为明确垂直深旋耕改良植烟土壤和促进烤烟生长的应用效果,以传统耕作方式为对照,研究了垂直深旋耕对植烟土壤理化性状、烤烟根系和地上部分生长、干物质积累、经济性状和烟叶化学成分的影响。结果表明,（1）垂直深旋耕可提高10～40 cm耕层土壤pH 0.14～0.16,有利于提高石灰改良酸性土壤效果;（2）垂直深旋耕可降低土壤容重0.11～0.12 g/cm3,提高土壤孔隙度4.66～6.81百分点,增加土壤有机质1.5～1.93g/kg,提高烤烟大田中后期土壤氮、钾的有效性;（3）垂直深旋耕可促进烤烟根系发育,有利大田中后期烤烟地上部分生长;（4）垂直深旋耕有利于烟叶的干物质、氮、磷、钾的积累,传统耕作方式有利于烟茎的...

To clarify the effect of deep vertical rotary tillage on tobacco-planting soil improvement and its application in flue-cured tobacco production,the dynamic changes of pH and physicochemical properties of tobacco-planting soil under deep vertical rotary tillage and traditional tillage methods,as well as their effects on root growth,aboveground growth,dry matter accumulation,economic characteristics and chemical composition of flue-cured tobacco were studied.The results shoed that,(1)The deep vertical rotary tillage can increase the soil pH by 0.14-0.16 in 10~40cm plough layer,which is beneficia...
