为了摸索谷子高产施肥中氮肥的最佳组合和施肥方式，以谷子品种豫谷17号为研究对象，研究不同氮肥组合和施肥方式对谷子生长和产量的影响。在施氮总量不变的前提下，共设置7个处理：（1）氮肥为尿素，只作基肥；（2）氮肥为尿素，同时作基肥和追肥；（3）氮肥为碳酸氢铵，只作基肥；（4）氮肥为缓释硫酸铵，只作基肥；（5）氮肥为缓释硫酸铵和尿素，只作基肥；（6）氮肥为碳酸氢铵和缓释硫酸铵，只作基肥；（7）氮肥为碳酸氢铵和尿素，碳酸氢铵作基肥，尿素作追肥。结果表明，处理6谷子的叶面积、穗粗、单穗质量和产量最大，其中叶面积比处理1、2、3、4、5、7分别增加6.60％、1.77％、9.41％、1.07％、3.72％、3.41％，穗粗分别增加4.41％、2.23％、7.21％、2.33％、8.51％、0.65％，单穗质量分别增加6.99％、20.25％、26.36％、12.75％、20.31％、3.38％，产量分别增加9.58％、13.93％、21.57％、21.77％、23.08％、0.99％。

In order to find out the optimum combination of different nitrogen fertilizers and fertilization mode in high-yield fertilization of foxtail millet,the foxtail millet variety Yugu 1 7 was used to study the effects of different combinations of nitrogen fertilizers and fertilization modes on the growth and yield of foxtail millet.On the premise of total N amount fixed,seven treatments were set:(1 ) urea was used as base fertilizer only;(2 ) urea was used as base fertilizer and topdressing fertilizer;(3)ammonium bicarbonate was used as base fertilizer only;(4)slow release ammonium sulfate was used as base fertilizer only;(5 )slow release ammonium sulfate and urea were used as base fertilizer only;(6 )slow release ammonium sulfate and ammonium bicarbonate were used as base fertilizer only;(7)ammonium bicarbonate was used as base fertilizer and urea as topdressing fertilizer.The results showed that treatment 6 had the highest leaf area, ear diameter,single panicle weight and yield of foxtail millet,for treatment 6 leaf area was 6.60%, 1.7 7%,9.4 1%,1.0 7%,3.7 2% and 3.4 1% higher,ear diameter was 4.4 1%,2.2 3%,7.2 1%, 2.33%,8.51% and 0.65% higher,single panicle weight was 6.99%,20.25%,26.36%,12.75%, 20.31% and 3.38% higher,and yield was 9.58%,13.93%,21.57%,21.77%,23.08% and 0.99% higher than that of treatment 1,2,3,4,5,7,respectively.
