest was 30-75%, 27-50% and 45-100% separately.
