Abstract: In this paper, four types of peat-compound fertilizers were made, which mainly contained five elements of N, P, K, Zn and Fe. Pot experiment of fertilizer effect was conducted by using winter wheat as test crop and red oil soil as test soil. The results showed that all the peat-compound fertilizers significantly increased the biomass and dry root of winter wheat. The fixing effect of soil on Zn, Fe, and P was attenuated and the uptake amounts of the elements were increased. Among the fertilizers, acidizing had the best effect, and the treatment of adding water was next to it. As for fertilizer application methods, layering application was better than mixing application.
