摘　　要：针对黄河南岸灌区盐碱型中低产田高标准农田建设中地下水位高、土壤盐碱化严重、耕地质量差的问题开展耕地理化特性分析测定,进行重度盐碱地改良、土壤培肥研究,对重度盐碱地土壤与植物进行相关性分析。结果表明,通过增加土壤有效磷、有机质和全氮含量可提高重度盐碱地向日葵产量,增加土壤有效磷含量、适量增加有机质含量和全氮含量可提高重度盐碱地甜菜产量。In order to solve the problems of high groundwater level,serious soil salinization and poor cultivated land quality in the construction of high-standard farmland in saline-alkali low-and medium-yield fields in the irrigation area on the south bank of the Yellow River,the analysis and determination of the physical and chemical characteristics of cultivated land were carried out,the improvement of severe saline-alkali land and soil fertilization were studied,and the correlation analysis between soil and plants in severely saline-alkali land was carried out.Results show that surface,the yield of sunflower in heavily saline-alkali land could be increased by increasing the content of available phosphorus,organic matter and total nitrogen in the soil,the content of available phosphorus in soil,and the content of organic matter and total nitrogen could increase the yield of sugar beet in severely saline-alkali land.
