苏北滨海盐渍土地区,地势低平,地下水位高,矿化度大,排水深度有限,但雨量较多而较集中,有一定自然淋盐条件,因此,壤质地区的盐渍土,脱盐较容易,返盐亦很快,水盐动态变化频繁,防盐保苗困难,产量低而不稳。当地劳动人民,在长期与盐渍化作斗争的过程中,积累了极其丰富的综合改良经验,针对难于彻底排除土壤-地下水盐分影响的实际情况,重视了水盐动态的调节与控制,在建立条排沟排水系统的基础上,同时采取加强地
Subei coastal saline soil area, low lying, groundwater level is high, a large degree of salinity, drainage depth is limited, but more rainfall and more concentrated, there is a certain natural salt conditions, so loamy saline soil, Desalination easier, return salt is also very fast, frequent changes in water and salt, salt seedlings difficult, low yield and instability. The local working people have accumulated extremely rich experience of comprehensive improvement in the long-term struggle against salinization. In view of the fact that it is difficult to completely eliminate the influence of soil-groundwater salinity, attention has been paid to the regulation and control of water and salt dynamics. After establishing Drainage drainage system based on the row, while taking to strengthen
