摘　　要：通过大田调查和盆栽试验,研究了不同前茬作物玉米和甘薯对烟草生长的影响。结果表明:玉米比甘薯吸收较多的氮和磷元素,但吸收氯的能力比甘薯低;土壤施用玉米面和甘薯面能显著促进烟草的生长发育,显著提高烟草品质,以施用量为50 g/盆的烟草综合表现最好;甘薯茬更适合种烟草。Effects of different fore- rotating crops, corn and sweet potato, on tobacco growth and quality were studied through field and pot experiments. The results showed that maize absorbed more nitrogen and phosphorus and less chlorine than sweet potato did. Appling maize or sweet potato flour in pot soil could remarkably promote the growth and improve the quality of tobacco. The optimal dosage is 50g/pot. Generally, sweet potato as fore- rotating crop is better than maize.
