采用“3415”肥料试验设计方案，对比了常宁市氮磷钾肥不同施用量及有机肥对烟草生长发育、烟叶产量和产值的影响，通过回归分析建立施肥量与烟叶产量的肥料效应方程。结果表明，烟草株高、茎围及烟叶面积随施肥量的增加而增加，其中氮主要影响株高、茎围和叶面积，磷对株高及叶面积影响较大，钾肥对茎围影响大但对叶面积影响不显著。在不施有机肥的情况下，氮肥增产率为135.20%，单位养分增产5.16 kg/kg，磷肥增产率46.96%，单位养分增产3.44 kg/kg，钾肥增产率34.58%，单位养分增产1.03 kg/kg，施用750 kg/hm2菜籽饼可增产273.1 kg/hm2，增产率48.03%。通过回归模型和经济效益分析得出，常宁市红黄泥田种植烟草N、P2O5、K2O的适宜用量为193.6、148.6和406.0 kg/hm2。
採用“3415”肥料試驗設計方案，對比瞭常寧市氮燐鉀肥不同施用量及有機肥對煙草生長髮育、煙葉產量和產值的影響，通過迴歸分析建立施肥量與煙葉產量的肥料效應方程。結果錶明，煙草株高、莖圍及煙葉麵積隨施肥量的增加而增加，其中氮主要影響株高、莖圍和葉麵積，燐對株高及葉麵積影響較大，鉀肥對莖圍影響大但對葉麵積影響不顯著。在不施有機肥的情況下，氮肥增產率為135.20%，單位養分增產5.16 kg/kg，燐肥增產率46.96%，單位養分增產3.44 kg/kg，鉀肥增產率34.58%，單位養分增產1.03 kg/kg，施用750 kg/hm2菜籽餅可增產273.1 kg/hm2，增產率48.03%。通過迴歸模型和經濟效益分析得齣，常寧市紅黃泥田種植煙草N、P2O5、K2O的適宜用量為193.6、148.6和406.0 kg/hm2。

Using 3514 fertilizer experiment design, the effects of different N, P and K fertilizer rates and organic fertilizer on growth of tobacco and yield and output value of tobacco leaves in Changning city were compared, while the fertilizer response equation between fertilizer rate and yield of tobacco leaves was established via regression analysis. The results showed that plant height, stem girth and tobacco leaf area increased with increasing fertilizer rate; among all of the fertilizers, N mainly influenced plant height, stem girth and leaf area, P had great influences on plant height and leaf area, and K influenced stem girth greatly but no obvious influences on leaf area. Without organic fertilizer, the yield-increasing rate of N was 135.20%, and per unit nutrient increased yield by 5.16 kg/kg; the yield-increasing rate of P was 46.96%, and per unit nutrient increased yield by 3.44 kg/kg; the yield-increasing rate of K was 34.58%, and per unit nutrient increased yield by 1.03 kg/kg; applying 750 kg/hm2 of rapeseed cake can increase yield by 273.1 kg/hm2 with yield-increasing rate of 48.03%. Through regression model analysis and economic benefit analysis, it indicated that the optimal fertilizer rate of N, P2O5 and K2O for planting tobacco in red-yellow mud fields in Changning city was 193.6, 148.6 and 406.0 kg/hm2, respectively.
