摘　　要：为了解决宁夏引黄灌区土壤盐渍化问题,提高盐土土壤质量,增强土地生产力,通过田间小区试验研究了BGA土壤调理剂对盐土油葵生长发育和土壤理化性质的影响,评价了BGA土壤调理剂的施用效果。结果表明,BGA土壤调理剂改善了盐土理化性质,较对照1降低了土壤容重,增加了土壤总孔隙度、碱解氮和有效磷含量,较对照2提高了土壤有效磷含量;BGA土壤调理剂促进了油葵生长发育,油葵株高、叶片SPAD值、光合速率提高,油葵产量较对照1提高176.7%,较对照2提高18.0%。如果降低BGA土壤调理剂的生产成本或与化肥配合施用,BGA土壤调理剂改良盐土是可行的,值得进一步研究应用。In order to solve soil salinization problem of Yellow River irrigation area of Ningxia,improve saline soil quality,and increase land productivity,the author studied the effect of BGA soil conditioner on oil sunflower growth and saline soil property,and evaluated the application effect of BGA soil conditioner through field plot experiment.The results showed that BGA soil conditioner improved physical and chemical properties of saline soil.The soil bulk density decreased while the total porosity increased,and the contents of available nitrogen and available phosphorus in soil were increased compared with CK1.The content of soil available phosphorus was also increased compared with CK2.BGA soil conditioner also promoted growth of oil sunflower.Plant height,leaf SPAD value,and photosynthetic rate of oil sunflower were improved.The yield of oil sunflower was higher 176.7% than that in CK1 and 18.0% than that in CK2.It was feasible to use BGA soil conditioner to improve saline soil if its production cost reduced or it combined with chemical fertilizers,and it was valuable to further research and develop BGA soil conditioner.
