ABSTRACT

The replant disease refers to abnormal crop growth caused by continuous cultivation of the same or related species on the same soil, and often occurring in crops and orchards. Recently, replant disease have become a major factor constraining the sustainable development of global agriculture and fruit trees. The causes of replant disease include biological and abiotic factors, but in the final analysis, they are caused by changes in the soil environment. Soil environment is closely related to soil productivity. A decline of soil quality results in poor crop growth and reduced yield. The causes of soil environment changes mainly include intensive soil tillage, rapid industrialization, soil pollution, destruction of soil micro-ecosystem and substances secreted by plants under replant condition. Biochar, a porous carbon material prepared from pyrolysis of biomass (agricultural waste, etc.), is widely used as an amendment and adsorbent. To understand the role of biochar in alleviating replant disease, we summarized the previous research results of biochar application in replant soil. The following points are summarized: (1) soil problems and their effects on plants; (2) effects of biochar on replant soil environment; and (3) effects of biochar on alleviating replant disease. Overall, the literature suggests that biochar is an effective measure to amendment soil environment and alleviates replant disease. Further studies on biochar will enhance our understanding of biochar–soil interactions, and its long-term impact of biochar on soil environment.

摘要

补种病是指由于在相同土壤上连续种植相同或相关物种而导致的作物异常生长，并且经常发生在作物和果园中。最近，再植病已成为制约全球农业和果树可持续发展的主要因素。补植病的原因包括生物学和非生物因素，但归根到底，它们是由土壤环境的变化引起的。土壤环境与土壤生产力密切相关。土壤质量下降导致农作物生长不佳，单产下降。土壤环境变化的原因主要包括耕作密集，工业化进程加快，土壤污染，土壤微生态系统的破坏以及补种条件下植物分泌的物质。生物炭 由生物质（农业废弃物等）热解制得的多孔碳材料被广泛用作改性剂和吸附剂。为了了解生物炭在减轻补植病害中的作用，我们总结了生物炭在补植土壤中应用的先前研究成果。归纳了以下几点：（1）土壤问题及其对植物的影响；（2）生物炭对复种土壤环境的影响；（3）生物炭对减轻补植病的作用。总体而言，文献表明生物炭是改善土壤环境和减轻补植病害的有效措施。关于生物炭的进一步研究将增进我们对生物炭-土壤相互作用及其对土壤环境的长期影响的理解。为了了解生物炭在减轻补植病害中的作用，我们总结了生物炭在补植土壤中应用的先前研究成果。归纳了以下几点：（1）土壤问题及其对植物的影响；（2）生物炭对复种土壤环境的影响；（3）生物炭对减轻补植病的作用。总体而言，文献表明生物炭是改善土壤环境和减轻补植病害的有效措施。关于生物炭的进一步研究将增进我们对生物炭-土壤相互作用及其对土壤环境的长期影响的理解。为了了解生物炭在减轻补植病害中的作用，我们总结了生物炭在补植土壤中应用的先前研究成果。归纳了以下几点：（1）土壤问题及其对植物的影响；（2）生物炭对复种土壤环境的影响；（3）生物炭对减轻补植病的作用。总体而言，文献表明生物炭是改善土壤环境和减轻补植病害的有效措施。关于生物炭的进一步研究将增进我们对生物炭-土壤相互作用及其对土壤环境的长期影响的理解。（2）生物炭对复种土壤环境的影响；（3）生物炭对减轻补植病的作用。总体而言，文献表明生物炭是改善土壤环境和减轻补植病害的有效措施。关于生物炭的进一步研究将增进我们对生物炭-土壤相互作用及其对土壤环境的长期影响的理解。（2）生物炭对复种土壤环境的影响；（3）生物炭对减轻补植病的作用。总体而言，文献表明生物炭是改善土壤环境和减轻补植病害的有效措施。关于生物炭的进一步研究将增进我们对生物炭-土壤相互作用及其对土壤环境的长期影响的理解。
