摘要
目的:为了提高肥料利用率,调节烟田土壤供肥保肥能力,进而提高烤烟产质量。方法:采用田间试验,以云烟97作为供试材料,研究施用不同的肥料增效剂对烤烟土壤理化特性、烟叶钾营养、生长发育及产质量的影响。结果:施加不同的肥料增效剂,可以改善土壤理化特性,提高烟叶钾营养,从而促进烤烟生长发育,同时获得较好的产量和经济效益。结论:常规施肥+柠檬酸(54kg/hm2)处理(CA)效果最好,适宜在陕西汉中烟区推广。
A field experiment was conducted using randomized complete block design to investigate the effects of different fertilizer synergist on soil bulk density, potassium content, soil potassium, as well as the agronomic traits and economic traits of flue-cured tobacco （Yunyan97）.The results showed that applying different organic fertilizers could improve soil physical and chemical properties, increase potassium content in tobacco leaves, promote fluecured tobacco growth and get better yield and economic benefits.On the consideration of comprehensive analysis, CA is （conventional fertilization and citric acid, 54kg/hm^2） the best and suitable for promotion.
