摘　　要：结合滴灌技术,分析了不同磁化强度水对土壤含水量、土壤养分及谷子生育性状的影响,探讨了不同因素对提升谷子产量的影响,并对比分析了适宜于谷子产量提升的最佳磁场强度范围。结果表明:磁化水滴灌可有效提高土壤含水量,较CK处理提高1.5%~14.4%;磁化水滴灌可加速对土壤盐分的淋洗作用,盐分降低率较CK处理高3.6%~9.3%;磁化水滴灌可有效促进谷子植株对Ca^(2+)、Mg^(2+)、K^+的吸收;磁化水滴灌可提升谷子的产量,较CK处理提高2.9%~23.9%;适宜于谷子产量提升的最佳磁场强度范围为2 400~3 600 Gs。磁化水灌溉能有效促进谷子植株的生长发育及产量提高。Magnetization water irrigation technology in agriculture has important significance for promoting crop growth and increasing crop yield. The effect of different magnetization water on foxtail millet growth and yield,and its changes on soil moisture content,soil nutrient and foxtail millet growth traits were analyzed in combination with drip irrigation techniques. also the influence of different factors on grain yield was discussed,the optimal magnetic field strength range suitable for millet yield improvement was analyzed in this paper. The results show that the magnetization treatment can effectively increase the soil moisture content,which is 1. 5% ~ 14. 4% higher than that of CK treatment; and accelerate the leaching of salt,and the increasing rate is 3.6% to 14.4%; and promote the absorption and utilization of Ca^2＋、Mg^（2＋）、K~＋ in foxtail millet; Magnetized drip irrigation can increase the yield of millet,which is 2.9% ~ 23.9% higher than that of CK treatment. and the optimal magnetic field intensity range suitable for the increase of foxtail millet yield is 2 400 ~ 3 600 Gs. Therefore,the magnetized water irrigation can effectively promote the growth and development of millet plants and yield,can be used as a technology to promote the use of a large area.
