花碱土是黄泛区各种斑状盐化浅色草甸土的总称。在我省主要分布于淮北北部地区,如肖县、碭山全境及宿县、灵璧、泗县、濉溪、毫县等县的北部。由于近几年来有些地区的农业耕作和水利措施不当,致使花碱土的面积有了发展,土壤盐碱化的程度亦有所加重。据最近统计,花碱土的面积已扩大到二百万亩左右,给当前农业生产的发展带来很大的威胁。因此,必须迅速地采取有效措施,改良利用现有盐碱地和防止次生盐碱化的继续发生。
Alkali soil is a general term for all kinds of spotted salinized light-colored meadow soil in the Yellow River. In our province are mainly distributed in the northern part of Huaibei, such as Xiao County, Dangshan and the whole county, Lingbi, Si County, Sui River, Mill County and other northern counties. Due to improper agricultural practices and water conservancy measures in some areas in recent years, the area of arkai soil has developed and the degree of soil salinization has also been aggravated. According to recent statistics, the area of alkaloid soil has been expanded to about 2 million mu, posing a great threat to the current development of agricultural production. Therefore, effective measures must be promptly taken to improve the utilization of existing saline soils and to prevent the continuation of secondary salinization.
