摘要
用不同电导率（EC=1.2ms/cm，1．6ms／cm）和不同pH值（8．0，7．5，7．0，6．5）的营养液对栽培在1份砻糠灰＋1份珍珠岩（Ⅰ）、1份碎石＋l份细沙（Ⅱ）、1份泥炭＋1份珍珠岩（Ⅲ）及园土（CK）基质中的中国石竹（Dianthuschinensis）进行浇灌栽培，结果表明，基质Ⅲ最佳；不同EC和pH值的营养液对中国石竹栽培影响较小，但以EC=1．2ms／cm，pH=7．0略好。
Nutrient solutions of different electric conductivities (EC = 1. 2 ms/cm, 1. 6ms/cm)and pH (8. 7, 7. 5, 7. O, 6. 5 )were sprayed on Dianthus chinensis plants which were cultured in different media: ash +perlite (Ⅰ ); garnet +sand (Ⅱ ); peat +perlite (Ⅲ ) and garden soil (CK). The results showed that peat+perlite was the best medium. Different EC and pH had a little influence on soilless culture of Dianthus chinensis,but EC = 1. 2 ms/cm and pH 7. O were the perferable values.
