摘要
以沈茄1号茄子为试材,传统的草炭蛭石混合基质作对照,将玉米秸秆基质与不同粒径沸石按不同比例混配形成玉米秸秆复配基质,研究其理化性质及在茄子育苗中的应用效果。结果表明,玉米秸秆基质添加沸石可增加复配基质的持水孔隙度,降低复配基质的pH值和电导率(EC),沸石添加量为20%～40%时,复配基质理化性状达到育苗要求,且茄子幼苗出苗率、长势、质量优于对照,其中玉米秸秆基质添加30%(10目)沸石时茄子幼苗的长势最好,总叶绿素含量、净光合速率最高,且壮苗指数显著高于对照及其他处理。
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.
