雁北地区农业综合开发公司杨培全、刘广荣、宋捷、吴田锡等,在最近完成的论文《农业生物措施改良利用盐碱地的调查报告》中,介绍了几种改良利用盐碱地的新方法。 1、电流改良据苏联莫斯科大学物理系和土壤改良系多年来对苏联不同地区盐化和碱化土的研究表明,直流电对盐碱土的改良有多方面的作用,可增加盐类的分离,加速土壤盐分的淋洗。应用1mA/cm~2直流电处理和212—260吨/公顷水量淋洗,与对照相比,土壤脱盐增加了37—57％。电流的应用,显著地改变了土壤的物理性状,细土粒
Yang Peiquan, Liu Guangrong, Song Jie, Wu Tianxi and other agricultural comprehensive development companies of Yanbei Prefecture introduced several new methods to improve the utilization of saline-alkali land in the recently completed “Report on the Investigation of Improving Biological Utilization of Agricultural and Biological Saline-alkali Land”. 1, the current improvement According to the Soviet Union Moscow State University Department of Physics and Soil Improvement Department for many years in different parts of the Soviet Union salinization and alkalization of soil studies have shown that direct current on the improvement of saline-alkali soil has many roles, can increase salt separation, acceleration Soil salt leaching. Application of 1mA / cm ~ 2 DC treatment and 212-260 tons / ha water leaching, compared with the control, soil desalination increased by 37-57%. The current application significantly changed the physical properties of the soil, fine soil
