摘　　要：以辣椒品种"长剑"为试材,采用3因素3水平L9(34)正交实验设计,研究了不同穴盘穴数、基质配比、施肥量对温室栽培条件下辣椒幼苗叶面积、叶绿素、根冠比、G值及壮苗指数的影响,以期为温室集约化高效育苗提供理论依据。结果表明:影响辣椒幼苗质量的主要因素是穴数,其次为基质配比,再次为施肥量。最佳组合为A1B2C2,即当穴数为72穴,基质配比为草炭∶蛭石=2∶1,复合肥施用量为2kg/m3时,辣椒幼苗的综合指标最优,健壮程度最高,幼苗质量最好。Taking the pepper variety‘Changjian＇as the test material,using 3factors and 3levels 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 was2∶1,compound fertilizer was 2kg/m3,the comprehensive index of pepper seedling was optimal,robust degree was the highest,and the quality was the best.
