Abstract:
Taking the pepper variety ‘Changjian’ as the test material，using 3 factors and 3 levels orthogonal design of experiment，effects of different tray hole number，substrate ratio，amount of fertilizer on greenhouse pepper seedling leaf area，chlorophyll，root shoot ratio，G value and seedling index were studied，in order to proride theoretical basis for greenhouse intensive highefficient breeding.The results showed that the main factors affecting the quality of pepper seedling was seedling number of hole，followed by the substrate composition，again for the amount of fertilizer.The optimal combination was A1B2C2，when the seedling number of hole was 72，the ratio of peat:vermiculite substrate was 2∶1，compound fertilizer was 2 kg/m3，the comprehensive index of pepper seedling was optimal，robust degree was the highest，and the quality was the best.
