Abstract：In order to explore the effect of compound microbial agents on growth and yield structure of Huamai 1028.In this paper,through field experiment,four treatments were set up to explore the effects of only the compound microbial agents alone and compound microbial agents on the basis of conventional fertilization on growth period,plant height,overwintering seedlings,peak seedlings,spike formation rate,effective spike number,spike length,grain number per spike,thousand-grain weight and other field phenotypes and yield structure of Huamai 1028.The results showed that the yield of treatment 2 increased by 5.3％compared with CK,and the yield of treatment 3 increased by 15.1％compared with treatment 4.At the same time,overwintering seedlings,peak seedlings,spike formation rate,effective spike number,grain number per spike were significantly increased compared with the control.Under the treatment of no the application of conventional fertilizer and only the addition of compound microbial agents,the growth period of wheat was one day later than that of CK.Under the condition of normal fertilization,the growth period of adding biological agent was one day earlier.It can be seen that the compound microbial agent can improve the yield structure of wheat,increase the utilization rate of chemical fertilizer,and regulate the growth period.
