摘要

Biochar is a carbon rich solid residue produced when biomass is heated with little or no availableoxygen at relatively low temperature. Its use in agriculture as soil amendment had been found to enhance soilquality and increase crop productivity. Acidic soil amended with biochar produced from waste basal portions ofbamboo was tested by growing mung bean in a randomized complete block design experiment. Results showedthat plants grown in soil amended with 8.5 and 15.75%w biochar started flowering, pod filling and maturing 6to 7 days earlier than those grown in un-amended soil. After 60 days, plants in the biochar amended soil weresignificantly taller by about 27% and their pod production was 102% higher than those without biochar.Addition of vermicast to biochar-amended soils did not significantly enhance the flowering and pod filling stagesof mungbean and likewise did not significantly increase pod production rate. Root nodules of plants grown insoils without biochar formed at the base near the soil surface while nodulation extended down the whole lengthof the roots in soils amended with 8.5 and 15.75%w biochar. The addition of vermicast resulted in fewernodules but in effect enhanced rootlet formation. There was a continually increasing trend in pH during thevegetative growth of the plant up to maturity both in the control pots and those amended with biochar. Theresults suggest that bamboo biochar can be an efficient and cost effective way of improving soil quality and aidin sustainable crop production in regions with acidic soils.
