| 摘 要： | 在高州市香蕉主产区,研究了氮、钾营养对香蕉抽蕾和产量的影响.结果表明:(1)缺氮对香蕉抽蕾、产量及效益的影响更甚于缺钾.(2)在K2O 610.5 kg/hm2基础上,随着施氮量的增加香蕉抽蕾率呈现提高的趋势.在K2O 610.5 kg/hm2基础上随着施氮量的增加,及在N 555.0 kg/hm2基础上随着施钾量的提高,香蕉产量呈现先增加后下降的规律.(3)在高州市香蕉产区,为获得第一年产蕉40 t/hm2左右的高产,适宜施肥量为N 567～630、P2O5 166～214、K2O 713～784 kg/hm2.氮、钾肥最佳配比N:K2O为1∶1.25～ 1.26. |

| Abstract: | Potassium and nitrogen are the two mostly needed nutrients by banana.A field experiment was conducted to investigate the effects of nitrogen and potassium on the bud and yield of banana in Gaozhou plantation.The results showed that:(1)Effects of nitrogen deficiency on the bud,yield and benefit of banana were worse than potassium deficiency.(2)The pumping rate of banana bud increased with the increase of nitrogen based on the K2O 610.5 kg/hm2.The yield of banana showed increasing-decreasing tendency with inc... |
