| Abstract: | The membrane of the slow-releasing urea fertilizer was prepared mainly by corn starch, which was efficiency and green. In order to fulfill plants nutrition demand and obtain the better slow-releasing property, cross linking density was adjusted by the content of cross-linker. The results showed that the membrane of the slow-releasing urea fertilizer matched the Controlled Release Fertilizer Stand-ard formulate by Europe, which cumulative liquation rate is less than 30%. |
