| 摘 要： | 将硫酸镁、硫酸钾、硫酸铵施入灰泥田、潮砂田1周后,对3种肥料硫的吸附固定率,灰泥田分别为25.0%、49.0%、14.0%,潮砂田分别为8.9%、18.4%、6.9%;施过磷酸钙土壤的有效硫含量较低;过磷酸钙和硫酸钾施入土壤后,肥料硫的淋洗率为18.46%-24.45%.培养期间(105 d),土壤有机硫的矿化率为7.00%-15.07%.烟叶产值以施硫30.0 kg.hm-2处理的最高(24025.50元.hm-2);施硫量90、105 kg.hm-2处理的烟叶评吸总分较低(其中烟叶评吸的刺激性、香气量和香气质的得分较低). |

| Abstract: | By applying magnesium sulphate,potassium sulphate and ammonia sulphate to grey paddy soil and damp sandy paddy soil for 7 days,the sulphur absorption rates in grey paddy soils were respectively 25.0%,49.0% and 14.0%;the sulphur absorption rates in damp sandy paddy soil were 8.9%,18.4%,6.9%,respectively.By applying superphosphate the amount of available sulphur in soils was lower.By applying superphosphate and potassium sulphate to soils the leaching rate of sulphur was 18.46%-24.45%.During incubation period(105 days),the mineralization rate of organic sulphur in soils was 7.00%-15.07%.The output value of flue-cured tobacco leaves in the treatment of applying 30.0 kg·hm-2 sulphur was maximum(24025.50 yuan·hm-2). The total scores of evaluation of smoking flue-cured tobacco leaves in the treatments applying 90.0 and 105.0 kg·hm-2 sulphur were less,as the score of the stimulus and content of aroma and aroma quality were lower. |
