摘要
以‘NC102’为试材,在大田条件下,设置硅钙钾镁肥不同用量梯度处理(CK、T0、T750、T1125、T1500),系统取样并进行各指标测定,研究硅钙钾镁肥这种新型土壤调理剂对烟田土壤养分及烟叶品质的影响,探讨硅钙钾肥在改良酸化土壤中的作用,以期为修复土壤环境、改善烟草生长、提高烟叶质量、指导烟叶优质生产管理提供依据。试验结果表明:T1125(硅钙钾镁肥1125 kg/hm^2)处理效果最好,土壤pH值升高0.3个单位,叶片钾含量提高0.3个百分点、产值增加达4454.7元/hm^2、均价提高1.5元/kg、上等烟比例提高3.0个百分点。
With‘NC102’as the test material,different dosages(CK、T0、T750、T1125、T1500)of silicon calcium potassium magnesium fertilizer gradient treatment were set up in field to determine the agronomic indexes by systematic sampling,and investigate the effect of the new soil conditioner on soil nutrients and tobacco leaf quality and explore the fertilizer’s role in improving acidified soil.Experimental results showed that T1125(i.e.,silicon calcium potassium magnesium fertilizer 1125 kg/hm^2)got the best treatment effect,the soil pH value increased by 0.3 units,the potassium content of leaves increased by 0.3 percentage points,the output value increased by 4454.7 yuan/hm^2,the average price increased by 1.5 yuan/kg,and the proportion of fine tobacco increased by 3.0 percentage points.
