【摘要】 本文主要采用蔗渣为生物质原料,经过热解处理制备蔗渣生物质炭,并施用到蔗田土壤中,在实验室条件下分别培养30天和60天,研究其对蔗田土壤理化性质的影响。研究结果表明:蔗渣生物质炭施用于蔗田土壤30天、60天后,蔗田土壤含水率、p H、阳离子交换量、有机质、全氮、全磷和速效磷含量与空白对照组CK相比均有不同程度增加,其中5%施用量的生物质炭处理对土壤有机质、全氮、全磷和速效磷含量有显著影响。更多还原

【Abstract】 In this study, we mainly evaluated biochars which was produced by muffle furnace with Guangxi common agricultural waste bagasse under different temperatures(450℃、550℃、650℃), and adding bagasse biochar to soil for 30 days and 60 days in the laboratory, in order to research the effect of soil physicochemical properties in Guangxi. And the results were as follows: After bagasse biochar applied to soil for 30 days and 60 days, sugarcane soil moisture content, p H, cation exchange capacity, organic matter, total N, total P and available P content were increasing compared to the treatments without biochar. And soil treated with 5% of biochar had a significant effect on organic matter, total N, total P and available P content.更多还原
