中文摘要	【目的】研究棉秆生物质炭对灰漠土、风沙灌淤土速效磷、钾的影响。【方法】采用室内培养试验,分别以两种土壤为研究对象,设置四个处理,分别为空白土壤(CK)、土壤质量0.5%的棉秆炭(0.5%BC)、土壤质量1.0%的棉秆炭(1.0%BC)、土壤质量2.0%的棉秆炭(2.0%BC);检测不同培育时间,两种土壤的pH、速效磷、速效钾、阳离子交换量(CEC)的变化。【结果】棉秆炭(BC)呈现碱性,随着添加量的增加,不同程度的提高两种土壤pH、速效磷、速效钾、阳离子交换量。其中棉秆炭高剂量(2%)处理能明显提高两种土壤速效磷、速效钾(P<0.05),增加幅度分别为25.21% ~45.79%、10. 24% ~ 28. 05% 、23. 34% ~ 101.17% 、38.95% ~62.36%。【结论】棉杆炭具有激活两种土壤速效磷、速效钾的效应,对土壤保肥能力有一定的影响。
英文摘要	【Objective】 The study focuses on the effect of cotton stem biochar (BC) applied on changing available P and K in grey desert soil and sand irrigated soil.【Method】Two types of soil were taken as trial materials, and four treatments were set, which were 0% biochar (CK), and 0. 5% biochar, 1. 0% biochar and 2.0% biochar, respectively. Indoor incubation experiment was conducted to investigate pH value,and available P,and K,and cation exchange capacity (CEC).【Result】PH value, CEC, available P and K was increased by dosage of BC applied in soil; High dosage of BC (2%) applied would lead to soil available P, and K improvement in short term (P <0.05). The increasing rates were 25.21%-45.79%. 10.24-28.05%. 23.34%-101.17% and 38.95%-62. 36%, respectively.【Conclusion】It was inferred that soil available P and K could be activated through application of cotton stalk biochar, and the applied biochar could improve soil fertility to a certain extent.
