| 摘 要： | 本文研究了微量元素铜在同样的氮肥量水平下对水稻生育的影响。结果表明,在氮、磷、钾配合施用的基础上,适量施用铜肥,可提高氮肥利用率,增加有效分蘖率,减少空秕率,提高抗稻瘟病、抗倒伏能力和产量。铜肥不仅促进水稻的氮素吸收,还促进氮素同化利用,氮肥量水平高时更为明显。

| Abstract: | The effects of Cu on rice at same level of N fertilizer were studied.The results showedthat besides N,P,and K fertilizers,a proper amcunt of Cu fertilizer could improve N utili-zation ratio and the effective tillering ability,reduce the rate of empty and shrivelgrains,and enhance the resistances to rice blast and lodging,and thus increasing theyield.Copper fertilizer promotes not only N absorption,but also N assimilation,especiallyat high level of N fertilizer. |
