“花碱土”是黄泛区各种斑状盐化浅色草甸土的总称.主要集中于淮北平原北部萧县、砀山、灵璧、泗县、宿县、濉溪、亳县等县境内;南约以灵(璧)-宿(县)-永(城)公路(即古汴堤)为界,北抵废黄河大堤,东接江苏徐准平原,西与豫东平原相邻,是本省重要的粮棉产地.由于盐碱危害,限制了农业的发展.为了适应农业发展的要求,我们曾在本区进行过以“花碱土”改良为目的的土壤调查,并在萧县黄口设站进行了定位观测.现就几年来取得的资料进行整理,本文着重对“花碱土”的类型、性态、盐分积累规律和水盐动态等作初步探讨.
“Alkaline soil” is a general term for all kinds of spotted salinized light-colored meadow soil in the Yellow River, mainly in the counties of Xiaoxian, Dangshan, Lingbi, Sixian, Suxian, Suixi and Bo county in the northern part of Huaibei Plain; About Ling (Bi) - Su (county) - Yong (city) highway (that is, the ancient embankment) as the boundary, the Yellow River embankment waste the Yellow River, east of Jiangsu Xu Zhun Plain, west and adjacent to the plains of Henan Province, is an important province Due to the damage caused by salt and alkali, limiting the development of agriculture in order to meet the requirements of agricultural development, we have conducted in the region for the purpose of the improvement of the “spent alkaline soil” soil survey, and in Xiao County Huangkou station The author made a preliminary study on the types, characters, accumulation of salt, and the dynamics of water and salt in “Cyanide” soil.
