Abstract

The application of organic fertilizer can effectively alleviate soil hardening and reduce environmental pollution, which is very important for the sustainable development of agriculture (Dong et al., 2010). With the development of ecological agriculture, the challenge of agricultural non-point source pollution control has resulted in the more widespread application of commercial organic fertilizer (Jiang et al., 2018). Commercial organic fertilizer is different from other fertilizers in terms of friction and flow characteristics due to the differences in moisture and chemical composition (Huang et al., 2017), while the existing feeders for commercial organic fertilizer produce a poor performance. In the process of fertilization, the discrete element method (DEM) has been widely used to study the interaction of typical bulk materials like soil, seed and fertilizer with agricultural equipment, as well as the relevant movement states (Huang et al., 2016; Liu et al., 2018; Hu et al., 2016; Molenda et al., 2011). In a discrete element simulation analysis, the accuracy of the parameters for the particle material model is the key to the reliability of the simulation (Zhong et al., 2009; Han et al., 2014; Gallego et al., 2020). However, the parameters for contact between materials in © 2021 Institute of Agrophysics, Polish Academy of Sciences

商品有机肥离散元模拟模型的参数标定

施用有机肥可以有效缓解土壤板结，减少环境污染，这对农业的可持续发展非常重要（Dong et al.，2010）。随着生态农业的发展，农业面源污染控制的挑战导致商业有机肥的应用更加广泛（Jiang et al.，2018）。由于水分和化学成分的差异，商业有机肥料在摩擦和流动特性方面与其他肥料不同（Huang et al.，2017），而现有的商业有机肥料进料器性能较差。在施肥过程中，离散元法（DEM）已被广泛用于研究土壤、种子、肥料等典型大宗物质与农业设备的相互作用以及相关运动状态（Huang et al.，2016；刘等人，2018；胡等人，2016；Molenda等人，2011）。在离散元模拟分析中，颗粒材料模型参数的准确性是模拟可靠性的关键（Zhong et al.，2009；Han et al.，2014；Gallego et al.，2020）。然而，©2021波兰科学院土壤物理研究所中材料之间接触的参数

期刊介绍： The journal is focused on the soil-plant-atmosphere system. The journal publishes original research and review papers on any subject regarding soil, plant and atmosphere and the interface in between. Manuscripts on postharvest processing and quality of crops are also welcomed. Particularly the journal is focused on the following areas: implications of agricultural land use, soil management and climate change on production of biomass and renewable energy, soil structure, cycling of carbon, water, heat and nutrients, biota, greenhouse gases and environment, soil-plant-atmosphere continuum and ways of its regulation to increase efficiency of water, energy and chemicals in agriculture, postharvest management and processing of agricultural and horticultural products in relation to food quality and safety, mathematical modeling of physical processes affecting environment quality, plant production and postharvest processing, advances in sensors and communication devices to measure and collect information about physical conditions in agricultural and natural environments. Papers accepted in the International Agrophysics should reveal substantial novelty and include thoughtful physical, biological and chemical interpretation and accurate description of the methods used. All manuscripts are initially checked on topic suitability and linguistic quality.
