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 effects of different silicon fertilizers (0, 20, 40 and 60 kg / hm2) on agronomic characters, mosaic diseases and yield and quality of main tobacco varieties K326 in Lincang tobacco growing area were studied. The results showed that compared with the non-application of silicon fertilizers, the flue-cured tobacco with silicon fertilizer not only increased the yield, output value, average price and the quality of tobacco leaves, but also improved the disease resistance of tobacco. Among them, the treatment with 60 kg / hm2 silicon fertilizer had the highest yield, output value, average price and middle and top smoke, which were respectively 2 773.43 kg / hm2, 48 936.23 yuan / hm2, 17.64 yuan / kg and 88.76%.
