摘　　要：通过田间小区试验,在贵州省仁怀市和遵义市道真仡佬族苗族自治县分别研究了等养分条件下烤烟不同起垄及覆盖方式的免追肥技术对烟株生长发育和烟叶经济产量的影响。结果表明,在地膜覆盖条件下,无论是双行凹垄还是单行垄,免追肥即肥料全部基施对烤烟的主要经济指标均有促进作用。两试验点烤烟主要经济性状表现最好的均为双行凹垄全生育期地膜覆盖免追肥处理,与单行地膜覆盖有追肥的处理相比,烟叶产量增加7.7%,产值增加10.5%。The field plot experiments were carried out to study effects of flue-cured tobacco without topdressing by different ridge and cover pattern in Renhuai city and Daozhen county in Guizhou Province.The results showed that free topdressing technology could improve the major economic properties of flue-cured tobacco on the condition of covering with plastic film.The treats of double-row concave ridge without topdressing and covering with plastic film during the whole growing period was the best one in both experiments with yield and output increased by 7.7％ and 10.5％,respectively,higher than the treatment of single-row ridge with topdressing and covering with plastic film.
