| 【目的】提高磷肥的利用效率是解决我国南方香蕉产区土壤过量施磷的重要手段，研究原位法螯合中微量元素的磷酸一铵（MAP）与聚磷酸铵（APP）对海南香蕉生长的影响，为我国南方香蕉产区合理选用磷肥提供理论基础与数据支撑。【方法】以香蕉品种南天黄为供试作物，以 MAP、YMAP（原位法磷酸一胺）、APP、YAPP（原位法聚磷酸胺）为供试肥料，通过大田试验，研究滴灌模式下不同磷源对香蕉生长性状、养分吸收利用效率、产量及经济效益等的影响。【结果】YMAP 与 YAPP 处理比不施磷肥对照均能提高香蕉孕蕾期株高、假茎粗度、绿叶数、叶片长度和叶片宽度；YAPP、YMAP 处理对香蕉叶片速效养分含量的提高较明显，YAPP处理叶片硝态氮、速效磷、速效钾含量比 MAP 处理分别提高 35.4%、3.9%、6.9%；YMAP 处理产量较 MAP 处理增产 7.6%，YAPP 处理产量较 APP 处理增产 1.9%。【结论】原位法磷酸一胺与原位法聚磷酸胺在海南香蕉产区有良好的应用前景，尤其是原位法磷酸一胺在香蕉产量提高与经济效益方面优势明显。 |

| 【Objective】Increasing the utilization efficiency of phosphate fertilizer is an important method to solve the excessive fertilization in the soil of banana production areas in southern China. The research on in-situ MAP and APP will provide theoretical basis and data support for the reasonable selection of phosphate fertilizer in banana producing areas in southern China.【Method】The banana variety Nantianhuang was selected as test crop and MAP, YMAP, APP and YAPP were used as the test fertilizers. The field experiments were conducted to study the effect of different phosphorus on the growth characteristics, nutrient absorption and utilization efficiency, yields and economic benefits of bananas under drip irrigation modes.【Result】Compared with CK（no phosphate fertilizer）, YMAP and YAPP could increase plant height, pseudostem circumference, green leaf number, leaf length and leaf width at the bud stage; YAPP and YMAP significantly increased the available nutrient contents of banana leaves. Compared with MAP treatment, the contents of nitrate nitrogen, available phosphorus and available potassium under YAPP treatment were increased by 35.4%, 3.9% and 6.9%, respectively. The yield of YMAP increased by 7.6% compared with that of MAP treatment, and the yield of YAPP increased by 1.9% compared with that of APP treatment.【Conclusion】In-situ MAP and in-situ APP are promising fertilizer sources in Hainan banana production areas, especially, in-situ MAP has obvious advantages in terms of banana yield and economic benefits. |
