摘要
生物炭作为一种土壤改良剂,可改善土壤结构和理化性状.将生物炭与养分混合制成的炭基肥具有延缓养分释放和降低养分淋失的优点,是一种环保型肥料,在农业上具有巨大的应用潜力.研究表明,生物炭及炭基肥的施用能有效改善土壤理化性质,提高土壤微生物丰度,促进植物生长.该文主要从生物炭及炭基肥对土壤理化性质、土壤微生物群落、植物生长和养分吸收等方面的影响进行综述,并对生物炭及炭基肥的应用提出展望.
Abstract
Biochar can improve soil structure and properties when applied as a soil amendment.The biochar-based fertilizers made by mixing biochar with nutrients has the advantages of delayed nutrient release and reduced nutrient leaching,which is an environmentally friendly fertilizer with great application potential in agriculture.Studies have shown that the application of biochar and biochar-based fertilizers can effectively improve the physical and chemical properties of soil,increase the abundance of soil microorganisms,and promote plant growth.In the present study,the research progress of biochar and biochar-based fertilizers in agriculture in terms of their effects on soil physical and chemical properties,soil microbial communities,plant growth and nutrient uptake was reviewed,and prospects for the application of biochar and biochar-based fertilizers in agriculture were proposed.
