摘要
在微喷灌条件下研究不同水钾水平对香蕉养分吸收和产量的影响。结果表明,旱期高水高钾处理,香蕉氮、钾和钙的吸收量最高,分别为86.14、326.23、32.13 g/株,每667 m2产量最高为2781.6 kg。旱期低水条件下,低钾处理氮、磷、钾吸收量比高钾处理分别高15.44%、29.02%和6.40%,产量提高23.17%。
Effects of micro-spray irrigation coupling with water and potassium were studied on the nutrient absorption and yield of banana. The result indicated that banana of high-water and high-potassium treatment have the high yield with 2781.6 kg/667m2 and the best absorption of nitrogen, potassium and calcium, respectively with 86.14 g/plant, 326.23 g/plant and 32.13 g/plant. Under low-water condition, the low-potassium increased absorption of nitrogen, phosphorus, potassium by 15.44% ,29.02% and 6.40%, improving yield by 23.17% compared with the high-potassium.
