摘　　要：为研究空间电场对植物吸收CO2和生长速度的影响,首先采用同位素示踪法,分析了不同空间电场调控营养液栽培的番茄秧吸收CO2气体和HCO3-阴离子的能力,证实了14C—HCO3-是一种受控于空间电场变化的阴离子,且空间电场强度的变化方向调控着14C—HCO3-阴离子流的流动方向。在此基础上以蕹菜(空心菜)为试验材料,采取空间电场与增施CO2浓度的参数组合,做对比生长试验,通过红外线CO2分析法揭示了空间电场的极性对植物吸收CO2的速度有显著影响,且正向空间电场能显著促进植物对CO2的吸收,并得到正向空间电场与足量的CO2浓度相配合能大幅度提高温室蔬菜生长速度,使作物产量倍增的结论,为建立空间电场促进植物生长技术提供理论依据。The effects of space electric field on absorption of CO2 and growth speed of plants were studied. First,the ability of absorbing CO2 and ^14 C—HCO^-3 for tomato planted in nutrient solution under different space electric-field conditions was analyzed by isotope tracer method. It is proved that ^14 C—HCO^-3 is a kind of anion controlled by space electric field. The flow direction of ^14 C—HCO^-3 changes with space electric field strength. Taking hollow vegetable as test material, a growth-comparison test was performed by combination of the parameters of space electric field and initial concentration of CO2. The result analyzed by CO2 analytical method of infrared ray shows that polarity of electric field has remarkable influences on CO2 absorption rate of plant. The positive pole of electric field can greatly improve CO2 absorption, it can increase the growth speed and double the production of plant by a big margin in greenhouse. The research lays a foundation for further study of increasing plant growth by space electric field.
