摘 要：为了考察多功能土壤调理剂（ST和MT）对酸性植烟土壤的调理效果,在田间试验条件下,以不施调理剂和当地调理措施（白云石粉）为对照,对比研究了不同调理剂对土壤pH和烤烟产质量的影响.结果表明,和不施调理剂处理相比,施用调理剂处理烤烟根系周围土壤pH提高0.5～1.5；烤烟产量和上等烟叶比例随土壤pH（4.9～6.6）的提高而增加,烟叶产量和产值分别增加4.0%～9.0%和6.0%～14.7%,上等烟叶比例提高1.5%～12.9%.和白云石粉处理相比,等量施用多功能调理剂MT处理上等烟叶比例提高11.2%,经济效益增加1 485.7元/hm2；减半施用多功能调理剂处理（白云石粉用量的50%）仍可以达到和白云石粉相当的调理效果.可见,多功能土壤调理剂具有较好的调理效果.

Abstract： Soil acidification is getting worse under long-term fertilization. In this study, a field experiment was conducted to investigate the effects of different soil conditioners on soil pH and tobacco growth in Fujian Province. No conditioner, local countermeasure （dolomite powder） were considered as controls.Multi-functional soil conditioners ST and MT were applied with halfand the same amount as dolomite powder. The results showed that compared to the treatment of no conditioner, the conditioners significantly increased rhizosphere soil pH by 0.5-1.5 units, increased the ratio of high quality tobacco leaves by 1.5%-12.9%,and significantly increased the yield and output value by 4.0%-9.0% and by 6.0%-14.7%, respectively. Compared to dolomite powder, under the same applied amount, the treatments of multi-functional soil conditionersMTsignificantly increased the ratio for high quality tobacco leaves and the economicbenefit by 11.2% and by 1485.7 Yuan/ha, respectively. Additionally, multi-functional soil conditioners applied with half amount of dolomite powder showed the equivalent conditioning effects with dolomite powder. These results suggested that the multi-functional soil conditioners havepositive effectson soil pH and tobacco growth, thus, could be recommended to be used in tobacco production.

福建省是我国烤烟种植的主要省份之一,常年种植面积保持在7万hm2左右[1].虽然烤烟生长对土壤pH适应范围较广,在pH 4.5～8.5均能正常生长和發育[2],但一般认为我国优质烤烟生产适宜的土壤pH为5.5～6.5[3].然而有研究表明福建省烟区86.6%的土壤pH小于5.5[4].较低的pH影响土壤微生物分布和活性、养分有效性,导致土壤中钾、钙、镁、钼、硼等营养元素流失,进而影响烤烟生长和烟叶品质[5-7].施用酸性土壤调理剂是改善土壤理化性状和土壤微生态环境的有效方法之一,有研究表明酸性土壤调理剂可以提高土壤pH,显著提高烟叶产量和品质[8-9].石灰、白云石粉、氢氧化镁等是最常用的酸性土壤调理剂,但长期大量施用石灰和白云石粉不仅会引起土壤板结而形成“石灰板结田”,而且容易引起土壤钙、钾、镁等元素的平衡失调而导致作物减产[10]；长期大量施用氢氧化镁所带入的镁素和钾素存在拮抗作用,影响土壤钾素有效性[11].也有学者采用氰氨化钙作为酸性土壤调理剂[12].虽然氰氨化钙调酸效果较好,而且施入土壤后产生的氰胺类物质可以抑制土传病菌生长,但大量的氰胺类物质可能会影响作物根系生长.可见,大量、单独施用上述调理剂均容易对土壤或烟株造成“二次伤害”,而在单位面积施用总量相同条件下,复合施用不同调理剂可能带来的副作用小于单独施用.此外,复合施用还可以同时提供氮、磷、镁等营养,可能具有更为显著的调理效果.为了验证该推论,选择氢氧化镁、钙镁磷、氰氨化钙、氧化钙、碳酸氢钙、风化煤等材料作为主要原料或辅料；通过合理复配,研制出多功能土壤调理剂[13],并在田间条件下研究多功能调理剂对土壤性质和烤烟生长的影响,旨在为酸性土壤改良及该多功能调理剂的推广应用提供参考.
