摘　　要：针对庐山红壤肥力水平较低的状况,为更好地提升庐山红壤肥力,改善庐山红壤质量,将不同施用量(0%、1%、2%、5%)生物质炭添加到庐山红壤中,并进行培养试验。通过检测庐山红壤总有机碳和颗粒有机碳含量,探讨生物质炭施用对庐山红壤颗粒有机碳含量的影响。结果表明,相比于不施用生物质炭的对照(0%),施用1%、2%、5%生物质炭后,庐山红壤总有机碳含量分别增加了52.77%、107.89%、298.87%,颗粒有机碳含量分别增加了2.99 g/kg、6.56 g/kg和17.63 g/kg,且随着生物质炭施用量的增加,红壤总有机碳含量和颗粒有机碳含量也随之增加。研究结果对于提升庐山红壤肥力,改善庐山红壤质量具有重要理论和实践意义。In view of the lower fertility levels of Lushan Mountain's red soil,the changes of total organic carbon and particulate organic carbon content with different addition amount of biochar(0%,1%,2%,and 5%)to soil were detected and analyzed.The results showed the treatment of 1%,2%,and 5%biochar addition increased total organic carbon content by 52.77%,107.89%and 298.87%,respectively,compared with the control treatment without biochar.The treatment of 1%,2%,and 5%biochar addition increased particulate organic carbon content by 2.99 g/kg,6.56 g/kg and 17.63 g/kg,respectively,compared to the control treatment of non-biochar.Total organic carbon content and particulate organic carbon content were also increased with the increase of biochar addition amount.The results are of great significance to improve the quality of Lushan Mountain's red soil,and provide theoretical basis and practical guidance for the application of biochar in Lushan Mountain's red soil.
