摘要:
为探究添加生物炭对花生土壤碳氮磷化学计量特征及酶活性的影响,采用大田试验,以高油高产的花生品种商花21号为试验材料,分别设置不施肥(CK)和单一施用1.5 t/hm2有机肥(B1)处理,并在B1处理基础上设置 2.5 t/hm2(B2)、3.0 t/hm2(B3)、3.5 t/hm2(B4)、4.0 t/hm2(B5)共计4个生物炭用量处理。研究2023年和2024年花生成熟期0~20 cm表层土壤有机碳(SOC)、全氮(TN)、全磷(TP)含量及其生态化学计量比的变化,以及硝态氮含量、铵态氮含量、酶活性、花生产量的变化,并进行相关性分析。结果表明,在土壤肥力方面,与CK相比,B3、B4处理在连续2年提升土壤SOC、TN、TP、硝态氮、铵态氮含量等指标上综合效果最为明显,B4处理在连续2年提升土壤酶活性方面效果最为显著(P<0.05)。在碳氮磷化学计量比方面,B3、B5处理能够通过提升土壤C/N值,缓解土壤碳缺乏现状,但各处理均存在碳缺乏问题;生物炭添加能够显著提升土壤碳元素含量,但就C/P值而言,土壤碳元素相对短缺,磷元素相对充足;就土壤N/P值而言,各生物炭处理土壤均受氮元素限制。在花生产量方面,与CK相比,2023年各生物炭处理提升花生荚果、籽仁产量方面均未达到显著效果;2024年B4处理提升花生荚果、籽仁产量效果最为显著,增幅分别达10.09%、11.20%。综上可知,B4处理在土壤肥力改善及花生增产方面效果最佳。
