“渍害”,当地群众称之“暗涝”或“包浆”,是江苏省淮北花碱土地区低产的重要原因之一.关于“渍害”的研究,过去一般从“水”的角度考虑的居多,有关防治措施也不外“除涝治渍”、“开沟降渍”等水利措施.1976年我们在徐州地区睢宁县梁集公社进行土壤调查期间,发现在同样的降水和排水条件下,沙碱薄地发生“渍害”的多,曾提出过“渍害”的问题实质上是土壤肥力问题的论点.在上述认识的基础上,近几年来,我们继续进行了“渍害”防治的研究,进一步发现“渍害”形成的因素复杂,和气候、地形、土壤、水文、水文地质条件以及人为耕种活动
In the past, “waterlogging” was generally considered in the study of “stain damage”, which is one of the important reasons for the low yield in the Huaibei area of Huaibei City, Jiangsu Province. Of the prevention and control measures are nothing more than “flood control curettage”, “ditch drop” and other water conservancy measures .1976 we Xuzhou Prefecture Suining County Liangji Commune soil survey conducted during the same precipitation and drainage conditions found Under the above understanding, based on the above, in recent years, we continue to carry out a “stain damage” and many have made “stains” issue is essentially the issue of soil fertility issue.On the basis of the above understanding, The research on prevention and treatment further found that the formation of “waterlogging” was complicated by factors such as climate, topography, soil, hydrology, hydrogeology and human activities
