| 摘 要： | 为研究绿肥(豌豆)翻压后合理施用肥料问题，采用田间小区试验，在翻压绿肥的基础上通过减少 基肥用量和控释肥代替部分基肥，研究其对烟叶产量、产值和土壤肥力的影响。结果表明，绿肥翻压可 以提高低有机质土壤(有机质含量<10 g/kg)的有机质含量，对其他土壤化学性质无显著影响;绿肥翻压 后将基肥减少 15%和 30%对烟叶产量、产值无显著影响，对烟叶化学成分无明显影响。在减少 15%基肥 后，将剩余基肥的 50%以控释肥代替，可以显著提高烟叶产量和产值，提高烟叶钾含量和钾/氯比，改善 烟叶品质。

Chemical Fertilizer Reduction and Basal Application of Controlled Release Fertilizer After Green Manure Turned Down: Effects on Tobacco Yield and Quality and Soil Fertility |
| |
| Abstract: | To study the rational application of chemical fertilizer after green manure (pea, Pisum sativum) turned down, a field plot experiment was adopted to clarify the effects of basal fertilizer reduction and partially replaced by controlled-release fertilizer after green manure turned down on tobacco quality and output value and soil fertility. The results showed that green manure turned down could increase the content of organic matter in low organic matter soil (the contents of soil organic matter lower than 10 g/kg), but had no significant effect on other soil chemical properties. There was no significant effect on the yield and output value of tobacco leaves and the chemical composition of tobacco leaves when the basal chemical fertilizer was reduced by 15% and 30% after green manure turned down. After reducing the base fertilizer by 15%, replacing 50% of the remaining basal fertilizer with controlled-release fertilizer could significantly increase the yield and output value, as well as the potassium content and potassium/chlorine ratio of tobacco leaves. |
