山东半岛北翼渤海湾内,主由黄河入海时沉积物所成的三角洲地带,占面积约四百万亩以上的荒地,即所谓“苦海盐边”的荒凉地区,抗日战争期间这里曾作过抗日根据地,因此这种荒地的开发及利用,将带动老根据地人民走向集体化生产。但本区土壤多为盐质冲积土,盐分较多,利用适当将日趋改善,否则仍可因耕作不良导致不良后果,本文就观察所得略作讨论。 Within the Bohai Bay, on the northern wing of the Shandong Peninsula, the delta formed by the sediments of the Yellow River entering the sea accounts for about 4 million mu of wasteland, the desolate area called the so-called “bitter sea salt side”. During the war of resistance against Japan, According to the base areas, the development and utilization of such wasteland will lead the people of the old base areas toward collective production. However, most of the soils in the area are alluvial saline soils with a large amount of salt, which will be gradually improved due to proper use. Otherwise, adverse consequences due to poor farming practices may still be caused. This paper briefly discusses the observations.
