中文摘要	【目的】生物质炭是有机物原料在完全或部分缺氧条件下,高温裂解产生的一类富碳、高度芳香化和稳定性高的有机物质。生物质炭对土壤物理和化学性质具有明显的改良作用,不同原料来源的生物质炭和土壤类型对其的改良效果也存在不同。【方法】以450℃炭化1 h的棉秆炭为试材,通过室内培养试验(80 d,25℃),研究添加0.0%(BC0)、0.5%(BC0.5)、1.0%(BC1.0)和2.0%(BC2.0)棉秆炭对灰漠土土壤性质的影响。【结果】添加棉秆炭能够提高灰漠土的pH值、电导率、CEC、有机碳和全氮含量,并随添加量的增加而增加,碱解氮含量与棉秆炭添加量之间呈负相关关系;在培养时间的80 d内,pH值、有机碳和全氮含量随培养时间的延长而降低,分别降低了6.02%、3.11%和17.72%,电导率和CEC提高了12.07%和49.48%。【结论】添加棉秆炭增加了灰漠土有机碳储量,增强了阳离子交换性能,提高了土壤肥力,有利于新疆灰漠土土壤生产力的提高。
英文摘要	【Objective】Biochar is an organic material with high carbon content,most aromatic structure and great stability resulting from high temperature thermal conversion of organic materials under the complete or partial anoxic condition. Biochar can improve soil physical and chemical properties,but these have different improvement effect of biochar from different raw and soil types. 【Method】In the study,the cotton stalk-char(BC)was carbonized by 1 hour at 450℃ as the test material and mixed with gray desert soil under different rates of addition levels(0,0.5%,1.0% and 2.0%),and incubated for 80 days at 25℃.【Result】The results showed that the pH value,EC,CEC,soil organic carbon and total N of gray desert soil were increasing while the amount of cotton stalk-char increasing,and available nitrogen has a negative correlation with cotton stalk-char. Incubated for 80 days,pH value,soil organic carbon and total N decreased by 6.02%,3.11% and 17.72% with incubation time,respectively. On the contrary,EC and CEC increased by 12.07% and49.48%.【Conclusion】So these results showed that application of cotton stalk-char was an efficient way of increasing soil carbon reserve,enhancing soil cation exchange capacity,improving soil fertility and promoting soil productivity.
