Chen Fadi; Fang Weimin; Yu Zhenxia; Yuan Cong(DePartment of Horticulture, Nanjing Agricultural University, Nanjing 21OO95 )  
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.
