为明确植烟酸化土壤施用调理剂后土壤pH值的动态变化,及其对烤烟根系特性的影响,以云南省保山市昌宁县、腾冲市的植烟酸化土壤为研究对象,采用盆栽试验,研究了石灰、木本泥炭基腐殖酸钾(腐殖酸钾)+水热法矿物钾肥(矿物钾肥)、腐殖酸钾+钙镁磷肥3种土壤调理剂组合,及硫酸钾施用对土壤pH值和烤烟根系特性的影响.结果表明:添加腐殖酸钾+矿物钾肥、腐殖酸钾+钙镁磷肥后60 d内,土壤pH值表现为先下降后逐步回升的趋势;短期内施用石灰对提高土壤pH值的效果最好,但长期来看有复酸风险.施用腐殖酸钾+矿物钾肥、腐殖酸钾+钙镁磷肥可显著(P

To clarify the dynamic variations of soil pH value and the effect on the root characteristics of flue-cured tobacco of soil conditioner application in acidified tobacco-planting soil, a pot experiment was conducted with soils of Changning County and Tengchong City, Baoshan City, Yunnan Province. The used soil conditioners consisted of lime, woody peat-based potassium humate (potassium humate for short)+hydrothermal mineral potassium fertilizer (mineral potassium fertilizer for short), potassium humate+calcium magnesium phosphate fertilizer. Also, potassium sulfate was used as one treatment bes...
