在《中国土壤》一书中,砂姜黑土被列为潮土类,砂姜黑土亚类。而在砂姜黑土地区的土壤和农学工作者则认为砂姜黑土和潮上类土壤有明显的区别,不能列为潮土类土壤。在全国第二次土壤普查《土壤工作分类暂行方案》中又将其列为单一土类。但分歧并未解决。我们认为如果搞清了砂姜黑土的成土母质及其成土过程,砂姜黑土分类上的分歧便可水到渠成地得到解决。 江苏、安徽、山东、河南四省均有砂姜黑土分布,以安徽淮北平原分布最广,总面积约5000万亩。如果把黄潮土分布地区的近代黄泛物下边埋藏的砂姜黑土包括在内,面积将增加许多。 砂姜黑上是半水成土壤。它是在低湿排水不良的情况下,经过排水和长期耕作,使土壤脱沼泽而形成的一种古老的耕作土壤。
In the book “Soil in China”, Shajiang black soil is classified as alluvial soil and sand lime black soil. However, the soil and agronomists in the Shajiang black soil area think that there is a clear difference between shajiang black soil and tide-like soil and can not be classified as alluvial soil. In the second national soil census “classification of soil work Interim Provisions” in turn classified as a single soil class. But the differences are not resolved. We think that if we can get a clear picture of the soil parent material and the process of soil compaction, the disagreements on the classification of the Shajiang black soil can be solved in a timely manner. Jiangsu, Anhui, Shandong, Henan four provinces have sapropenetrate distribution, Anhui HuaibeiThe plains are the most widely distributed, with a total area of about 50 million mu. If you include the buried rhubarb black soil under the modern yellow pans in the distribution area of the Yellow Clay, the area will increase a lot. Sambar black is semi-hydrated soil. It is an ancient cultivated soil formed by the removal of marsh and the removal of marsh after drainage and long-term cultivation in the case of poorly drained and drained water.
