摘　　要：为了研究3种土壤改良剂的施用效果,采用多点大田试验,分析了沸石、膨润土和矿物肥土壤改良剂对烟田土壤性质和烟叶生长及质量的影响。结果表明:施用3种土壤改良剂较常规相比,能提高株高和叶面积。与常规相比,沸石、膨润土和矿物肥土壤改良剂处理的根的干物质量、叶氮素积累量、叶钾素积累量和叶硫素积累量分别显著增加19.6%~35.8%、12.1%~33.6%、22.2%~30.7%和12.8%~33.3%。施用3种土壤改良剂能显著降低土壤容重,且能够提高烟田土壤碱解氮和速效钾含量。因此,施用沸石、膨润土和矿物肥可在一定程度上改良烟田土壤,有效促进烤烟生长,显著提高烟叶产量。In order to study the application effect of three soil amendments,multi-point field experiment was conducted to analyze the effects of zeolite,bentonite and mineral fertilizer on soil properties of tobacco field,tobacco leaf growth and quality.The results showed that the application of three soil amendments could increase plant height and leaf area compared with conventional ones.Compared with the conventional treatments,the quality of root and dry matter,leaf nitrogen accumulation,leaf potassium accumulation and leaf sulfur accumulation of zeolite,bentonite and mineral fertilizer increased significantly by 19.6%~35.8%,12.1%~33.6,22.2%~30.7%and 12.8%~33.3%.The application of three soil amendments could significantly reduce the soil bulk density compared with conventional ones.Application of three soil amendments could increase the content of alkali-decomposed nitrogen and available potassium in tobacco fields.In summary,the application of zeolite,bentonite and mineral fertilizer could improve the soil to a certain extent,effectively promote the growth of flue-cured tobacco,and significantly increase the yield of tobacco leaves.
