摘要
本文选用餐厨废弃物、炭化谷壳、炭化烟秆按比例混合后施入土壤进行室内培育,以探讨其对土壤pH和土壤有效养分的影响,为酸性土壤调理剂的研制提供依据。结果表明:施用餐厨废弃物及生物质炭均可有效提高土壤pH值,至培育9d时,施用调理剂的各个处理比对照处理(CK)增加了0.13~0.78个单位;至培育90d时,D处理(餐厨废弃物3.2g+炭化烟秆0.4g+炭化谷壳0.4g)、E处理(餐厨废弃物2.8g+炭化烟秆0.8g+炭化谷壳0.4g)和G处理(餐厨废弃物2.4g+炭化烟秆0.8g+炭化谷壳0.8g)能有效提高土壤碱解氮、有效磷、速效钾含量,显著高于对照处理(CK)。综合土壤pH值和有效养分,G处理和E处理培育土壤效果较佳,餐厨废弃物混合生物质炭对土壤肥力有良好的培育作用。
In this paper,kitchen waste,carbonized husk and carbonized tobacco stalk were mixed in proportion and applied to the soil for indoor cultivation,so as to explore their effects on soil pH and soil available nutrients,to provide a basis for the development of acid soil conditioner.The results showed that the application of kitchen waste and biochar could effectively improve the soil pH value.At 9d of incubation,each treatment with conditioner increased by 0.13~0.78 units compared with the control treatment(CK);At 90d of incubation,treatment D(3.2g of kitchen waste+0.4g of carbonized tobacco stalk+0.4g of carbonized husk),treatment E(2.8g of kitchen waste+0.8g of carbonized tobacco stalk+0.4g of carbonized husk)and treatment G(2.4G of kitchen waste+0.8g of carbonized tobacco stalk+0.8g of carbonized husk)could effectively improve the contents of soil alkali hydrolyzable nitrogen,available phosphorus and available potassium,which were significantly higher than those of the control treatment(CK).Combined with soil pH value and available nutrients,G treatment and E treatment had better soil cultivation effect,and kitchen waste mixed biomass carbon have a good cultivation effect on soil fertility.
