不同土壤条件下水稻生长及产量影响研究
摘 要
水稻作为全球最重要的粮食作物之一，其生长和产量受土壤条件影响显著。本研究旨在探讨不同土壤条件下水稻的生长特性及产量变化，选取了砂质土、壤土和黏土三种典型土壤类型，在相同气候条件下进行对比实验。通过分析土壤理化性质、水稻植株生理指标以及最终产量，发现壤土中水稻生长状况最佳，表现为根系发达、叶片光合效率高且产量最高；砂质土通气性好但保水保肥能力差，导致水稻生长受限；黏土虽保水保肥能力强，但通气性差影响根系发育。创新点在于系统评估了土壤结构对水稻生长全过程的影响，并建立了土壤特性与水稻生长响应之间的定量关系模型，为优化水稻种植土壤管理和精准农业提供了理论依据和技术支持，有助于提高水稻产量和质量，保障粮食安全。

Impact Of Rice Growth And Yield Under Different Soil Conditions
ABSTRACT
Rice, as one of the world's most important food crops, is significantly influenced by soil conditions in terms of growth and yield. This study aims to investigate the growth characteristics and yield variations of rice under different soil conditions. Three typical soil types—sandy soil, loamy soil, and clay soil—were selected for comparative experiments under identical climatic conditions. By analyzing soil physicochemical properties, physiological indicators of rice plants, and final yields, it was found that rice grown in loamy soil exhibited the best growth performance, characterized by well-developed root systems, high leaf photosynthetic efficiency, and the highest yield. While sandy soil has good aeration but poor water and nutrient retention, leading to restricted rice growth; clay soil, although having strong water and nutrient retention capabilities, suffers from poor aeration which affects root development. The innovation lies in systematically evaluating the impact of soil structure on the entire growth process of rice and establishing a quantitative relationship model between soil characteristics and rice growth responses. This provides theoretical basis and technical support for optimizing soil management in rice cultivation and precision agriculture, contributing to increased rice yield and quality, and ensuring food security.
