摘要： 通过大田试验研究不同新型肥料对土壤肥力及烤烟生长的影响。结果表明：液态有机中微量肥能显著提高速效钾、速效磷含量、土壤碱解氮、烤烟叶面积指数与成熟期光合有效辐射，提高烤烟物理性状、土壤有机质含量与土壤pH，促进烤烟根系生长发育；液态生物肥能显著提高烤烟的叶面积指数与土壤碱解氮含量，显著降低土壤pH，促进烤烟根系生长；固态生物肥有利于土壤有机质含量提高，但烤烟根系要劣于常规施肥；上述新型肥料均可促进烤烟生长与成熟，提高烤烟成熟期光合有效辐射，提高烤烟旺长期与成熟期的叶面积指数。

Abstract: Effects of different new type fertilizer on soil chemical properties and flue-cured tobacco growth were studied by way of field experiment.The results demonstrated that the contents of soil alkali hydrolyzable nitrogen and soil available potassium and soil available phosphorus and tobacco leaf area index and photosynthetic active radiation in maturing stages of flue-cured tobacco were increased significantly by liquid medium trace element fertilizer,physical character of flue-cured tobacco was improved, was one of the effective measures to prevent and control soil acidification,was favorable to root growth of flue-cured tobacco, the contents of soil alkali hydrolyzable nitrogen and tobacco leaf area index were increased significantly by liquid bio-fertilizer,and soil PH value
