| 摘 要： | 通过田间试验研究了包膜肥料ZP氮素释放特点和在夏玉米上施用效果。结果表明:包膜肥料ZP氮素在土壤中的释放有效期可达80天左右,其释放动态大体可分为三个阶段,其中快速释放期在施入后24~42天。等氮量的不同施氮处理中,包膜肥料所占比例越高的处理玉米全生育期吸收氮素越多,产量越高,氮素的利用率也越高。全部施用包膜肥料的处理较全部供给尿素的处理氮肥利用率高出14.4%。

| Abstract: | The nitrogen release character of ZP coated fertilizer and its effect on summer maize were studied by field plot test.The result showed that: The nitrogen release period of coated fertilizer ZP lasted about 80 days,and the release curve of nitrogen was divided into three stages with the fastest one occurring between 26-42day after application.Of the different treats with equal quantity of nitrogen,the one mixed with higher proportion coated fertilizer ZP accumulated higher amount of nitrogen and got higher N-utilization rate;the one with 100% coated fertilizer ZP got 14.4% more N-utilization rate than that with 100% urea. |
