| 摘 要： | 在辛集马兰村进行的夏玉米平衡施肥试验研究表明,7个处理中,OPT处理的夏玉米产量和纯增效益最高;在氮、磷肥一定的条件下,增施钾肥可显著提高玉米产量;在一定条件下,磷钾肥投入增加的效益远远大于氮肥投入增加的效益,与磷肥相比,钾肥投入增加的效益较大。

| Abstract: | The balanced fertilization experiment in summer-corn d on e in Malan Village,Xinji County showed that the summer-corn yield and net retur n of the OPT treatment are the highest among the seven treatments.Improving the K fertilizer with adequate N and P fertilizer can remarkably increase the yield .Under certain conditions,the increased benefit by inputting P and K fertilizer is greater than N fertilizer,and comparing P and K fertilizer,K is greater than P. |
