通过对比井窖式移栽下不同覆盖物处理对烤烟大田生育期不同气候条件下田间小气候的影响,以及对不同生育时期烤烟光合特性和农艺性状的影响,探寻烤烟生长阶段的最佳覆盖物。结果表明,地膜覆盖相较于无覆盖和稻草覆盖处理,能更好地积蓄热量,起到很好的保温作用,而稻草覆盖有平抑地温、减***内温度波动的作用;覆盖栽培能增强烤烟生长关键时期的光合特性,以稻草覆盖效果最佳;覆盖栽培相较于裸栽有效提高了株高、叶数和叶面积等指标。稻草覆盖对于生长后期烟叶的伸展起到了良好的效果。综合评价,采用稻草覆盖的处理更有助于烤烟的生长发育,值得在生产上推广使用。

To explore the best mulch in the flue-cured tobacco growth stage, this paper contrasted the effects of different mulch treat- ments under well-cellar style transplanting on field microclimate of flue-cured tobacco in different climatic conditions during field growing period and on the photosynthetic and agronomic characteristics of flue-cured tobacco in different growth periods. The results showed that compared to the treatments of no mulching and straw mulching, plastic film mulching could save the heat better, playing a good role in heat preservation, while the straw mulching made a differen...
