Southern Anhui Province, peony cultivation history and the South introduction and cultivation Peony theory analysis shows that the southern Anhui Province, has a long history of peony cultivation introduction, with the southern peony cultivation and breeding base in good condition. Central Plains peony varieties through a step-by-step introduction and domestication in southern Anhui Province, such as the transitional introduction of Chaohu, to achieve in the south is feasible. In this thesis through the ecological adaptability of Chaohu City, the introduction of the 23 varieties of peony judgment and evaluation, to provide reference for future introduction in the south peony. Research methods by comparing the different varieties of peony in the introduction and in situ plant type, flower, state flowers, flowering, flower size of rate of flowers, growth potential, disease resistance difference. The cultivation experiment show that the performance of different varieties of peony quite different. Asked to select suitable for the the Chaohu introduction and cultivation of peony varieties depending on Introduction. 23 varieties, Ling Hua Zhan Lu, Sheng Dan furnace, the Oolong holding Sheng, the purplish blue Quebec, Yan Zi Ying Hui Ying Luo Sarah, 9 Central Plains of the the Bunning purple, and the great, fat red peony varieties and varieties of peony Kao adapt better. Emphasis on viewing needs, it may be appropriate to reduce the standard of peony adapt to the climate, choose varieties of ornamental value, such as the first case of red, purple Court, purple blooming. Some do not adapt to the peony varieties, according to the special viewing needs, the introduction of a small amount of cultivation, such as the Central Plains of the Yellow peony varieties Yao Huang. Jinyu cross chapter, delphinium red equipment, Qinglong Town, Bao three varieties of peony growing and disease resistance in high temperature and high humidity season is weak, in the Introduction, to be taken seriously. The results of this study has important reference value to the South introduction and cultivation Peony. Further to consider the purpose of the Southern introduction and breeding of heat-resistant varieties of peony, peony varieties of Chaohu introduction and cultivation of the Central Plains, the priority should be given to flower high in the country of origin, strong growth potential varieties, while supplemented resist glare high temperature and humidity adversity supporting technical measures. This selection criteria Southern introduction and cultivation of peony has important practical significance. Japanese peony varieties in Chaohu flowering late in the Central Plains peony varieties, resistant to hot and humid climate, suitable in the southern region of China to further promote the introduction. The paper also studied under high temperature and humidity of the South delphinium red equipment, powder E Johnson, Oolong holding Sheng, fat red peony varieties the Xia Jiguang together diurnal variation, draw the following conclusions: photosynthetic rate, transpiration rate, stomatal conductance degrees and other physiological factors of the corresponding stress response. Four varieties of peony diurnal variation of net photosynthetic rate was not obvious form of a bimodal curve; transpiration rate changes show some irregularities; stomatal conductance showing a single curve, with the enhancement of light, temperature increases , has been a downward trend after 9:00 four varieties of peony stomatal conductance showed. Net photosynthetic rate and photosynthetic impact factor between multiple regression equation is established, the importance of the impact factor sorted according to the partial correlation coefficient greater impact factor is light and high temperature conditions Peony photosynthetic rate stomatal conductance and intercellular CO2 concentration. Therefore, under high temperature conditions in the summer strong light partial shade against Peony Mulching with Straw, evening spray can, to some extent, mitigate the adverse effects of light and high temperature of tree peony. In Chaohu, hot and humid weather in the summer May Peony growth stress effects. May and June Peony noon shading treatments. Peony full day shading treatments in July and August. Light long-term high temperature and humidity stress conditions, peony performance irreversibly leaves victims, reduced chlorophyll content, photosynthetic rate decreased. The Peony leaf symptoms of heat injury severity, chlorophyll content, photosynthetic rate of change in conditions to help you distinguish between the different varieties of peony resistance to the strength of the hot and humid ability. Follow the principles of ecology and aesthetics, combined with the local culture of the peony, with reference to the different varieties of peony group ecological characteristics, ornamental characteristics and the overall landscape needs, the rational allocation of peony cultivars in the Southern landscape. The long term, Introduction, cultivation in the south Peony through a step-by-step introduction south, combined with measures to cultivation techniques; established in Chaohu, Tongling, Ningguo Peony introduction and domestication breeding base, breeding methods such as heat resistance varieties to progressive realization.
