The invention discloses a preparation method of a coordination polymer containing CuII and research on the inhibition effect of the coordination polymer on soil urease and nitrifying bacteria, and relates to the technical field of fertilizer.The preparation method comprises the steps that 3-aminopyridine and fumaric acid serve as raw materials to synthesize N1, N4-bis (3-pyridyl)-2-butenamide, then CuCl2. 2H2O and the synthesized N1, N4-bis (3-pyridyl)-2-butenamide are used for preparing the coordination polymer containing CuII. The novel coordination polymer [Cu (3-bbpa) (5-HIPA). H2O] is synthesized from N, N, N, N ', N'-bis (3-pyridyl)-2-butenamide and 5-hydroxyisophthalic acid by a hydrothermal method, and the crystal structure of the novel coordination polymer [Cu (3-bbpa) (5-HIPA). H2O] is analyzed to research the influence of the novel coordination polymer as an inhibitor on soil urease and nitrifying bacteria. The difunctional inhibitor is studied to delay the conversion process of urea from urea nitrogen to ammonium nitrogen and ammonium nitrogen to nitrate nitrogen, overcomes the defect of single inhibition capability of a traditional inhibitor, is strong in inhibition capability, low in toxicity, low in cost and simple in synthesis method, can effectively improve the utilization rate and stability of the fertilizer urea, and has a wide application prospect. Nitrogen loss in agricultural activities is reduced, the fertilization cost is reduced, and the grain yield is increased.

Disclosed is an ecological building with an organic agricultural aquaculture function and an internal circulation treatment function. The ecological building comprises a production maintenance passage (20) arranged on the building and located on an elevation of an external wall of each storey. Replaceable planting boxes (3) are arranged on an external wall of the building, each kitchen in the building is provided with a garbage crusher, and each toilet in the building is provided with a vacuum toilet system. A biogas digester (7) is in communication with a vacuum base station (8), the vacuum base station (8) is connected to the vacuum toilet system via a vacuum pipeline (10), the biogas digester (7) is in communication with a biogas slurry storage pool via a biogas slurry pipeline (11), and an inlet end of the biogas digester (7) is connected to a discharge port of the garbage crusher via a black water delivery pipeline (12). The ecological building realizes ecological environmental protection and zero discharge of household garbage, and has an organic agriculture production function and an internal circulation treatment function.
