Through field experiments，this study is to investigate the effects of reduced fertilization on banana growth，yield，quality，soil nutrients and fertilizer utilization，and to provide technology and basis for fertilizer reduction，quality improvement and efficiency enhancement in newly-planted banana growing areas in the pearl river delta of Guangdong province.Compared with conventional fertilizer，two fertilizer managements were set up，including 26% reduction of fertilizer amount(25%，33% and 25% reduction of nitrogen，phosphorus and potassium，respectively)，and 40% reduction of fertilizer amount(50%，50% and 25% reduction of nitrogen，phosphorus and potassium，respectively)+amino acids soluble fertilizer，then their effects on the banana growth，yield，fruit quality，soil chemical characters，the nutrients uptake and accumulate in aboveground parts of banana and fertilizer utilization ratio were investigated.Compared with conventional fertilization，the banana plant height increased by 2.47% and yield increased by 16.37% after 26% reduction of total fertilizer application，but there was no significant difference in fruit quality.The contents of available phosphorus，available potassium and soil pH after 26% reduction of total fertilizer application were significantly higher than those of conventional fertilization，while the contents of alkali-hydrolyzed nitrogen and organic matter were not significantly different.And when treated with 40% reduction of total fertilizer+amino acids soluble fertilizer，the banana plant height increased by 3.98%，yield increased by 14.44%，and the fruit quality was improved with significant increase of Vc，soluble sugar and titratable acid contents.Soil quality was also greatly improved，and organic matter content increased by 9.35%.Overall，the nutrient absorption and accumulation of banana were increased using these two methods，the utilization rates of nitrogen，phosphorus and potassium fertilizer treated with 26% reduction of fertilizer amount were 8.75%，4.00% and 23.27%，respectively，while the utilization rates of nitrogen，phosphorus and potassium fertilizer treated with 40% reduction of fertilizer amount+ amino acids soluble fertilizer were 17.65%，8.53% and 33.57%，respectively.Reasonable fertilizer reduction measures can not only reduce the harm caused by excessive fertilizer input，but also promote banana production and improve soil quality.In this study，the measure of 40% reduction of fertilizer amount+amino acids soluble fertilizer is suitable for the fertilizer reduction and efficiency enhancement of newly-planted bananas in the pearl river delta.
