摘　　要：大气电场作为影响植物生长的重要环境因子已经应用到生产实践中,目前广泛使用在农业领域的空间电场防病促生机已经开始在烟草领域应用。正向空间电场环境中,漂浮在营养液面上的烟苗是接受正电荷失去负电荷的＂导电体＂,空间电场泄漏电流会由根系进入营养液,其根叶界面便会发生水分的微电解,进而根际环境中的营养液氧气浓度增加。溶氧浓度随着空间电场强度变化而变化,在液温15~17℃时,溶氧可达到3.8~5.7 mg/L,而对照组为3.6~5.3 mg/L。空间电场消失后,水体溶氧量迅速降低,45 min浓度衰减接近对照。Atmospheric electric field as an important environmental factor affecting plant growth has been applied to production practice. Space electric field preventing and promoting vitality which was widely used in agriculture field has already begun to apply into tobacco field. In the positive space electric field, tobacco seedlings floating in nutrient solution were conductor which accepted positive charge and lost negative charge. Space electric field leakage current would be from root into nutrient solution. Root leaf interface would occur moisture micro electrolysis. Oxygen concentration of rhizosphere nutrient solution was increased. Dissolved oxygen concentration changed with space electric field intensity. When liquid temperature was 15 ℃ , dissolved oxygen could reach 3.8 - 5.7 mg/L, and control group was 3.6 - 5.3 mg/L. When space electric field was disappeared, dissolved oxygen concentration reduced quickly, concentrations were close to control in 45 min.
