摘　　要：该文以大麦为种植品种,研究了不同异极距(2.5、2.0、1.5m)下空间电场对土壤水分和大麦生长发育的影响规律。试验结果表明:晴天施加正向空间电场可以有效地抑制大麦根系周围土壤水分的蒸发,当电压及间歇工作时间保持不变时,不同异极距下其电场强度不同,表现出的抑蒸聚水促生效果不同。空间电场异极距为2.0m时抑蒸效果最好,同时也证实了空间电场对大麦的苗鲜质量和株高的增长有良好的促进作用,与大气电场相比分别提高了26%～53%、24%～68%,且异极距为2.0m时植株的生长优势表现最为明显。该文说明适宜的正向空间电场可以抑制土壤水分的蒸发,促进植物生长。The effect of spatial electric field on soil moisture around barley root and barley growth under different pole distance（2.5,2.0,1.5 m）were studied in this paper.The results indicated that soil evaporation around barley root was restrained effectively in sunny day when the positive electric field was applied.If the field voltage and interval time are constant,the electric field intensity will be different under the different pole distances,and the effect of boosting plant growth will be different by restraining evaporation and moisture.The soil evaporation restrained effect was the best under a pole distance of 2.0 m.It also proved that spatial electric field can increase the weight of seeding and promoted the growth of barley height,which are increased by 26%-53%and 24%-68%,respectively,compared with the electric field in atmosphere,the best pole distance is 2 m for the plant growth.It shows that the appropriate positive electric field can restrain soil evaporation and promotes plant growth.
