There were 3 treatments including wheat straw derived (WBF), peanut shell derived (PBF) and cotton straw derived (CBF) biochar-based fertilizer, the total nutrient was 37%, with N:P O :K O=18:9:10 in this trial, and control 2 5 2 experiment with the application of normal compound fertilizer, the total nutrient was 45%, with N:P O :K O=15:
