生物炭及生物炭基肥在农业中的应用研究进展

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。

Research Progress of Application of Biochar and Biochar-based Fertilizer in Agriculture

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 ap-plied 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 bio-char 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 ferti-lizer 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.
