Abstract: This study dealt with the effects of maize stubble remaining in field on dynamics of soil microbial biomass Cand soil enzyme actvities. The results showed that maize stubble remaining in field could raise soil microbial biomass Cand the actvities of urease,phosphatase,cellulase,and invertase in soil remarkably. According to the dynamics of soil microbial biomass Cand activities of the four enzymes,the five characters reached their maximum values about 60 days after sowing,and the crops were in bloom of growth. The results also showed that maize stubble remaining in field had positive effects on improving fertility and keeping high and steady yield of maize.
