摘  要：
为明确邵阳烟区稻茬烤烟的种植密度和施氮量,采用偏Eta2值分析了种植密度和施氮量及其互作对烤烟经济性状的效应。结果表明:1种植密度和施氮量及其互作对不同烤烟经济性状指标的效应不一样,种植密度对烤烟上中等烟比例、均价和产值具有显著的高度影响;施氮量对烤烟均价、产量和产值具有显著的高度影响;种植密度和施氮量互作对烤烟上中等烟比例、均价、产量和产值具有显著的高度影响。2种植密度和施氮量及其互作主要影响烤烟均价。3对烤烟经济性状的影响以互作最大,占37%左右;其次是施氮量,占35%左右;种植密度最小,占28%左右。4邵阳稻茬烟区烤烟生产以种植密度16 667~18 182株/hm2、施氮量120~135 kg/hm2为好。

摘  要：
In order to explore the suitable planting density and nitrogen levels of paddy-tobacco,the effects of planting density,nitrogen levels and its interaction on economic character of flue-cured tobacco were carried out by partial Eta2 value. The results showed: 1) the effects of planting density,nitrogen levels and its interaction showed different influence on flue-cured tobacco economic characters. The effects of planting density on the fine tobacco ratio,average price and out-put value were significant higher; the effects of nitrogen levels on average price,yield and out-put value were significant higher;the interaction of planting density and nitrogen levels on the fine tobacco ratio,average price,yield and out-put value were significant higher. 2) the planting density,nitrogen levels and its interaction mainly affect average price of flue-cured tobacco. 3) the effects of interaction on economic characters of flue-cured tobacco was the maximum( about 37%); nitrogen levels was the second( about 35%) and planting density was minimum( about 28%). 4) the economic character of fluecured tobacco was good at density 16 667 ~ 18 182 plants / hm2 and nitrogen 120 ~ 135 kg / hm2 applied in paddy-tobacco area in Shaoyang.
