引言 白浆土是三江平原的主要耕地土壤,其面积占该区总耕地面积的30％以上,早在五十年代末期,中国科学院林业土壤研究所曾昭顺先生曾对白浆土的形成进行过研究,认为白浆土与法国的淋洗土(lessivage)、德国的的假潜育土(pseudgley)、苏联的假灰土、美国的粘盘土(claypan soil)中某些土系颇为相似,并认为其形成过程是表层草甸潴育淋溶过程;以潴育为主,在潴育的基础上再发展草甸和淋溶过程,强调了由于底土粘重和季节冻层的影响而形成的临时性滞水对土壤形成的作用。1979年中国科学院南京土壤研究所徐琪先生阅读了国内外大量的关于灰化土和白浆土的材料,对白浆土形成的假说进
Introduction Albic soil is the main cultivated soil in the Sanjiang Plain. Its area accounts for more than 30% of the total cultivated area in this area. As early as the late 1950s, Zeng Zhaoshun, a researcher of the Institute of Forestry and Soil Science, Chinese Academy of Sciences, once studied the formation of albic soil. It is thought that albic soil is similar to some of the soil series in lessivage in France, pseudgley in Germany, pseudo-littoral soil in the Soviet Union and claypan soil in the United States, The formation process is surface meadows in the process of pooling and leaching; to the main pool, based on the retention and development of meadow and leaching process, emphasizing the subsoil due to sticky and seasonally frozen layer formed by the temporary Effect of stagnant water on soil formation. In 1979, Mr. Xu Qi from Nanjing Institute of Soil Science, Chinese Academy of Sciences read a large number of domestic and foreign materials on ashes and albic soils,
