摘要

Biochar of agricultural and forestry waste is one of the core ways to solve the greenhouse effect, and it is also the key measure to improve the land productivity of China’s low yield fields and realize the sustainable development of agriculture. Due to the large area of China’s albic soil, the long-term drought and flood disasters make it a typical low-yield field, which has not been effectively treated. Biochar provides new hope for improving low-yield albic soil. This paper introduces the basic properties of biochar, the albic soil formation mechanism, the low yield of albic soil factors and the improving theoretical basis of biochar. The paper introduces the technical features of the albic soil improvement and the advantages of the albic soil improvement by biochar. In the view of ascending low production potential, solving the greenhouse effect, achieving agricultural sustainable development, the application value and development prospects of albic soil improved by biochar are discussed.
