摘要
以玉米为对象,研究不同强度磁化水灌溉对玉米产量、品质及生长状况的影响,并结合土壤盐分和养分的变化情况,探寻磁化水玉米增产提质的最佳磁化强度。结果表明:磁化水灌溉能够有效提高土壤盐分淋洗效率,加速对盐分的淋洗作用,磁化水灌溉可有效促进玉米产量的增加及品质的提升,以1 200~2 400 Gs效果最佳。磁化水灌溉使玉米产量增加了4%~16.2%。磁化处理的可溶性糖、蛋白质及淀粉含量分别较CK提升了1.4%~38.2%、11.7%~39.6%、9.6%~12.8%。这些结果不仅表明磁化水有效地促进玉米植株的生长及产量、品质的提升,也可以作为一种技术方法大面积推广。
A field experiment was conducted to study the effects of drip irrigation with different magnetic water on soil salinity and nutrients, maize yield and quality and to determine the optimal magnetic intensity. The results showed that drip irrigation with magnetic water accelerated the elution of soil salts and improved the elution efficiency, increased maize yield by 4% 16.2%, promoted soluble sugar, protein and starch in maize ears and kernels by 1.4%-38.2%, 11.7%-39.6% and 9.6%-12.8%, respectively, compared with CK, and in which magnetic intensity of 1200-2400 Gs had the best effect. Thus, drip irrigation with magnetic water is an effective technique to be popularized in Xinjiang and similar regions.
