The aim of this study was to evaluate the effects of microencapsulated urease inhibitor of n-butylthiophosphorotriamine(NBPT)microcapsules and nitrification inhibitor of 3，4-dimethylpyrazole phosphate (DMPP)microcapsules on greenhouse gases such as nitrous oxide(N2O)，methane(CH4)，carbon dioxide(CO₂)and corn yield of brown soil，and these effects were compared with their original forms of NBPT and DMPP，in order to verify the effectiveness of the new dosage form of inhibitor microcapsules and provide scientific basis for the preparation and improvement of inhibitor microcapsules. Brown soil was selected as the test soil to carry out the field experiment，and six treatments were set up，including no nitrogen fertilizer treatment(CK)，urea alone treatment(U)，urea with NBPT treatment(NBPT)，urea with DMPP treatment(DMPP)，urea with NBPT microcapsule treatment(Microencapsulated N)，and urea with DMPP microcapsule treatment(Microencapsulated D)，and the static box-gas chromatography was used for the determination of soil greenhouse gases during the reproductive period of maize. The emission fluxes of soil greenhouse gases during the reproductive period of maize were determined by static chamber-gas chromatography，and the integrated greenhouse gas potential(GWP)and greenhouse gas emission intensity(GHGI)were calculated. The ammonium nitrogen(NH4+-N)and nitrate nitrogen(NO^3--N)contents of the 0-20 cm surface soil in the experimental area of each treatment were collected and the yields of maize were measured during the maturity period of the maize to analyze the effects of the NBPT and DMPP microcapsules on the greenhouse gas emission，warming potential，soil mineral nitrogen(NH4+-N and NO^3--N)content，and maize yield in farmland. The results showed that，compared with traditional dosage forms of DMPP and NBPT，microencapsulated D and microencapsulated N showed more excellent results in many aspects. Compared with NBPT and DMPP，microencapsulated N and microencapsulated D significantly reduced N2O emissions by 10.67% and 21.43%，respectively，and microencapsulated D further significantly reduced N2O emissions by 17.91% compared with microencapsulated N. The microencapsulated N and microencapsulated D significantly increased cumulative uptake of CH4 in the brown soil by 57.88% and 51.13%，respectively，but the differences were not significant；and they significantly reduced CO₂ emissions by 6.61% and 5.36%，respectively，compared to NBPT and DMPP. The microencapsulated N and microencapsulated D significantly reduced GWP by 14.63% and 27.05%，and GHGI by 18.76% and 30.06%，as well as significantly increased corn yield by 5.06% and 4.28%，respectively，compared to NBPT and DMPP. And microencapsulated D significantly reduced GWP and GHGI by 19.23% and 18.80%，respectively，compared to those of microencapsulated N. Regarding soil mineral nitrogen content，both microencapsulated N and microencapsulated D reduced soil NH4+-N and NO^3--N content compared to NBPT and DMPP. In summary，compared with the traditional dosage forms DMPP and NBPT，microencapsulated D and microencapsulated N showed significant advantages in reducing greenhouse gas emissions，the comprehensive warming potential and greenhouse gas emission intensity，and increasing corn yield，and the overall effect of microencapsulated D was better than that of microencapsulated N. It could be seen that the new dosage form of inhibitor microcapsules had great application potential in agricultural production.
