| 摘 要： | １９９８～１９９９年连续２年在南平市酸性、中等肥力的同一块水稻土上进行田间小区试验，研究科学施用石灰对烤烟农艺性状、提高烟叶产质量及降低氮素用量效果的影响。２年的试验研究结果表明，在南平烟区植烟土壤的ｐＨ４．７左右的酸性条件下，Ｋ３２６品种公顷施石灰２２５０ｋｇ，在同样的产质量效益下，公顷施用石灰可降低氮素用量３０～６０ｋｇ，磷素３６～７２ｋｇ，钾素９０～１８０ｋｇ。

| Abstract: | The experiment was carried out to investigate the effect of liming to acid soil on the agronomy properties, the quantity of the nitrogen application, the yield and quality of flue cured tobacco on the moderate fertility soil of the tobacco planting districts in Nanping of Fujian Province in 1998 1999. The results showed that under conditions of the acid soil (pH 4.7) in Nanping, same yield and quality of flue cured tobacco, using 2250 kg limestone per hectare (variety K326) could reduce the quantity of the nitrogen applications by 2 4 kg, the phosphorus 2.4 4.8 kg, the potassium 6 12 kg. |
