| 摘 要： | 目的]研究稻草覆盖还田对烤烟生长发育及品质的影响,探讨邵阳烟区稻草覆盖的最佳使用量,为进一步推广稻草覆盖、增强土壤肥力、降低烟农生产成本提供科学依据。方法]试验设5个处理:不覆盖稻草,且不覆盖地膜(T1);覆盖地膜(T2);覆盖稻草4 500kg/hm2(T3);覆盖稻草6 000 kg/hm2(T4);覆盖稻草7 500 kg/hm2(T5)。T1为对照。调查烟田的地温、土壤湿度,烟株生育期,烟叶生长发育、干物质的积累分配、经济性状、外观质量、物理特性、内在化学成分、香气物质及吸食质量。结果]稻草覆盖还田对烟田的地温和土壤湿度都有调控作用。在内在质量上,稻草覆盖还田可明显协调烟叶内在化学成分,有效地提高烟叶总糖、还原糖、氯及钾含量,降低烟叶总氮和总植物碱含量,提高烟叶类胡萝卜素和多酚含量,从而有效提高烟叶的香气品质。结论]稻草覆盖还田可有效提高烤烟品质,其中以7 500 kg/hm2覆盖量效果最佳。

| Abstract: | Objective] The aim was to study effects of rice straw returning into field on growth and development and quality of flue-cured tobacco,discuss the best amount of rice straw during rice straw returning into field,provide a scientific basis for deeply extending rice straw returning into field,enhancing soil fertility and reducing productive cost of tobacco grower.Method] Five treatments were designed,which were no covering rice straw and mulching film(T1),covering mulching film(T2) and covering rice straw 4 500,6 000,7 500 kg/hm2,respectively.And T1 was took as control(CK).The investigative flue-cured tobacco indices were earth temperature,soil humidity,growth period of plant,and growth and development,accumulation and distribution of dry matter,economic characters,exterior quality,physical properties,inner chemical compositions,physical inner fragrance and snorting quality and so on.Result] The results showed that rice straw returning into field had regulatory effects on earth temperature and soil humidity of planting tobacco field.It could also coordinate tobacco leave inner chemical compositions,effectively increase its total sugar,reducing sugar,chlorine and potassium content,decrease its total nitrogen and total plant alkaloid content,and improve its carotenoid and polyphenol content,then effectively improve its physical inner fragrance and snorting quality.Conclusion] Rice straw mulching can effectively improve the quality of flue-cured tobacco,and 7 500 kg/hm2 is the best amount of coverage. |
