| 摘 要： | 施用ZnO 4.2kg/hm~2对玉米N、K元素的吸收利用存在极显著协和作用,可分别提高N、K肥料利用率35.84％和141.07％,增产7.63％,籽粒蛋白质、脂肪、淀粉和全糖含量分别增加5.63％、5.37％、2.69％和2.29％。Zn对P的吸收利用是拮抗作用,施Zn肥显著降低P肥利用率。

| Abstract: | The application of ZnO 4.2kg/hm2 has a very obvious synergism function on N and K absorption and utilization of maize,and can increase the fertilizer utilization rates of N and K by 35.84% and 141.07% respectively,thus increasing the yield by 7.63%,and can also enhance the contents of protein,fat,starch and total sugar in corn grain by 5.63%,5.37%,2.69% and 2.29% respectively.Zn has an antagonistic action on P absorption and utilization,and decreases P utilization rate. |
