Effects of partial fertilizer substitution by organic fertilizer on growth of peanut at seedling stage

[摘要] In response to the Ministry of agriculture's action plan for chemical fertilizer reductions and organic fertilizers instead of fertilizersand discuss the optimum consumption and proportion of peanut biochar-based fertilization.Six different fertilization treatments were set up:C40, C50(standard consumption), C60, C40+M, C30+M and C20+M. Seelding height, chlorophyll content and total biomass were also measured on 6th, 2017. The results showed that C20+M treatment had the highest plant height and the highest biomass in Peanut Seedlings, while the content of chlorophyll increased with the amount of biochar applied.
