摘　　要：种植果蔗的经济效益较好,为了获得高产,生产上磷肥过量投入现象普遍,造成了土壤磷素大量累积、磷肥利用率较低等问题。建立基于土壤磷素营养状况和磷肥高效利用的果蔗磷肥施用技术具有实践意义。本文收集整理了我国当前果蔗磷肥施用技术的相关研究成果,并结合果蔗磷肥效益田间定位试验数据,总结了果蔗磷肥高效施用的技术方法,包括磷肥用量确定、磷肥施用时间、磷肥品种选择等等,以期降低磷肥投入的同时保证果蔗产量品质。There is a good economic return in planting chewing cane.To obtain high yield,excessive input of phosphate fertilizer is widespread,which has caused the problems of large accumulation of phosphorus(P)in soil and low use efficiency of phosphate fertilizer.Therefore,it is of practical significance to establish phosphate fertilizer application technology in chewing cane based on soil P status and high efficiency of phosphate fertilizer.In this paper,the relating research achievements on phosphate fertilizer application technology in chewing cane of China had been collected and arranged,and also our field test data of phosphate fertilizer efficiency were combined.Then we summarized the technology of efficient utilization of phosphate fertilizer on chewing cane,including the determination of phosphate dosage,the application time of phosphate fertilizer,the selection of phosphate fertilizer types and so on.It aimed to ensure the yield and quality of chewing cane while reduced the application amount of phosphate fertilizer.
