浸酸

The pH value in soil was significantly increased in litter aqueous extract of four decomposition stages. The NH+4-N concentration was significantly decreased in soil amended with litter aqueous extract of 10-day decomposition which promoted the growth of Aerobic azotobacter and Ammonifier but inhibited the growth of Aerobic cellulose-decomposer. Available phosphorus concentration was significantly increased and phenolic acid content was significantly decreased in soil amended with litter aqueous extract of 60-day decomposition which inhibited the growth of Aerobic azotobacter but promoted the growth of Aerobic cellulose-decomposer.
