%X 山东省作为中国核心烟叶产区&#65292;砂质土占比超60%&#65292;其保水保肥能力弱、养分贫瘠等问题严重制约烟草优质生产。本文系统解析砂质土物理、化学及微生物特性&#65292;揭示其对烟草根系发育、产量和品质的影响机制。通过集成有机物料改良、无机肥精准调控与保水剂应用&#65292;实现烟叶上等烟比例提高及产值增长。研究证实&#65292;技术协同可降低水土流失&#65292;但长期生态风险监测与低成本材料开发仍需突破。本文为砂质土烟田生态&#8211;经济协同管理提供理论依据和技术范式。<br>As a core tobacco-producing area in China, Shandong Province has more than 60% sandy soils, which are weak in water and fertilizer retention and poor in nutrients, severely restricting the quality production of tobacco. This paper systematically analyses the physical, chemical and microbiological properties of sandy soils, and reveals their influence mechanisms on tobacco root development, yield and quality. Through the integration of organic material improvement, inorganic fertilizer precision control and water retention agent application, the proportion of top-grade tobacco is increased and the production value is increased. The study confirms that technological synergy can reduce soil erosion, but long-term ecological risk monitoring and low-cost material development still need breakthroughs. This paper provides a theoretical basis and technical paradigm for the ecological-economic synergistic management of tobacco fields in sandy soils.
