生物炭及炭基肥影响农田土壤改良效应的研究进展

Research Progress on Improvement Effects of Biochar and Biochar-based Fertilizer on Cropland Soils

我国南方农田普遍存在土壤酸化加速、土壤肥力和质量不断下降、土壤微生物群落结构和功能失调等土壤退化现象。近年来,大量研究表明生物炭是一种应用前景广阔的土壤改良剂,而将其与肥料有效结合制成生物炭基肥,将在我国农田酸化土壤改良和作物增产等方面发挥重要作用。本文重点针对生物炭和生物炭基肥在农田生态系统中影响土壤改良的效应进行了综述,旨在为我国南方农田土壤改良和农业生产可持续发展提供参考。

In the cropland of southern China,the soil showed a degradation:soil acidification accelerates,soil fertility and quality constantly decline,and soil microbial community structure and function are uneven.Recently,a large number of studies showed that biochar was a kind of soil amendment with broad application prospects.Biochar can be effectively mixed with fertilizer to produce biochar-based fertilizers,which will play an important role in improving acidification soil and crop yield increase.In this paper,research progress in effects of biochar and biochar-based fertilizer on soil improvement in agroecological system was reviewed,aiming to provide references for the improvement of cropland soil and the development of sustainable agriculture production in southern China.
