Abstract:
Taking 8-year-old red globe grape as material,field experiments were carried out to evaluate the effects of different amounts and mixture ratio of two controlled release of nitrogenous fertilizer and common urea on grape yield and quality.The results showed that nitrogen fertilizer especially 2 kinds of controlled release nitrogen fertilizer significantly increased the yield of grapes.The nitrogen treatments had the range of increasing between 11.23% and 25.30% than the CK，grape yield and per ear weight，amount of nitrogen was positively correlated，per ear weight and yield of three kinds of nitrogen fertilizer varieties appear PCU>SPCU>PU>CK，and nitrogen fertilizer agronomic efficiency obviously enhanced.While the grape quality and single grain weight showed negatively trend related to the grape yield；controlled release nitrogen fertilizer mixed with a certain amount of ordinary urea could further improve the yield of grapes，two treatments of adding 30% and 50% urea compare with single controlled release nitrogen fertilizer，rate of yield increase was respectively 7.37%，5.79%，with good application effect.
