摘要
１９９１—１９９３年试验结果表明，在氮、磷肥基础上增施钾肥、锌肥、锰肥和叶面调肥，除拔节期前后苗高有所增加，单株黄叶数有所减少，植株体内钾、锰、铁、铜、锌的含量有所增加或保持平稳外，均未引起小麦单株性状的改变和产量构成的显著变化，故无显著的增产效果。
The experilental results in 1991 -1993 showed that fertilizer N,P application, combining with soil applying and foliage spraying of fertilizer K, Zn,Mn,didn't affect individual characteristics of wheat plant and yield components of wheat except for increasing the plant height,decreasing yellow leaf numbers increasing the concentration of K, Mn,Fe,Cu,Znin plant or keeping them ststable,the grain yield of spring wheat wouldn't have been increased significantly.
