石灰窑灰是石灰煅烧过程中产生的一种细颗粒物。目前的再利用办法主要集中在水泥工业的再利用上，这一副产品固有的多孔性限制了水泥工业的再利用。由于存在钙（Ca）、镁（Mg）和可作为植物的微量营养素的其它元素，LKD具有用作常规石灰材料的替代物的潜力，用于增加土壤pHKCl和植物补充次要主要营养素（Ca和Mg）和微量营养素（Mn、Cu、Zn和Ni）。本文概述了LKD颗粒物料的理化性质及其对土壤pHKCl、土壤有效钙和有效镁含量以及春大麦秸秆和籽粒产量的影响。LKD进行了分析，使用X射线衍射，扫描电子显微镜与能量色散分析，而详细的化学分析的造粒LKD和土壤进行了原子吸收光谱法。以颗粒大小和主量元素组成作为LKD浸灰能力的主要指标。结果表明，由于释放速率高，细颗粒（0.1-2 mm）LKD可以调节低酸性土壤（pHKCl 5.4），而粗颗粒（5-8 mm）LKD不能显著增加土壤中有效钙和有效镁的含量，即使在48周后也没有达到最佳pHKCl范围。LKD最高施用量为4 t/ha时，与对照相比，春大麦籽粒产量增加，但增加不具有统计学显著性。因此，造粒石灰窑粉尘可能是一个潜在的替代天然石灰石或白云石矿物作为石灰材料的酸性土壤与颗粒大小决定石灰动力学。图形摘要
AbstractLime kiln dust (LKD) is a fine particulate material by-product produced during the lime burning processes. Current reuse options are chiefly focused on reuse in the cement industry which are limited by the inherent porosity of this by-product. Due to the presence of calcium (Ca), magnesium (Mg) and other elements which can serve as micronutrients to the plants, LKD has the potential to be used as a replacement for conventional liming materials for both soil pHKClincrease and plant supplement with secondary major- (Ca and Mg) and micronutrients (Mn, Cu, Zn and Ni). The work described here outlines the investigation of physicochemical properties of pelletized LKD materials and their effect on soil pHKCl, available Ca and Mg content in the soil as well as straw and grain yields of spring barley. LKD were analyzed using X-ray diffraction, scanning electron microscopy with energy dispersive analysis, while detailed chemical analysis of both pelletized LKD and soil was performed using Atomic Absorption Spectroscopy. Pellet size and major element composition were used as chief indicators for the liming capacity of LKD. It was shown that low acidic soil (pHKCl5.4) can be conditioned using fine (0.1–2 mm) pelletized LKD due to the high release rates while coarse pellets (5–8 mm) did not significantly increase available Ca and Mg content in soil and did not reach optimum pHKClrange even after 48 weeks. The highest application rate of LKD at 4 t/ha increased spring barley grain yield compared to control but the increase was not statistically significant. Thus, pelletized lime kiln dust could be a potential alternative to natural limestone or dolomite minerals as liming material for acid soils with the pellet size determining the liming kinetics.Graphic Abstract
