Abstract: In order to screen out the best matrix formula of annual Carpinus betulus, planting seedlings with garden soil, peat, perlite and vermiculite as matrix material, with Carpinus betulus sprout annual seedlings as test materials vermiculite, using randomized block experiment, and the design ratio of 10 kinds of substrate, in garden soil, for comparison, study on the 10 kinds of matrix formula, physical and chemical properties and Carpinus betulus seed germination characteristics, annual seedling height, ground diameter, whole plant dry matter accumulation and other growth characteristics and photosynthetic basic parameters, soluble sugar content, SOD activity, chlorophyll content, such as leaf physiological characteristics. Carpinus betulus average germination rate could reach 80%, the highest can amount to 98.44%belong to the easy germinating seeds. Different substrate treatment on Carpinus betulus seedling and growth characteristics and leaf physiological characteristics affect significantly difference (p<0.05) or extremely significant (p<0.01), among them, the fourth (garden soil, peat, vermiculite, perlite=2:1:2:3) of 0.359 g of dry matter accumulation and control significant difference;Soluble sugar content as high as 3.129%, and extremely significant difference;While dealing with four leaf SOD activity of 300 U·g-1, extremely significant difference with treatment 6, significant difference with other processing.No.4 is the best matrix formula of Carpinus betulus seedling, which provides an important theoretical basis of expanding the hornbeam in domestic culture.
