生物炭基肥在我国的制备和应用研究进展

生物炭基肥是实现农作物秸秆资源化利用的一种绿色肥料,因其在农业生产中能够显著提高作物产量和品质而受到广泛关注.然而,生物炭基肥的制备过程影响生物炭基肥的缓释、成型和其他功能性效果,进而对作物产量和品质产生的影响缺乏系统而全面的报道.从生物炭原料、炭肥比、制备方法和制备工艺改性研究4部分阐述了生物炭基肥的制备过程对生物炭...

Research progress on preparation and application of biochar-based fertilizer in China

Biochar-based fertilizer is a kind of green fertilizer to realize the resource utilization of crop straw,which has been widely concerned because it can significantly improve crop yield and quality in agricultural production. However,the preparation process of biochar-based fertilizer affects its slow-release,molding and other functional effects,and further effects on crop yield and quality are not systematically and comprehensively reported. In this review,the influence of the preparation process of biochar on the performance of biochar-based fertilizer was discussed from four parts:the raw material,the ratio of biochar to fertilizer,the preparation method and the modification of the preparation process. The review summarized the effects of the types of biochar-based fertilizer,the ratio of biochar-based fertilizer to chemical fertilizer and the application method on its application effect,and forecasted the great application prospect of biochar-based fertilizer in agricultural operation promotion in China. The review summarized the preparation and application rules of biochar-based fertilizer,providing directions for optimizing the preparation process and perfecting the application system of biochar-based fertilizer,and expecting the application of biochar-based fertilizer in agricultural production to develop in a friendly direction.
