摘　　要：以甜菜杂交种HI0936为试验材料,于2016年开展,从播种到生长发育期结束进行持续监测。设置1600-1200 Gs、1600-2400 Gs、1600-3200 Gs、1600 Gs灌水模式处理,及CK(无磁化)处理,每个处理3次重复。研究不同强度磁化水灌溉对甜菜产量增加、品质提升的影响,并结合土壤盐分、八大离子、养分的变化,旨在探索出磁化水滴灌对甜菜增产优质的最佳磁化强度。结果表明:磁化水滴灌可以加速对盐分的淋洗作用,并促进作物对土壤养分的吸收利用。磁化水滴灌有效地提升甜菜的产量,较CK提高25.1~36.9%,产糖量较CK提高27.5~39.1%。磁化处理甜菜块根的可溶性糖、蛋白质及氨基酸含量分别较CK提升了1.1~3.7%、31.9~105.6%、10.8~45.4%。研究认为磁化水滴灌可有效降低耕作层土壤盐分,提高甜菜的产量及品质,在盐渍化轻中度土壤上种植甜菜,以二次磁化1600-2400 Gs处理效果最佳。Sugar beet hybrid ＂ HI0936＂ was taken as experimental materials to probe influence of the magnetized water drip irrigation on soil salt and sugar beet yield. Experiment was carried out in 2016,and was continuously monitored from sowing to the end of the growing period. The irrigation water treatment mode was set by 1600-1200 Gs,1600-2400 Gs,1600-3200 Gs,1600 Gs,and CK（ control）; each treatment was repeated 3 times.The test is to study the effect of magnetized dripping irrigation on sugar beet growth,yield and quality and its effects on soil salinity,eight ions and soil nutrient,in order to explore the best magnetization of sugar beet yield and quality. The result shows that magnetized water irrigation accelerated the leaching of salt,and promoted the absorption and utilization of soil nutrients. Compared with the control,the production of magnetization treatment increased,and the increasing rate was 25. 1% ~ 36. 9%,the increasing rate of sugar yield was 27. 5% ~ 39.1%. Compared with the control,the content of soluble sugar,protein and amino acid of the root increased by 1.1% ~ 3. 7%,31. 9 ~ 105. 6% and 9. 6 ~ 12. 8%,respectively,after irrigating with magnetized water.These results indicated that magnetized water can effectively reduce soil salinity of the plough layer,promote the increase of sugar beet yield and improve the quality of sugar beet. It is the best for sugar beet planted in light and moderate soil,and treated with the best magnetic intensity of 1600-2400 Gs.
