十多年来,鄂城一带滨湖低洼地区围垦了大量成片的湖田。随着围垦时间的加长,这些湖田土质有逐渐变劣的趋势。现根据我们十年来生产实践和调查,对围湖田土壤的演变情况、生产特性和改良措施提出一些看法。一、湖区的土壤形成特点和养分概况鄂城一带滨湖地区的土壤多由长江携带来的泥沙经长期淤积而成。自然植被为耐湿草本植物和芦苇。主要土壤有泥沙土、黄棕色粘质淤泥士、青泥土和烂泥土等。这些土的形成与它所处的微域地形和地下水位有密切的 For more than a decade, a large number of Hutian reclaimed land has been reclaimed in the low-lying lake area of ​​Echeng. With the lengthening of reclamation time, the quality of these lake fields will gradually deteriorate. Based on our 10 years of production practices and surveys, we present some opinions on the evolution of the soil in the Hutian area, its production characteristics and improvement measures. First, the lake formation characteristics of soil and nutrients Overview Echeng area in the lake area of ​​the soil and more by the Yangtze River sediment brought by long-term deposition. Natural vegetation is resistant to wet herbs and reeds. The main soil silt soil, yellow-brown mucilage, green soil and mud and so on. The formation of these soils is closely related to the microtopography and groundwater level in which they are located
