The invention discloses a composite microbial granulated
fertilizer containing medium trace elements. The composite microbial granulated
fertilizer comprises the following components in parts by weight: 50-90 parts of medium trace elements, 0.2-5 parts of a composite
microbial agent and 8-12 parts of an
adhesive, wherein the medium trace elements refer to monohydrates or
anhydrous compounds. Rich soil scarcity
nutrient is provided by utilizing the medium trace elements, the composite microbes provide an excellent root micro-
ecological environment, substances such as
auxin are secreted, absorption of crops on large, medium and trace elements is further promoted, the
nutrient proportioning is reasonable, the
fertilizer efficiency is high, the fertilizer absorption level of the crops can be greatly improved, the production cost is reduced, the problems such as various
nutritional deficiency symptoms of the crops and low
root disease resistance and cultivation of resilience are solved, the resistance of the crops is enhanced, and the yield and quality are improved. In the
granulation process, the characteristic that each material is stable in water absorption is fully utilized, the
energy consumption is reduced, and emission of
greenhouse gas and three wastes is avoided. Moreover, different requirements of various soil types and
crop varieties in China on the medium trace elements and composite microbes can be met.
