Abstract
An experiment was done in plots of summer maize field with different fertilizer treatments.The results show that the soil organic matter,total nitrogen and available nitrogen are higher in the plots applied with EM compost than those applied with the same amount of traditional compost and chemical fertilizer.LAJ.1eaf chlorophyll content.the biomass of canopy,leaves stems,ears and grains of maize,which have similar variation trends in different fertilizer treatments,were higher in plots applied with EM compost than those applied with the same amount of traditional compost and chemical fertilizer.The more the compost input,the more obvious difference in the values.Maize yields in the plots applied with EM compost fire 11%- 20% higher than those applied with the same amount of traditional compost.The more the cornpost input,the more remarkable increase of the maize yield.
