摘要
烤烟是需硫量较多的作物,硫素营养与烤烟的生长发育、产量、品质密切相关。研究不同硫水平对烤烟生长发育和产质量的影响。结果表明,增加硫肥的使用,能在一定程度上促进烤烟的生长,处理设计4个硫素水平S0、S1、S2、S3(每667 m2分别施硫0、2.5、5.0、7.5 kg),对烤烟株高、茎围、叶片数、最大叶面积的影响均表现为S3>S2>S1>S0,但增施硫肥对烤烟的生育期并没有产生很明显的影响。说明适量的硫肥能提高烟叶化学品质和中上等烟率,过高和过低硫肥均不利于烤烟产质量的提高。
Flue-cured tobacco is one of kinds about crop that need sulfur more than other kinds, sulfur nutrition is closely related with flue-cured tobacco growth development and yield, quality. The experiment was conducted to study the effects of sulfur application methods on the growth, leaf yield and quality of flue-cured tobacco. The results indicated that, add some sulfur fertilizer, could promote the growth of flue-cured tobacco in a certain extent, the experiment designed four sulfur fertilizer levels SO, S1, S2,S3 （0, 2.5, 5, 7.5 kg per 667m2）, flue-cured plant height, stern girth, leaf number, the biggest leaf area influence, all perform that S3〉S2〉S1〉S0. But add some sulfur fertilizer was no significant influence with the growth period of flue-cured tobacco. Proper sulfur could improve the quality of tobacco leaf chemical quality and better and average smoke rate, too high and too low sulfur fertilizer all not good for the improving of flue-cured tobacco production quality.
