一、引言 我国农业生产的早期阶段是以黄河流域为基地的。这里的气候比较干燥,年蒸发量大于年降水量,土壤容易发生盐碱化现象。我国古代农民在长期生产实践中,很早就积累了同土壤盐碱化作斗争的经验。但是,由于历代以来对这种生产实践经验没有进行科学总结,有许多宝贵的经验或者记录不全,或者没有进行记录以致逐渐散失,是非常可惜的。现将个人在阅读古代有关文献时随时记录的一些资料,加以整理,目的是为了给从事土壤改良研究工作的同志们 I. Introduction The early stage of agricultural production in our country is based on the Yellow River Basin. The climate here is relatively dry, the annual evaporation is greater than the annual precipitation, the soil is prone to salinization. In the long-term production practice of our country’s ancient peasants, we had long accumulated experience in combating soil salinization. However, since there has been no scientific summary of this production practice experience over the ages, it is very unfortunate that many precious experiences are either incompletely documented or not recorded and gradually dissipated. At present, some individuals who keep records of relevant ancient documents have compiled them in order to give comrades engaged in soil improvement research
