复配芦苇末基质在甜椒育苗上的应用效果

Effectiveness of Mixing Reed Residue Substrate on Sweet Pepper Seedlings

以石英砂为对照,研究了以芦苇末基质为主要成分的不同配比基质在甜椒育苗上的应用效果。结果表明:50%芦苇末+25%蛭石+25%珍珠岩的混配基质理化性状较好,均在理想基质范围内,甜椒幼苗生长势良好,根系活力、叶绿素含量、净光合速率较高,育苗效果理想。

In this experiment, the effects of different mixing reed residue sediment substrates on sweet pepper seedlings culture were investigated. The results showed that the physical and chemical properties of the substrate which composed of 50% reed sediment, 25% vermiculite, 25% perlite was the most preferable. The growth state, root activity, chlorophyll content and Pn in sweet pepper seedlings were high in this proportion of substrate. It indicated that this formula of substrate was ideal for sweet pepper seedlings culture.
