摘要
初步研究了不同氮用量和种植密度对伊兹密尔品种生长状况、产量及质量的影响 .结果表明 :不同的氮用量和密度对伊兹密尔的株高、茎围、节距和叶片大小影响较大 .方差分析结果表明 ,氮用量对产量、产值的影响均达显著或极显著水平 ;但氮用量和密度互作对产量、产值影响不显著 ;氮用量和密度对均价、上等烟比例影响不显著 .综合考虑烟叶的产量、产值、均价、上等烟比例及化学成分 ,在中等肥力土壤上 ,以氮用量为 5 2 5kg·hm-2 、密度为 2 0 0万株·hm-2 处理及氮用量为 5 2 5kg·hm-2 、密度为 2 5 0万株·hm-2 处理效果较好 .
An experiment was conducted to study the effects of nitrogen rate and density on growth,yield and quality of Kukulu Izmir.The results showed that there were greater effects of nitrogen rates and density on plant height,stalk width and leaf size. The yield and output value were influenced significantly by nitrogen rates and density, were influenced insignificantly by the interaction of nitrogen rates and density.The average price and the high class leaf rate were influenced insignificantly by nitrogen rates and density.Taking into account yield,output value, average price, high class leaf rate and the chemical components,it was more suitable for oriental tobacco cultivar Kukulu Izmir that nitrogen rate was 52.5 kg per hm 2 and planting density ranged from 20×10 4 plants to 25×10 4 plants per hm 2.
