| 摘 要： | 以常规钾肥和不施钾作对照，研究包膜控释钾肥对烤烟钾营养状况的影响。结果表明：控释钾肥可以显著提高烟叶的含钾量，施用控释钾肥75kg K2O／hm^2，150kg K2O／hm^2，225 kg K2O／hm^2的烟叶采烤后含钾量分别为2．58％，2．96％，3．01％，均达到了优质烟的标准。控释钾肥可使成熟期烟田近根区土壤速效钾出现富集，使烟叶含钾量出现升高的趋势，是能够提高烟叶含钾量的主要原因。

| Abstract: | The effects of Controlled-Release Potassium Fertilizers (CRPF) on the status in nutrition of flue-cured tobacco with employing conventional potassium fertilizer and non-potassium experiment were studied. The results indicated that the content of potassium in flue-cured tobacco leaves treated with CRPF was increased as compared to common fertilizer. The K contents of flue-cured tobacco leaves treated with 75 kg K 2O /hm 2,150 kg K 2O /hm 2,225 kg K 2O /hm 2 was 2.58%,2.96%,3.01%,respectively. The reason for the K content increases in flue-cured tobacco was that CRPF increased the content of the available potassium in the rhizosphere soil and optimized the potassium nutritional condition for growth of flue-cured tobacco. |
