摘 要
本文探讨了农业土壤多样性对作物生长和产量的影响，重点是玉米生产。文章从土壤类型分类开始，分析了土壤的全球分布和多样性，包括物理、化学和生物特性。接着，文章讨论了土壤功能的多样性，如养分循环、水分调节和污染物降解，这些功能对农业生态系统健康至关重要。文章强调了土壤理化性质对作物生长的重要性，指出土壤为作物提供生长环境，供应和调节养分，影响微生物群落结构和土壤健康。针对玉米，文章探讨了不同土壤类型对其产量的影响，包括土壤质地、结构、养分、酸碱度和污染等问题。最后，提出了提高玉米产量的策略，包括改良土壤结构、建立排水系统、增加有机质、合理施肥、调节土壤pH值和控制污染，以保障玉米高产稳产。

EFFECT OF DIFFERENT SOIL TYPES ON MAIZE YIELD
ABSTRACT
This paper explores the effects of agricultural soil diversity on crop growth and yield, with a focus on maize production. Starting with soil type classification, the global distribution and diversity of soil, including physical, chemical and biological properties. Next, the diversity of soil functions, such as nutrient cycling, water regulation, and pollutant degradation, that are critical for agroecosystem health. This paper emphasizes the importance of soil physicochemical properties for crop growth, pointing out that soil provides a growth environment for crops, supplies and regulates nutrients, and affects microbial community structure and soil health. For maize, the paper discusses the effects of different soil types on their yield, including soil texture, structure, nutrients, pH and pollution. Finally, strategies to improve the maize yield, including improving soil structure, establishing drainage system, increasing organic matter, rational fertilization, regulating soil pH and pollution control, were proposed to ensure high and stable maize yield.
