硅肥对烤烟品种K326生长及产质量的影响

Effects of Silicon Fertilizer Application on Growth,Yield and Quality of Flue-cured Tobacco Variety K326

研究了不同硅肥施用量(0、20、40、60 kg/hm2)对临沧烟区主栽烤烟品种K326农艺性状、花叶病、产质量的影响。研究结果表明:与不施硅肥的处理相比,施用硅肥的烤烟不但提高烟叶的产量、产值、均价和烟叶的质量,而且提高了烟草的抗病性。其中施硅肥60 kg/hm2的处理在产量、产值、均价、中上等烟比例最高,分别为2 773.43 kg/hm2、48 936.23元/hm2、17.64元/kg、88.76%。

The influences of different rates of silicon fertilizer （0,20,40,60 kg/hm2） on agronomic traits, mosaic, yield and quality of flue-cured tobacco variety K326 main planted in Lincang district were studied.The results showed that ：compared with the control of non silicon fertilizer,silicon fertilizer did not only improve tobacco yield ,output value, average price,and yield and quality of tobacco,but also improve the disease resistance of tobacco.The flue-cured tobacco applied silicon fertilizer 60 kg/hm2 had the highest leaf were index.The economic indexes such as yield ,output value, average price,high and middle-class tobacco proportion are higher than any other treatments,being 2 773.43 kg/hm2,48 936.23 yuan/hm2,17.64 Yuan/kg, 88.76%.
