Abstract: In order to study the effects of nutrient solutions supplying time on the quality of eggplant seedlings,this experiment was conducted in the intelligent greenhouse.Using eggplant heatproof cultivar ’Jing qie 6’ as the test material,we studied the effects of irrigation duration time and interval time of nutrient supplying on the quality of eggplant hole tray seedlings in the tidal irrigation seedling with central composite rotatable design with two factors.The results showed that seedling dry weight and strong seedling index along with the fluid for irrigation duration time and interval time changing tendency was consistent,the first increase after a downward trend,when eggplant grows 5 leaves and 1 heart.According to the results,we suggest that nutrition supplying shoud be conducted with the maintaining fluid of 8 to 16 minutes and with the interval time between 201 to 350 minutes for irrigation in eggplant seedling stage.
