为明确基肥中添加微生物菌剂和提苗肥中添加尿素对稻茬烤烟促早生快发的效果，以'云烟87'为材料，采用双因素试验，设计基肥中是否添加微生物菌剂2种基肥施用方法和单施烟草专用提苗肥、单施尿素、烟草专用提苗肥和尿素混施3种提苗肥施用方法，研究了微生物菌剂、提苗肥及其互作对烤烟根系、农艺性状、SPAD值、干物质积累和氮、磷、钾养分积累的影响。结果表明:基肥中添加微生物菌剂和提苗肥配施尿素较单施烟草专用追肥和基肥的根系活性、根系总长度、表面积、平均直径、体积、根尖数分别提高了28。13%、5。41%、1。30%、17。23%、24。63%，0。41%，株高、茎围、叶片数、最大叶面积分别提高了10。06%、2。30%、18。75%、37。26%，干物质、氮、磷、钾积累总量分别提高了27。18%、37。21%、36。57%、23。97%。基肥中添加微生物菌剂和提苗肥配施尿素可提高烤烟根系活性，促进烤烟根系发育，改善农艺性状，有利于烤烟干物质和氮、磷、钾养分积累，可促进烤烟早生快发，为稻作烟区'云烟87'优质丰产奠定基础。
Effects of Base Fertilizer Added Microbial Agent and Seedling-raising Fertilizer on Growth and Nutrient Accumulation of Flue-cured Tobacco
To clarify the effect of adding microbial agents in base fertilizer and urea in seedling-raising fertilizer on promoting early growth and rapid development of paddy-tobacco,'Yunyan 87'was used as material,the two-factor experiment was designed by two application methods of base fertilizer with or without adding microbial agent,and three application methods of a single application of seedling-raising fertilizer for tobacco,a single application of urea,seedling-raising fertilizer for tobacco and urea mixed application.The effects of microbial agent,seedling-raising fertilizer and their interaction on root systems,agronomic traits,SPAD value,dry matter accumulation and nitrogen,phosphorus and potassium accumulation of flue-cured tobacco were studied.The results showed that the addition of microbial agent and seedling-raising fertilizer combined with urea was better than the single application of seedling-raising fertilizer and base fertilizer,root activity,root total length,surface area,average diameter,volume and root tip number were increased by 28.13%,5.41%,1.30%,17.23%,24.63%and 0.41%,respectively.Plant height,stem girth,number of leaves and maximum leaf area were increased by 10.06%,2.30%,18.75%and 37.26%,respectively.Total dry matter,nitrogen,phosphorus and potassium accumulation were increased by 27.18%,37.21%,36.57%and 23.97%,respectively.The addition of microbial agent and seedling-raising fertilizer combined with urea in the base fertilizer could improve the root activity of flue-cured tobacco,promote the root development of flue-cured tobacco,improve agronomic properties,facilitate the accumulation of flue-cured tobacco dry matter and nitrogen,phosphorus and potassium nutrients,promote the early growth and rapid development of flue-cured tobacco,and lay a foundation for the high quality and high yield of'Yunyan 87'in tobacco-rice rotation area.
