| 摘 要： | 在微喷灌条件下研究不同水氮水平对香蕉养分吸收和产量的影响。结果表明,旱期高水高氮处理,香蕉氮、磷、钾、钙和镁的吸收量最高,分别为86.23、16.04、329.88、32.62和5.93 g/株,产量最高为34 538.4 kg/hm2。旱期低水条件下,低氮处理氮、磷、钾吸收量分别比高氮处理高4.33%、17.70%和11.03%,产量提高3.15%。

| Abstract: | Effects of micro-spray irrigation coupling with water and nitrogen were studied on the nutrient absorption and yield of banana.The result indicated that banana of high-water and high-nitrogen treatment have the high yield with 34 538.4 kg/hm2 and the best absorption of nitrogen,phosphorus,potassium,calcium and magnesium,respectively with 86.23,16.04,329.88,32.62 and 5.93 g/plant.Under low-water condition,the low-nitrogen increased absorption of nitrogen,phosphorus,potassium by 4.33%,17.70% and 11.03%,improving yield by 3.15% compared with the high-nitrogen. |
