摘  要:
通过研究尿素硝酸铵溶液对玉米各器官氮吸收和利用的影响规律,以期为生产中科学合理地施用尿素硝酸铵溶液提供理论依据。试验在田间条件下,设置N1(当地常规施肥对照,N为150 kg/hm2),N2(N为100 kg/hm2),N3(N为150 kg/hm2),N4(N为200 kg/hm2)4个处理,其中,N1所用氮肥为尿素,N2,N3,N4所用氮肥为尿素硝酸铵溶液,小区试验设计,3次重复。结果表明,茎、叶、苞叶、轴、籽粒氮吸收量N3处理分别比对照提高了12.72%,39.15%,35.04%,25.67%,13.55%,且差异显著;N4分别高于N3处理0.45,2.91,0.99,1.08,3.40 kg/hm2,但无显著差异;N2处理的叶、苞叶、轴、籽粒氮吸收量均显著低于N3处理;N3处理氮肥利用率比对照提高了15.05%,且差异显著,N4处理氮肥利用率与对照间无显著差异。综合分析认为,N3为最优处理。

摘  要:
The paper studied the effect of urea ammonium nitrate solution on nitrogen uptake and utilization in maize, at the same time, aimed to provide theoretical basis for scientific and rational application urea ammonium nitrate solution. The test under field conditions, set 4 treatment as N1(local conventional fertilization control, N as 150 kg/hm2), N2(N as 100 kg/hm2), N3(N as 150 kg/hm2),N4(N as 200 kg/hm2), the nitrogen fertilizer used in N1 was urea, and the nitrogen fertilizer used in N2, N3 and N4 was urea ammonium nitrate solution, plot experiment was designed and repeated 3 times. The results showed that N3 nitrogen absorption which in stem, leaf,loquat, axis, grain was higher than control as 12.72%, 39.15%, 35.04%, 25.67%, 13.55%, respectively, and had significant difference.N4 was higher than N3 treatment as 0.45, 2.91, 0.99, 1.08, 3.40 kg/hm2, respectively, but had no significant difference. N2 nitrogen absorption which in leaf, loquat, axis, grain was significant lower than N3. N3 nitrogen use efficiency was higher than control as 15.05%,and had significant difference, at the same time, there was no significant difference between N4 and control. Comprehensive analysis considers that the N3 is the best treatment.
