Abstract: In order to explore the effects of peanut cake and vermicompost combined application on the yield，quality and soil characteristics of flue‑cured tobacco，and to clarify the suitable fertilization mode for improving tobacco field soil and enhancing flue‑cured tobacco yield and quality，a field experiment was conducted with 12 treatments，including 4 levels of peanut cake（0，300，600，900 kg/ha，numbered P₀，P₃₀₀，P₆₀₀，P₉₀₀）and 3 levels of vermicompost（0，500，1 000 kg/ha，numbered V₀，V₅₀₀，V₁₀₀₀）.Soil microbial quantity，enzyme activity，and nutrient content，as well as economic traits，chemical components，and appearance quality of flue‑cured tobacco were measured at the end of the curing period.The results showed that under the same amount of vermicompost，the amount of bacteria，fungi and actinomycetes in soil，the activities of invertase，urease，protease and acid phosphatase，and the contents of alkali hydrolyzable nitrogen，available phosphorus and available potassium in soil increased significantly with the application of peanut cake in the range of 0—900 kg/ha.Compared to no application of peanut cake，the application of peanut cake resulted in average significant increases of 26.0%，32.8%，and 24.7% for soil microorganisms，32.2%，75.8%，50.6%，and 69.2% for soil enzyme activities，and 17.6%，13.1%，and 19.1% for soil nutrient contents，respectively.Under the same dosage of peanut cake，the amount of bacteria，fungi and actinomycetes in soil，as well as the activities of invertase，urease，protease and acid phosphatase in soil，and the contents of alkali hydrolyzable nitrogen，available phosphorus and available potassium in soil also showed an increasing trend with the increase in vermicompost. Compared to no application of vermicompost，the application of vermicompost resulted in average significant increases of 14.9%，10.3%，and 16.9% for soil microorganisms，7.1%，14.1%，36.0%，and 39.5% for soil enzyme activities，and 7.6%，6.4%，and 6.2% for soil nutrient contents，respectively. Both peanut cake and vermicompost could improve the chemical components and appearance quality of flue‑cured tobacco and increase its yield，but the application effect was influenced by the amount of vermicompost applied. Under the condition of no vermicompost application（V₀），the average yield of flue‑cured tobacco with peanut cake application increased by 15.8% compared to no peanut cake application；under the condition of applying vermicompost（V₅₀₀，V₁₀₀₀），the average yield increase of flue‑cured tobacco with peanut cake application was 22.2% compared to no peanut cake application. In summary，the application of both peanut cake and vermicompost can increase soil microbial population，enzyme activity，and nutrient content，improve the chemical composition and appearance quality of flue‑cured tobacco，and enhance tobacco yield.The best effect is achieved by the combination of 1 000 kg/ha vermicompost and 600 kg/ha peanut cake.

摘要： 为了探讨花生饼和蚯蚓粪配施对烤烟产量、品质及土壤特性的影响，明确改良烟田土壤和提高烤烟产量、品质适宜的施肥模式，设置4个花生饼水平（0、300、600、900 kg/hm²，依次编号P₀、P₃₀₀、P₆₀₀、P₉₀₀）、3个蚯蚓粪水平（0、500、1 000 kg/hm²，依次编号V₀、V₅₀₀、V₁₀₀₀），共12个处理开展大田试验，在采收结束时测定土壤微生物数量、酶活性和养分含量，烤烟经济性状、化学成分和外观质量。结果表明，蚯蚓粪相同用量下，在花生饼用量为0~900 kg/hm²时，随着花生饼施用量增加，土壤细菌、真菌和放线菌数量，土壤蔗糖酶、脲酶、蛋白酶和酸性磷酸酶活性，土壤碱解氮、有效磷和速效钾含量显著增加，施花生饼较不施花生饼分别平均显著提高了26.0%、32.8%、24.7%，32.2%、75.8%、50.6%、69.2%，17.6%、13.1%、19.1%。花生饼相同用量下，随蚯蚓粪施用量增加，土壤细菌、真菌和放线菌数量，土壤蔗糖酶、脲酶、蛋白酶和酸性磷酸酶活性，土壤碱解氮、有效磷和速效钾含量亦呈现增加趋势，施蚯蚓粪较不施蚯蚓粪分别平均显著提高了14.9%、10.3%、16.9%，7.1%、14.1%、36.0%、39.5%，7.6%、6.4%、6.2%。施花生饼和蚯蚓粪均能改善烤烟化学成分和外观质量，提高烤烟产量，但施用效果受蚯蚓粪施用量的影响。在不施蚯蚓粪（V₀）条件下，施花生饼较不施花生饼烤烟平均增产15.8%；在施蚯蚓粪（V₅₀₀、V₁₀₀₀）条件下，施花生饼较不施花生饼烤烟平均增产为22.2%。综上，施花生饼和蚯蚓粪均能提高土壤微生物数量、酶活性和养分含量，改善烤烟化学成分和外观质量，提高烤烟产量，以蚯蚓粪1 000 kg/hm²+花生饼600 kg/hm²配施效果最佳。
