Abstract: Phyllostachys praecox , a favorite bamboo shoot species , has been widely planted in these years .The practice of surplus fertilizing and winter mulching has been conducted to gain good economic benefits .To study the effects of fertilizing and winter mulching on microbial biomass carbon (MBC)in soil , a trial with different types (manure , oil cake and mineral fertilizer)and rates of fertilizers was conducted from August 2002 to April 2003 . The first 3 treatments applied with both fertilizer and manure but with different rate .The highest microbial biomass carbon in soil was measured in October and December , medium one in August and February , and lowest one in April .It was always true that treatments with mixture of fertilizer and manure were detected much more MBC (P 0.05)compared with pure fertilizer treatments, and MBC in soil was increasing with augment of manure amount applied per plot .It was found that winter mulching practice enhanced MBC in soil , and the average ratios of MBC in mulching treatments to non-mulching treatments were 1.60 and 1.52 respectively in February and April .MBC in soil was significantly correlated with total organic carbon , total nitrogen and hydrolysable nitrogen (P 0.05).
