| 为了摸清甘肃省小麦施肥现状，为提高养分资源利用率与合理施肥提供依据，2008—2009年对甘肃省内定西、陇东、高寒区、沿黄灌区、河西等5个典型生态区农户用肥习惯及用肥量、用肥种类等进行了调查。结果表明：调查区小麦施氮、磷肥量普遍偏高，钾肥明显不足；不同生态区养分投入比例不协调，春小麦相对施肥比较适宜，冬小麦磷/氮比普遍偏高；小麦主要以施基肥或种肥为主，追肥量相对较少；肥料品种主要以尿素、磷酸二铵、碳酸氢铵和普通过磷酸钙为主，复合肥（小麦专用肥）有一定的施用面积，但总体比例还较低。 |
| 英文摘要: |
| In order to make clear the present condition of applying fertilizer of wheat in Gansu province, and to provide evidence for improve the nutrient resource utilization and the rational fertilization, an investigation of use fertilizer habits, the amount and Species of farmers fertilizer was carried out in five typical ecological area of the Dingxi, Longdong, High and Cold Areas, along the Yellow River Irrigation District, Hexi of Gansu province During 2008—2009, the results showed that application of N and P fertilizers is commonly higher, but K fertilizer is evidently insufficient in Gansu. The application ratio of nutritions is not rational, in detail, it is applicable to spring wheat, but not to winter wheat because the ratio of P and N is usually too high. The application of fertilizer to is mainly in planting period of wheat, and less in growing period. The fertilizer is mainly including urea, diammonium phosphate, ammonium bicarbonate, single superphosphate, and composite fertilizer(special fertilizer of wheat) is also used in some fields, but still in a lower ratio. |
