摘要：
A field study was conducted to determine the influence of dicyandiamide (DCD) on fertilizer N recovery from soil and rice (Oryza sativa L.) when 15N-labeled urea was applied preplant (20 g N m-2). Microplots consisted of polyvinyl chloride pipes, 20.3 cm in diameter, driven into the soil. `Newbonnet' rice was seeded, thinned to five plants per microplot, and flooded when the plants were at the four- to five-leaf stage of development. Soil and plant samples were analyzed for N every 7 d for 49 following application (plant samples beginning at 35 d) and then every 14 d. Fertilizer N recovered in the total plant increased significantly from 35 to 42 d, after which no further changes occurred.
