| 摘 要： | 基于小麦播前土壤的贮水量和不同的氮肥施用量,讨论其对冬小麦产量的影响。本试验设置了4个施氮水平,施氮量分别为0、50、150和250 kg/hm2。结果发现,在小麦播前土壤的贮水量为428 mm的条件下,随着氮肥施用量增加,小麦产量也增加。但N150和N250处理间差异不显著,因此我们推荐的施氮肥量为150 kg/hm2。

| Abstract: | The objectives of this experiment were to study effect of use content of N fertilizers on yield of winter wheat based on the pro-sown soil moisture content.There were four N levels were laid out which N content was 0,50,150,250 kg ha-1,respectively.We can obtain this conclusion from the experiment that yield of winter wheat were improved with increasing N content in the soil moisture content between 0 and 200cm soil depth was 428mm.However,the differences of yield both N150 and N250 treatments were very marginal.So,150 kg N ha-1was advocated to harvest higher yield. |
