Abstract: In order to determine the effects of increasing bio-organic fertilizers and reducing chemical fertilizers application on production, soil enzyme activity and microbial diversity in winter wheat, a experiment was carried out in Mazhuang Baogaofeng Farm of Xinji City, Hebei Province. On the basis of applying biological organic fertilizer, the chemical fertilizer was reduced for 10%, 30%, 50% and 100%, respectively, taking the conventional fertilization treatment as a control. Compared with conventional fertilization(T5),the yield of winter wheat(T3,T2,T4) was significantly higher, reaching to 6 510.65,6 237.30,6 084.15 kg/ha, respectively.The highest yield came from T3 treatment, increasing by 13.42% compared to T5. Compared with T5, the soil alkaline phosphatase activity of the four bio-organic fertilizer treatment of T1, T2, T3 and T4 increased by 14.33%,15.60%,14.08% and 9.12%, the urease activity increased by 8.22%,7.22%,10.47% and 5.41%, the cellulose activity increased by 63.89%,30.35%,66.45% and 57.19%, respectively. The analysis of soil culture microorganism showed that the total amount of microorganisms, bacteria and fungi in four bio-organic fertilizer treatments were higher than that of T5. However the proportion of fungi decreased. The soil microbial diversity of different treatments was analyzed. The Shannon index, Chao1 index, and ACE index of four bio-organic fertilizer treatments were higher than that of T5. Compared with T5, the Shannon index, Chao1 index, and ACE index of T3 treatment increased by 3.61%, 19.74% and 22.43%, respectively. The proportion of soil microorganisms was changed.

Key words: Winter wheat, Bio-organic fertilizer, Soil enzyme activity, Microbial diversity, Yield increasing effect
