摘要/Abstract

摘要： 以玉米为研究对象，进行种子萌发试验和幼苗生长试验，研究0、1 000、3 000、5 000、8 000 Gs磁场强度磁化清水对玉米种子萌发的影响，以及磁化清水、磁化再生水对玉米幼苗生长的影响，以期为再生水的安全利用提供理论依据。结果表明，一定磁场强度（0~5 000 Gs）下，磁化清水处理玉米种子的发芽势、发芽率、发芽指数提高，活力指数降低；当磁场强度达到8 000 Gs时，发芽势、发芽率、发芽指数均有所降低，活力指数与未磁化处理一致,上述变化差异均不显著。与磁化清水相比，磁化再生水可提高玉米幼苗株高，但差异不显著；与未磁化再生水相比，磁化再生水灌溉对玉米幼苗株高前期抑制后期提高，尤其是磁场强度3 000 Gs和8 000 Gs处理。与未磁化处理相比，磁化清水、磁化再生水总体上均可提高玉米幼苗叶片含水率和SOD活性，降低土壤斥水性，中强度磁化再生水、磁化清水均会显著提高土壤盐分含量，但磁化清水、磁化再生水间差异均不显著。综合分析，磁化处理对玉米种子萌发、生长总体上有促进作用，但磁化再生水与磁化清水处理对玉米幼苗生长的影响总体上差异不显著，中强度磁化再生水、磁化清水会提高土壤盐分含量。

Abstract: Taking maize as research material,maize germination test and seedling growth experiment were carried out,the effects of magnetized clear water with five different magnetic field intensities of 0,1 000,3 000,5 000,8 000 Gs on maize germination were studied,and the effects of magnetized reclaimed water irrigation with five different magnetic field intensities of 0,1 000,3 000,5 000,8 000 Gs on maize seedling growth were also studied with magnetized clear irrigation as the control,so as to provide the theoretical basis for the safe utilization of reclaimed water.The results showed that the germination energy,germination rate and germination index of maize seeds increased with the increase of magnetic field intensity 0—5 000 Gs,and the vigor index gradually decreased,but when the magnetic field intensity reached 8 000 Gs,the germination energy,germination rate and germination index started to reduce,and the vigor index was basically the same as that of the non-magnetized treatment,but the above differences were not significant. Compared with magnetized clear water irrigation, magnetized reclaimed water irrigation could increase the height of maize seedling,but there was not significant difference. Compared with non-magnetized reclaimed water, magnetized reclaimed water could inhibit the increase of plant height to a certain extent in the early stage of maize seedlings growth,but promote the increase of plant height in the later stage of seedling growth,especially the treatments with magnetic field intensities of 3 000 Gs and 8 000 Gs. Compared with non-magnetized treatment,on the whole,magnetized reclaimed water irrigation and magnetized clear water irrigation could increase the moisture content and SOD activity of maize seedling leaves, and decrease soil water repellency; medium-intensity magnetized reclaimed water irrigation and magnetized clean water irrigation both tended to significantly increase soil salinity,but there was no significant difference between magnetized reclaimed water treatment and magnetized clean water treatment.After comprehensive analysis,magnetized water could improve maize seed germination and seedling growth on the whole, but there was no significant difference in enhancement of maize seedling growth between magnetized reclaimed water treatment and magnetized clear water treatment,and medium-intensity magnetized reclaimed water irrigation and magnetized clean water irrigation irrigation both increased soil salinity.

Key words: Reclaimed water, Magnetized water, Maize, Germination index, Seedling growth, Soil salinity
