摘要

本研究旨在评价低阶煤对钠盐碱地玉米（Zea mays）导热系数、土壤水分和生长的影响。从塞萨尔州（哥伦比亚）采集钠盐渍土，用0、2和4吨/公顷的低阶煤处理土壤样品（2公斤）。使用哥伦比亚玉米菌株ICA 109。在建立实验后10天，在现场测量土壤热导率。结果表明，添加低阶煤可显著降低土壤导热系数，玉米植株成活率达36%。结果表明，2 t/ha低阶煤处理对促进植物生长最为有利。

Impacto de la adición de carbón de bajo rango en la conductividad térmica del suelo salino sódico

This study focuses on evaluating the effect of low-rank coal on thermal conductivity, soil moisture, and growth of maize ( Zea mays ) in sodium saline soil. Sodium saline soil is collected from the state of Cesar (Colombia) and soil samples (2 kg) are treated with 0, 2, and 4 t/ha of low-rank coal. The Colombian maize strain ICA 109 is used. Soil thermal conductivity is measured in situ 10 days after establishing the experiment. The results show that adding low-rank coal caused a significant decrease in soil thermal conductivity and a 36% survival rate of maize plants. It is concluded that the 2 t/ha low-rank coal treatment is best for promoting plant growth.
