摘　　要：采用丽格海棠为试验材料,分别从根系结构和根系生理指标层面研究了不同浇水频率和施肥量对丽格海棠盆花生长的影响。结果表明,基质含水量为50.00%时浇水和施用含肥20-20-20的商品肥500.00 mg.盆-1对丽格海棠的生长有较好的促进作用,根系累计连接数、根系累计长度、根系累计表面积、根系累计体积和根系生理指标等指标显著优于其他处理。The effects of different watering frequencies and fertilizer amounts on the growth of potted Begonia × elatior were studied by root morphology research and physiological index research.The results showed that,watering when the water content was 50.00% and manuring commercial fertilizer（20-20-20） 500.00 mg per pot could improve the development of B.× elatior greatly,the total root tips,length,surface area,root volume,as well as the physiological indexes of B.× elatior roots were significantly better than those of other treatments.
