NOVELTY - An installation agriculture garbage anaerobic fermentation fertilizer is formed by uniformly storing collected installation agriculture garbage, and cutting plant straws via mechanical or manual form; fetching bottom percolate of anaerobic fermentation tank before loading to uniformly mix with cut straw, and placing mixed material to anaerobic fermentation tank; using middle-temperature fermentation, and enabling percolate to flow out of fermentation tank; and directly applying fermented plant straw to field, using as organic fertilizer after machining, and metering and packaging.    USE - Method for forming installation agriculture garbage anaerobic fermentation fertilizer (claimed).    ADVANTAGE - The method solves problems of conventional stack and embedded disposal. The installation agriculture garbage is converted from waste into fertilizer through anaerobic fermentation. It is not only effective measure of treating rural pollution and improving rural landscape but also forceful push of rural circular economy. The high-efficiency recycling of the installation agriculture garbage is realized. The industrial chain of installation agriculture garbage is widened. The resource utilization link is prolonged.    DETAILED DESCRIPTION - Installation agriculture garbage anaerobic fermentation fertilizer is formed by:    (A) uniformly storing collected installation agriculture garbage, cutting plant straws via mechanical or manual form, and controlling length of cut plant straw to 1-5 cm;    (B) fetching bottom percolate of anaerobic fermentation tank before loading to uniformly mix with cut straw, and placing mixed material to anaerobic fermentation tank;    (C) using middle-temperature fermentation in anaerobic fermentation tank, enabling percolate to flow out of fermentation tank to be used as inoculation material liquid of next batch of material after treatment within one fermentation period (about 30 days), and salvaging fermented plant straw out for future use; and    (D) directly applying fermented plant straw to field after being dried, using as organic fertilizer after machining, and metering and packaging so as to sell.
