地膜覆盖栽培对烤烟腋芽生长的影响

Effect of the Plastic Film on Axillary Bud Development of Flue cured Tobacco

研究了地膜覆盖栽培对烤烟腋芽生长的影响。设地膜覆盖栽植后２０ｄ破膜掏苗，地膜覆盖栽植后立即破膜掏苗和不盖地膜３种处理。结果表明：地膜覆盖栽培在促进烤烟植株生长的同时，也促进了烟株腋芽的生长，尤以栽后２０ｄ破膜掏苗的为甚。另外，对地膜覆盖栽培能够促进烟株腋芽生长的原因进行了分析。

Effect of the plastic film on axillary bud development of flue cured tobacco was studied by three cultivation treatments: seedling stuck out of plastic film in the 20th day after setting seedling in soils covered by plastic film,seedling stuck out of plastic film while setting seedling in soils covering with plastic film and setting seedling in uncovered soils.The result showed that plastic film could promote axillary bud development as well as tobacco plant growth,The effect of seedling stuck out of plastic film in the 20th day after setting seedling on axillary bud development and tobacco plant growth was the most significance among three treatments.The caues of promoting axillary bud development was analysed in this paper.
