Abstract

This work carried out comprehensive studies of the structure, mineralogical composition, and main indicators of silt sediment from the treatment facilities of the city of Volzhsky. Analysis of the data shows that the silt sediment is characterized by a complex mineralogical composition and has high fertilizing properties; it contains nitrogen, phosphorus, and potassium (3.30; 4.27; 0.31%, respectively), as well as organic matter (32%). Using the methods of scanning electron microscopy, IR spectroscopy, and X-ray phase analysis, the studied sludge was found to have the ability to absorb and retain water, which is an important property for fertilizers used in areas where there is no artificial irrigation. This article discusses the features of using silt sludge as a soil ameliorant in dry farming in the Volgograd region based on the example of safflower cultivation. To increase the microbiological activity of the soil, as well as the yield of dye safflower, it is recommended to apply sludge as an ameliorant at a dose of 10 t ha^–1 with the use of deep chisel tillage by the Rancho working body.

研究污泥的结构和性质以用于干旱地区农业土壤改良

摘要

这项工作对沃尔日斯基市处理设施中淤泥沉积物的结构、矿物成分和主要指标进行了综合研究。数据分析表明，淤泥沉积物的矿物成分复杂，具有很高的肥力；它含有氮、磷和钾（分别为 3.30；4.27；0.31%）以及有机物 (32%)。使用扫描电子显微镜、红外光谱和 X 射线相分析方法，研究发现所研究的污泥具有吸收和保留水分的能力，这是在没有人工灌溉的地区使用肥料的重要特性。本文以红花栽培为例，探讨了在伏尔加格勒地区旱作农业中使用淤泥作为土壤改良剂的特点。为了增加土壤的微生物活性以及染料红花的产量，建议以 10 t ha 的剂量施用污泥作为改良剂^–1使用 Rancho 工作体进行深凿耕作。
