摘要: 土壤盐渍化程度的高低直接影响到作物的生长发育,因此,为了广辟盐渍土改良的途径,笔者在典型的盐渍化草甸土上进行了有机肥改良土壤的大区对比试验,结果表明:施用有机肥料,有机无机结合,可以促进脱盐,抑制返盐。除Ca2+外,HCO3- Cl-、SO42-、Mg2+、K+、Na+含量年平均施有机肥的均低于对照,同时施用有机肥料可以提高水稻产量15%。

Abstract: Crop growth is influencing by the degree of soil salinity. The experimental result on typical saline meadow showed that it could accelerate the effect of desalting and prohibit the uprising of salt with organic fertilizer application and the combination of organic fertilizer and inorganic fertilizer. With organic fertilizer application annually, except for HCO3-, the soil content of Cl-, SO42-, Mg2+ and Na- were lower than of control and at the same time it could increase the yield of rice by 15%.
