| Magnoliaceae Michelia plants has nearly80species.It mainly distributed in tropical, subtropical and temperate regions of Asia. China has about70species, mainly in the southwest to the southeast, Yunnan have the most. Michelia tree species are evergreen trees or shrubs, tree, Hagata Kumi, Flower fragrance.When the flowers opened,it likes smile.It is the material used, pharmaceutical, oil tree precious germplasm resource, and it also the world famous landscape plants.They have optimistic development prospects. The article is based on the comprehensive research and evaluation on the plants of Magnoliaceae Michelia, and to accelerate the process of urban landscape, rich garden greening tree species. At the same time as the Magnoliaceae Michelia domesticated provides the theoretical basis, to lay a firm foundation for research. Therefore, in this paper, the basis of summarizing existing research results, ones, different period inserted skewer reproduction test, as well as the different seasons of the grafting experiment. At the same time, on21species of Michelia ecological habits, and Forestry University Campus of21species of Michelia distribution and growth were investigated. The paper draws the following conclusion:(1) Using different substrates onMalipo Michelia were rooting research, research shows that pearlite matrix on Malipo Michelia cuttingspropagation effect is best. The rooting rate that in a part of Michelia reproduction test genera, were different cutting matrix, different hormin perlite (78.13%)> perlite and river sand (1:3)(62.50%)=peat+perlite (1:3)(62.50%)> the river sand (56.25%).(2) Using different hormone concentration on Michelia chartacea for rooting, studies show that the best effect of the control of CK, the rooting ratereached78.13%.(3) On Rooting of Michelia skinneriana using different matrix, studies show that peat+perlite (1:3) matrix of Michelia skinneriana cuttingspropagation effect is the best. The rooting rate from high to low peat+perlite (1:3)(71.88%)=Perlite (71.88%)>river sand (56.25%)> perlite and sand (1:3)(43.75%). Matrix for peat+perlite(1:3), perlite rooting rate is the highest, the analysis is higher than the sand, perlite and sand (1:3) rooting rate. (4)The Michelia skinneriana rooting by different hormones, studies show that the concentration of K-IBA hormone treatment at8000mg/L, Michelia skinneriana cuttings propagation effect is the best.(5) The Magnolia stocks of Michelia were grafting propagation, the results indicate that different seasons graft survival is the biggest difference Michelia shiluensis chun, Michelia shiluensis chun graft survival rate is62%in spring, autumn graft survival rate is38%, a difference of up to24%; results show that the same season grafting Foveolata use Magnolia do grafted rootstock highest survival rate,72%in spring and autumn reaching61%.(6) Through the investigation of21species of Michelia ecological show that, Michelia species is an important species of evergreen broad-leaved forest in China. Its flower, leaves, fruits are beautiful.It also have a high ornamental value, and a certain degree of resistance and adaptation to adverse environment. They make our city more green and play an important role to maintai ecological balance. They can broaden prospects for the development of landsape plants. |
