| 摘 要： | 为了建立小麦/玉米轮作体系下的作物营养诊断推荐施肥技术体系，确定最佳施肥方案，对不同施肥方式下每一季作物进行硝态氮、产量、施肥量进行观测。结果表明，不同的施肥处理对作物产量影响显著，优化施肥产量提高2.73%~6.39%。不施肥处理条件下，二、三季作物产量显著降低，四季作物减产幅度趋于平衡；长期优化施肥使0~60 cm土壤硝态氮含量维持在同一个水平，而长期习惯施肥则使土壤硝态氮含量有增高的趋势；长期不施肥使土壤硝态氮含量稳定在较低水平；优化施肥节约化肥36.84%~52.97%。上述三种施肥方式以优化施肥最佳。

| Abstract: | Experiments were carried out on the Mazhuang town of Taian from 2004 to 2006. To based the technique system that it finished by diagnosing crop nutrition and commending fertilization under winter wheat and summer maize rotational cultivation and ensure the best fertilization project, it tested the nitrate-N and yield and fertilization quantity of every quarterly crop under different fertilization .The results showed that different fertilization had significant influence on the yield of crop, Optimize fertilization increased 2.73%~6.39% on the yield of crop. No fertilizer reduced the yield significantly for the second and the third seasons, the extent of the reduction of output went to balance on the forth season; Long-term optimize fertilization make the nitrate-N of the soil at the same level in 0~60cm, but custom fertilization had improved the content of he nitrate-N, and subsoil was polluted latently; Long -term no fertilization made the he nitrate-N of the soil keep lower level; Optimize fertilization economized fertilizer 36.84%~52.97%. The optimize fertilization was the best in above three fertilization fashion. |
