【摘要】 试验结果表明:盐碱土壤修复材料是适宜于滨海盐渍土壤的最佳改良剂;盐碱土壤修复材料能改善土壤的物理性质,主要表现在降低土壤容重,增加土壤孔隙度,从而可以改良土壤结构,协调土壤中的水气状况,提高土壤通气性,有利于植物的生长;盐碱土壤修复材料能改善土壤的化学性质,主要表现在降低土壤含盐量和pH值,提高土壤速效N、P、K含量和土壤有机质含量,从而提高土壤肥力,保证作物生长对土壤养分的需求,为作物的生长创造适宜的土壤环境。更多还原

【Abstract】 The experimental result indicated the saline soil restoration material was the most suitable for the soil amendment.The saline soil restoration material can improve the physical property of soil,such as lowering soil bulk density and increasing porosity.The saline soil restoration material can improve the chemical property of soil obviously and reduce the content of soil salt and pH value and increase the content of rapidly available N,P,K and soil organic matter.Soil fertility was improved and soil environment became better.更多还原
