【 摘 要 】

The object of this study was to investigate the impact of application biocar on peanuts growing. It was based on a long-term fertilization experiment which researched the effect of applying different amounts of biochar and BBF when continuously cropping peanuts for 5 years. There were five treatments: No fertilizer, low level of biochar (C15), high level of biochar (C50), chemical nitrogen-phosphorus-potassium (NPK) fertilizer and biochar-based fertilization (BBF).We determined peanuts stem and leaf weight, root weight, plant and the relative content of chlorophyll at every growth stages in 2016. The results showed that all fertilization can increase these indexes and in application of NPK improve them the most which close to BBF. The peanuts stem and leaf weight, root weight, plant and the relative content of chlorophyll was higher than the same level carbon treatment (C15) 62.85%, 6.67%, 18.73% and 25.58%, respectively. Expect stem and leaf weight, plant height, root weight and chlorophyll were higher when high level biochar (C50) applied than the low one (C15).
