[目的]为黑白双色地膜在烤烟生产上的应用提供理论和实践依据。[方法]以普通地膜为对照,采用黑白双色地膜覆盖烟垄,测定膜下5、10、15 cm土层中地温,并测定烤烟的生育期、农艺性状、产量、经济效益等性状,分析黑白双色地膜对烤烟生产的影响。[结果]田间覆盖双色地膜可使膜下5 cm处地温增加0.52℃,10 cm处地温增加0.38℃,15 cm处地温增加0.40℃,可缩短烟株大田生育期2 d,提高烤烟的产量和产值,具有一定的除草作用。[结论]覆盖黑白双色地膜有利于烤烟生产。

[Objective] The paper was to provide theoretical and practical basis for application of black and white film mulching on production of flue-cured tobacco.[Method] With normal film as control,black and white film was used to mulch the tobacco ridge,and the soil temperature at 5,10 and 15 cm soil layer under film was determined.Meanwhile,the growing period,agronomic traits,yield and economic benefit of flue-cured tobacco was determined,and the effect of black and white film mulching on flue-cured tobacco production was analyzed.[Result] Black and white film mulching in fields could make the soil temperature at 5 cm soil layer increased by 0.52 ℃,the soil temperature at 10 cm soil layer increased by 0.38 ℃,and the soil temperature at 15 cm soil layer increased by 0.4 ℃.It could also shorten the tobacco growing period for 2 d,and improve the yield and output value of flue-cured tobacco,with certain herbicidal effect.[Conclusion] Black and white film mulching is benefit for flue-cured tobacco production.
