| 摘 要： | 以新台糖22号甘蔗为试验材料，采用裂区设计，研究甘蔗伸长期不同配比供水量和施氮水平对甘蔗吸收矿质营养氮、磷、钾效应的影响。结果表明，伸长期每公顷施氮量360kg、每旬供水量40．0m^3（相当于每旬降雨量60mm）的高水中氮处理对甘蔗吸收氮素的效应最佳；每公顷施氮量540kg、每旬供水量40．0m^3（相当于每旬降雨量60mm）的高水高氮处理对磷素的吸收效应最佳；氮与钾1：1施用量配比的中氮处理对钾素的吸收效应最佳。

| Abstract: | Sugarcane variety ROC 22 was used as material in this experiment to study the effects of different rates of water supply and nitrogen fertilizer on absorption of mineral nutrients N,P and K at elongation stage of sugarcane.The results indicated that 360 kg/hm2 of nitrogen application and 40.0 m3/ten-day(equal to rainfall amount of 60 mm/ten-day) of water supply had the best effects on nitrogen absorption in sugarcane,540 kg/hm2 of nitrogen application and 40.0 m3/ ten-day(equal to rainfall amount of 60 mm/t... |
