【摘要】 生物炭可作为土壤改良剂单独施入土壤,改善土壤环境条件,也可与肥料混合制成生物炭基肥,其具有养分缓释、增产稳定等一系列优点,在农业上的应用越来越广泛。主要从生物炭对土壤理化性质、微生物、农业温室气体排放、作物生长和产量的影响,对农田土壤污染的治理,以及生物炭基肥对肥料养分、作物生长和产量的影响这几个方面,对生物炭及生物炭基肥在农业中的应用研究进展进行综述,阐明其优点和不足,并提出了进一步的研究方向,旨在为生物炭和生物炭基肥在农业中的应用研究提供参考。更多还原

【Abstract】 When biochar is putted into the soil alone,it can be used as a soil conditioner to improve soil conditions. Additionally,it can be combined with fertilizer,turning into biochar-based fertilizer,with a series of advantages such as slow-release of nutrients,stable increase of yield,etc.,which is being applied more and more widely in agriculture. This paper reviewed the research progress of application of biochar and biochar-based fertilizer in agriculture mainly from following several aspects: the effect of biochar on soil physical and chemical properties,microorganisms,greenhouse gas emissions,crop growth and yield,the management of biochar on pollution of farmland soil,and the effect of biochar-based fertilizer on fertilizer nutrients,crop growth and yield,and clarified the advantages and disadvantages. The further research issues were also proposed,which would provide references for the application of biochar and biochar-based fertilizer in agriculture.更多还原
