Abstract

[Objective] To demonstrate the effects of water-soluble organic carbon in biochar for crop growth and quality and to open up new pathway for the application of biochar.[Methods] Three wheat straw biochar samples at 400℃

450℃

500℃ were prepared in laboratory

and corresponding water-soluble organic carbons were extracted with KOH solution to obtain biochar extracts of W400

W450

W500. Furthermore

the extracts were applied in potted garlic test and the effects on garlic growth

quality and soil were measured.[Results] (1) W400

W450

W500 had no significant effects on the growth of garlic. (2) W400 treatment increased the content of garlic soluble sugar by 27.53%

increased soil organic matter and available phosphorus by 37%

26%. (3) Garlic vitamin C

allicin content in the treatment of W450 was significantly increased by 34.9% and 8.2%.[Conclusion] Biochar extract has no effect on the growth of garlic

but it can improve the quality of garlic.
