Abstract:

【目的】生物碳可提高土壤肥力,增强土壤对养分的保持能力,减少养分损失,提高肥料利用率。研究不同温度热解制备的生物碳对棉花生长和肥料利用率的差异,可以为提高生物碳的有效利用提供依据。【方法】供试生物碳由棉花秸秆分别在450℃、600℃和750℃高温限氧条件下热解制备而成。本试验为两因素(生物碳、氮)温室盆栽试验,生物碳处理包括3种不同热解温度生物碳处理(分别以450BC、600BC、750BC表示)和1个空白对照(CK);每个生物碳土壤设置3个施氮水平0、2.1和4.2g/pot(分别以N0、N1、N2表示),用15N同位素示踪方法分析不同施氮水平下3种热解温度生物碳对棉花生长、15N回收和淋洗损失的影响。【结果】1)施用3种生物碳处理棉花干物质重总体表现为750BC>600BC、450BC>CK,450BC、600BC和750BC处理分别较对照平均增加了9.2%、12.6%和17.3%;并且棉花总干物质重随施氮量的增加而增加,但生物碳作用随之降低;2)3种生物碳处理棉花氮素吸收总量总体也表现为750BC>600BC、450BC>CK。不施氮肥条件下(N0),600BC和750BC处理棉花氮素吸收总量显著高于CK,但450BC处理与与CK无显著差异;施氮肥条件下(N1、N2),3种生物碳处理均显著高于CK,450BC、600BC和750BC处理棉花氮素吸收总量平均较CK分别增加29.5%、37.1%和48.8%;3)15N标记试验结果表明,450BC、600BC和750BC处理植株15N回收率显著高于对照,分别较CK平均提高27.46%、36.44%和42.87%。而N1和N2水平下3种生物碳处理之间植株15N回收率均没有显著差异;4)450BC、600BC和750BC处理土壤15N残留率分别较对照平均增加101.4%、147.3%和200.7%。土壤15N残留率在N1水平下随着生物碳热解温度的升高而增加,而在N2水平下750BC处理显著高于450BC和600BC处理,但是后二者之间没有显著差异。土壤15N残留率随着施氮量的增加而降低;5)施用生物碳可以显著降低土壤15N的淋洗,并且不同施氮水平下(N1、N2)淋洗率都随着生物碳热解温度的升高而降低。【结论】施用生物碳可促进棉花生长,增加棉花氮素吸收,提高氮肥利用率,降低氮素损失,并且生物碳的热解温度越高效果越明显;但是随着氮肥施用量的增加生物碳作用减弱。
