摘要: 以NC102品种为试材,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(即硅钙钾镁肥1125kg/hm2)处理效果最好,土壤pH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272.78元、均价提高1.5元、上等烟比例提高3.0个百分点。

Abstract: With ‘NC102’ as the test material, different dosages (CK、T0、T750、T1125、T1500) of silicon calcium potassium magnesium fertilizer gradient treatment were set up under the condition of the field to determine the indexes with the methods of systematic sampling, which invested the effect of the new soil conditioner on soil nutrient and leaf quality in tobacco field and explored the role of silicon calcium potassium fertilizer in the improvement of acidified soil, hoping to repair the soil environment, improve the tobacco growth and tobacco quality, and guide the quality production management of tobacco. Experimental results showed that T1125 (i.e., silicon calcium potassium magnesium fertilizer 1125 kg/hm2) g6t the best treatment effect, the soil pH of which increased by 0.3 units, the potassium content of leaves increased by 0.3 percentage points, the output value increased by 4091.7 Yuan per hectare, the average price increased by 1.5 Yuan/kg, and the proportion of fine tobacco increased by 3.0 percentage points.
