从九十年代初以来,我们王港试验站一直从事苏北沿海滩涂盐土农业改良利用的研究工作,现将六年田间试验结果总结如下:一、重盐渍化土壤重盐渍化土壤的含盐一般在0.4%～0.8%,土壤有机质含量很低(一般都小于0.5%,)不能为农业利用,单靠雨水自然淋洗脱盐速度较慢.我们在这部分滨海盐土上采取围田蓄淡养鱼,以加速洗盐压碱和有机质积累的过程.十年试验结果,土壤盐分从平均为0.5%,下降到0.20%～0.1%左右,十年脱盐60%～80%以上,土壤有机质从0.5%提高到0.8%～1.0%,其他各种元素也有相 Since the early nineties, we have been engaged in Wanggang Experimental Station beach north of Jiangsu coastal saline soil improvement and utilization of the research work, the results of six years field trials are summarized as follows: First, heavy salinization soil salinization soil Salt is generally 0.4% ~ 0.8%, soil organic matter content is very low (generally less than 0.5%) can not be used for agriculture, water alone, natural leaching desalination slower. We are in this part of the coastal saline soil The result showed that the soil salinity decreased from 0.5% to 0.20% ~ 0.1% on an average of 10%, desalted more than 60% ~ 80% in 10 years, soil organic matter From 0.5% to 0.8% to 1.0%, other various elements also have phase
