不同类型肥料对烤烟生长的影响

Effects of Different Fertilizer Preparations on Tobacco Growth

以云烟87为供试烤烟品种、当地常规施肥为对照,在云南丽江永胜县兴营村研究了不同类型辅助肥料(高碳基土壤修复肥、沃益多减肥菌剂、花果密码生物刺激素)对烟草生长发育的影响,以筛选最适宜永胜烟区烤烟生长的烟草辅助肥料,提高烟叶品质。结果表明:团棵期、成熟期时T3处理(常规施肥+花果密码生物刺激素300~500倍液100 L/667m~2)能促进烟株生长发育,旺长期、现蕾期时T2处理(常规施肥+沃益多A液100 mL/667m~2+沃益多B液50 mL/667m~2)能促进烟株生长发育;T2处理对提高烟叶产量、烟叶化学成分积累合成、根部生长的效果最为显著;根部氮、磷含量以T3处理最高,钾含量以T2处理最高;茎秆、烟叶的氮含量以CK处理最高,磷含量以T1处理(常规施肥+高碳基土壤修复肥100 kg/667m~2)最高,钾含量以T3处理最高。

Using Yunyan 87 as the tested tobacco material,an efficacy test on different types of supplementary fertilizers(high carbon-based soil remediation fertilizer,HYT microbial inoculum,and Flower-Fruit Code biostimulant)affecting the growth and development of tobacco plants was carried out in Xingying Village,Yongsheng County,Lijiang,Yunnan to screen out the optimal one suitable for the local tobacco prodution,accordingly improving the tobacco quality.The results showed that at cluster and mature stages,T3(routine 2 fertilization+1500 L/hm of Flower-Fruit Code biostimulant 300-500 times dilution)could promote the growth and development of 22 tobacco plants,while at vigorous and budding stages,T2(routine fertilization+1500 mL/hm of HYT-A+750 mL/hm of HYT-B)could.For improving tobacco yield,chemical components accumulation and synthesis,and root growth,T2 achieved the most significant effect.T3 was the highest in nitrogen and phosphorus contents of roots,and T2 was the highest in potassium content of roots.Nitrogen content in stems and tobacco leaves was the highest in CK,phosphorus content accumulation was the highest in T1(routine fertilization+15002 kg/hm of high carbon-based soil remediation fertilizer),and potassium content accumulation was the highest in T3.
