Effects of Reducing and Applying Slow Release Fertilizer on Yield and Fertilizer Utilization of Late Rice
Through field plot experiment,using single-season late rice Chunyou 927 as the material,the fertilizer utilization ra-tio of conventional fertilization and Kingenta Volfertile slow-release fertilizer was studied,and the influence of fertilizer on uti-lization ratio was comprehensively analyzed through yield,economic characters per plant and other indicators.The results showed that the utilization rates of nitrogen,phosphorus and potassium in Jin Zhengda Wofute slow-release fertilizer were 8.1％,0.58％and 0.08％higher than those in conventional fertilization,respectively.The yield in slow-release fertilizer appli-cation area was still 7.75％higher than that in conventional fertilization area when the total amount of chemical fertilizer input was reduced by 17.9％.Wofute slow-release fertilizer had obvious effects on forming effective panicles and improving seed setting rate of late rice.
