Different lowercase letters in the same column indicate differ significantly at the 0.05 level (P < 0.05), while different capital letters indicate differ extremely significantly at the 0.01 level (P < 0.01). CK, control; FO1, combination of 60% chemical fertilizer with organic manure of 150 kg/ha; FO2, combination of 60% chemical fertilizer with organic manure of 300 kg/ha; FO3, combination of 60% chemical fertilizer with organic manure of 450 kg/ha. TN, total nitrogen; AN, available nitrogen; AP, available phosphorus; SOM, soil organic matter.
