The Influences Of Different Matrixes On The Growth And Development Of Cymbidium Hybridum

Cymbidium Hybridum, which is one of the perennial herbs in Orchid Cymbidium and has been known as the world famous "Orchid Nova". It also has the Orchids colorful and Cymbidium’s fragrance and elegant, which makes it very popular in the international flower market. In recent years, it becomes one of the important high-grade potted, in that its flowering is mainly concentrated in China’s Spring Festival.Nowadays the pine bark and moss as non-renewable resource is widely used in the Orchid’s matrix, and limits the development of horticultural production from environmental and economic costs in the future. Therefore, it is the only way to develop economic and wide array sources and environmental protection type matrixes to replace the pine bark in the horticulture industry future.1. In order to choose suitable culture media, we plant Cymbidium Hybridum in eight kinds of matrix:A. pine tree bark(CK1), B. pine tree bark+moss+perlite(2:1:1,CK2), C. corncob, D. peanut hulls, E. orchid plant material, F. pine tree bark+corncob(1:1), G pine tree bark+peanut hulls(1:1), H. corncob+peanut hulls(1:1). The results analyzed show that:(1) It is affirmed initially that the corncob and peanut shells as Cymbidium Hybridum’s growing matrixes are ok, from the culture substrate solely.(2) Analysis from the plant growth index, there is no significant difference between Matrix D, E, G, and the control group. From the physiological index, there is no significant difference between Matrix E, G, and the control group. It shows that corncob can’t be used as the alternative substrates, except peanut shells. Orchid plant material not only applies to the cultivation of Cymbidium, but also applies to the orchids.In summary, the peanut shell is the best substitute matrix, combined with physical and chemical properties of matrix and growth of Cymbidium Hybridum.
