摘要：[Objectives]To optimize the fertilization technology of flue-cured tobacco Cuibi-1.[Methods]From 2015 to 2016,the experiment of spraying Saikun multi-trace element water-soluble fertilizer was carried out.[Results]7 d and 14 d after transplanting tobacco seedlings,3750 mL/ha,300 times diluted Sakun multi-trace element aqueous solution was sprayed,the growth period of Cuibi-1 in the field was extended by 3-5 d.The incidence of mosaic disease at the rosette stage and granuville wilt at the foot leaf harvesting and curing stage decreased by 4.50-20.85 kg/ha,the yield increased by 67.8-68.7 kg/ha,the proportion of high-quality tobacco increased by 1.29-3.01 percentage points,and the output value increased by 2692.5-3441 yuan/ha,the sensory smoking quality has improved.[Conclusions]Increasing the application of multiple trace elements can increase the economic benefit and industrial use value of tobacco leaf production of Cuibi-1.
