为了确定机播小麦种肥施肥方式，进行了田间试验。选择肥料相对种子的施肥位置、施肥深度和施肥量作为3个因素，进行三因素两水平正交试验。结果表明，施肥深度对小麦产量的影响最大，肥料相对种子位于侧位或正位的位置对产量的影响次之，施肥量对产量影响最小。正交试验数据直观分析结果表明，最佳的施肥方式为正位深施肥，肥料与种子间距为5 cm 左右。因为施肥量对产量的影响相对其他因素很小，从降低投入和保护环境的角度综合考虑，应该适当减少化肥的施用量。

In order to ascertain optimal fertilizing method of seed manure for wheat , field experiment is conducted .The two-level-three-factor orthogonal experiments are done .The influence of main factors such as relative position of fertilizers, relative depth of fertilizers and fertilizer amount on wheat production are studied .The test results show that , effect of fertilization depth on wheat production is greatest , relative position of fertilizers follows , and effect of fertilizer a-mount on wheat production is least .Orthogonal intuitive analysis shows that the best position to apply fertilizer is vertical deep position and the distance between fertilizers and seeds is 5 centimeters .According to test results , the impact of in-creasing fertilizer on yield is small relative to other factors .Meanwhile , the heavy use of fertilizers brings pollution . Therefore , it should be appropriate to reduce the amount of fertilizer applied .
