Table 2 Influences of different treatments (FP: farmer conventional fertilization control; BM: bone meal application control; X2: bacteria agent X2; X3: bacteria agent X3; X21: bacteria agent X21) to wheat yield components. Data are shown as Mean ± SD. Different lowercase letters indicate significance among different treatments at the 5% level
