The application discloses a method and integrated system for reducing carbon dioxide emission by using tenebrio molitor matrix fermentation, and the steps of the method comprise the following steps: putting tenebrio molitor in crop biomass for pretreatment to obtain a pile; stacking the pile and then carrying out fermentation; applying the generated carbon dioxide as gas fertilizer during the fermentation process; and using the fermented pile as a cultivation substrate. The method introduces tenebrio molitor into a crop biomass fermentation system, which can not only effectively degrade straw and realize agricultural waste resource utilization, but also significantly reduce the CO2 emission during the fermentation process. The integrated system based on the method couples crop biomass fermentation with greenhouse planting, recycles the generated CO2 as a carbon source for photosynthesis, and can regulate the CO2 supply according to the crop growth demand, thereby further realizing secondary CO2 emission reduction, effectively promoting crop growth, and constructing a low-carbon, high-efficiency and closed-loop ecological agricultural mode, which has significant environmental benefits, resource utilization benefits and production benefits.

The application discloses a biodegradable coated urea added with zirconium-based MOF nanocrystals with phosphatase activity and a preparation method and application thereof, and belongs to the technical field of fertilizers. The zirconium-based MOF nanocrystals with phosphatase activity are prepared, a solution of the zirconium-based MOF nanocrystals is mixed with urea and dried, polypropylene carbonate is used as a coating material, and then the biodegradable coated urea added with the zirconium-based MOF nanocrystals with phosphatase activity is prepared through a fluidized bed solvent method. The coated urea prepared in the application can realize nitrogen control release, hydrolyze soil organic phosphorus through the phosphatase activity of the Zr-MOF nanocrystals, realize the dual functions of continuous supply of nitrogen and in-situ activation of soil phosphorus, simultaneously meet the demand of crops for two core nutrient elements of nitrogen and phosphorus, significantly relieve the low-phosphorus stress of crops, promote the growth of the root system and the aboveground part of crops, and improve the biomass of crops.

The present application belongs to the technical field of bioengineering. The present application discloses a bacillus pumilus 21-14, the strain has been preserved in the China General Microbiological Culture Collection Center (CGMCC) on September 6, 2024, the center is abbreviated as CGMCC, the strain preservation center registration number is CGMCC NO.31892, the strain preservation date is September 6, 2024, and the address of the preservation unit is No.3, Beichen West Road, Chaoyang District, Beijing.
