摘要:

生物炭作为一种土壤改良剂应用到农田土壤中,能够在很大程度上改善土壤物理结构、提高土壤养分转化效率,缓解不合理生产制度所造成的土壤退化问题,对促进农业增产、保障国家粮食安全、提高土壤资源的可持续利用具有重要意义。本文通过分析和总结国内外专家对秸秆生物炭在农田中应用的研究成果,提出今后的研究方向,为农业生产中生物炭的应用提供理论支持。通过查阅和分析相关文献、资料,重点讨论了不同材料、热解温度的生物炭对农田土壤理化性质和作物生长的影响。目前,国内外对生物炭在改善土壤质量和生产力等方面的应用进行大量的试验,虽取得了一定的成果,但尚未形成一套完整的理论体系来阐述生物炭的生产方式、施用量等对农业生产的影响。土壤是一个复杂的环境,多种因素起着冲突作用,土壤—生物炭的相互作用还未完全被了解,在今后的研究中可适当调整实验设计,最大限度提高生物炭性能。

Abstract:

Biochar, as a kind of soil conditioner, can improve the physical structure of soil, enhance the efficiency of soil nutrient transformation and alleviate soil degradation caused by unreasonable production system. It is of great significance to promote agricultural production, ensure national food security and improve the sustainable utilization of soil resources. This paper analyzes the research results of domestic and foreign experts on the application of straw biochar in farmland, and puts forward the research direction in the future, aiming to provide theoretical support for the application of biochar in agricultural production. The effects of biochar with different materials and pyrolysis temperature on soil physical and chemical properties and crop growth are discussed by consulting and analyzing relevant literature and materials. At present, a large number of experiments have been carried out on the application of biochar in improving soil quality and productivity at home and abroad. Although some achievements have been made, a complete theoretical system has not been formed to elaborate the influence of biochar production mode and application rate in agricultural production. Soil has a complex environment, and many factors play a role in conflict. The interaction between soil and biochar has not been fully understood. In the future, we can adjust the experimental design to maximize the performance of biochar.

Key words: straw, biochar, soil conditioner, soil, physical and chemical properties of soil, crop growth, crop yield
