摘要：

为探明不同抗旱栽培技术对烤烟的保肥保湿增温效果，通过小区试验，研究应用地膜覆盖、秸秆覆盖、地膜秸秆双覆盖、前膜后秸秆覆盖、保水剂对烤烟生长发育和烟叶品质的影响，为指导大面积烤烟生产提供依据。结果表明：地膜秸秆双覆盖、地膜覆盖，可改善烟株生长的环境条件，保湿、保肥、增温效果明显，有效降低烟株生育前期的干旱胁迫，促进烟株早长快发；秸秆覆盖和移栽时施用保水剂，随着干旱时间的延长而抗旱作用力减弱，秸秆覆盖可有效降低烟叶底烘现象的发生。

Abstract:

To clarify the effect on maintenance of fertilizer, humidity and temperature of the different cultivation techniques, the effect of five treatments of film mulch, straw mulch, film and straw mulch, straw mulch after film and water retention agent were researched. The results showed that film and straw mulch, film mulch could improve tobacco growth environmental conditions, and there were significant effect of maintenance of fertilizer, humidity and temperature. These two treatments effectively reduced drought stress in the early growth stage of tobacco, and promoted tobacco rapid growth. The role on drought resistance of the treatment of straw mulch and application of water retention agent was weakening with the drought time extension.
