英文摘要The continuous airflow enclosures with an acid trap method was widely used to investigate ammonia (nh3) volatilization in field; however, it could be time-consuming for the estimation of nh3 volatilization in field with the application of controlled-release urea (cru) because nh3 volatilization with cru application could occur during the entire crop growth period. an nh3 volatilization estimation method based on the modified jayaweera-mikkelsen (j-m) model combined with the sherlock-goh model was used to simulate nh3 volatilization in a paddy field after 255kgnha(-1) as cru (polymer-coated urea with the concentration of 43% nitrogen, 100% for basal) and urea (70% for basal, 30% for topdressing) during the rice growth period including flooded and non-flooded periods in wuxi, china. results indicated that nh3 volatilization can be modeled with the proposed measure because no significant difference (p<0.001) was observed between the simulated values and the observed values; the correlation coefficient (r(2)) was 0.615 for cru and 0.840 for urea during the flooded period, and 0.991 for cru and 0.946 for urea during the non-flooded period. compared with urea, nh3 volatilization was minimized by 43.2% with the application of cru based on simulated value within the rice growth period, which was 40.40kgnha(-1) for cru and 78.62kgnha(-1) for urea during the flooded period, and 5.52kgnha(-1) for cru and 2.33kgnha(-1) for urea during the non-flooded period. therefore, cru could be a promising nitrogen fertilizer to prevent nh3 losses in the rice paddies at the investigated area.
