【目的】本文研究了保山烟区土壤酸化的问题。【方法】采用大田试验,选取6种土壤调理剂并以此作为改土措施,研究不同土壤调理剂对酸化植烟土壤化学性质及烤烟品质产量的影响。【结果】除钙镁磷肥外,其它土壤调理剂均能有效提高植烟土壤pH,施用石灰效果最佳,但单施石灰,易产生钙镁钾拮抗及土壤肥力下降的问题;矿物钾肥、新型增钾型生物有机肥能显著增加土壤速效钾、缓效钾、烟叶钾含量,实现增钾提质;0 ~ 15 cm耕层土壤矿物钾肥(水热法)速效钾、缓效钾含量分别极显著高于石灰处理62.13 %、33.97 %,15 ~ 30 cm耕层土壤矿物钾肥(煅烧法)速效钾、缓效钾含量分别极显著高于石灰82.59 %、24.01 %;土壤调...

【Objective】In this paper,the problem of acidifying soil in Baoshan tobacco-growing area was studied.【Method】Six kinds of soil conditioner were selected as soil remediation measures to study the effects of different soil conditioner on the chemical properties of acid soil and the quality and yield of flue-cured tobacco.【Result】In addition to calcium magnesium phosphate fertilizer,the other soil conditioners could improve the soil p H,of which lime was the best,however,application lime was alone,it was easy to produce calcium magnesium pota...
