原文摘要

This summary chapter highlights the advances achieved in biochar research and the existing barriers to biochar application. Substantial research over the past decade on biochar production, characterization, and utilization indicates that biochar is a promising agricultural and environmental amendment for improving soil functions, reducing greenhouse gas emissions, mitigating contamination, and enhancing animal health. Biochar can be readily produced by thermal treatment of nearly all biomass materials. The quality of biochar, however, varies with the feedstock type, carbonization conditions, and post‐treatment handling. The beneficial effects of biochar amendment may fluctuate, depending on the soil needs, the biochar quality, application rate, the site conditions, and time following application. Biochar application is currently in its infancy, with the main barriers identified as the gap between research and application, immaturity of economical production technologies, lack of application‐specific quality standards and management programs, inadequate policy and financial support, and low awareness among end users.

原文摘要簡述

本概述章節重點介紹了生物炭研究獲得的發展成就以及生物炭應用上現有的障礙。在過去十年中,有關生物炭生產、表徵和利用的大量研究表明,生物炭是一種有前途的農業及環境改良劑、改善土壤功能、減少溫室氣體排放、減輕污染並增強動物健康。近乎所有生物質材料通過熱處理後,可以輕鬆生產生物炭。但是,生物炭的品質隨料源類型、炭化條件和後處理方式而不同。生物炭改良的效益可能會有所波動,具體取決於土壤需求、生物炭質品質、施用量、施用地點條件以及施用後的時間。生物炭的應用目前尚處於起步階段,主要障礙是研究與應用之間的差距、經濟生產技術的不成熟、缺乏針對特定應用的品質標準和管理計畫、政策和財務支持不足以及最終使用者的意識低下。
