| 英文摘要 | application of controlled-release nitrogenous fertilizers can improve the efficiency of fertilizers and reduce the environmental pollution. controlled-release urea (coated urea) is one of the controlled-release nitrogenous fertilizers developed quickly in the recent years. the rate of controlled-release urea pervasion through membrane is the most important index of the capacity of controlled release. there is a maximum absorption at lambda=426 nm with complex in acidic solution, using p-dimethylaminozenzaldehyde as color reagent, and the absorbance exhibits a linear reponses to the urea concentration over the range of 7. 5-210 mu g (.) ml(-1). the method for determining the rate of controlled-release urea pervasion through membrane was realized through determining the content of urea in the liquor, the recovery efficiency of the method is 96. 1%-103.9%. |
