Abstract：Taking eggplant（Solanum melongena L.）cultivar‘Shenqie No.1’as experiment
material，and traditional peat and vermiculite as contrast，this study mixed corn stalk substrate with
different sizes zeolite in various rations as seedling substrates and studied the physical and chemical
properties of this substrates and its applying effect on eggplant seedling cultivation．The results showed
that adding zeolite to seedling substrate could increase the water holding porosity，and decrease in its
pH value and electrical conductivity（ EC）．When zeolite addition reached 20%-40%，the physical
and chemical properties of this substrate could meet the requirement of seedling culture and make the
emergence rate，growth vigor，and quality of eggplant seedling superior than that of the contrast. The
media（ corn stalk and zeolite ratio is 70V∶30V，zeolite in 10 mesh） could improve the quality of
eggplant seedling．Its total chlorophyll content and photosynthetic parameters of eggplant seedling leaf
were the highest，and the strong seedling index was significantly higher than those of the control and
other treatments.
